    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: Effect of spices on the chemical properties of hot-smoked catfish (C.gariepinus) was examined. The experimental design was complete randomized design (CRD) with the treatments been the variously spiced hot-smoked catfish (garlic, ginger, garlic-ginger homogenate spiced and the control without spices). Proximate and mineral content analyses were carried out using standard experimental procedures. There exist significant differences (p〈0.05) in the percentage moisture and crude protein content with smoked catfish without spices having the highest moisture content with mean value 6.18 ~c 0.13 and 79.44 ~c 0.13 respectively which could be as a result of the increase in the fibre content of the spiced fish products which is a function of fibre content of the spices applied to the fish products. Similar trend was also observed for the lipid and ash contents the fish products. There exist significant differences (p〈0.05) in the mineral content preseent in the various fish products with the exception of magnesium. The products are rich in calcium and other minerals with garlic-ginger homogenate spiced product having the highest level of calcium (0.980 ~c 0.02).

    Description: Post harvest contamination can occur if drying of feed is delayed and when water is allowed to exceed critical values for mould to grow during storage. This study examined the aflatoxin levels in fish feeds surveyed in Abeokuta, Ogun State, Nigeria. Fifteen (15) fish farms were randomly selected for assessment of the aflatoxin levels in fish feeds in Abeokuta. After the estimation of the aflatoxin levels using Veratox quantitative aflatoxin test, the Aflatoxin concentrations in the samples ranged between 0-49 ppb with a mean value of 6.89 ppb. Results obtained from this study showed that aflatoxins were found to be associated with fish feeds in different fish farms in Abeokuta, but, a very high proportion of the feed samples were below the regulatory levels (maximum of 20 ppb) that may not be toxic to the health of the fish according to the regulatory levels for aflatoxins issued by the Food and Administration of the United States. Thus, feeds fed to the cultured fish species in farms in Abeokuta were fit for consumption, with very little or no threat of aflatoxicosis (a disease that can affect many species of fish, when feed contaminated with aflatoxin is consumed).

    Role of feed handling in fish farms in Abeokuta, Ogun State, Nigeria (2021)
    FISON | Minna (Nigeria)

    Description: This study examined fish health status in relation to fish feed handling. Twelve (12) fish farms were randomly selected for assessment of types of fish farms, sources, disease problems associated with fish feeds as well as mode of operation and age of farms in Abeokuta, Ogun State Nigeria. Structured questionnaires were administered for data collection. The fish farms surveyed were categorized into three (3) main groups: farms with less than five (5) fish rearing tanks as small scale production (16. 7%), farms with more than five but less than 10 fish rearing tanks as medium scale production (75%) and farms with above ten (10) fish rearing tanks as large scale production (8.3%). The operational methods were fingerlings production (25%), grow-out (table-size) production (25%) and those involved in the production of both fingerlings and table-size fish (50%). All the farms surveyed utilized compounded rations with only one farm combining compounded rations with natural food (artemia). All the farms experienced different levels of limitations in sourcing for feeds. The types of diseases identified on the farms were bacterial disease, parasitic disease as well as water pollution problem. As regards the duration of feed storage, feeds stored for three months and above suffered more disease problems with increase in water pollution level and presence of parasitic disease, while feeds stored for less than two (2) months experienced only bacterial disease. In controlling the highlighted diseases, farms with brood stock fish adopted only the effort of elimination of water (l00%), those involved in fingerlings used antibiotics and malachite green (50% and 100% respectively), those involved in the production of table-size fish used antibiotics (50%), while those involved in production of both fingerlings and table-size employed 100% water elimination.

    FISON | Lagos (Nigeria)

    Description: A study was carried out on the fatty-acid composition of Macrobrachium vollenhovenii (African river prawn) in Ogun estuary, Ogun State, Nigeria. Sexes and size groups were considered during the study. Fatty-acid analysis was done in triplicates and data obtained were analyzed using descriptive statistics, analysis of variance and Duncan's multiple range tests. Fatty acids analysed which included oleic acid, linoleic acid,' stearic acid, myristic acid, palmitic acid and lauric acid were classified into saturated and monounsaturated fatty acids. All values of saturated fatty acids were higher in female (29.64%) than in male (25.50%) p〈 0.05. So also the monounsaturated fatty acid also showed higher value in female (29.64%) than in male (25.50%). All fatty- acid values were higher in female M. vollenhovenii than in male. Meanwhile, myristic acid was highest in the two sexes and the combined sexes, (35.68% female), (33.14% male) and (34.74% combined sexes). The fatty-acid components were not influenced by the size of the fish. This study clearly indicated that the nutritive value of M. vollenhovenii is quite well comparable to the edible species of decapods already studied (shrimps, prawns and lobsters) and could be included in both human and livestock diets.

    Description: The Alawariwa beels located in the flood plains of the Ogun River, off Ibafo in Owode/Obafemi Local Government Area of Ogun State number 16 with an approximate total surface area of 28.0 hectares. The beels are conveniently exploited between January and April annually when the dry season and riverine contraction make this possible. The daily landing showed that the fish enclosure is truly a natural fisheries reserve as well as a medium of biodiversity. Fish catch per unit effort is reasonable especially for the more abundant fish species. The beel is sufficiently productive and worthy of the fishing efforts of the fishing efforts of eight fishers undertaking the daily assignment. Beel fishing is therefore economically advisable for fishers having access to such valuable communal or individual natural wetland resources
