    Beschreibung: This is the Investigation of rising nitrate concentrations in groundwater in the Eden Valley, Cumbria report produced by the Environment Agency in 2003. This report focuses on groundwater nitrate concentrations in the Eden Valley. Most boreholes in the Eden Valley had nitrate concentrations less than 20 mg/l but a significant number had higher concentrations, some exceeding the EC maximum admissible concentration for drinking water of 50 mg/l. The main objectives of this report were to investigate the causes of rising nitrate concentrations in groundwater in the Permo-Triassic sandstone aquifers of the Eden Valley area and provide sufficient understanding of the groundwater and surface water flow system, including the sources of the nitrate contamination and the processes controlling nitrate movement, so that possible management options for reversing this trend can be considered.

    Beschreibung: This is a technical report of a hydrogeological assessment by the Environment Agency, an assessment to inform the Stage 3 review of Consents under the Habitats Directive for Wybunbury Moss, a National Nature Reserve and Special Area of Conservation in Cheshire. In the Stage 2 Review of Consents, one groundwater licence could not be clearly assessed as having no significant impact and so was taken forward to Stage 3. Further work has been carried out to refine the understanding of groundwater flow and the extent of the actual groundwater catchment of Wybunbury Moss, including three drilled boreholes, the monitoring of groundwater levels in the boreholes by data-loggers for more than 18 months and the sampling and analysis of the groundwater from the boreholes. Results of this further work are shown in Appendixes. From this work, a geological cross-section and Conceptual Model has been produced, and a map showing the revised understanding of the groundwater catchment of Wybunbury Moss. It also includes in Appendix I, the Stage 2 Review of Consents previously made.

    Beschreibung: This report is the fourth collation of salmon and migratory trout catch statistics for England and Wales produced by the Environment Agency. For the years 1989-94 these statistics were published by the National Rivers Authority (NRA) and for the years 1983-88 by the Ministry of Agriculture, Fisheries and Food, Directorate of Fisheries Research, in its Data Report series. This report is designed to be a reference document of declared salmonid catches in England and Wales. Salmon stock assessment data including provisional catches, counter run estimates and some juvenile data are now published in an annual assessment for the International Council for the Exploitation of the Seas (ICES). The second report in this series was published jointly by the Environment Agency and the Centre for Environment, Fisheries & Aquatic Science (CEFAS) in April 1998 (Anon 1999).

    Beschreibung: This is the River Eden RHS and geomorphology evaluation: Final report October 2001 produced by the Environment Agency North West in 2001. This report analysed the River Habitat Survey (RHS) and geomorphology data to evaluate the level of habitat quality and the geomorphological characteristics of the River Eden and sub-catchments. RHS data and geomorphological assessment data was collected within the study areas by CEH and Fluvial Environmental Services Ltd. The River Eden and its sub-catchments are being considered as a Special Area for Conservation (SAC) due to the presence of habitat types and species, which are rare or threatened within Europe. The purpose of the project is to provide an overview of the state of the catchment in terms of river habitats and geomorphological processes in order to aid the derivation of sound management for this proposed SAC.The aim of this report was to determine the state of the environment within the Eden and sub-catchments and identify the main pressures on the system in order to derive sound management options.

    Beschreibung: This is the Report of 1996 survey of Trout Beck with particular reference to spawning gravel quality and invertebrates as a food source for salmonids produced by the Environment Agency North West. Whilst the main River Derwent is quite a high profile salmon fishery, Trout Beck is not a significant fishery in its own right, but serves to maintain the genetic integrity of the wild populations of trout and salmon in the catchment by providing a unique habitat. This survey addressed the invertebrate food availability, and additionally looked at the substrate to try to determine whether the bed type might actually be unsuitable for spawning, especially in view of the previously mentioned silt inputs.

    Beschreibung: This is the River Lynher Salmon Action Plan Final document produced by the Environment Agency in 1999. This final Salmon Action Plan (SAP) for the River Lynher catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Lynher salmon stock. The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The River Lynher salmon stock has suffered two periods of spawning target failure within the past ten years. This assessment can only be estimated and in this case is likely to be dependent on river flow and the availability of salmon to the rods as only rod catch is used in the compliance assessment.

The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. This Action Plan aims to promote long term collaboration and co-operation between the Agency and other interested parties to effectively and efficiently manage the stock of salmon on the River Tavy.

    Beschreibung: This is the River Axe Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Axe Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. This document is part of a national initiative to produce action plans for the management of all the main salmon rivers of England and Wales by 2003. The aim of this plan is (i) to assess the status of the salmon stocks and fisheries of the River Axe - including the use of Conservation Limits as part of this process, (ii) to identify factors which may be limiting stock and fishery performance and (iii) to propose remedial measures address these factors. The salmon stock of the River Axe was apparently in a healthy state in the 1950s, supporting net and rod fisheries with average annual catches of around 100 and 50 fish respectively. Catches declined through the 1970s and 1980s to the extent where no salmon were recorded in the late 1980s and early 1990s. This decline was probably due largely to the effects of agricultural pollution, which virtually extinguished the salmon stock of the River Axe. Water quality has subsequently improved, but has deteriorated again in recent years.

The report pays attention on the external consultation of the River Lyn Salmon Action Plan (SAP). This approach to salmon management within the England and Wales introduces the concept of river-specific Conservation Limits as a method of assessing the status of the salmon stock. The River Lyn Salmon Action Plan follows the format of those completed for the Rivers Exe, Axe, Avon & Erme, Teign, Torridge, Taw and Dart. It is the last of eight action plans that have been produced for salmon rivers within Devon Area. The River Lyn Salmon Action Plan contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The Lyn salmon stock is judged to be meeting its Conservation Limit. However, this assessment is uncertain as it is based on an estimate of rod exploitation rate, which in itself is also uncertain.

    Beschreibung: This is the Rivers Avon & Erme Salmon Action Plan Consultation document produced by the Environment Agency in 2003. This document is part of a national initiative to produce action plans for the management of all the main salmon rivers of England and Wales by 2003. The aim of this plan is (i) to assess the status of the salmon stocks and fisheries of the rivers Avon and Erme - including the use of Conservation Limits as part of this process, (ii) to identify factors which may limiting stock and fishery performance and (iii) to propose remedial measures address these factors. The report pays attention on the external consultation of the Rivers Avon & Erme Salmon Action Plan (SAP). While the stocks of both rivers have exceeded their respective conservation limits occasionally in individual years, only the Erme has achieved a period of statistical compliance since 1993. It is possible that this situation is largely normal, due to the steep nature of the rivers, obstructions to migration and dependence on suitable flow conditions occurring at the right time of year. The decline of the spring-running component of the stocks has left the populations dependent on autumn flows for the success of the late running component. Actions required to improve compliance with Conservation Limits are proposed and prioritised. The urgent actions relate to the need to improve the consistency with which adequate numbers of salmon reach and utilise fully all the accessible areas of the river systems. This document is intended to be dynamic, with opportunities for review occurring at regular intervals. For example, as the science of fisheries management improves, particularly in the setting of Conservation Limits, so the targets may be altered to reflect any improved methodology.

    Beschreibung: This is the River Plym Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Plym catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Lynher salmon stock. These issues and actions follow on from the detailed analysis of the catchment, which is presented in the River Plym SAP Consultation document.The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The main objective of the River Plym SAP therefore, is to maintain, improve and develop the River Plym salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support. The River Plym has failed to pass its conservation limit since 1996, and the consultees felt very strongly that there were three major factors limiting the salmon stock of the River Plym.

The report pays attention on the external consultation of the River Exe Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Exe SAP follows the format of those completed for the Rivers Teign, Torridge, Taw and Dart. It is the fifth of eight action plans that will be produced for salmon rivers within Devon Area. The River Exe SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The Exe salmon stock is judged to be meeting its Conservation Limit. However, this assessment is uncertain as it is based on an estimate of rod exploitation rate, which in itself is also uncertain. At present there is no means of accurately assessing the River Exe salmon run. In common with many other rivers, estimation of stock using catch statistics and rod exploitation rate is the model used, when direct assessment is not possible. The installation of a fish counter on the lower river, or the use of other direct counting methods, would help to provide a direct assessment of the annual run of salmon into the river. This would improve our ability to estimate the spawning escapement and hence assess compliance with the Conservation Limit.

    Beschreibung: This is the River Teign Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Teign Salmon Action Plan (SAP). This approach to salmon management within the England and Wales introduces the concept of river-specific Conservation Limits as a method of assessing the status of the salmon stock. The River Teign Salmon Action Plan follows the format of those completed for the Rivers Torridge, Taw and Dart. It is the fourth of eight action plans that will be produced for salmon rivers within the Devon Area Fisheries, Recreation and Biodiversity Team. The River Teign SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The Teign salmon stock is currently failing to meet its conservation limit. This failure is largely attributed to the reduction in the survival rate during the marine phase of the salmon life cycle. This is likely to constrain stocks to lower levels than have existed historically. Still further catch controls may contribute to a reduction in exploitation rates and allow stocks to recover to meet their conservation limit. Other important actions include the continuation of habitat improvement works which aim to maximise spawning habitat utilisation, spawning success, and juvenile survival and production.

This final Salmon Action Plan (SAP) for the River Torridge catchment has been produced after consideration of feedback from external consultation. The SAP provides a list of the issues and actions which were agreed for a five-year programme to maintain and improve the River Torridge salmon stock. Some of these actions have already been delivered before finalising the SAP, but others have yet to be addressed. An attempt has been made to estimate the cost of the actions, identify possible sources of funding and the timescale under which they will be dealt with. The Torridge salmon stock has declined dramatically since the 1960s and is currently failing to meet the spawning target. The decline in the spring fish component has accounted largely for the overall decrease in stocks. The reasons for the decline are not fully understood, but the spring fish problem is recognised as a national issue. The rate of survival over the marine phase has reduced in recent years for both the grilse and multi-sea winter (MSW) components. This is undoubtedly a contributory factor, which may now constrain stocks to lower levels than have existed historically. Agricultural pollution is recognised as one of the main factors limiting freshwater production. This SAP aims to promote long term collaboration between the Agency and other interested parties in managing the River Torridge salmon stock and fisheries.

    Beschreibung: This is the Coleopteran Fauna of ERS on the river Dane, Cheshire: a survey report produced by the Environment Agency in 2003. A comprehensive survey of the Exposed Riverine Sediment (ERS) on the River Dane, Cheshire was undertaken between mid-April and mid-June 2003. 6 locations were selected and subsequently examined to determine the importance of the constituent invertebrate fauna. Appropriate sampling techniques (i.e. pitfall trapping, hand searching and excavations) were directed towards the target group (Coleoptera). All adults from the chosen taxa were identified to species level. The relative value of the fauna was assessed using species richness, conservation status, fidelity score and a site quality index.

    Beschreibung: This is the Visual survey ERS Dane, Weaver & Bollin Catchments produced by the Environment Agency in 2005. Visual surveys of the River Dane downstream of the confluence with the Swettenham Brook, the River Weaver, and the River Bollin catchment in the EA Northwest South area of England were undertaken between 3rd and 9th February 2005 with the aim of identifying the spatial distribution and relative quality of exposed Riverine sediments (ERS). The potential value of these ERS in terms of likely habitat quality for ERS invertebrate communities was determined by recording a suite of appropriate environmental variables. Following an initial cartographical analysis of reaches likely to contain ERS, tens of kilometres of riverbank were inspected and 67 areas of ERS were selected for detailed visual survey. Site characteristics ranged widely both between and within catchments, with habitat quality ranging from poor to very high.

    Beschreibung: This is the River Fowey Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Fowey Salmon Action Plan (SAP). The River Fowey SAP follows the format of those completed for the Rivers Tamar, Lynher, Tavy and Camel. It is the 5th of 7 action plans that will be produced for salmon rivers managed by the Cornwall Area Fisheries, Recreation and Biodiversity Team. This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Fowey SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. Notably, there are historic workings for copper and china clay and two significant potable supply reservoirs (Siblyback and Colliford) which have been constructed within the catchment during the past 35 years. The whole of the Fowey catchment is set at the highest water quality grading of RE1 and this standard is met in all reaches of the River Fowey and its tributaries.

This final Salmon Action Plan (SAP) for the River Camel catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Camel salmon stock. The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. This Action Plan aims to promote long term collaboration and co-operation between the Agency and other interested parties to effectively and efficiently manage the stock of salmon on the River Camel.

    Beschreibung: This is the Proposed Environmental Quality Standards (EQS) for Phenol in Water prepared for the National Rivers Authority, and published by the Environment Agency in 1995. The report reviews the properties and uses of phenol, its fate, behaviour and reported concentrations in the environment and critically assesses the available data on its toxicity and bioaccumulation. The information is used to derive EQSs for the protection of fresh and saltwater life and for the abstraction of water to potable supply. Phenol is widely used as a chemical intermediate and the main sources for phenol in the environment are of anthropogenic origin. Phenol may also be formed during natural decomposition of organic material. The persistence of phenol in the aquatic environment is low with biodegradation being the main degradation process (half-lives of hours to days). Phenol is moderately toxic to aquatic organisms and its potential to bioaccumulate in aquatic organisms is low.

    Beschreibung: This is the Stillwaters monitoring programme summary results 2000 from the Environment Agency. In May 1997, a Stillwaters meeting was held to discuss the way forward in stillwaters monitoring. It decided upon the establishment of a three year rolling programme, in which three stillwaters would be monitored three times a year, every third year. During 2000, stillwaters monitored for the fourth year of the Stillwaters Monitoring Programme were Hatch Mere, Marbury Big Mere, Comber Mere, Tabley Mere, Tatton Mere and Melchett Mere. Algal, zooplankton and water chemical samples were taken on all meres. Surveys of Tabley Mere and Comber Mere continued on from last year when water quality concerns were highlighted. Continuous monitoring in Oak Mere, including water level data continued in 2000. Fish surveys were carried out in Tatton Mere and Comber Mere. Tabley Mere survey was abandoned due to the awkward bathymetry of the mere. No invertebrate samples were taken in 2000 due to lack of resources.

    Beschreibung: This is the Proposed Environmental Quality Standards (EQS) for Nonylphenol in Water produced by the Environment Agency in 1997. The report reviews the properties and uses of Nonylphenol, its fate, behaviour and reported concentrations in the environment, and critically assesses available data on its toxicity and bioaccumulation. The information is used to derive EQSs for the protection of fresh and saltwater life as well as for water abstracted to potable supply.Nonylphenol (NP) is used extensively in the production of other substances such as non-ionic ethoxylate surfactants. It is through the incomplete anaerobic biodegradation of these surfactants that most nonylphenol reaches the aquatic environment in effluents, e.g. from sewage treatment works and certain manufacturing operations. It was explicitly stated by the Environment Agency that the EQS was to be derived for NP and not Nonylphenol ethoxylates. However, since NP is unlikely to be present in the aquatic environment in the absence of other nonylphenol ethoxylate (NPE) degradation by-products, the toxicity, fate and behaviour of some of these (i.e. nonylphenol mono- and diethoxylates (NP1EO and NP2EO), mono- and di-nonylphenoxy carboxylic acids (NP1EC and NP2EC) have also been considered in this report. In the aquatic environment and during sewage treatment, NPEs are rapidly degraded to NP under aerobic conditions. NP may then be either fully mineralised or may be adsorbed to sediments. Since NP cannot be biodegraded under anaerobic conditions it can accumulate in sediments to high concentrations.

    Beschreibung: Between July 2005 and February 2008, ten Catch Assessment Surveys (CASs) were conducted at 54 pre-selected fish landing sites in the Ugandan part of Lake Victoria comprising approximately 10% of all landing sites in each of the 11 districts sharing the lake. The CASs were conducted following regionally harmonised Standard Operating Procedures (SOPs). This report covers the CAS conducted in February 2008 and puts into context the trends generated by results of the previous surveys. The catch rates of Nile perch in gillnetting boats with motor/sail, reduced from 26.9 kg boat-1 day-1 in August 2007 to 22.8 kg boat-1 day-1 in February 2008. Whereas the catch rates of paddle Sesse boats remained more or less the same as in August 2007. The Nile perch catch rates of the long line fishery of the boats using motor/sail was similar, 35 and 36 kg boat-1 day-1 in August 2007 and February 2008 respectively but the catch rates of paddle Sesse boats using long lines showed some more increase from 19 to 22 kg boat (-1) day (-1). In the tilapia fishery, the catch rates of the parachute boats using gillnets showed further decrease in a row from 12.6 kg boat-1 day-1 in December 2006, 11.6 kg boat-1 day-1 in March 2007, 11.2 kg boat-1 day-1 in August 2007 and 10.0 kg boat-1 day-1 in February 2008. The overall impact of reduced catch rates in the predominant effort groups, e.g. gillnetting boats using motor/sail in the Nile perch fishery and Parachute boats using gillnets in the tilapia fishery overshadowed the increases in less dominant effort groups and resulted in the lowest monthly catch estimates recorded in the surveys conducted since 2005. Whereas there was a clear downward trend in the Nile perch catch rates of boats using gillnets, which corroborates with the information of declining stocks from the recent Acoustics surveys, the catch rates in the long line fishery remained stable and even somewhat increasing in the last four surveys. The factors that maintain high catches against reduction of fish biomass in the long line fishery and their effects on sustainability of the Nile perch fishery should be investigated further. The Mukene fishery, characterised by large fluctuations in the catch rates did not show much change in the last two surveys in August 2007 and February 2008 and the annual catch estimates showed an overall increase of 7% from 2005 to 2007. The Mukene fishery in the Ugandan waters of Lake Victoria remained a near shore fishery in which paddle Sesse boats using small seines or scoop nets were the dominant craft.

    Beschreibung: This is the Impact Assessment of ionising Radiation on Wildlife document produced by the Environment Agency in 2001. This report describes the behaviour and transport of radionuclides in the environment, considers the impact of ionising radiation on wildlife, and makes recommendations on an approach for the Impact assessment of ionising radiation on wildlife for England and Wales. The assessment approach focuses on three ecosystems representative of those considered potentially most at risk from the impact of authorised radioactive discharges, namely a coastal grassland (terrestrial ecosystem); estuarine and freshwater ecosystems. The likely scale of the impact on wildlife is also assessed in light of a preliminary analysis based on this assessment approach. The report demonstrates the behaviour and transfer of radionuclides in a number of different ecosystem types. Particular emphasis is placed on exposure pathways in those ecosystems most likely to be impacted by the authorised discharges of radioactivity within England and Wales. The use of biomarker techniques is reviewed in the report, and their application to the study of exposure to multiple contaminants is discussed.

    Beschreibung: This is the report on Habitats Directive, the Review of Consents Stage 1 and 2 by the Environment Agency of the Rochdale Canal cSAC.The Habitats Directive has the main aim to promote the maintenance of biodiversity by defining a common framework for the conservation of wild plants and animals and habitats of community interest. The Directive establishes a European ecological network known as "Natura 2000". The network comprises Special Areas of Conservation (SAC) and Special Protection Areas (SPA). In the section on Stage 1 or Screening Process of the Habitat Directive, it is identified the likely impacts upon the Rochdale Canal of a project, plan or activities, either alone or in combination with other projects, plans or activities, and considers whether these impacts are likely to be significant. In the section on Stage 2 or Appropiate Assessment of the Habitat Directive, it is considered the impact on the integrity of the Rochdale Canal of the projects, plans or activities, either alone or in combination with other projects, plans or activities, with respect to the site’s structure and function and its conservation objectives. Additionally, where these are adverse impacts, an assessment of the potential mitigation of those impacts. The criteria used in this report to identify relevant projects, plans or activities and their impacts are water quality discharge consents, waste management licences, abstraction licences, Integration Pollution Control (IPC) and Integrated Pollution Prevention Control (IPPC) permits. Proformas, hydrogeological and GIS maps are included in the review.

    Beschreibung: This is the River habitat survey and geomorphological evaluation of the Glaze Brook Catchment report produced by the Environmental Research and Consultancy of the University of Liverpool in 2002. The major aims of the project were to provide baseline information on river habitats in the Glaze catchment using standard River Habitat Survey (RHS) methods (sampling 25% of the catchment length) and, through the geomorphological audit, to assess the distribution and intensity of geomorphological processes, notably sediment transfer, sources and sinks. This information was then used to develop informed management recommendations. The Glaze catchment is a heavily modified watercourse of generally poor habitat quality. The most important factors contributing to the low quality of the sites are poor bank and channel features; low diversity/absence of channel vegetation; paucity of bankside trees and, to a lesser extent, a lack of channel substrate diversity. The high degree of modification relates principally to extensively resectioned banks and channels plus extensive culverting in the urban parts of the catchment.

    Beschreibung: This is the River Axe Salmon Action Plan Final document produced by the Environment Agency in 2004. The River Axe Salmon Action Plan (SAP) has been produced after consideration of feedback from public consultation. The final plan provides a list of the agreed issues and actions for the next five years to maintain and improve the salmon stock of the River Axe. Efforts have been made to identify possible sources of funding, partners and timescales. It indicates how the plan will be managed, including the process for reviewing stock status, issues, actions and progress. Low marine survival is currently a major factor limiting salmon stocks throughout the United Kingdom. However, on the River Axe the freshwater environment is still the main factor limiting the recovery of the salmon stock. Most of the adults returning to the Axe at present are probably derived from hatchery reared smolts, although there has been some natural reproduction in recent years. Juvenile populations in the Yarty indicate that this is a tributary where salmon have started to re-establish a self-sustaining population. Actions to improve the quality of the freshwater environment, both in terms of water quality and sedimentation, are seen as the top priorities, and are required to allow the Axe to support a self-sustaining salmon population.

    Beschreibung: This is the River Dart Salmon Action Plan Consultation document produced by the Environment Agency in 2003. The report pays attention on the external consultation of the River Dart Salmon Action Plan (SAP). This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The north of the River Dart catchment is included in the Dartmoor candidate Special Area of Conservation (cSAC), designated under the Council EC Directive 92/43/EEC, the “Habitats Directive”. One of the conservation objectives for the cSAC is to maintain the habitat for Atlantic Salmon, Salmo Salar in favourable condition. The River Dart is an important salmon, sea trout and brown trout fishery with no significant coarse fishery. However, eels are ubiquitous throughout the catchment and are lightly exploited. The River Dart SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery.

This final Salmon Action Plan (SAP) for the River Lyn catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Lyn salmon stock. The actions presented within this Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. An attempt has been made to cost these actions, identify possible sources of funding and to provide a timescale for action. This SAP aims also to promote long term collaboration between the Agency and other interested parties in managing the River Lyn salmon stock and fisheries.

    Beschreibung: This is the River Fowey Salmon Action Plan Final document produced by the Environment Agency in 2003. This final Salmon Action Plan (SAP) for the River Fowey catchment has been produced after consideration of feedback from external consultation. It provides a list of the agreed issues and actions for the next five years to maintain and improve the River Fowey salmon stock. The actions presented within this final Salmon Action Plan clarify the important issues and factors currently limiting the salmon stock on the river. The resolution of these issues should ensure that a sustainable salmon population will be maintained for future generations. The main objective of the Fowey SAP therefore, is to maintain, improve and develop the Fowey salmon stocks to a sustainable level that, on the basis of historic catch records, the catchment can clearly support. Although the Fowey is passing its conservation limit, the consultees felt very strongly that there were two major factors limiting the salmon stock of the River Fowey- the overgrazing of Bodmin Moor and the use of the catchment for water supply by South West Water.

    Beschreibung: This is the River Lynher Salmon Action Plan Consultation document produced by the Environment Agency in 1998. The report pays attention on the external consultation of the River Lynher Salmon Action Plan (SAP). The River Lynher SAP follows that for the River Tamar and is the second of seven action plans that will be produced for salmon rivers managed by the Cornwall area fisheries department. This strategy represents an entirely new approach to salmon management within the UK and introduces the concept of river-specific salmon spawning targets as a salmon management tool. The River Lynher SAP contains a description of the river catchment and highlights particular features that are relevant to the salmon population and the associated fishery. The analysis of recent and historical catches of salmon on the River Lynher from both the rod and net fisheries indicated the fishery's reliance upon post 1 June salmon. Historically, annual salmon catches (both rod and net) on the River Lynher have been found to consist of a much higher proportion of pre 1 June (spring) salmon. Evidence is provided that illustrates the extent of the decline within this stock component since the early 1980s.

    Beschreibung: Multimesh, multidepth gillnet fleets are useful in assessing fish stock abundance, size distribution and depth distribution. Using data collected on net mesh selectivity for Nile perch, Lates niloticus (L.), in the Kenyan waters of Lake Victoria, suitable mesh sizes for gillnet fleets for use in the Lake Victoria Fisheries Research Project were determined. The modal selection length for Nile perch in the mesh sized used in the earlier experiment were determined, as was the size range vulnerable to capture.Initial trials suggest 60% of the Nile perch swim within 5 m of the bottom. Setting and hauling of the nets is simple and quick, allowing the nets to be used at the same time as other sampling programmes.

    Beschreibung: Co-management is typically known to be a resource management system that shares managerial responsibility between the state and other stakeholders of a resource. In the case of Lake Victoria, one would expect the state to be represented by the fisheries departments of Kenya, Uganda and Tanzania, while stakeholder groups may comprise fishing communities, fish processing factories and municipalities.Taking that into account, the survey's objectives were defined as:(a) To identify the difficulties and impracticalities inherent in implementing state-based regulations via a "top-down" management strategy.(b) To assess the prevalence of community-based institutions that either seek to regulate the fishery or have the potential to be used to regulate it.(c) To identify ways in which community-based regulatory and monitory systems may be established, and how these will fare over time.(d) To identify roles for national Fisheries Departments, industrial fish processors and other stakeholders.(e) To develop well-founded policy suggestions for the establishment of a co-management framework to manage the fisheries of Lake Victoria.

    Beschreibung: Three Lake Victoria rivers were sampled to assess fish abundance and distribution in preparation for assessment of catches from the river systems. Preliminary fish abundance data indicate that fishing potential upstream is negligible but that important commercial species are present in the downstream floodplain areas. Three catfish species were recorded in the Nzoia river system that have not been found previously in the Kenyan sector of the Lake Victoria system, together with possibly two undescribed Barbus species.

    Beschreibung: The number and size composition of gillnets, fishing grounds, and the quantity and composition of fish catches were related to the size of fishing boat. The overall number of gillnets per boat increased from 20.9 + or - 2.3 nets in 5-6 m long boats to 88.6 + or - 11.8 nets in 11-12 m long boats. The proportion of large mesh sizes, + or more than 127 mm, also increased from 40% in 5-6 m long boats to 100% in boats longer than 10 m. Fish catches are related to the size of boat and this should be considered when formulating management guidelines of the lake's fishery. Promotion of large fishing boats 8 m or longer and restriction on the number and/or mesh size of gillnets of smaller boats could increase ecological and socio-economic benefits.

    Beschreibung: A total of 457 hauls were taken during experimental bottom trawl surveys in the Uganda sector of Lake Victoria between November 1997 and June 1999 to estimate composition, distribution and abundance of the major fish species in waters 4-60 m deep. Fifteen fish groups were caught with Nile perch, Lates niloticus (L.), constituting 94% by weight. Haplochromines and L. niloticus occurred in all areas sampled, while Nile tilapia, Oreochromis niloticus (L.) and other tilapiines were restricted to waters 30 m deep or less. The mean trawl catch rate in the zone where artisanal fishermen operate (i.e. in waters less deep than 30 m was 165 kg hr, of which 93.6% comprised L. niloticus. Species diversity and relative abundance decreased with increasing water depth.

    Beschreibung: Catch and effort assessment surveys have been used to assess trends in fish landings in Kenyan waters of Lake Victoria since 1976. Landings reached a maximum of 200000 t annually in 1989-1991 as Nile perch, Lates niloticus (L.), catches increased due to an expansion in stock size and increased fishing effort. CPUE peaked at 180 kg boat day-1 in 1989 and decreased thereafter with increasing effort. By 1998 total Nile perch catches were half those at the beginning of the decade despite increased effort. Catches of Rastrineobola argentea (Pellegrin) have levelled off despite increased effort.

    Beschreibung: Bottom trawl surveys were conducted in Kenyan waters of Lake Victoria during the period September 1997 and March 1999. The means of fish biomass for the two most important species: Lates niloticus (L.) and Oreochromis niloticus (L.) were estimated at 61.5 kg ha and 4.5 kg ha respectively. There were few L. niloticus greater than 80 cm TL and O. niloticus greater than 50 cm TL, though these species attain maximum sizes of 205 cm and 65 cm respectively. Oreochromis niloticus was mostly found shallower than 5 m though some specimens were encountered deeper than 10 m, suggesting that the species has extended its ecological range. Very low catches were obtained from areas under water hyacinth cover. Water in such areas was turbid with oxygen levels below the critical 3.0 mg L.

    Beschreibung: Catch trends from Fisheries Department reports from the last eleven years (1985-1995) were analyzed. These showed a shift in the fishery from a cichlid-based system to one dominated by Nile perch and tilapias. In recent years, catches have declined from a peak in the early 1990s. Catch per unit effort appears to have remained stable except for a drop in 1995, however, this is considered dubious because the effort showed a doubling in that year. Limitations of the fisheries data collection system for the Tanzanian sector of Lake Victoria are highlighted and discussed.

    Beschreibung: Four fleets of hanging coefficients 0.2, 0.4, 0.6 and 0.8 were used to determine size selectivity and selection factors of Nile perch populations. There was a linear relationship between mesh size and modal length of capture. Positively skewed length frequency distributions were found for smaller mesh sizes with entanglement becoming more prominent in mesh sizes above 101 mm. Nets of 114 to 141 mm stretched mesh yielded higher economic returns than small meshes, the catch consisting of few largefish.

    Beschreibung: Caridina nilotica (Roux) (Decapoda: Atyidae) was investigated over a period of four months in three zones of Lake Victoria. Abundances were estimated by vertical net sampling. The importance of C. nilotica in the diet of the three commercial fish species was investigated. Caridina nilotica is a primary food for Lates niloticus (L.), Oreochromis niloticus (L.) and Rastrineobola argentea (Pellegrin). A quantitative study of C. nilotica in the fishing area indicated high biomass which can support the Lake Victoria fisheries.

    Beschreibung: Recent surveys have indicated an increase in haplochromine biomass recorded from the bottom trawl and in the beam trawl. The haplochromines recovering in the offshore waters belong to three species in the zooplanktivorous trophic group: Yssichromis laparogramma (Greenwood and Gee), Yssichromis fusiformis (Greenwood and Gee) and Astatotilapia lacrimosa (Boulenger). In this paper, the species composition and relative abundance of the zooplanktivorous haplochromines recorded from the bottom and frame trawl surveys in the various parts of the Ugandan waters of Lake Victoria are discussed.

    Beschreibung: The reproduction of Nile tilapia, Oreochromis niloticus (L.), in the Nyanza Gulf of Lake Victoria was studied from June 1998 to May 1999. Length at maturity ranged from 28-30 cm TL for females and from 32-34 cm TL for males. Males were more abundant in all length classes longer than 36 cm TL. Relative condition factor was above unity, except in August, October and May for males, and October for females. Gonadosomatic index (GSI) was low during the post spawning period (July to October) and high during the protracted breeding period (December-June).

    Beschreibung: Oreochrimis niloticus (L.) was introduced to Lake victoria in the 1950s. It remained relatively uncommon in catches until 1965, when the numbers began to increase dramatically. It is now the third most important commercial fish species after the Nile perch, Lates niloticus (L.) and Rastrineobola argentea (Pellegrin). Oreochromis niloticus is considered a herbivore, feeding mostly on algae and plant material. The diet now appears to be more diversified , with insects, fish, algae and plant materials all being important food items. Fish smaller than 5 cm TL have a diverse diet but there is a decline in the importance of zooplankton, the preferred food item of small fish, as fish get larger. The shift in diet could be due to changes which have occurred in the lake. Water hyacinth, Eichhornia crassipes (Mart.) Solms, which harbours numerous insects in its root balls, now has extensively coverage over the lake. The native fish species which preyed on these insects (e.g. haplochromines) have largely been eliminated and O. niloticus could be filling niches previously occupied by these cichlids and non cichlid fishes. The change in diet could also be related to food availability and abundance where the fish is feeding on the most readily available food items.

    Beschreibung: The zooplankton and macrobenthic communities of Lake Victoria were sampled by lift net and Ponar grab, respectively. The zooplankton comprised copepods and cladocerans, rotifers and aquatic insect larvae. Most taxa exhibited wide distribution in the lake, with the exception of rotifers which were rare in deep offshore waters. The main components in the macro-benthos were chaoborid and chironomid larvae and molluscs. Caridina nilotica (Roux) and other groups were rare in the samples. Zooplankton density ranged from 100000 or more to 4 million ind. m2 and increased from the shallow inshore to deep offshore waters. Numerical dominance of cyclopoids and nauplius larvae was a common feature at all stations sampled. Most macrobenthic taxa were also widely distributed, although chaoborid and chironomid larvae were rare in the samples. Rastrineobola argentea (Pellegrin) and larval Lates niloticus (L.) ate mainly cyclopoid copepods, while cichlids showed a strong preference for adult insects. High ecological stability of the cyclopoids, and the zooplankton community in general, despite radical ecosystem changes in recent years, coupled with what appears to be high predation pressure, offers good prospects for the pelagic fishery in the lake.

    Beschreibung: Size at first maturity, breeding periods and condition factor were determined for the small pelagic cyprinid Rastrineobola argentea (Pellegrin) in the Jinja waters of Lake Victoria in 1996-1997. Females showed a reduced size at maturity compared to ten years earlier when exploitation of the species was minimal. The males, however, have changed little. Although the species breeds throughout the year, two breeding peaks were observed during the drier months of August and December-January. Minimal breeding was observed in the rainy months of April-May and October-November. Fish from the open water station at Bugaia showed a higher proportion of breeding individuals than those from inshore areas. The mean monthly condition factor of fish from Napoleon Gulf confirmed breeding peaks obtained from examination of gonad development.

    Beschreibung: In a tagging experiment carried out in the Kenyan waters of Lake Victoria, an annual growth increment of 29 cm yr was obtained for Lates niloticus (L.). Growth parameters obtained using the von Bertalanffy model on the growth curve fitted by eye were L (inf.) = 122 cm yr and k = 0.26 yr. Data for other species tagged were inadequate to obtain meaningful results.

    Beschreibung: The Lake Victoria fish fauna was dominated by cichlids before the establishment of the exotic species Oreochromis niloticus (L.) and Latus niloticus (L.). With the alterations in the ecology of Lake Victoria, changes may be expected to occur in the population dynamics of the fish species. In two zones of Lake Victoria, the size structure, distribution and abundance, condition factors, length-weight relationship and sex ratios of O. niloticus were determined. Larger fish were found in zone II than in zone III, where very few larger fish were recorded. More O. niloticus were caught in zone III, especially in Itome Bay, than in zone II but catch by weight was greater in zone II. More males than females were encountered in both zones. Oreochromis niloticus had similar condition factors in both zones.

    Beschreibung: The zooplankton community of the littoral zone of Nyanza Gulf, Lake Victoria, was studied between June 1998 and June 1999 to identify and quantify various zooplankton groups, and investigate the interactions that occur between them and the littoral fish through the food chain. Zooplankton samples were collected from five stations using a 83 micro-m mesh size plankton net hauled vertically through the water column. Fish samples were obtained by beach seine, except at Gingra (May 1999), where trawl samples were used. Gut/stomach analysis was carried out on the three major commercial species, Lates niloticus (L.), Oreochromis niloticus (L.) and Rastrineobola argentea (Pellegrin).

    Beschreibung: Ihale is a large landing site lying approximately 65 km. from Mwanza along the main Mwanza-Musoma highway. Ihale Beach was selected as a potential candidate for the 3-beaches study because of its proximity to Mwanza, and hence suitability for frequent monitoring; and because it is served by a road accessible during the rainy seasons. As with the first training Participatory Rural Appraisal (PRA) on Kiumba Beach on Kenya's Rusinga Island, the objectives with this PRA were as follows: (a) To identify and understand Ihale's community-based organizations and institutions which have a role in the lake's fishery. (b) To consider the key issues which arise from this study for the involvement of communities and community-based organizations and/or institutions such as those at Ihale Beach, in the co-management of Lake Victoria's fishery.

    Beschreibung: This paper comprises part of the so-called "3-beaches Survey" of the LVFRP. In Tanzania, this study has developed to examine two landing sites (Mwasonge and Ihale), and to chart the progress of the newly established Beach Management Units (BMU) at each beach, comparing one BMU against the other. The over-arching objective of this survey was to develop an understanding of the context in which Mwasonge's fishery exists. The study does so by examining the community's history, culture and beliefs, various other socio-cultural factors, their resources, society and economy, wealth and the community's perceptions of wealth. Importantly, the survey examines the community's institutions and its perceptions of fishing rules and changes within the fishery. All of these facets of community life are examined with the use of participatory Rural Appraisal tools, and the images that the study generated are reproduced herein.

    Beschreibung: The present work is now concentrated mainly on the Tilapia fishery. As a result of past experience it is easier to direct efforts in a way likely to give useful results. Work on the Tilapia is now beyond the purely exploratory stage and these fishing experiments are being carried but in areas which are known to contain large numbers of Tilapia. Nets of different mesh size are being used in order to catch all stages of these fish. These nets are being fished at the surface and at the bottom, close to the shore and further out. The data collected should provide more precise information regarding the periodic migration, both vertical and horizontal, of these fish, a better understanding of their life history and breeding habits, and indicate' the potential possibilities of this fishery. These data should explain the variation in numbers of fish caught by Africans during different months of the year; they should also make it possible to determine more exactly the best type of net for use in this particular fishery.

    Beschreibung: This survey of the fisheries of Lake Rukwa, Tanganyika, describes results obtained during 1963-1964, and includes comparative material given by previous workers, in particular surveys conducted in 1936 by Ricardo and, in 1946 by Swynnerton. Data is given on the general hydrology of the Lake including chemical analyses, seasonal and annual fluctuations of volume. Cyclical variations of lake level occur every 20/30 years and the level now reaching a new maximum is expected to fall again during the next decade. The record of fish species from the Rukwa basin is enlarged by 3 genera: Polypterus, Protopterus and Chiloglanis; a summary of the biology and commercial exploitation of 20 species of fish is given. An historical account of the fish production from the lake and its subsequent marketing concludes that in 1963/64 some 5,328 tons of dried fish products are marketed annually; between 10-6;10 of this trade is directed towards the Rhodesias and the remainder is absorbed within Tanganyika. The state of the indigenous fishing enterprise is discussed, and for the improvement of the industry recommendations are given that the marketing of fish products should be immediately investigated and encouraged both abroad and within, Tanganyika. Further suggestions include the improvement of water-transport on the lake, the development of improved fishing-craft, fishing-methods, processing methods and further investigation of the biology of the fish-fauna.

    Beschreibung: In a previous report (Gee and Gilbert 1968) an attempt was made toestimate stock densities in the Entebbe area ,of Lake Victoria based oncatch figures obtained in EAFFRO No.1 trawl fitted with a 1" codendand towed at an estimated1.7.knots (probably an underestimate). Theresults were rather discouraging in that the figures obtained for stockdensities were definitely very low. It was felt that the major weaknessof the operations was the trawl net but as it was the only net availableand neither of the authors were expert on the design and constructionof more suitable nets, this particular net had to be used.

    Beschreibung: Fisheries continue to be important in the national economy, especially as anexport commodity. Fish exports increased from 15,876 tonnes valued at 34.4million US$ in 2000 to 28,153 tonnes valued at 79.0 million US$ in 2001.Consequently information for sustainable exploitation and management of fishstocks is a priority. In order to fulfill this requirement, FIRRI has beenimplementing two research projects. The first project focuses on sustaining andincreasing capture fisheries production through management of fish stocks,biodiversity and environment of aquatic systems. The second project focuses onincreasing fish production through improved fry production and pondmanagement and feeding of cultured species.

    Beschreibung: About 18% of Uganda’s surface area is covered with water from which about300,000 metric tonnes of fish are produced. Fish are currently the second mostimportant export commodity generating approximately US$100 million annually. Fish provides 50% of protein diet for the 20 million people translating into per capita consumption of 12 kg. Close to the production system, this figure rises to 50 – 100 kg. It is estimated that fishery-related activities employ at least one million people countrywide (i.e. 5% of the population).Fish exports to regional markets are worth at least US $ 20 million annually. Fishflesh contains an anticholesterol which assists in reducing heart diseases. Somefishes are of medicinal value e.g. haplochromines (Nkejje) are used to treat measles. Most of the fish in Uganda is got from lakes Victoria, Kyoga, Albert and Albert Nile, Edward and George production systems as well as from the 160 minor lakes and rivers and the associated wetland systems. Capture fisheries based in these systems contribute up to 99% of the fish production in Uganda but aquaculture is also picking up. The fishing industry employs up to one million Ugandans

    Beschreibung: The purpose of this output was to use the results of the baseline and participatory diagnostics analysis to develop alternative innovations for agricultural production, natural resource management and food security.The farming systems in the project areas were analysed to identify the innovations that communities had been using for agricultural production, natural resource management and food security. The innovative strategies were examined for their contribution to sustainable agriculture, food security and natural resource management. Comparative analysis of the agricultural productivity, food security and natural resource management in the different areas where the innovations have been put in place was undertaken.The best practices would be identified, which should be scaled-up, modified orsustained. The willingness and perceptions of the farmers to adopt the innovations would then be assessed.

    Beschreibung: Two species of the genus Tilapia occur naturally in Lake Victoria. Of these the most abundant and therefore the most important economically, is T. esculenta GRAHAM, and it is, for these reasons that more information is available concerning this species than the related T. variabilis BOULENGER. Thus LOWE (MCCONNELL) (1956) who was the first to make a serious study of the Tilapia species of the lake since the pioneering survey of GRAHAM (1929), dealt in considerable detail with T. esculenta but treated T. variabilis much less fully. Later studies (GARROD 1959) have also been concentrated on T. esculenta. Because of a relaxation in certain areas' of net-size regulations (discussed below) T. variabilis has recently assumed greater economic importance than was the case when restrictions were imposed, and this had called for further study of its general biology and the possible effects of commercial exploitation. The following account represents a preliminary contribution to the information required, and deals almost entirely with observations made in the northern waters of the lake and particularly in the vicinity of Jinja (Uganda).

    Beschreibung: The study is prompted by the poverty that persisted among the fishing communities of lake victoria at time of considerable cash inflow into the fisheries development of fish processing industry. There has been need for understanding of the poverty and what strategies would be most appreciate for it's reduction.This study has attempted to respond to the needby identifying the nature and distribution of the poverty within the fisheries lake victoria,Uganda, the factor responsible for itand the options for poverty reduction intervention. The study examined the global and regional perspectives of poverty and wealth distribution, noting that wide disparities existed between the developed and the developing world and also between the developing countries themselves. A historical review of development policies and strategies revealed that while successive strategies were able to contribute to growth, their achievement towards poverty alleviation were less than satisfactory, hence the need forcontinually developing new strategies.A background to Uganda’s society and economy is provided, examining the demographic, political, environmental and economic conditions of the country. Uganda’s developmentstrategies are reviewed, highlighting the role of the Poverty Eradication Action Plan, Uganda’s main strategy for implementing the policy of poverty reduction and wealthdistribution. At the agricultural sector level, the Plan for the Modernisation of Agriculture has been formulated, followed by the National Fisheries Policy, aimed at providing a policy framework for the management and development of the fisheries.An appropriate definition of poverty was formulated, considered relevant to the situation ofLake Victoria. The dimensions of poverty included inadequate basic necessities, low education and health achievements, a sense of insecurity and exposure to risk. The research methodology was enhanced by the examination of the Lélé Model of the Poverty–Environmental Degradation problem, the World Bank Model of Poverty Causation and thesubsequent Lake Victoria Model developed in this study. It has provided a plan for the research, the consideration of criteria and a data collection plan. The data collectioninstruments included secondary data search, key informant interviews and a sample survey based on a structured questionnaire.The study identified all the four dimensions of poverty in the fisheries, provided poverty profiles with respect to the different activities, groups of people and regions in the fisheries, based on consumption poverty. Among the people identified to be in poverty were the fishing labourers, fishers of Oreochromis niloticus and those operating with non-powered boats. In the post-harvest fisheries, large proportions of processors involved in salting and sun-drying, market stall and bicycle traders were in the poverty category. The ethnic groups most affected included the Samia, Basoga and Bakenye while the Districts of Jinja, Bugiri and Busia had the highest proportions of fishers in the poverty category. With respect to the other dimensions of poverty, the study showed that educational achievement was low within the fishing communities. The health status was poor, due mainly to the prevalence of malaria, diarrhoea, bilharzia and HIV/AIDS. There was a sense of insecurity within certain sections of the fishing community, due to leadership weaknesses within the local as well as the Government institutions. Some community members operated in a state of risk because they were vulnerable to episodes of income, health and education. The causes of poverty in fisheries included weaknesses within the institutional and social environment, limitations in the technology available to the poor, resource degradation and unfavourable economic factors. The recommendations of the study for poverty reduction included strengthening of policies, developing links, improving capacities and increasing resources, to be applied at the levels of Central Government, Local Government and of the community. In view of the achievements of the methodology used on this study, involving reference to the models, it is recommended that future research should build upon this model approach, as it will continue to produce results, especially when attempting to forecast changes relating to interventions.

    Beschreibung: Fish is currently one of the two most important agricultural export commodities from Uganda with factory-processed fish exported mainly to Europe, South East Asia and the Middle East worth at least USD 100 m annually. Regional exports are probably of similar significance. All recorded fish exports rely heavily (95%) on factory-processed Nile perch with the Nile tilapia increasingly entering the export market chain. Regional fish exports are more diversified in terms of species and include Nile tilapia, Nile perch, "mukene", Tiger fish and "Angara", the last two fished from Lake Albert. Regional fish destinations include Kenya, Tanzania, Rwanda, Sudan, DR Congo and some parts of Central Africa. Internal consumption relies on subsistence to semi-commercial fishes for a variety and species dominated by Nile tilapia

    Beschreibung: The field survey was undertaken by NaFIRRI technical staff. The terms of reference for the survey were to make an assessment of the lake for possible cage fish farming. The survey was undertaken on the 26 August 2010 by a team composed of the several. The lake supports small subsistence fishing activities by the local communities livingaround it. Information from the local community indicates that the fish species/typesoccurring in the lake include the Ngege, Nile perch, the African catfish and the lung fish.The fishing crafts in operation are largely Dug-out and Bao Tatu canoes and the main fishing gears are nylon and monofilament gillnets, hooks and beach seines.

    Beschreibung: The status of fish stocks in a water body at any one time is a function of several factors affecting the quantity of fish in that water body. These include:a) Total number (abundance) and biomass (weight) present,b) Growth (size and age),c) Recruitment (the quantity offish entering the fishery) including reproduction,d) Mortality which is caused by fishing or natural causes.Other indirect factors of major importance to the status of the stocks include productionfactors (water quality and availability of natural food for fish), the life history parameters ofthe different species making up the stocks (e.g. sex ratios, condition of the fish, reproductivepotential (i.e. fecundity) etc). Changes in fish stocks do occur when any of the above listedfactors directly influence aspects of growth, reproduction and mortality and therefore,numbers and standing stock (biomass).

    Beschreibung: This report presents findings of the CAS conducted in the Ugandan waters of Lake Victoria in May 2011. The results of the previous eleven CASs conducted under the IFMP of the LVFO programme in July, August, September and November 2005; in March, August and December 2006; in March and August 2007; in February and December 2008; and March 2010 are included to show the emerging trends. The report also presents annual catch estimates for the Ugandan part of the lake from 2005 to 2011.Through these CASs, information is building up to show the emerging picture of fish production in the Ugandan waters of the lake. Similar surveys are conducted in the Kenyan and Tanzanian parts of the lake, which provide the lake wide perspective of fisheries production but this time not simultaneously as under the LVFO effort due to different sources and timing of funding. These data can now be utilised together with other Resource and Socio-economic Monitoring survey data for a stock assessment of the lake to provide a firm basis for planning and management of the fisheries resources.

    Beschreibung: Lake Albert and Albert Nile are a major source of fisheries resources sustaining the riparian communities in Uganda and the Democratic Republic of Congo (DRC). Like all shared bodies of Uganda Lake Albert and Albert Nile fisheries are faced with immense exploitation pressure one time described as the tragedy of the commons. In Uganda, the lake is shared by five riparian districts namely: Buliisa, Bundibugyo, Hoima, Kibaale and Nebbi. The lake covers a total estimated surface area of 5,270 square kilometers with approximately 60% within Ugandan waters. It is located in the western part of the great rift-valley at an altitude of 618 m above Sea level. The central parts of the lake are characterized by steep escarpments whereas the northern and southern parts lie in a plain of the rift valley. The plains are gently sloping, resulting in shallow swampy inshore waters in many places. The major inflowing rivers are the Semliki and Kafu in the south, and the Victoria Nile at the northern tip. The lake has a diverse fish fauna with a gradient of multi-species fisheries in different parts of the lake.The overall objective of the Frame Survey was to provide information on the facilities and services at landing sites and the composition, magnitude and distribution of fishing effort to guide development and management of the fisheries resources of Lake Albert and Albert Nile.The specific objectives were to provide information on:a) The number of fish landing sites;b) The facilities available at the fish landing sites to service the sector including accessibility;c) The service providers especially fisheries staff at fish landing sites;d) The number of fishers;e) The number and types of fishing crafts and their mode of propulsion;f) The number, types and sizes of fishing gears used on the lake and their mode of operation.

    Beschreibung: A Catch Assessment Surveys (CAS) with the overall objective of generating information on the fish production and commercial value of the fisheries of Lake Albert and Albert Nile system was implemented by the National Fisheries Resources Research Institute (NAFIRRI) in collaboration with the Department of Fisheries Resources (DFR), Local Government staff (FOs) and BMU members at selected landing sites on Lake Albert (12 landing sites) and Albert Nile (26 landing sites) in July 2012.A total 622 and 313 boat days on Lake Albert and Albert Nile respectively were sampled for a period of 9 days. Results indicate an annual landing of 151,600 and 5,900 tonnes (t) of fish with an estimated beach value of 122.5 and 14 Billion (UShs) from Lake Albert and Albert Nile respectively. Over 80% of the catch from Lake Albert comprised the small pelagic species; Neobola bredoi (Muziri) and Brycinus nurse (Ragoogi) followed by Nile perch (6%). However, due to low market value of the small fishes and the high prices attached to Nile perch for industrial processing and export market, the contribution of the latter to beach value rose to 34% of the total. The contribution of the light fishery based on small pelagic species (B. nurse and N. bredoi) are insignificant on Albert Nile. Even if the small pelagic species may be present in the river system, a light fishery based on these two is yet to be developed. Proportionally, Albert Nile still remain a multispecies fishery with over 20 fish species harvested commercially. Interestingly, the Albert Nile fishery still remains primitive with simple crafts and gears (mainly dugout canoes, traps, and gillnets). This could suggest that the more developed the system becomes the higher the level of transformation in its fisheries leading to simplification, characterized by reduction in multispecies nature and dominance of few species.Illegal gears especially undersized gillnet of mesh size less than 4 inches were the most dominant in the Lake Albert and Albert Nile fisheries. They captured large quantities of immature fish particularly when used to target Nile perch, Bagrus, Nile tilapia, and large Barbus spp. Their impact when used to target the smaller species (Ragoogi, Angara & Ngasia) is yet to be evaluated. A specific study to analyze selectivity and impacts of these nets is a recommended. However, the dominance of 1.5” mesh sizes especially on Albert Nile to target Angara, Ngassia and Barbus, is definitely destructive to their fisheries and should be checked forthwith. In addition, there is an emerging fishing method locally referred to as “Salsio or Luzira” whereby fishers stay on the lake from 3 days up to 2 weeks without returning to the landing site. They carry with them food and salt for processing the catches on the lake, and in the case of Albert Nile on make shift shelters on islands and in the game park. They normally use gillnets of 3-3½ inch mesh size and caught mainly Nile perch & Bagrus (Pethi & Munama). On return they land several tons of fish. Most of these Catches are not captured in the estimates presented in our analyses since we target daily fishing boats. The possible impacts of this fishing method should be studied and appropriate action recommended.

    Beschreibung: Throughout the year the Fisheries Departments of Tanzania and Uganda continued to forward to EAFFRO data on the commercial fisheries of the lake. Regular records of commercial fishing activity In Kenya waters have not been received, appropriate information has been made available on request from the Chief Fisheries Officer. None of the research staff at EAFFRO have been assigned to a detailed survey of the statistica1 data available, although severa1 research officers have taken the opportunity of analysing the data appropriate to their own research programmes. As recorded in the last Annual Report, an important feature of the UNDP Lake Victoria Fisheries Research Project will be to undertake the relevant statistical surveys essential to the proper.

    Beschreibung: The methods of estimating codend selectivity for alternatehauls are briefly described and applied to Bagrus docmac (forskahl) data from Lake Victoria. Certain inconsistencies are noted and it is postulated that they may be due to differential escapement of larger Bagrus docmacthrough the trawl meshes when the different codends were fitted. The calculated 50% selection lengths yielded a fair regression on measured weigh give a fork length selection factor of 2.33, consistent with data from the smallest codend mesh size used. The implications of the findings are briefly discussed in relation to the proposed Haplochromis trawl fishery 1971.

    Beschreibung: Besides the formal publications held in the library (books, annual reports. Journals and reprints) a considerable quantity of unpublished Information on subjects relevant to freshwater fisheries in East Africa is held on various departmental files, etc.in Jinja. This material is extremely valuable: firstly because it is usually of immediate reference to current research work at EAFFRO, and secondly because it usually exists only as original material: no other copies are available elsewhere.
