    Description: Multimesh, multidepth gillnet fleets are useful in assessing fish stock abundance, size distribution and depth distribution. Using data collected on net mesh selectivity for Nile perch, Lates niloticus (L.), in the Kenyan waters of Lake Victoria, suitable mesh sizes for gillnet fleets for use in the Lake Victoria Fisheries Research Project were determined. The modal selection length for Nile perch in the mesh sized used in the earlier experiment were determined, as was the size range vulnerable to capture.Initial trials suggest 60% of the Nile perch swim within 5 m of the bottom. Setting and hauling of the nets is simple and quick, allowing the nets to be used at the same time as other sampling programmes.

    Description: Trawlers can also have adverse biological implications. Bottom trawling disturbs the substrate, the water column and interferes with the breeding ground and the spawning process, especially for tilapines. It can also destroy larvae and eggs of fish, macro and micro-invertebrates at different strata of the lake. Thus, trawling using non-selective mesh nets, may cause overfishing by taking away both the adult and juvenile fish, reducing their potential yield.
