    Ex-ante impact evaluation: case studies from Malawi, Bangladesh and Ghana (2021)
    WorldFish | Penang, Malaysia

    Description: This document presents ex-ante impact evaluations of research for development projects related to aquaculture in Bangladesh, Malawi and Ghana. The Ghana chapter also includes an ex-ante evaluation of a fisheries project. The case studies utilized preliminary versions of guidelines developed specifically for ex-ante evaluations of aquaculture and fisheries projects. The guidelines, found in A Practical Guide for Ex-Ante Impact Evaluations in Fisheries and Aquaculture, are designed to provide an approach for a qualitative examination of the potential for a project to deliver impacts. Using a conceptual framework based on the outcome focus of results-based management, the guidelines stress careful examination of the setting, internal consistency, a sound theory of change, and an examination of stakeholders’ interests and potential partnerships. The case study reports illustrate the variability with which the guidelines may be interpreted and applied. The different teams, operating with limited time and budget that constrained the collection of new data, were forced to utilize existing secondary data and information and consult with key stakeholders to complete their analyses. The varying levels of reporting reflect the differences among the cases in the amounts of existing information and variety of stakeholders potentially involved in the projects being examined.

    Description: In late 2012, a governance assessment was carried out as part of the diagnosis phase of rollout of the CGIAR Aquatic Agricultural Systems Program in Malaita Hub in Solomon Islands. The purpose of the assessment was to identify and provide a basic understanding of essential aspects of governance related to Aquatic Agricultural Systems in general, and more specifically as a case study in natural resource management. The underlying principles of the approach we have taken are drawn from an approach known as “Collaborating for Resilience” (CORE), which is based on bringing all key stakeholders into a process to ensure that multiple perspectives are represented (a listening phase), that local actors have opportunities to influence each other’s understanding (a dialogue phase), and that ultimately commitments to action are built (a choice phase) that would not be possible through an outsider’s analysis alone. This report begins to address governance from an AAS perspective, using input from AAS households and other networked stakeholders. We attempt to summarize governance issues that are found not only within the community but also, and especially, those that are beyond the local level, both of which may need to be addressed by the AAS program.

    Description: This guide was developed to document the process and activities that WorldFish staff have used and adapted as facilitators working with communities interested in marine resource management in Solomon Islands. It draws on the experiences from work conducted with FSPI and MFMR through ACIAR funded projects, with communities that had a primary interest in the management of coral reef fisheries. Since 2011 the process has been trialed and adapted further with communities interested in mangrove ecosystem management (through the MESCAL project). This guide is based on lessons about the process of a community developing, writing and implementing a management plan. This guide does not cover lessons about the outcomes of that management.

    Description: Lake Victoria fisheries face severe environmental stresses. Stocks are declining in a context of increasing population and growing demand for the lake’s resources. Rising competition between users is putting conservation goals and rural livelihoods at risk. While Uganda’s co-management policy framework is well-developed, key resources for implementation are lacking, enforcement is poor, and the relations between stakeholders are unequal. Poor rural resource users face significant challenges to effectively participate in fisheries decision-making. This case study demonstrates the progress that can be made using a collaborative approach to catalyze community-led actions linking public health, sanitation and environmental conservation in difficult circumstances, even over a relatively short time period. Multistakeholder dialogue can bring to light the sources of conflict, pinpoint governance challenges, and identify opportunities for institutional collaboration to address community needs. At the same time, the process can help build trust, confidence in collective action and public accountability.

    Description: Solomon Islands has a population of just over half a million people, most of whom are rural-based subsistence farmers and fishers who rely heavily on fish as their main animal-source food and for income. The nation is one of the Pacific Island Counties and Territories; future shortfalls in fish production are projected to be serious, and government policy identifies inland aquaculture development as one of the options to meet future demand for fish. In Solomon Islands, inland aquaculture has also been identified as a way to improve ood and nutrition security for people with poor access to marine fish. This report undertaken by a Worldfish study under the CGIAR Research Program on Aquatic Agricultural Systems explores the e potential role of land-based aquaculture of Mozambique tilapia in Solomon Islands as it relates to household food and nutrition security. This nutrition survey aimed to benchmark the foods and diets of households newly involved in small homestead tilapia ponds and their neighboring households in the central region of Malaita, the most populous island of all the provinces in Solomon Islands. Focus group discussions and semistructured interviews were employed in 10 communities (five inland and five coastal), four clinics, and five schools.

    Description: When different strains or breeds of a particular species are available, the best choice is seldom immediately obvious for producers. Scientists are also interested in the relative performance of different strains because it provides a basis for recommendations to producers and it often stimulates the conduct of work aimed at unraveling the underlying biological mechanisms involved in the expression of such differences. Hence, strain or breed comparisons of some sort are frequently conducted. This manual is designed to provide general guidelines for the design of strain comparison trials in aquaculture species. Example analyzes are provided using SAS and SPSS. The manual is intended to serve a wide range of readers from developing countries with limited access to information. The users, however, are expected to have a basic knowledge of quantitative genetics and experience in statistical methods and data analysis as well as familiarity with computer software. The manual mainly focuses on the practical aspects of design and data analysis, and interpretation of results.

    Description: Aquaculture production systems in developing countries are largely based on the use of unimproved species and strains. As knowledge and experience are accumulated in relation to the management, feeding and animal health issues of such production systems, the availability of genetically more productive stock becomes imperative in order to more effectively use resources. For instance, there is little point in providing ideal water conditions and optimum feed quality to fish that do not have the potential to grow faster and to be harvested on time, providing a product of the desired quality. Refinements in the production system and improvement of the stock used must progress hand in hand. In this paper we deal separately with genetic and non-genetic issues pertaining to the multiplication and dissemination of improved strains. The separation is somewhat arbitrary, and as will be evident from our discussion, there is frequent interaction between the two.

    Description: Egypt’s aquaculture production (921,585 tonnes in 2010) is by far the largest of any African country. The aquaculture sector, dominated by semi-intensive pond production of tilapia, makes a significant contribution to income, employment creation and food and nutrition security in the country, all of which are national priority areas given low per capita income levels, rising population, worsening food and nutrition security indicators, and official unemployment levels which have remained at around 10% for the last ten years. The Improving Employment and Income through Development of Egypt’s Aquaculture Sector (IEIDEAS) project funded by the Swiss Agency for Development and Cooperation (SDC) is a three-year project which commenced in December 2011, and which aims to support the development of the aquaculture sector in Egypt so as to increase productivity, profitability, and employment in the sector, and the nutritional status of poor consumers. This report represents the output of a short two-week study to better understand the market for Egyptian farmed fish. The intention of the study was to provide an output which would cut-across, and potentially benefit, all five of the project outcomes.

    Description: Use of manufactured feeds in aquaculture in Bangladesh has grown rapidly over the last five years. More than 1 million tonnes of commercially formulated feeds and 0.3-0.4 million tonnes of farm-made feeds were produced in 2012, and sectoral growth is projected to increase substantially over the medium term. This working paper summarizes findings from a study, conducted as part of the WorldFish/USAID “Feed the Future-Aquaculture” project in 2012, assessing the current status of the aquaculture feed sector in Bangladesh. Fish feed value chains, market trends, ingredients and formulation systems, farm feeding practices, ancillary services and feed regulations were investigated. The study identifies a number of entry points for interventions in the sector, and investments which would improve feed quality and farmer access to better feeds and support the growth of sustainable aquaculture.

    Description: The CGIAR Research Program (CRP) Aquatic Agricultural Systems (AAS) will target five countries, including Solomon Islands. The proposed hubs for Solomon Islands were to cover most provinces, referencing the Western, Central and Eastern regions. Scoping of the initial ‘Central’ hub was undertaken in Guadalcanal, Malaita and Central Islands provinces and this report details findings from all three. As scoping progressed however, it was agreed that, based on the AAS context and priority needs of each province and the Program’s capacity for full implementation, the Central Hub would be restricted to Malaita Province only and renamed “Malaita Hub”. Consistent in each AAS country, there are four steps in the program rollout: planning, scoping, diagnosis and design. Rollout of the Program in Solomon Islands began with a five month planning phase between August and December 2011, and scoping of the first hub began in January 2012. This report, the second to be produced during rollout, describes the findings from the scoping process between January and June 2012. This report marks the transition from the scoping phase to the diagnosis phase in which output from scoping was used to develop a hub level theory of change for identifying research opportunities. Subsequent reports detail in-depth analyses of gender, governance, nutrition and partner activities and discuss Program engagement with community members to identify grass-roots demand for research.

    Description: The commercial aquaculture feed industry in Egypt is growing at a rapid rate. As a result, the number of fish feed mills has increased from just 5 mills producing about 20,000 t per year in 1999, to over 60 mills with a current production estimate of 800,000–1,000,000 t/year. The performance of the aquafeed industry in Egypt is not well understood, as the value chain structure has not yet been mapped. This study aims to assess the status of the fish feed sector in Egypt, with an emphasis on: mapping and understanding fish feed value chains, describing the main actors and stakeholders within the chain, assessing value chain performance, identifying major strengths and weakness of the sector, and suggesting appropriate actions, management and development strategies.

    Description: Concerns about perceived loss of indigenous materials emerged from multiple stakeholders during consultations to plan and design the CGIAR Research Program on Aquatic Agricultural Systems for the Borotse hub in Zambia’s Western Province. To come to grips with and address the concerns, the AAS Borotse hub program of work included an assessment of agrobiodiversity to inform community-level and program initiatives and actions. The agrobiodiversity assessment comprised three components: key informant and expert surveys complemented by review of grey and published literature, focus group discussions in the communities, and individual household surveys. This working paper reports the findings from assessments of agrobiodiversity resources in the Borotse hub by key informants and local experts working in government ministries, departments and agencies, and non-governmental organizations operating in the communities. This working paper covers the following topics: agriculture in the Borotse flood plain; major agricultural land types in the Borotse flood plain; soils and their uses; production systems; crops, including the seed sector and ex-situ resources; indigenous materials collected from the wild, including non-perennial and perennial plants, aquatic plants, and forest biodiversity; fish resources, including both capture fisheries and aquaculture; livestock resources; dietary diversity; and indigenous and local knowledge on management systems.

    Description: Where natural resources are a key component of the rural economy, the ability of the poor to realize their visions for the future depends significantly on institutional structures that govern resource access and management. This case study reports on an initiative on the shores of Lake Kariba in Zambia, where lakeshore residents face competition over fishing, tourism, and commercial aquaculture. Multistakeholder dialogue produced agreements with investors and increased accountability of state agencies and traditional leaders, enabling communities to have greater influence over their futures through improvements in aquatic resource governance. The report documents the rationale for the approach followed and steps in the capacity-building process, discusses obstacles encountered, and identifies lessons for policymakers and practitioners seeking to implement a similar approach.

    Description: The Republic of Kiribati is a vast South Pacific island group with one of the largest exclusive economic zones (EEZs) in the world. Kiribati waters support a wealth of marine fisheries activities. These activities occur in oceanic, coastal and inshore environments and range from large, foreign, industrial-scale oceanic fishing operations to small-scale, domestic, inshore subsistence fisheries, aquaculture and recreational fisheries. Kiribati has developed a framework of domestic and international governance arrangements that are designed to sustainably manage its wealth of marine resources. The report provides background information for fisheries projects in Kiribati that aim to build food security, improve artisanal livelihoods and strengthen community engagement in fisheries governance. It provides information on the current status of Kiribati fishery resources (oceanic and coastal), their current governance and future challenges. Fish and fisher alike pay little heed to maritime boundaries and bureaucratic distinctions. This report covers both sides of the oceanic/coastal boundary because of the I-Kiribati communities’ interest in oceanic fisheries such as tuna and their heavy dependence on its fisheries resources for food security and economic development. The report focuses on two potential pilot sites for community-based fisheries management projects: North Tarawa and Butaritari.

    Description: Conflict management is an intrinsic element of natural resource management, and becomes increasingly important amid growing pressure on natural resources from local uses, as well as from external drivers such as climate change and international investment. If policymakers and practitioners aim to truly improve livelihood resilience and reduce vulnerabilities of poor rural households, issues of resource competition and conflict management cannot be ignored. This synthesis report summarizes outcomes and lessons from three ecoregions: Lake Victoria, with a focus on Uganda; Lake Kariba, with a focus on Zambia; and Tonle Sap Lake in Cambodia. Partners used a common approach to stakeholder engagement and action research that we call “Collaborating for Resilience”. In each region, partners assisted local stakeholders in developing a shared understanding of risks and opportunities, weighing alternative actions, developing action plans, and evaluating and learning from the outcomes. These experiences demonstrate that investing in capacities for conflict management is practical and can contribute to broader improvements in resource governance.

    Description: Poor rural consumers benefit from Egypt’s aquaculture sector through access to small and medium-sized farmed tilapia sold by informal fish retailers, many of whom are women. In fact, informal fish retail is the main, if not only, segment of the farmed fish value chain where women are found. This report aims to inform current and future strategies to improve conditions in informal fish retail by understanding in more depth the similarities and differences in employment quality and outcomes across different fish retailers. It is particularly focused on identifying whether and how gender inequality influences different dimensions of the work, and whether women and men have similar outcomes and employment conditions. This knowledge will help to design interventions to overcome gender-based constraints, as well as approaches that address shared obstacles and include both women and men in gender-responsive ways to ensure that all of those involved in the sector benefit.

    Description: WorldFish and the International Centre for Climate Change and Development (ICCCAD) held a two-day workshop on the topic of Weather Index-Based Insurance: Lessons Learned and Best Practices for Bangladesh. Weather index insurance is based on a predefined weather event which when triggered ensures automatic payout to farmers who have taken out insurance. For example, the climatic trigger could be a predefined consecutive number of days where rainfall is below a set level or when the floodwater level reaches above a certain point. Index insurance has been operating for about 10 years in many countries but is still at an early stage in Bangladesh, where there are two schemes currently being piloted and three other projects being developed. The aim of the two-day workshop was twofold: to ascertain the present state of index insurance in Bangladesh and elsewhere, and to work together to identify ways forward.

    Description: Fish play a crucial role in the Bangladeshi diet, providing more than 60% of animal source food, representing a crucial source of micro-nutrients, and possessing an extremely strong cultural attachment. Fish (including shrimp and prawn) is the second most valuable agricultural crop, and its production contributes to the livelihoods and employment of millions. The culture and consumption of fish therefore has important implications for national food and nutrition security, poverty and growth. This review examines the current state of knowledge on the aquaculture sector and fish consumption in Bangladesh, based on extensive analysis of secondary sources (including unpublished data unavailable elsewhere), consultation with various experts and specially conducted surveys.

    Description: This publication is based on materials covered and outputs generated during the Workshop on Risk Assessment Methodologies and Tools for Aquaculture in Sub-Saharan Africa, which was jointly held by WorldFish and FAO in Siavonga, Zambia on 28 June - 2 July 2010. The workshop was delivered as a training exercise to 17 participants from seven sub-Saharan countries and was designed to highlight current methodologies and tools available for environmental risk analysis in aquaculture development. A key focus of the workshop was to encourage participants to consider hypothetical but realistic scenarios and to discuss issues relevant to evaluating the environmental risks of a given activity or scenario. This publication presents selected scenarios from the workshop and the outcomes of the deliberative process as developed by the participants. This publication is factual but not comprehensive, therefore any statements or estimations of risk do not represent the actual risks arising from the described scenario. It is intended to serve as an easily readable introduction to risk analysis, highlighting worked examples that will provide guidance on how a risk analysis may be approached in a similar situation.

    Description: The Egyptian aquaculture industry provides more than 100,000 full-time or part-time jobs and produces the country’s least-expensive farmed animal protein. Thus, aquaculture plays an important role in both sustaining livelihoods and improving the diet quality and nutritional health of Egyptians, including a significant proportion of the 25.5% who are resource-poor. Recognizing this dual role, WorldFish has promoted sustainable growth in Egyptian aquaculture for more than 20 years. Through its work, WorldFish has identified a lack of quality data about fish consumption preferences and practices. Eager to fill this knowledge gap, WorldFish partnered with the Environment and Development Group (EDG) to study consumption of fish, red meat and poultry among the resource-poor in Egypt. This study aimed to characterize current consumer preferences for and consumption patterns of animal-source foods, comparing red meat, poultry and fish. The resulting data is meant to contribute to a better understanding of what drives demand for fish among the resource-poor in Egypt, allowing value chain actors to more successfully market their products to this segment of the population.

    Description: During the rollout of CGIAR Research Program on Aquatic Agricultural Systems (AAS) in Tonle Sap in 2013, water management was highlighted as one of the key development challenges. With limited capacity to regulate water, the situation oscillates between too much water in the wet season and too little water in the dry season. Access to and availability of water were seen by local communities as major limitations for aquatic and agricultural production, impacting on functions that include the lake fishery, intensive (dry season) rice crops, recession rice, rainfed rice and floating rice by the lakeside. For both fish and rice production, water and water management are determined principally by the natural flooding of the Tonle Sap Lake. This study is based on a community survey on water access, availability and management and was conceived out of the AAS consultation process and was developed to help identify existing practices in water use and management, as well as best practices where lessons can be learned and promising activities scaled out to other communities. The community survey also aims to understand, identify and analyze constraints and opportunities related to water, and includes a gender perspective to better understand the role of women in water management and use.

    Description: Aquatic agricultural systems in developing countries face increasing competition from multiple stakeholders operating from local to national and regional scales over rights to access and use natural resources—land, water, wetlands, and fisheries-essential to rural livelihoods. A key implication is the need to strengthen governance to enable equitable decision-making amidst such competition, building capacities for resilience and transformations that reduce poverty. This paper provides a simple framework to analyze the governance context for aquatic agricultural system development focused on three dimensions: stakeholder representation, distribution of power, and mechanisms of accountability. Case studies from Cambodia, Bangladesh, Malawi/Mozambique, and Solomon Islands illustrate the application of these concepts to fisheries and aquaculture livelihoods in the broader context of intersectoral and cross-scale governance interacti

    Description: The overall objective of the project is the reduction of poverty in rural areas of Solomon Islands through creation of livelihoods based on sustainable aquaculture. This fits within the over-arching goals of the WorldFish Center in the Pacific to reduce poverty and hunger in rural communities, and with the Ministry of Fisheries and Marine Resources (MFMR) to stimulate rural development and to develop aquaculture. It has been recognised that the nature of the pearl farming industry means that a high chance of success requires a long term investment from an established pearl farming organisation. This project has been specifically designed to compile the elements of a pre-feasibility study to provide offshore pearl companies with sufficient information to investigate the potential for long-term investment in pearl farming in Solomon Islands. This report also includes the following 6 appendices: Appendix I) Past research and development on black-lip pearl oysters in Solomon Islands; Appendix II) Suitability of habitats in the Solomon Islands and other regions of the Pacific for growth of black-lip and silver-lip pearl oysters; Appendix III) Water temperature and cyclone frequency in the Solomon Islands and other key regions of the Pacific: implications for pearl farming; Appendix IV) Abundance, size structure and quality of silver-lip pearl oysters in Solomon Islands; Appendix V) Solomon Islands: the investment climate for pearl farming; Appendix VI) Pearl farming policy and management guidelines.

    Description: Aquatic agricultural systems (AAS) are systems in which the annual production dynamics of freshwater and/or coastal ecosystems contribute significantly to total household income. Improving the livelihood security and wellbeing of the estimated 250 million poor people dependent on AAS in Bangladesh, Cambodia, the Philippines, the Solomon Islands and Zambia is the goal of the Worldfish Center-led Consortium Research Program (CRP), “Harnessing the development potential of aquatic agricultural systems for development.” One component expected to contribute to sustainably achieving this goal is enhancing the gender and wider social equity of the social, economic and political systems within which the AAS function. The CRP’s focus on social equity, and particularly gender equity, responds to the limited progress to date in enhancing the inclusiveness of development outcomes through interventions that offer improved availability of resources and technologies without addressing the wider social constraints that marginalized populations face in making use of them. The CRP aims to both offer improved availability and address the wider social constraints in order to determine whether a multi-level approach that engages with individuals, households and communities, as well as the wider social, economic and political contexts in which they function, is more successful in extending development’s benefits to women and other excluded groups. Designing the research in development initiatives to test this hypothesis requires a solid understanding of each CRP country’s social, cultural and economic contexts and of the variations across them. This paper provides an initial input into developing this knowledge, based on a review of literature on agriculture, aquaculture and gender relations within the five focal countries. Before delving into the findings of the literature review, the paper first justifies the expectation that successfully achieving lasting wellbeing improvements for poor women and men dependent on AAS rests in part on advances in gender equity, and in light of this justification, presents the AAS CRP’s conceptual framew

    Description: This study estimated the adoption rate of integrated aquaculture-agriculture (IAA) technologies in Bangladesh and their impact on poverty and fish and food consumption in adopting households. We used a novel, simulation-based approach to impact assessment called Tradeoff Analysis for Multi-Dimensional Impact Assessment (TOA-MD). We used the TOA-MD model to demonstrate how it is possible to use available data to estimate adoption rates in relevant populations, and to quantify impacts on distributional outcomes such as poverty and food security, thus demonstrating ex ante the potential for further investment in technology dissemination. The analysis used baseline and end-of-project survey data from WorldFish-implemented Development of Sustainable Aquaculture Project (DSAP), promoting IAA. This dataset was used to simulate adoption and assess its impacts on poverty and food security in the target population. We found that, if adopted, IAA had a significant positive impact on reducing poverty and improving food security and income.

    Description: Increases in fish demand in the coming decades are projected to be largely met by growth of aquaculture. However, increased aquaculture production is linked to higher demand for natural resources and energy as well as emissions to the environment. This paper explores the use of Life Cycle Assessment to improve knowledge of potential environmental impacts of future aquaculture growth. Different scenarios of future aquaculture development are taken into account in calculating the life cycle environmental impacts. The environmental impact assessments were built on Food and Agriculture Organization statistics in terms of production volume of different species, whereas the inputs and outputs associated with aquaculture production systems were sourced from the literature. The matrix of input-output databases was established through the Blue Frontiers study.

    Description: There are increasing requirements for impact assessment by development partners in order to increase the accountability and effectiveness of research and development projects. Impact assessment research has been dominated by conventional economic methods. This context challenges agricultural research organizations to develop and apply alternative impact assessment methods incorporating economic, social, and environmental impact components. In this study, we use the Tradeoff Analysis for Multi-Dimensional Impact Assessment (TOA-MD) model to evaluate the impact of integrated aquaculture-agriculture (IAA) adoption in Malawi. The study demonstrated that with a minimal data set, the TOA-MD model can be applied to predict and assess the adoption rates of new technologies and practices as well as their economic and non-economic impacts.

    Description: Small indigenous fish species (SIS) are an important source of essential macro- and micronutrients that can play an important role in the elimination of malnutrition and micronutrient deficiencies in the populations of many South and Southeast Asian countries. Of the 260 freshwater fish species in Bangladesh, more than 140 are classified as SIS and are an integral part of the rural Bangladeshi diet. As many SIS are eaten whole, with organs and bones, they contain high amounts of vitamins and minerals, including calcium, and iron and zinc. Some SIS, such as mola, are also rich in vitamin A. SIS are often cooked with vegetables and a little oil, so they contribute to the food diversity of the rural poor.SIS are recognized as a major animal-source food group, contributing to improved food and nutrition security and livelihoods of the people of South and Southeast Asia. The purpose of this workshop is to bring together policy makers, extension agents, researchers, non-governmental and development organizations to share knowledge about small fish, their contribution to better nutrition, production technologies, and strategies for wider dissemination of pond culture and wetland based-production and conservation technologies. The workshop is expected to generate ideas for further research and development of sustainable technologies for production, management and conservation of SIS for the benefit of the people of Bangladesh as well as the South and Southeast Asian region.

    Description: Cambodia’s recent freshwater fishery sector reform, instigated at the top level of government, is one of the country’s most significant contemporary policy developments addressing natural resources management and rural development. Implemented in two main waves, the reforms culminated in the complete removal of inland commercial fishing lots. Yet serious problems still need to be addressed, including reportedly widespread illegal fishing, difficulties in protecting critical habitats, and competition among state agencies over resource management authority. This report summarizes the context of the recent fishery reforms, analyzes challenges and opportunities for policy implementation after the reforms, and details the outcomes of local institutional innovations in Kampong Thom Province, followed by a discussion of the implications for ongoing efforts aimed at reducing resource conflict and building livelihood resilience.

    Description: In many countries, resource conflict is a leading risk to livelihoods. For some communities, it is a matter of survival. Yet, many development interventions aiming to address these challenges fail or fall far short of their potential. Common reasons include conflicting agendas, power and politics; poor local commitment and leadership; lack of coordination; plus high costs and low sustainability, as programs often unravel when development finance ends. Overcoming these obstacles requires a shift from typical approaches to planning, implementing and evaluating rural development and natural resource management initiatives. This manual introduces one approach to achieving such breakthroughs in collective action, called Collaborating for Resilience. The manual presents a set of principles and field-tested guidance on exploring the potential for collaboration, facilitating dialogue and action, evaluating outcomes, and sustaining collaboration over time.

    Description: This study evaluates the performance of a wide range of aquaculture systems in Bangladesh. It is by far the largest of its kind attempted to date. The purpose of this study was to identify and analyze the most important production systems, rather than to provide a nationally representative overview of the entire aquaculture sector of Bangladesh. As such, the study yields a huge amount of new information on production technologies that have never been thoroughly researched before. The study reveals an extremely diverse array of specialized, dynamic and rapidly evolving production technologies, adapted to a variety of market niches and local environmental conditions. This is a testament to the innovativeness of farmers and other value chain actors who have been the principal drivers of this development in Bangladesh. Data was collected from six geographical hubs. This survey was conducted from November 2011 to June 2012. Technological performance in terms of detailed input and output information, fish management practices, credit and marketing, and social and environmental issues were captured by the survey questionnaire, which had both open and closed format questions. The study generated insights that enable better understanding of aquaculture development in Bangladesh.

    Description: Fish is crucial to food and nutrition security in Solomon Islands, and demand is expected to increase due to a growing population. However, it is projected that current capture fisheries production will not meet this growing demand. Aquaculture has the potential to mitigate the capture fishery shortfall, and the Government of Solomon Islands is prioritizing aquaculture as a solution to meet future food and income needs. Aquaculture in Solomon Islands is still in early development. Mozambique tilapia (Oreochromis mossambicus) is farmed for household consumption, but its prolific reproductive rate and resulting slow growth limit its potential as a commercial aquaculture species. More productive fish species that are not indigenous to Solomon Islands but are successfully farmed overseas could be introduced; however, such a decision needs to take into account the potential ecological or social impacts. For land-based pond aquaculture, the only indigenous species that has been farmed extensively elsewhere is milkfish (Chanos chanos). This report presents a feasibility assessment for milkfish farming in Solomon Islands. It synthesizes the current knowledge about milkfish farming and presents results of a 4-year study on the potential for milkfish aquaculture in Solomon Islands.

    Description: The fisheries sector in Cambodia contributes 8%–12% to national GDP and 25% - 30% to agricultural GDP, with an estimated 4.5 million people involved in fishing and associated trades. Fish and other aquatic animals are important food sources, contributing an estimated national average of 60% - 70% of total animal protein intake. Of the 2013 total fish production, 550,000 metric tons were harvested from freshwater habitats, of which rice field fisheries and small-scale family fisheries contributed approximately 20%. The productivity and value of rice field fisheries to households in rural Cambodia has been highlighted in a number of previous studies. The Fisheries Administration of the Ministry of Agriculture, Forestry and Fisheries plans to increase productivity from rice field fisheries and aquaculture at an annual rate of 15% to maintain supply for a growing population. This report draws mainly on the baseline and monitoring data from the Rice Field Fisheries Enhancement Project (RFFEP) during its implementation between 2012 and 2014. Reference is also made to the Fish on Farms project to highlight the relative contribution of fish from small-scale aquaculture compared to wild-caught fish.

    Description: The Swiss Agency for Development and Cooperation (SDC)-funded Improving Employment and Income through Development of Egypt’s Aquaculture Sector (IEIDEAS) project was implemented by WorldFish in partnership with CARE Egypt and the Egyptian Ministry of Agriculture and Land Reclamation from 2011 to 2014 and later extended to November 2015. The project focused on four governorates with significant aquaculture production (Kafr El Sheikh, Behera, Sharkia and Fayoum) and one governorate (El Mineya), where aquaculture was a new activity. The project was based on a value chain analysis conducted by WorldFish in September 2011 that identified the aquaculture value chain as a significant employer, particularly in rural areas. The analysis suggested that there was scope to increase employment of youth and women in the aquaculture sector The main objective was to increase aquaculture production by 10% and create 10,000 jobs. Other objectives included improving profitability for existing producers, securing employment for women fish retailers, expanding aquaculture in El Mineya and improving the policy environment for aquaculture.

    Description: The goal of WorldFish’s research on markets and value chains is to increase the benefits to resource-poor people from fisheries and aquaculture value chains by researching (1) key barriers to resource-poor men, women and other marginalized groups gaining greater benefits from participation in value chains, including barriers related to the availability, affordability and quality of nutrient-rich fish for resource-poor consumers; (2) interventions to overcome those barriers; and (3) mechanisms that are most effective for scaling up of value chain interventions. This paper aims to promote and document learning across WorldFish’s value chain research efforts in Asia and Africa. It has three main objectives: (1) to take stock of WorldFish’s past and ongoing research on value chains; (2) to draw out commonalities and differences between these projects; and (3) to provide a synthesis of some learning that can guide future work.

    Description: The Association of Southeast Asian Nations (ASEAN) has emerged as a global fish producer, owing to the rapid growth of aquaculture in Southeast Asia and its large offshore fishing fleet. Fish is a regional commodity that is traded globally, and this region is at the frontline of the global trend toward meeting seafood demand by 2050. Fisheries and aquaculture are increasingly becoming a primary source of protein and micronutrients, foreign exchange, livelihoods and well-being for the population in the region. Therefore, it is imperative for ASEAN decision-makers to enhance policies nationally and regionally to maximize the synergies between socioeconomic development and protecting natural resources and the environment in the region. This paper presents a baseline (business-as-usual) projection of fish supply, net trade, consumption and nutrition in the ASEAN region to 2050.

    Description: The acquisition or loss of Clinostomum tilapiae parasites by Oreochromis niloticus was studied. Four groups of 25 healthy fishes were stocked in the upper part of serial experimental ponds, while another four groups of 25 infected fishes were also stocked at the rear part of the serial experimental ponds. All the groups were fed at 3% body weight with the same compounded fish feed. Acquisition or loss of parasites and growth was monitored for a period of six months. The mean relative growth rate was 11.04kg/month for the healthy fishes and 5.62g/month for the infected fishes. The mean specific growth rate was 38.75% and 31.25% for the healthy and infected groups respectively. However the results were not statistically significant (p 〉 0.05). The parasite did not multiply on the host body rather the infection rate reduced from 100% to between 44 and 78%, parasite burden was reduced from an average of 3 per fish to 2.25 while the healthy fish acquired the parasite and the average burden was 2.15. The mean values of the prevailing water quality parameters were within the optimum range acceptable in fish culture systems in the tropics.

    Description: A completely randomised design with three replicates was used for an experiment conducted to study the profitability of vitamin C inclusion into the ration formulation for Heterobranchus longifilis. Six different levels 0, 50, 100, 150, 200 or 250 mg of L-ascorbic acid (vitamin C) kg-1 diet was included in a 42.5% crude protein basal diet and fed to triplicate groups of twenty fingerlings. The groups fed diets with vitamin C had statistically significant (P〈0.05) higher final weight than the group fed the control diet without vitamin C at the end of twenty weeks study, Feed consumed was significantly (P〈0.05) lower in the group fed diet without vitamin C. There was a significant (P〈0.05) difference between the groups fed 0 and 50 mg vitamin C kg-1 diets, but no significant (P〉0.05) difference between the groups fed diets with 100, 150, 200 and 250 mg vitamin C kg-1 diet on this parameter. Mortality was significantly (P〈0.05) higher in the groups fed diet without vitamin C while there was no significant difference (P〉0.05) between the fish fed the diets with respective graded levels of vitamin C. The thiobarbituric acid reactive substance (TBARS) of the liver and whole body of fish was significantly (P〈0.05) higher in fish fed diet devoid of vitamin C. Cost per kilogram of fish base on feed input was significantly (P〈0.05) higher in the group fed diet without vitamin C than those enriched with vitamin C. However, within groups fed with vitamin C cost per kg of fish was significantly (P〈0.05) decreasing in the following order: diet 2〉 diet 6〉 diets 4, 5, and 3. There was no significant difference (P〉0.05) between fish fed diets 3, 4 and 5 with respect to cost per kilogram of fish. This study vividly showed that there is no alternative to the use of a complete diet with vitamin C in an intensive practical farming of H. longifilis geared towards optimum profit maximisation in terms of feed as one of the variable input.

    Description: The growth performance and nutrient utilization in Clarias gariepinus fingerlings fed cooked breadfruit (Artocarpus altilis) seed meal based diet as a replacement for maize, investigated for 8 weeks. Five (5) diets of breadfruit seed meal substituted for maize at different levels of inclusion (0%; 25%; 50%; 75% and 100%) were fed to the fingerlings at 5% body weight twice daily in hapa of 1m x 1m x 1m. The hapas wee submerged in a pond and each hapa stocked with 20 fingerlings of mean weight of 5.8~c0.00g. Evaluation of growth parameters nutrient utilization of the experimental diets showed that there was no significant difference (P〉0.05) in mean final weight (MFW); specific growth rate (SGR); feed conversion rate (FCR) protein efficiency ratio (PER) and apparent net protein utilization (ANPU) among the treatments. The results suggested a net advantage of replacing dietary maize with cooked breadfruit seed meal for Clarias gariepinus fingerlings at 50% and above levels of inclusion under the condition of the experiment.

    Description: In order to compare the effect of raw, cooked, toasted and extruded soybean meals on the growth and nutrient utilization of Heterobranchus longifilis fingerlings, 120 pure Heterobranchus longifilis fingerlings were purchased at the National Institute for Freshwater Fisheries Research (NIFFR) improved genetic fish hatchery and randomly allocated into four different treatments with two replicates each with 15 fingerlings in 8 aquaria tanks. Four different diets containing 40% crude protein each were compounded and fed to the fish at 5% body weight for 56 days. At the end of the feeding trials, growth performance and nutrient utilization were evaluated. The results revealed that fish fed toasted soybean-based diets had highest mean weight gain (MWG) of 16.39g, specific growth rate (SGR) of 2.03%/day, and food conversion ratio (FCR) of 2.18. The fingerlings fed the extruded soybean-based diet gave the least growth performance. It could be concluded in practice, that toasted soybean-based diet is optimal for growth of Heterobranchus longifilis fingerlings.

    Description: 200 fingerlings of African catfish (Clarias gariepinus) of average weight of 22.8~c0.04g were used to investigate the nutritive value of Pawpaw (Carica papaya) leaf-based diets. Five (5) isocaloric and iso-nitrogenous diets containing fishmeal protein at a rate of 0%, 25%, 50%, 75%, and 100% along with the pawpaw leaf were formulated. The diet without the pawpaw leaf meal serves as the control. The fish fingerlings were fed at 5% body weight per day for 56 days in plastic bowls. It was observed at the end of the experiment that pawpaw leaf meal was suitable as a protein supplement when incorporated at 50% replacement. The body weight gain, specific growth rate (SGR) and food conversion ratio (FCR) values of 18.68g, 1.07%/ day and 4.72 respectively were highest in diet with 50% replacement closely followed by diet with 25% replacement. Based on the results, it could be recommended that in practice 50% replacement of pawpaw leaf meal with fish meal is optimal in practical diet of African catfish (Clarias gariepinus) fingerlings. Nevertheless, complete replacement of pawpaw leaf meal decreases growth rate and should not be used in Clarias gariepinus fingerlings.

    Description: An experimental growth trial in floating net-hapas at three stocking densities in concrete pond was carried out. 4.68 5.25g mean individual weight fish were stocked at 25, 50 and 100 per m3. A 40% protein balanced diet was used as feed. The results of the study showed no statistical significant difference in growth among the three treatments. Food conversion ratios ranged in 1.60 to 1.82, and specific growth rates were between 3.80 and 4.16%/day. The result suggests that culture of C. gariepinus at a density of 50/m3 and production of 4.15kg/m3 in 84 days with production of 8.30kg/m3 in a growing season of 180 days is possible using the net-hapa systems enclosed in a concrete pond.

    Description: A feeding experiment was conducted to quantify the minimum dietary vitamin C requirement of Heterobranchus longifilis fingerlings and the minimal dietary inclusion levels that will meet these requirements after degradation from feed processing and storage. Fish were fed a basal diet with 42.5% crude protein for a conditioning period of 2 weeks. Following conditioning, fingerlings with initial mean weight, 2.3~c0.3 g were stocked as groups of 20 fingerlings into 30 litre tanks in a mini flowthrough experimental system and fed the basal diet and experimental diets supplemented with 0, 50, 100, 150, 200, or 250 mg of L-ascorbic acid kg-1 diet obtained from TUYIL PHARM. INDUSTRIES, lIorin, included into the basal diet by replacing part of the silica component and fed to triplicate groups for 20 weeks. Fish fed the control (0 mg vitamin C kg-1) diet exhibited deficiency signs including lordosis, caudal fin deformity, skin erosion and significantly suppressed weight gain and higher condition factor. Protein efficiency ratio and specific growth rate were significantly improved with increasing levels of vitamin C up to 200mg kg-1 diet. Tissue (liver, kidney, gills and muscle) ascorbate concentration generally reflected dietary inclusion levels with the signiticant lowest level occurring in the control groups. Vitamin C analysis after feed processing revealed 18 - 21% loss. The least mean squares error regression analysis of weight gain data on inclusion level of vitamin C revealed that the minimum dietary requirement of H. longifilis is 82.2~c0.2 mg vitamin C kg-1 diet which corresponds to 100 mg of vitamin C kg-1 diet based on data from this study.

    Description: Nigeria is a large fish consuming nation with a total consumption at more than 1.2 million tonnes, with fish imports making up about two thirds (700,000 t) of the fish supply. Although the contribution of fisheries to the Gross Domestic Product is only 3-4%, it occupies a very significant position in the primary sector providing employment for over a million people (FDF Statistics) and contributing about 50% of the animal protein intake of the population, particularly the resource poor. The estimated national demand for fish is estimated as high as 1.3 million metric tons with a wholesale value of more than $US 1 billion. Of this, the Federal Department of fisheries (FDF) estimated 511,000 tones are provided domestically or only about one third of demand, with an estimated per capita fish consumption ranging from 7.5-12 kg. With the current policy thrust towards fisheries development, there is excitement among stakeholders in private sector fish farming as shown by the expansion and renovation of existing farms and investments in few fish farms and hatcheries. This has brought the industry to a retail production value of N180 million. This development is not however without some challenges. Fish producers have rushed ahead with the production without support of a developed values chain. This gap is providing an entry point for interventions to greatly facilitate expansion of services in the value chain for this exciting industry. This paper therefore seeks to provide guidance on how to strategically focus aquaculture activities to capitalise on opportunities for increased employment and incomes.

    Description: Just like other animals and humans, fishes are prone to diseases and predation. Diseases can be caused by one and/or combination of any of the following agents e.g. bacteria, fungi, viruses and parasites. Diseases have become a primary constraint to aquacultural development, which may affect the achievement of a desired impact for rapid development of fish culture in Nigeria. Apart from causing mortalities, they also cause loss of production quality, reduced growth, reduced fecundity, loss due to control measures and loss due to social factors associated with the farmer. This review has discussed the diseases that are associated with integrated fish farming including livestock cum fish farming, poultry-cum fish farming, Waste water fish farming, rice-cum fish farming e.t.c. The control of diseases associated with integrated fish farming requires a multi-disciplinary approach including chemotherapy, sanitation, routine hygiene, quarantine, genetic selection and immunoprophylaxis. The treatment and prevention of fish diseases follow the same principles used in chemotherapy of higher animals.

    Description: Oreochromis niloticus was reared in 54 litre glass tanks being fed with 35% crude protein diets for 56 days. A basal diet consisting intact protein from groundnut cake and guinea com (4.56g lysine/100g protein) ,four graded levels of crystalline lysine was added to formulate diets consisting 6.87, 7.30, 7.41, 7.51 g lysine /100g protein and a reference diet of intact protein from groundnut cake, guinea com and fish meal having 5.37g lysine/100g protein was fed to six treatments in triplicate groups. The growth parameters shows there was no significant difference in the mean weight gain, specific growth rate, food conversion efficiency and protein efficiency ratio of fish fed varying levels of lysine. A maxima was obtained from the quadratic equation of food efficiency ratio against graded levels of lysine at 7.3g/100g protein which is the requirement. Carcass ash was higher with the initial fish while crude protein was highest with the the fish fed 7.3g lysine/l00g protein

    Description: Natural aquatic plants population can be healthy for any aquatic ecosystems as they serve as fish feed, play an important role in nutrient cycling, purify the water, control unwanted algal growth and support fauna including birds. Water hyacinths (Eichhornia crassipes) have proven to be a persistent and expensive aquatic weed problem. The review was carried out in the face of current global challenge (climate change) which threatens biodiversity conservation and sustainable use of natural resources so that water hyacinth could be viewed as an asset of multifarious benefits considering the revealed highlights rather than been labeled expensive nuisance. The simplest method of management of aquatic weeds is to harvest it and utilize it for cost effectiveness in production such preparation of fish and livestock feeds, bio-gas production, making of charcoal briquetting and waste water treatment for domestic and industrial use. The main problem of utilization and management of water hyacinth is its high cost of transportation to sites for utilization but, once this can be overcome as revealed in the review appropriate utilization techniques is recommended.

    Description: In recent times there has been an upsurge in the culture of Tilapia in Nigeria resulting in increased demand for the fingerlings which is hardly satisfied. This is due to increasing demand for table size tilapia as food fish and under-sized tilapia in the fish meal and fish canning industries in Nigeria. Collection of Tilapia guineensis fingerlings from the wild, to augment hatchery production, has been the practice and this is subject to environmental fluctuations. Multivariate regression and correlation analyses of accumulated data were used to investigate the effects of changes in water quality parameters on abundance of fingerlings of Tilapia guineensis in a brackishwater habitat in Lagos. Dissolved oxygen (DO), salinity and secchi transparency were found to be the most dominant factors affecting the abundance of Tilapia guineensis fingerlings in the Lagos lagoon. Peak period of abundance was closely associated with period of low salinity (0.50%o to 5.60%o), which coincided with the period of low transparency and low DO in the rainy season. The correlation analyses of Tilapia guineensis fingerlings with the water quality parameters yielded the following correlation coefficients (r)- 0.598; (salinity); -0.644 (transparency); -0.710 (DO); -0.566; (temperature) and 0.129 (pH). The abundance of Tilapia guineensis fingerlings in the Lagoon was ultimately defined by a suitable regression equation. This result is expected to optimize the collection of fingerlings of Tilapia guineensis from the wild and boost food fish security in Nigeria and elsewhere.

    Description: The concentration of heavy metals: Lead (Pb), Cadmium (Cd), Iron (Fe) and Zinc (Zn) in tissues of fin fish from a tidal fish farm in Calabar, South East Nigeria, was determined. The mean levels of heavy metals (~kgg-1) in gills, muscle tissues, liver and intestines of catfish were Pb: 2.39~c1.24; Cd: 0.87~c0.83; Fe: 3.96~c1.55; Zn: 8.15~c3.18. Mean levels in Tilapia were Pb: 0.035~c0.002; Cd: 0.61~c0.05; Fe: 1.09~c0.61; Zn: 2.17~c0.53. There was no significant difference (p〈0.05) in tissue concentrations of Pb and Cd whereas a significant difference (p〈0.05) was observed between Pb and Zn concentrations for both species of fish. Concentrations were also higher in liver, gills and muscle tissues than the intestines. Highest concentrations were observed in the liver and gills in both species. Generally, higher concentrations were observed in liver, gills and muscles of Catfish than in Tilapia. Concentrations of Pb and Fe in Catfish were significantly higher (p〈0.05) than the WHO limits, while Zn and Cd were lower. Tissue concentrations of all the metals in Tilapia were however, within the WHO recommended limits. The concentrations in all the fish tissues were significantly higher (p〈0.05) than in the surrounding water. The observed values in Catfish indicate environmental threat to the health of the fish and indeed the humans that consume them and therefore calls for environmental surveillance in the area

    Description: Spatial and temporal variations of physico-chemical variables of Onu-Iyi ?Ukwu stream were studied for 12 months from March 2005 to February 2006. Three sampling stations were established along the main stream channel from source to mouth. Spatial variation in physico-chemical parameters indicated that total alkalinity, total hardness, conductivity, and nitrate-nitrogen (NO3) recorded their highest values at the upper reaches (with values 14.0mg/l, 88.09mg/l, 17.00~kscmiscm, and 0.60mg/l respectively). Dissolved Oxygen (DO) and pH had their maximum values of 8.20mg/l and 6.94 at the middle reaches. Turbidity, biochemical oxygen demand (BOD), temperature and phosphate-phosphorus (PO4) increased steadily from source to mouth. The observed seasonal variation indicated that wet season values were higher for all the parameters except temperature, turbidity, phosphate-phosphorus (PO4) and total alkalinity although the values were not statistically significant at p〉0.05. The correlation coefficient (r) showed no significant relationships p〈0.05 between physico-chemical parameters except DO and BOD with correlation values of (0.75 and -0.54) respectively.

    Description: The physico-chemical parameters of Bosso Dam were analyzed weekly for a period of six (6) weeks from 29th October, 2009. In all, six (6) stations were identified within the dam. The physico-chemical parameters assessed were: temperature, dissolved oxygen, pH, alkalinity, hardness, conductivity and transparency. The results obtained from the analysis revealed slight variations in most parameters. There was no significant difference p〉0.05 in pH regardless of stations and weeks. But significant difference p〉0.05 were observed in dissolved oxygen, nitrate, temperature, conductivity, hardness, alkalinity, biological oxygen demand, transparency, in respect regard to stations. These variations could be due to influx of organic waste from surface run offs and inorganic waste deposited by man. The physico-chemical parameters observed, indicated that most of them fall with the recommended range or standard by the Federal Ministry of Environment

    Description: An experiment was carried out to find out the comparative effect of imported fish meal, blood meal and local fish waste based diets on the growth and survival of juvenile tilapia. (O. niloticus) in concrete tank. Four diets consisting of N.I.O.M.R. pelleted feed containing 40% CP, with imported fish meal, as the control and three others formulated with fresh, boiled cattle blood and local fish waste meal at 30% CP, were fed to juvenile tilapia with average initial weight of 55.24g in four treatments and four replicates in a completely randomized design. Result indicated final body weights of 100.83, 96.54, 98.4 and 86.82g and average body length of 18.47, 18.16, 18.4 and 18.14cm, for treatments 1 (control), 2 (fresh blood based diet), 3 (boiled blood based diet) and 4 (local fish waste meal based diet) respectively, with no significant difference between the treatments (P〉0.05). The same was also true for average daily weight gain of 0.41, 0.36, 0.31 and 0.28g. However, treatment 1 and 2 had better relative weight gain 93.69 and 80.21%, than 3 and 4 at 62.37 and 64.85% respectively, (P〈0.05). The survival was 100% in all treatments. Treatment 2 was more cost effective at N539.06/Kg fish, followed by 1 with N667.52. Treatments 3 and 4 had the highest at N698.20 and N718.60 per kg fish. The trial showed that tilapia feed processed with fresh cattle blood performed as well as imported fish meal, boiled blood and local fish waste and in addition was more cost effective.

Shell free Artemia and Live M. micrura combination was observed to have the lowest fry Percentage weight gain (428.30%),. specific growth rate(2.54), % survival rate (85.50), condition factor(24.39) and total body length(1.52cm). The highest total body length was observed in shell free Artemia although not significantly different (p〉0.05) from others. The implication of using cultured live M. micrura instead of shell free Artemia as starter diet for Heteroclarias hatchlings at the critical stage of development are discussed

    Description: The effect of substituting soybean meal with raw sunflower and sesame seed meal was evaluated using haematological indices of Clarias gariepinus fed the diets containing sunflower and sesame seed meal. Seven isonitrogeneous and isocaloric diets containing sunflower and sesame seed meal replacing soybean meal at a rate of 15, 30 and 45% were prepared. A diet without replacement of soybean meal served as control. The result of fish fed test diets showed significant (P〈0.05) difference over the fish fed control diet with respect to PCV and mean corpuscular volume (MCV). Fish fed control diet had the lowest Hb, PCV, WBC, RBC, MCV, MCHC, ESr. There was no significant difference (P〉0.05) in the fish fed control diet and test diets with respect to MCH, MCHC, ESr, Neutrophil, Monocytes, Eusinophils and Lymphocytes. Hence it can be concluded that the haemotological parameter of Clarias gariepinus is not significantly (P〉0.05) changed with increase dietary inclusion of raw sunflower and sesame seed meal.

    Description: Feeding trial was conducted in static water to assess the growth of Clarias gariepinus fingerlings fed different inclusion levels of Mucuna seed meal (MSM). Raw MSM was used at 10%, 20% and 30% inclusion levels and the performance of fish fed these diets was compared with the fish fed soybean-based diet which contained 40%protein. All diets were prepared to be isonitrogenous and isocaloric. A four by six factorial experiment with three replicates using ten fish each of average initial weight of 6.6g was carried out. Daily fish ration of five percent body weight was administered two times for twelve weeks. The specific growth rate (SGR) in diet 1 (control) was significantly (p〈0.05) higher than the other dietary groups and worsens as inclusion level increased similar trend was also observed in the food conversion ratio (FCR) and protein efficiency ratio (PER). The significantly lower growth performance of fish fed diets containing raw MSM might be due to the presence of anti-nutritional factors present raw MSM. The possibility of improving this trend through processing should be investigated.

    Description: Clarias gariepinus juveniles 6.35 ~C 0.22 g weight were fed five different commercial diets for 105 days to determine growth rates. Diets were hand distributed in triplicate groups of 30 fish once daily. The diets used were Coppens, Multifeed, Eurogold, Vittal and Ajanla feeds. At the end of the experiment, the final mean weight for Coppens, Multifeed and Eurogold were 181.54 ~c 0.63 g, 179.92 ~c 0.95 g and 139.92 ~c 0.26 g respectively, while final mean weight for Vital and Ajanla were 110.11 ~c 0.23 g and 119.03 ~c 0.35 g respectively. The statistical analysis of the results showed that there were significant differences (P〈0.05) in the mean final weights. Also there was no significant difference (P〉0.05) in the mean final weight between Coppens and Multifeed. The specific growth rates (SGR) were 3.19% day-1 3.18 % day-1 and 2.94% day-1 for Coppens Multifeed and Eurogold respectively and 2.71% day-1 and 2.78% day-1 respectively for Ajanla and Vital. There were significant differences (P〈0.05) in SGR among treatments and no significant difference (P〉0.05) between SGR of Coppens and Multifeed. Based on these findings, it was concluded that feed with macronutrient combinations of 45% CP, 12% crude fat, crude fiber, 1.5%, Ash 9.5% promoted better growth rates in C. gariepinus juveniles as compared with other combinations.

    Description: Clarias gariepinus (0.73 ~c 0.01g) and Heterobranchus longifilis fingerlings (0.67 ~c 0.01g) were fed five isonitrogenous diets of about 40% crude protein, with varying levels (0-100%) of palm grub meal for 12 weeks. At the end of the study, C. gariepinus and H. longifilis fingerlings fed 25% palm grub inclusion diet had the highest weight gain (5.30g and 4.05g respectively), relative (726.0% and 595.6%) and specific (1.09% and 1.00%) growth rates while those fed 100% palm grub inclusion diet showed least growth; weight gain (2.68g and 2.15g), relative (367.1% and 316.2%) and specific (0.80% and 0.45%) growth rates respectively. Food conversion and protein efficiency were also best in fingerlings fed 25% palm grub meal diet (0.70 and 1.35 for C. gariepinus; 0.75 and 1.35 for H. longifilis respectively) with decreasing efficiency as palm grub inclusion level increased in the diets. The differences in the growth and nutrient utilization of the fingerlings on the various diets were generally insignificant (p〉0.05) above 25% inclusion level of palm grub. The study showed that palm grub can be used to completely replace fish meal in mudcatfish diets. However, for optimal growth and nutrient utilization, 25% level of replacement of fish meal with palm grub meal is most adequate in C. gariepinus and H. longifilis fingerlings diets.

    Description: The study was carried out to investigate the lysine requirement and its effect on the body composition of Oreochromis niloticus fingerlings. Two hundred and seventy fingerling O. niloticus (9.01 -11.09g) were reared in 35L plastic troughs. Six diets were formulated, containing 35% crude protein. The diets were formulated with ingredients deficient of lysine (Groundnut cake -3.23g lysine/100g diet and guinea corn -1.9g lysine/100g diet) for O. niloticus having whole body content of 7.51g lysine/100g protein. The diets consist of a basal diet (Diet I, no added lysine), while the test diets (II, III, IV and V) had 4.56g, 6.87g, 7.30g, 7.41g lysine/100g protein respectively. The reference diet was made of Clupeids (mixture of Pellonula afzeliusi and Physalia pellucida), groundnut cake and guinea corn but no added lysine (5.37g lysine/100g protein). The fish were fed twice daily (0900 and 18.00hrs) at 3% body weight for 56 days. There was significant difference in the mean weight gain and food conversion efficiency (P〈0.05). The four levels of lysine resulted in quadratic responses (P〈0.05). Calculation using regression equations from the relationship between the specific growth rate, weight gain and lysine levels show that lysine requirement for fingerling was 7.12g/100g protein respectively. The requirement of O. niloticus for lysine is 7.12g lysine/100g protein.

    Description: Aquaculture is one of the fastest growing food production systems in the world, Nigeria inclusive with the bulk of its output currently being produced within developing countries and with expectations for aquaculture sustainable food security and poverty alleviation. However, poverty which is a social condition characterised by the inadequacy of access to basic human needs for the maintenance and socially acceptable minimum standards of living is still prevalent. One of the major obstacles to achieving the objectives of poverty reduction through aquaculture is the inadequate credit facilities to boost production. The study therefore, this study investigates the sources and uses of micro-credit in poverty alleviation among fish farmers in Osun state, Nigeria. A two stage random technique was used to select 137 respondents from the three Osun State Agricultural Development Programme (ADPs) zones. Structured questionnaire was used to collect data on demographic characteristics, Micro-credit sources and use, occupational, income and fish production data. Data was analysed using descriptive statistics, FGT and logit model. The result shows that both formal and informal micro-credit sources were used in the area studied with high interest rate militating against the adequate use of some of the micro-credit sources. Poverty alleviation through micro-credit use will increase efficiency through the use of modern effective and efficient technology leading to greater production. The policies aimed at making micro-credit readily available should be focused on to alleviate poverty among fish farmers

    Description: Over 200 hatcheries of fish exist in Nigeria with at least two hatcheries in each state of the federation but unfortunately over 50 percent are either non-functional or function far below their optimum production capacities. Also about 85 percent of the non-functional hatcheries belong to the government (-either federal, state, local government or institution). The associated problems with the non-functional hatcheries include: inadequate funding, poor maintenance of hatcheries facilities, high cost of feed inputs, in adequate infrastructure, differential growth and cannibalism in catfishes which result in poor fingerling harvest, low attitude and lack of commitment to government work. Privatization/ownership options are considered the best options for this paper and clues to solve the problems mentioned above through privatization are presented. Problems with privatization and private investment are also discussed. It was advised that in case the existing hatcheries are put in to full production, the national demand for fingerlings which is placed at 4.3 billion annually could be met with ease. Fingerlings production in the hatchery as the quickest revenue yielding aspect of fish farming (with high internal rate of returns and short pay back period) capable of attracting revenue within 2-3 mouths of a breeding exercise are emphasized.

    Description: The paper traced aquacultural development in Nigeria to the colonial period in 1950s with fish farming in tilapias during which more than 200 small scale subsistence level ponds were built with some growth continuing in the rural areas. There was a bloom in farming of catfishes in 2000. The interest shown by private fish farmers has been identified as a propelling factor for aquacultural development in Nigeria. The development of private fish hatcheries has been another factor leading to the growth of aquaculture. The paper noted that social capital and its development either directly or indirectly can be identified as contributing to the success of the sectors. The increasing profit from aquaculture has led to fish farmers increasing beyond 5000 tonnes in 2009. The paper highlighted the numerous advantages which led to the expansion of the industry in Nigerian villages.

    Description: The paper asserted that shellfish resources are poorly developed and utilized in West Africa. This was proved by the fact that in 2008 total marine shellfish capture production in West Africa was only 29,815 tonnes. The advantages of Nigeria in beefing up its production are highlighted. Some of these advantages are on extensive coast line which has not been affected by industrial pollution. The tropical climate is also an advantage for growing of cultured shellfish. The paper highlighted that to maximize the potential of shellfish Mari-culture development requires education, training, seed production technology, grow-out technology, processing and marketing. These requirements are discussed in details in the paper.

    Description: In Cambodia, fish provide a major source of animal protein for rural households. Capture fisheries have declined and aquaculture has been identified as playing an important role in food and nutritional security and rural income generation. In 2011, WorldFish, in partnership with the Stung Treng Fishery Administration Cantonment and the Culture and Environment Preservation Association, aimed at improving the uptake of small-scale aquaculture by communities with limited experience in fish culture in Stung Treng Province in northeast Cambodia. The system was given the name “WISH ponds,” derived from the combination of the words "water" and "fish" to reflect the integration of fish cultivation with water for storage and vegetable growing. It was targeted towards households with limited space to construct large aquaculture ponds, such as peri-urban households. The study indicated that WISH ponds can create an important learning platform for communities to address challenges associated with small-scale aquaculture development by using scientific data generated and owned by the participants. Results from this 2011 study provided important insights into the challenges and constraints for introducing small-scale aquaculture into rural households in Cambodia. In mid-2013, WorldFish won a Feed the Future Partnering for Innovation grant, funded by the United States Agency for International Development, to build upon its successful engagement with communities in northeast Cambodia where WISH ponds had already been introduced and investigate scaling this technology to establish more WISH ponds in these communities.

    Description: This working paper aims to synthesize and share learning from the experience of adapting and operationalizing the Research in Development(RinD) approach to agricultural research in the five hubs under the The CGIAR Research Program on Aquatic Agricultural Systems. It seeks to share learning about how the approach is working in context and to explore the outcomes it is achieving through initial implementation over 3 ½ years. This learning can inform continuation of agricultural research in the second phase of the CGIAR research programs and will be useful to others aiming to implement research programs that seek to equitably build capacity to innovate in complex social-ecological systems. Each of the chapters in this working paper have shown that RinD has produced a range of outcomes that were often unexpected and broader in scope than might result from other approaches to agricultural research. RinD also produces innovations, and there is evidence that it builds capacity to innovate.

    Description: Tilapia lake virus (TiLV) is an emerging infectious agent that has recently been identified in diseased tilapia on three continents. At the time of writing, scientific publications have reported TiLV in samples collected from Colombia, Ecuador, Egypt, Israel and Thailand. While the link between TiLV and disease outbreaks in Israel and Thailand are well documented, further investigations are being undertaken to determine the significance of TiLV in the other countries. Israel and Taiwan Province of China have made a notification of TiLV as an emerging disease to the World Organisation for Animal Health (OIE). Studies have shown that populations infected with TiLV show variable levels of morbidity and mortality. This report summarizes the currently available scientific information on TiLV, including clinical signs, diagnostics and epidemiology. While of no concern to human health, the consequences of infection with TiLV in tilapia populations may potentially result in socio economic losses and impacts on food security.

    Description: With the onset of Tilapia Lake Virus (TiLV) outbreaks in several Asian countries, WorldFish, in collaboration with Bangladesh’s Department of Fisheries, has developed a program to improve biosecurity in the tilapia industry throughout the country. As the first step, a training program has been designed and conducted to train a group of specialists called Master Trainers on improving tilapia hatchery biosecurity. This manual is a result of that program. The Master Trainers will use this manual for training tilapia hatchery technicians countrywide on how to improve biosecurity in hatcheries.

    Description: The production of Oreochromis niloticus (Family Cichlidae) was carried out at Kigera Reservoir using a total of 54 0.niloticus comprising of 34 males (62.96%) and 20 females (37.04%), with 57.41 % been sexually matured. This species bred throughout the period of study. It is a matertanal mouth brooder with females species carrying eggs, hatchlings and fries in their mouth. The sex ratio of O. niloticus was 1 :2. The maximum fecundity was 1152 eggs. The relative high fecundity recorded was an indication of suitability of studied areas for fish production. The environmental factors monitored showed that dissolved oxygen ranges from 3.7 to 5.4mg/l, rainfall ranges from 34.9 to 348.5mm, temperature was between 25.5 and 34.5~'C, pH value was between 7.4 and 7.5 while the rate of sunshine was between 23/4 and 61/2 hr. The spawning of this species in their natural or hatchery condition is therefore best achieved during the peak of raining season.

    Description: The physico-chemical and biological characteristics and nutrient concentration of Kigera Fish Farm ponds were monitored for two months to assess the water quality. The parameters measured were dissolved oxygen, temperature, hydrogen ion concentration, Secchi-disc transparency and zooplankton composition. Some fish species were identified in the course of study. Temperature ranged from 26 -30degreesC; dissolved oxygen ranged from 3mg/l-6.6mg/l, pH ranged 7.0 -7.2; while Secchi-disc transparency ranged from 0.19 - 0.25m. The three ponds were quite similar in these parameters. All the parameters that were investigated in this study are within the tolerable level for warm water fishes. Five different zooplankton species were identified at the Kigera Fish Farm, and were grouped according to their major categories namely: Copepods, Cyclopoids and Copepodite), Cladoceran (〈i〉Moina〈/i〉), and Rotifera (〈i〉Asplanchina〈/i〉). 〈i〉Branchionus〈/i〉 species in the Rotifers group dominated the zooplankton species in all the three ponds.

    Description: Honey comb was involved as floating additive in fish diets at 0, 4 and 8% levels in 30% crude protein Clarias gariepinus juveniles of mean weight 30.30~c0.05g for 56 days in aquaria each measuring 60 x 30 x 30cm. Within six weeks all stages of grain weevils Oritzaphillus mecartus were associated with the honey comb diets, while those with honey comb remained as kept. Feed and fish values were better in honey comb diets. The growth, food utilization indices; feed and fish values were significantly (P〈O.05) higher in honey comb diets. Bee keeping for income and honey comb usage in fish diets were suggested to fish farmers.

    Description: The United States Agency for International Development-Aquaculture for Income and Nutrition (USAID-AIN) project, implemented by WorldFish, emphasized technology development for improved fish strains, and capacity building in hatcheries and nurseries for wider dissemination and uptake among small- and medium-scale household and commercial producers. Improving nutritional benefits from household aquaculture investment was also an important activity of the project. Specifically, AIN aimed to increase aquaculture production by developing hatcheries and nurseries, disseminating improved fish and shrimp seed, enhancing farm management skills of smallholder farmers, promoting new technologies to expand commercial aquaculture, developing backward and forward market linkages, supporting policy reform and building capacity of the public and private sectors, which resulted in increased productivity and revenue for farmers. This report also highlights the major achievements of the AIN project between 2011 and 2016.
