Description:
Three gillnets of 3” (76mm) mesh-size with a dimension of 15m long, 3m depth and hung at 50% of different plies (ply 2,3, and 6) were constructed in the FCFFT New Bussa fish gear workshop and used at Taada fishing ground for fishing operation in Lake Kainji for 30 days. Twelve fish species belonging to five families were caught. The highest relative percentage of number and biomass was recorded by the net of ply 2 because of the high flexibility or softness of the net ply. The statistical analysis of variance (ANOVA), for both numbers and biomass of fish caught showed that plies 2 and 3, 3 and 6 had no significant difference (1)〉0.05) but there was significant difference (1)〉0.05) for plies 2 and 6. It was concluded that ply 2 multifilament gill net had the best efficiency for entangling and catching of fish species in Lake Kainji. It could be concluded that for effective performance and profitable fishing in Lake Kainji, ply 2 multi-filament gillnet should be used.
