    Description: Comparative study on the microbial load and proximate composition of fresh lean fish Labeo cubie and fresh fatty fish Synodontis membranaceus with their smoked products were carried out. The colony count of different parts was carried out on all the samples and the results show the highest microbial load on the gut of both the fresh lean fish and the fresh fatty fish. The smoked dried lean fish and the smoked dry fatty fish had lower microbial counts compared to their fresh samples because smoking reduces the microbial load on fish. Biochemical characterization carried out on all isolates confirmed Gram-negative bacterial isolates. The proximate composition show that water is the most affected nutrient during the hot smoking of both the fresh fish sample and the fresh fatty sample with a corresponding increase in protein content. There was a significant difference (p〈 0.05) in proximate composition of smoked product of fresh fatty fish and the fresh lean fish. The colony counts of different parts of the fish reveals that majority of the microorganisms is found in the guts followed by gills and the lowest in the skin this is the pattern in the two fresh fish but for smoked fish the gut is usually removed before smoking.

    Description: The fatty acid composition of oil extracted from the viscera of African catfish, Clarias gariepinus caught from a fish farm in New Bussa was investigated with a view to prove their usefulness. A total of 20 fatty acids were obtained out of which five were identified. Lauric, Palmitic and Stearic acids were the main saturated and monounsaturated fatty acids respectively. The principal acids in the polyunsaturated group were Oleic and Linoleic acids. C. gariepinus viscera is constituted of polyunsaturated fatty acids which make it a valuable pharmaceutical raw material rather than waste.

    Description: The consumption pattern of fermented fish product was conducted to determine the awareness, acceptability and usage with different local spices commonly found in different geographical areas among three ethnic groups in Nigeria. The study was carried out using a well formulated questionnaire as instrument of data collection to Kebbi state for the Hausas, Oyo state for the Yoruba and Anambra for the Igbos. A representative sample size of 600 respondents was selected, Copies of the questionnaire were administered directly through personal visit and interviews. Samples of fermented fish were prepared with soup and served for palatability test. Majority of the people interviewed were between the ages of 20-40 years. About 40% of the respondents were knowledgeable and had attained tertiary education and majority 55.5% were civil servants. About 75% of the respondents have knowledge of fermented fish and have tasted them before while 25% have not known of fermented fish at all. Most of the respondents knew of fermentation of other foods apart fish such as cassava, corn, melon, milk, locust bean etc. Analysis of the data on consumption pattern shows that 67% use fermented fish as condiment, while 18.33% prefer to use it as meal and about 14-15% used it as sauce or soup. A quality attribute exercise shows that fermented fish with or without spice is mostly acceptable among all the ethnic groups.

    Description: The effect of wood types on the nutrient composition of smoked dried fish was carried out using Citharinus citharus. The wood types used for the experiment were Neem, Parkia and Terminalia. The fish samples were smoked dried to constant weight under the same conditions using the three wood types. Proximate nutrient composition of the fish samples and phytochemical analysis of the wood types was determined. Sensory evaluation on the organoleptic properties of the smoked fish samples was also conducted using a test panel to determine the general acceptability of the fish products in relation to the wood type used. Result of the proximate nutrient composition showed that fish sample smoked dried with Terminalia had the highest percentage of protein followed by that of Parkia. Fat content was highest in the fish sample smoked dried with Neem tree. The result of the phytochemical analysis of the wood types revealed the presence of high levels of tannin in Neem, tannins and phenolic compounds in Parkia. Organoleptic evaluation of the products showed that the fish samples smoked dried with Terminalia had the highest general acceptability.

    Description: The proximate composition, mineral content and amino acid profile of Synodontis membraneceous, Oreochromis niloticus and Pellonula afzeluisi was conducted. Results showed that P. afzeluisi had the highest crude protein content (73.00%) amino acid and mineral content. This was followed by O. niloticus (57.87%) and S. membraneceous (54.56%). Organoleptic analysis however showed that O. niloticus had significant overall acceptability, taste and aroma.

    Description: Six (6) Samples of commercially important freshwater fishes: Clarias anguillaris, Lates niloticus, Hemisynodontis membranaceus, Oreochromis niloticus, Citharinus cithrrus and Momyrus rume from Lake Kainji, Nigeria were analyzed during the dry and wet seasons to assess the variation in nutrient and mineral contents using standard procedures in wet weight basis. Result showed high nutrient content in both dry and wet samples. Mineral content were generally low except for Na and Ca among all the samples. Pb and Cd were not detected. Statistical analysis (P〉0.05) showed no significant difference between dry and wet samples.

    Description: The experiment was conduted to determine the effects of fermented clupeid paste as a substitute for fish meal in the diet of Clarias gariepinus fingerlings in hapa nets. Five (5) diets (40% crude protcein) containing fishmeal substituted with 0% (control), 25%, 50%, and 100% ferment clupeid paste were formulated. The fish fingerlings of mean weight 10.83 ~c 0.37g were fed to satiation at body weight twice per day for 30 days in hapa nets. It was observed at the end of the feeding trial that fish fed with 50% fermented paste along With 50%fish meal gave the highest final weight (FW = 19.29g) mean weight gain (MWG= 8.47g), daily growth (DGR =0.28g/day), specific growth rate (SGR 1.92%/day) and total fish production (TFP) of 1.93kg/m3. The feed conversion ratio of 1.47 was best in Diet l (Control). Growth was significantly affected (P〈0.05) and total fish production (TFP) among the treatments. Based on the results obtained from this experiment, 50% substitution level of fermnted clupeid paste with fish meal is considered the optimum inclusion level for the growth of African mud catfish, C. gariepinus fingerrlings production in hapa nets.
