Effect of baits on the efficiency of Malian traps in Lake Kainji
Studies on the effects of two fishing baits on the catch composition of Malian Traps in Lake Kainji were monitored. The Traps were set at Monia fishing village in the southern basin of the Lake Baited with boiled yam (Dioscorea rotundata) and fresh palm fruit (Elaeis guineensis) and were inspected twice daily for seven weeks. The fishes caught comprised of nine (9) species belonging to four (4) families. The result of analysis of variance of the biomass as well as number and percentages of fishes caught in the traps by the baits showed there was no significant difference (P>0.05). However, both baits showed better efficiency for Tilapia zilli, Oreochromis niloticus and Hemichromis fasciatus than other species caught but trap baited with fresh palm fruit had better efficiency for Distichodus restratus and Alestes nurse. There was wide range between the minimum and the maximum size of species caught, which showed the efficiency of the traps capturing small size, juveniles and the adult of large fish species due to small mesh size (1'') net cover of the trap. Recommendations were made for better performance and profitable fishing of Malian traps.
