Effects of bait types on fish congregation and catch efficiency of castnet in Lake Kainji
The effect of baits, rice bran (Oryza sativa L.) and corn bran (Zea mays L.) on fish aggregation and catch efficiency of castnet in Lake Kainji was conducted. 25.4mm stretched mesh size multifilament (PA) nylon net was used for the construction of castnet. The experiment was Complete Randomized Design (CRD) with three replications for nineteen consecutive fishing days. Three treatments were employed; castnetting after baiting with rice bran, with corn bran, and castneting without bait (control). Thirteen fish species were caught from eight families. The number of fish caught was 336, of which 48.5 and 27.1 % were caught with corn bran and without bait while castnetting with rice bran recorded the least (24.4%). The biomass of fish caught was 4627.7g (4.6kg) of which the highest percentages 51.4 and 28.6% followed same trend as that of number of fish caught. Comparison of the overall number and biomass of fish capture indicated that Tilapia zillii ranked highest, followed by Citharinus citharus and Hydrocynus forskalii.
