| dc.description.abstract | Some aspects of the biology of the family Characidae in s studied between the months of March and December, 3. Commercial fish landings in the market were the main source of the fish samples which were collected once or twice weekly. Only two genera of the family Characidae were found in the samples. The genus Hydrocynus (the Tigerfish) was represented by the species Hydrocynus vittatus Castelnau while the genus Alestes was made up of two species namely Alestes nurse Ruppell and Alestes macrolepidotus Cuvier and Valenciennes. Alestes nurse was the most abundant species of the family Characidae in Zaria followed by Alestes macrolepidotus. The rarest was Hydrocynus vittatus. The size distribution showed some marked differences ween the males and females of the same species. The mean condition factor was determined for the various species and was found to be high throughout the period of investigation, The fishes exhibited some diversity in their feeding habits and also fed on a variety of food items. They were all pelagic feeders. Hydrocynus vittatus was principally a piscivore. Alestes macrolepidotus and Alestes nurse were omnivores feeding principally on plants, insects and detritus | en_US |
