Abstract
The gill nets presently used in Lake Nubia fishing were subjected to a comparative study in regard to their relative efficiency. The results obtained indicate that Mesh 6 netted with Twine 4 is the most effective net, followed by Meshes 2, 4, 8 and 10 respectively.
It has also been shown that, although individual nets undergo seasonal fluctuations in CUE, this does not, substantially affect their order of merit.
The role of water characteristics on fish population distribution and subsequenct changes in the CUE was also noted.
