Aquaculture is one of the fastest growing food production sectors to every household in Nigeria. Products from aquaculture such as fish food supply protein to household protein. However, biosafety of food products from aquaculture is now considered as public health concern in Nigeria. This is due to the nature and component of materials used as rearing facilities on the fish farm. Elimination of unwanted fishes and other predators is a common practice among fish farmers in Nigeria prior to stocking of desirable fish fingerlings. The use of synthetic pesticides to eliminate unwanted fishes and other predators in pond is persistent and could get into the food chain. Thus, the use of environmentally safe natural pesticides as an alternative is being embraced in aquaculture because they have a short time of toxicity disappearance and biodegradable. This will enhance the principles of sustainable aquaculture production and its management in Nigeria. In Southwestern Nigeria, there is little or no information on commercial production of Moringa oleifera for aquaculture purpose. There is the need for future development on Moringa production on commercial scale in Southwestern Nigeria and elsewhere in the tropics for sustainable aquaculture development. The paper therefore reviewed possible guide to Moringa oleifera production, methodology for its potential application in sustainable aquaculture development in Southwestern Nigeria. Possible prospects and challenges to encounter during commercial production were discussed.

The study evaluated the accessibility and problems associated with the use of information and communication technologies in rural areas of Ondo State. Total sampling was used to select 92 rural fish farmers from three riverine Local Governments in the state between February and April. Questionnaire was used in data collection. Data were analyzed by the use of frequency, percentage, mean and Chi-square test. It was found that radio (96.7%), television (84.4%) and mobile phone (95.7%) were most accessible ICTs to fish farmers of which radio is the most effective (62.0%). Problems associated with the use of ICTs were electric power supply (96.7%), lack of access to ICTs (62.0%) and inadequate information on ICTs (59.8%). There were significant relationship (P<0.05) between problems associated with the use and accessibility of ICTs by fish farmers. It is recommended that the government should allow a wide range of radio broadcast options by giving opportunities for private competition provision of radio content which will allow for development input from relevant agencies.

Fish farming has great potentials for ameliorating the problems of youths unemployed, poverty and nutritional deficiencies because it has been found to be economically rewarding and capable of providing vast employment, augmenting farmers' income and improving standards of living of the citizenry. The study assessed farmers' awareness and adoption of fish farming technologies in Obi-Akpor Local Government Area of Rivers State. A sample of 87 fish farmers was selected from the population of about 570 through multistage random sampling technique. Structured interview schedule was used to collect relevant research data. Data were analyzed with descriptive statistics (percentage and ranking). It was found that cat fish was cultured by more than 81% of the respondents. More than 72% of the farmers were aware of the eight fish farming technologies under study. More than 71% adopted aerator, flow through system, float fish feed and ova-prim but adoption of pituitary gland and re-circulatory system were at very low ebbs. High cost of feed, erratic power supply, inadequate capital and untimely or unavailability of production information were the major constraints to adoption of fish farming technologies. It was recommended that farmers continue to culture catfish which is hardy, easier to rear and tolerant to stressful conditions. Intervention programmes should be implemented to ensure that farmers adopt technologies whose adoptions were at low ebbs. The Government should subsidize the prices of fish feeds and other inputs while improving the perennial poor power supply.

Methods of improving the quality of fish seed supply to fish farmers in Benue State were studied. Data were obtained from one hundred and thirty three fish farmers' using multistage random sampling technique. Structured questionnaire was used to obtain information from the respondents; data obtained were analyzed using descriptive statistics and Chi square to test relationship between the variables. The result showed that 53.83% of the fish farmers source their fish seeds from the wild. Methods of improving the quality of fish seed supply through brood-stock management were culture method (97.10%), feeding (94.10%) and genetic composition (97.0%). The major constraints to the methods of improving the quality of fish seed supply were respondents' technical knowhow (99.2%), inconsistent government policy (99.20%), lack of government assistance (97.0%) and inadequate extension services (97.0%). The Chi square analysis showed significant relationship between brood stock management and methods of improving the quality of fish seed supply (p<0.05). Also, significant relationship existed between methods of improving the quality of fish seed supply and constraints, inadequate water supply, scarcity of feed, poor brood stock management and lack of government assistance. Government should encourage the fish seed production industry by providing infrastructures, formulation and effective enforcement of consistent policies and provision of credit facilities to fish farmers.

Efforts towards increase in fish production through artisanal fishery can be achieved by making needed inputs available. Fishing requirements of artisanal fishers in coastal communities of Ondo State, Nigeria were studied. Data were obtained from two hundred and sixteen artisans using multistage random sampling technique. Structured interview scheduled was used to obtain information from the respondents. Data were analyzed with the use of descriptive statistic such as frequency counts and percentage. Chi-square was used to test relationships between the variables. The results showed that 73.6% had fifteen years and above fishing experience and 58.8% had between twenty to thirty thousand monthly incomes. Majority (71.8%) used cast net while 80.10% required canoe and 30% 40 HP outboard engines for fishing. The chi-square analysis showed significant relationship between fishing input requirements of artisans and fishing experience for canoe (χ² = 0.00, p < 0.05), outboard engine (χ² = 0.00, p< 0.05) and netting material (χ² = 0.00). All the fishing input were significantly related to artisans monthly income (P<0.005). Based on the study, it is recommended that Government through the Federal Department of Fisheries should regulate and subsidize fishing inputs to improve the living standard of artisans.Key Words: Artisanal fishers, coastal communities, fishing experience, fishing input, monthly income.
