Effect of two fishing baits on catch composition of two traditional fishing traps in the upper Nun River, Niger Delta, Nigeria
The effect of two fishing baits on the catch composition of two traditional fishing traps were investigated between January and December, 2011 in the Upper Nun Rivers, Niger Delta. The traps were set at the littoral zone of the river, baited with Groundnut cake and fresh palm fruit. The Malian trap baited with Groundnut cake caught the highest number (31) of fish species with Species Diversity index of 1.00, while Ikara trap without bait caught the least number of fish species with Species Diversity Index of 0.32. The dominant species in the catches of the traps baited with Groundnut Cake were Synodontis sorex (15.45%), Synodontis clarias (10.57%), Clarias gariepinus (8.54%) and Hetcerobranchus bidorsalis (6.50%) in the small mesh sized Malian traps, while the large mesh sized Malian trap, synodontis sorex (9.05%), synodontis clarias (10.55%), Clarias gariepinus (6.03%) and Distichodus brevipinis (6.50%) were dominant. Mormyrus deliciosus was only caught in Malian trap. In both traps baited with fresh palm fruit, Heterobrancus bidorsalis, Clarias gariepinus, Oreochromis niloticus and Tilapia zilli dominated the catches. Traps not baited were dominated by Clariids. A significant difference was also observed in the weights of fish caught with different baits. The results from this study revealed that, groundnut cake is more efficient than fresh palm fruit as bait in catching freshwater fish.
