Fishing trials of metal drum trap in the Upper Nun River, Bayelsa, Nigeria
A drum fishing trap was designed and constructed using normal metal drum material. The trap is easy to construct and has high capacity to catch fish. The fishing trap was selective of the specie Chrysichthys nigrodigitatus of the family Bagridae. Total cost of production was N5,000.00 which is affordable by an average artisanal fisher. The preliminary survey of fish composition of the trap January and June, 2013 revealed that a total of eight \{8) fish species belonging to 4 families were observed. The most abundant families were the Bagridae with three \{3) species which constituted 87.82% of the total sample collected, followed by the Mochokidae (7.61%) and Clariidae (3.55%) while the least percentage was Malapteruridae (1.02%).
