    Description: The study was conducted to assess consumer's preference of fish products in Yenagoa Metropolis, Bayelsa State. One hundred and ninety consumers were randomly selected for the study. Results showed that fishery products in Yenagoa metropolis include fresh, smoked, fried, dried, canned and frozen fish. Sixty-eight percent of the respondents said that the products are enough, whereas seventy-six percent feel the variety of fishery products is low. Majority of the respondents (86%) preferred fresh fish followed by smoked fish which was preferred by sixty-four percent of the respondents. Age, ethnic grouping, gender, marital status and education did not have any significant influence on the preferences of the consumers (P〉O.05). Major problems identified by the consumers were exorbitant prices of fish because of the activities of middlemen, unhygienic selling environment and scarcity of fish products. Consequently, it is recommended that an adequate system of financing small scale fisheries be evolved to reduce the influence of middlemen; sanitary laws should be enacted and enforced in the fish markets around the metropolis; Establishment of modern fish markets in Yenagoa to boast fish production, aquacultural investors should be attracted.

    Description: The growth, mortality and recruitment pattern of Tympanotonus fuscatus var fuscatus were investigated using shell length (SL) - frequency data obtained from the mangrove swamps of the Bonny River, population. Computer based software package FiSAT (FAO - ICLARM Fish Stock Assessment tool) were used for the analysis. Sampling was done between January to December, 2004. Results obtained showed relatively high growth, low mortality and recruitment pattern with two peaks annually.

    Description: Studies on the food and feeding habit of T. fuscatus var fuscatus from the mangrove swamps of the Bonny River, Niger Delta revealed that the species is a deposit feeder but fed more on algae and protozoa. The variation of food types with season were determined from the numerical and frequency of occurrence methods of food analysis. The algae were of Stephanodiscus, Cosanodiscus. Navicula and Nitzschia species, while the protozoa were Arecella arenaria, Pseudodileptus and Trinema species. Feeding actively occurred at low tides, this coincided with the presence of algae on the mud surface. No qualitative seasonal variation occurred as T. fuscatus var fuscatus fed basically on the primary diets at all seasons.

    Description: The study examined the food habits of Chrysichthys furcatus (catfish) from the artisanal fisheries of the Sombrero River in the Niger Delta; from May 2009 to April 2010. A total of 360 specimens were used for the stomach analysis using a combination of the frequency of occurrence, gravimetric and numerical methods. Data was analysed using Shannon Weaver diversity index (H), Relative diversity (J) and index of relative importance (IRI). The results show that small Chrysichthys 28.55%, 45.23% and 39.20; fish tissues 14.70%, 9.08% and 17.44%; fish parts 25.95%, 18.76% and 18.39% , fish scale 2.60% ,3.93% and 2.55%, insects 25.78%,21.95% and20.12% as the secondary and detritus 2.42%,1.06% and 2.30% as incidental food items. The Shannon Weaver and relative diversity indicate that Chrysichthys furcatus is a predator and had no food preference.
