    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.

    Description: Comparative studies of monofilament and multifilament gillnets in Lake Kainji was carried out at Monai fishing village of Lake Kainji. A total number of six nets (3 multifilament and 3 monofilament gillnets) each measuring l5 meters in length and 3 meter depth were constructed; Kuralon ropes were used as footrope and headrope, synthetic corks as float and lead as weight. The net were set in the evening (between 5:00pm and 6:00pm) and hauled in the morning (between 8am and 9am) thereby maintaining a soaked time of about l5 hours.The species captured were: Oreochromis niloticus, Oreochromis aureus, Sarotherodon galileus, Tilapia mariae, Synodontis nigaita, Alestes baromoze, Distichodus rostratus, Tilapia dageti. The result obtained from the fish caught shows that Monofilament gill net had a better performance than Multifilament gill net; this was attributed to the looseness and flexibility as well as the transparent nature of the net which makes it invisible in water. However, from the statistical analysis (variance test) carried out, there was no significant (P〉0.05) difference in numbers and weight of fish species caught by the two nets.
