Description:
Studies on the evaluation of Beach Seine net by-catch in Lake Kainji was conducted in Yuna fishing village. The beach seine net of 306m long and 12m depth was used for this experimental fishing trial. The seining took about 2 hours and was done three times in three different sampling locations in the Lake. A total of 24 fish species were caught, two target species, P. afzeliusi and S. leonensis, and 22 fish species obtained from the by-catch. The overall total number of fish caught was 34,939 of which 96.9% was obtained from the target fish Clupeids while the remaining percentages 3.1% were the by-catch fish. The total weight obtained was 66.2kg, out of which the greatest proportion 50.7% was obtained from target fish and the rest percent 49.3% was recorded from the by-catch and discards fish. About 90% of the by-catch was undersized fish from the commercially important freshwater fishes of Lates, Citharinus, Labeo, Tilapias ctc. Recommendation was made on how to improve the use of this fishing gear in order to conserve and sustain the fisheries resources of Lake Kainji.
