摘要：
The relative efficiencies of gill nets presently used in Lake Nubia fishing were compared. 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. Although individual nets undergo seasonal fluctuations in CUE [catch per unit effort] this does not substantially affect their order of merit. The role of water characteristics on fish population distribution and subsequent changes in the CUE was also noted.
