    Description: Public health issues can he considered as those of direct importance to both producers and consumers of fish and include broader issues of food production, processing and delivery systems. As aquaculture assumes an expanding role in meeting consumer demands for fish and fishery products, it is natural that they meet safety and quality standards. Aquaculture is a growing industry in Nigeria and it has assumed commercial importance activity. This study was part of the project on epizootiological survey of pathogenic diseases of cultured fish species and is aimed at identifying ecto-parasite associated with cultured fish in Ogun State, Nigeria. The study which was carried out in 2012 covered fifty fish farm, spread across the three senatorial zones. Five pieces of fish were randomly picked from each farm surveyed. Participants observation and structured questionnaires were administered to fish farmers in order to gather information on source of fries, fish feeding and feed type, use of manure and its type, pond type, stocking density, pond hygiene, water source, frequency of changing water and history of diseases and mortalities of fish. Before the fish samples were collected, pond size and physicochemical water quality were assessed. Water test kits were used to measure parameters like iron, nitrate, alkalinity and ammonia. All the procedures for physicochemical water quality parameter analysis was done according to the manufacturer's instructions. Water pH was measured using a probe while dissolved oxygen and both water as well as air temperature were measured by using Hanna kit. All types of farms are included in the survey such as hatcheries, brood stock farms as well as grow out farms. The study revealed the spread of parasites across the senatorial zones. The most common encountered parasites were Trichodina sp, Gyrodactylus sp, Dactylogyrus sp and trematodes. The intensity of the parasites differed markedly.

    Description: Climate change has the potential to severely impact coastal and inland environments and ecosystems, and by extension fisheries and aquaculture. Coastal regions of the world are already experiencing flooding due to rise in sea level. In recent times, salinization of coastal areas due to flooding from storm surges and high tidal influence has been observed. Aquaculture is a fast growing agri-business venture in Nigeria presently and many coastal communities derive their livelihood from it. The culture of freshwater fish species that are very sensitive to high salinity may be threatened leading to mortality of stocked fish and loss of livelihood for coastal population. Consequently, there is urgent need for development and domestication of the Silver catfish, Chrysichthys nigrodigitatus that can tolerate higher salinity more than Mudcatfish (Clarias gariepinus). This will help mitigate the impact of salinization of coastal areas arising from sea water flooding on culture of fresh water fish species.

    Description: This study was conducted to evaluate the socio-economic analysis of small scale fish farmers in Lagos state fish farming estate in Ikorodu, Nigeria. The primary data were obtained from 60 respondents with structured interview guides and face to face interview, which were selected using simple random sampling techniques. The result revealed that most (88.3%) of the fish farmers are male while (31.40%) are in the active age distribution of 31-40 years, university education (63.0%) and 58.3% were married, 73.4% had a household size that ranged between 3 - 5 persons. Results of the descriptive analyses and tests of significance however showed that there was a significant relationship between socio-economic characteristics and constraint of fish farmers in the estate, there is also a significant relationship between income of fish farmers and constraints of the fish farm enterprise. Implications of these findings were critically-examined, and pertinent recommendations were proffered based on the salient findings in the study.

    Description: This study examined the demand analysis for fresh fish in Abeokuta metropolis of Ogun State, Nigeria. Data were collected with the aid of structured interview schedules and direct interview to elicit information from 150 fresh fish consumers randomly selected from within the locality of three major fresh fish markets (Olomore, Itoku, and Kuto). The data collected were analyzed using descriptive statistics and regression analysis which revealed that most of the fresh fish consumers (95.9%) were literates with mean household size of 5 persons. Also, 70% of the respondents are female out of which 71.3% are married, 52.8% were in the active age of 31-40 years old, and 70% are Yoruba speakers. Few (33.3%) of the high income earners spends the least income expenditure on fresh fish while 67.7% of the low income earners spends on frozen fish. It was evident from the study that the quantity of fish demanded increases as household size, income and age increases. The regression results shows that 36.8% of the total variation in the demand for fresh fish are variables while the remaining 63.2% were not explained by variables with R value of 0.368 according to the equation. Based on the findings, it was discovered that many people preferred fresh fish to frozen fish; efforts should be made to discourage importation of frozen fish and divert the huge amount spent on importation on expansion of aquaculture industry for the provision of more fresh fish for the consumers.

    Description: Traditional fish processing technologies vary widely in terms of equipment type, size and processing efficiency in Nigeria's coastal states. This study was carried out to identify fish processing technologies and evaluate the effectiveness, energy sources and efficiency of fish smoking equipment in use in the study area. Data were collected using structured questionnaire administered between January and March, 2011 in seven fishing villages along the coastline in the lbeju-Lekki LGA, Nigeria. Major fish species being processed were identified; and the profitability of the post harvest technologies adopted was evaluated. A total of five traditional fish processing equipment were observed; and included galvanized iron sheet supported by planks 51 (46.4%); drum oven 8 (7.2%); black clay oven 24 (21.8%); red clay oven 9 (8.1%); brick kiln 5 (4.2%) and government model kiln 4 (3.5%). Generally, energy sources were fuel wood and charcoal for traditional fish processing equipment; and electricity for the government model kiln. Majority of traditional fish processors were peasant women; and three types of processing technologies were observed, including air drying (1.0%), hot smoking 169.1%); and salting and smoking (29.9%). The capacity of kilns and ovens observed ranged from 20 to 50kg daily with a price range of Nl0,000 to N50,000. Factors considered before replacement of smoking equipment by the processors were equipment ruggedness, cost and production capacity. Women's involvement in traditional fish processing was 95%; and major fish species in the value chain included Ethmalosa fimbriata, Caranx senegallus, Sardinella maderensis,Drepane africana, Cynoglossus monodis, Pseudotolithus megalensis, P. typus, Arius latiscutatus and A. mercatoris. It was observed that products of traditional fish processing industry were readily acceptable to consumers and commanded marginal market prices with optimal economic benefits to processors.

    Description: The study was conducted to assess the feeds and feeding techniques adopted in fish farming in the six extension blocks of Ijebu-Ode zone of the Ogun State Agricultural Development Programme, South Western Nigeria. The areas covered are Ala, Ago-Iwoye, Isonyin, Ijebu-Igbo, Ijebu-Ife and Ibi-Ade. Primary data were obtained from ninety fish farmers with well structed interview guides while combination of purposive and convenience sampling procedure was used in selecting the fish farmers. The result obtained showed that majority (34%) of the respondent fell within the economic active age distribution of 40-49 years, male (87%) married (90%:Christian 73.3%), tertiary education (47.7%), farming experience (54.4%), membership of cooperative society (63.3%),household size of above five (55.6%), annual income of above N51,000 (94.4%) and 34.4% of the respondents sourced their finance from personal saving. Most of the fish farmers adopted use of concrete tanks, intensive and semi-intensive culture system, culture Clarias and Heterobranchus species, produced about two tons per culture circle of six months. Majority (61.1%) of the respondents combine use of supplementary feed because of readily available desired feed.Recommendations are availability of credit and subsidies facilities, accessibility feed supplies, farmers’ cooperative, enabling government policies and farmers training and extension service provision.

    Description: The role of water in fish production could not be overemphasized. This is because water is required for the total functioning of fishes. This study therefore examined the relationship/effect of rainfall pattern on fish production. Secondary data were collected on mean annual rainfall and total annual fish output for the period of 10 years (2000-2009). The study showed that high rainfall was recorded in the year 2001 which marked the lowest fish production year due to floods effect on fish enclosures. These therefore implies that fish farmers should be encouraged to construct ponds with protective measures such as screens, dykes, freeboards, etc. which prevents total loss of stocks during heavy rainfall.
