    Description: There are more occupational and health hazards in the Fishing Industry than in other occupational categories in the world. In Nigerian Industrial Fisheries, safety measures are regulated while little attention is given to safety standards in the artisanal fisheries. In West Africa, the coastal artisanal canoe fatality rates have been given in 1991-1994 to be 300 to 1,000 per 100,000 fishermen. Thus, the fatality rate in Nigerian artisanal fisheries, (coastal states) has been estimated to be 999 to 3,329 per 100,000 fishermen. The high rate is due to piracy, boundary disputes between fishing communities, unemployment, societal low value for human life and human labour. The paper discusses the various types of accidents associated with artisanal coastal fisheries and give recommendations. Fishermen have rights to safe working conditions in their working environment just as workers in offices and factories on land.

    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: 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.

    Description: Elongation (cm) and breaking-load (kgf) effects on artisanal Polyvinyl-Alcohol (PVA) synthetic twine of diameters 4mm, 6mm, 8mm and I0mm soaked in fresh (0.4ppt), brackish (25ppt) and marine (37ppt) waters for 112 days were investigated. Chemical (burning) test was carried out to identify the experimental white twine as PVA, among other six locally synthetic twines (Klust, 1973). A tensile-strength gauge machine (0-200kg) was used to test the mechanical strength properties of PVA twine diameters in dry (control) and wet states. Results indicated that elongation and breaking-load of the specimens were significantly (P〈0.05) influenced by R- Tex. Elongation and breaking-load were observed to be highest in dry twine 10mm with means of 20.75a ~c 1.05 and 140.00a ~c 5.37 respectively, higher in twine 10mm (with means of 20.40b ~c 3.50 and 131.75b ~c 5.l0 respectively) soaked in freshwater and lowest in twine 4mm (means of 1 4.83fg ~c 0.31 and 33.70h ~c 1.00 respectively) soaked in marine water. Twines of the same diameter (l0mm, 8mm, 6mm & 4mm) soaked in fresh water (0.7ppt) has highest significant (p〈0.05) elongation and breaking load than those soaked in brackish (0.25ppt) and marine water respectively. The thicker the PVA twine diameter, the higher the significant (p〈0.05) elongation and breaking load, which could lead to increased mesh sizes of fishing nets constructed from such twines. Fishermen are therefore encouraged to air-dry their fishing nets or gears when not in used to extend the shelf-life.
