Abstract

The paper reports on a survey on gear assessment for the three intensive fishing seasons in Lake Chad (Nigeria). These seasons coincide with the flood period (Nov-Feb), the receding (March-June)and the recession period (July-September 2001). During this year the questionnaires were requested to ten fishers in each of the selected fishing islands. In the flood season, identified fishing gears on the lake included baited and un-baited Malian traps which constituted about 35% of the total gears recorded. While Ndurutu and Heri (Kung)traps represented, each, 3.2% of the total. About 15.9% of fishers employed hook lines of various length and sizes: Another 15.9% of fishers mounted fish fences (Dumba) during the season. Those that employ seine net accounted for about 11.1% while 9.5% use gill nets.The species belonging to the Cichilidae, Claridae and Osteoglossidae families dominated fish catches. During the receding period, hook lines and fences (Dumba) (6.20%) were found to be predominantly used on the lake due to reducing water level, followed by gill net and draw net which accounted for 17.9% and 16.1 % respectively. During the lake recession only two groups of active gears were recorded. Sixty percent of fishers use combined seine net with cutlass and scoop net, while 40% use to combine only cutlass with kabara net. Fish fences (Dumma)during the flood season were mounted with giant Malian traps of abut 1.5m by 0.5m diameter, covered with net of mesh size (6.3mm-25mm).Each Dumba contained between 150 and 2000 of such traps. Larger number of species was recorded from seine net followed by gill nets and the l kilometre multi mesh fleet drift net. The use of seine net and cutlass known as Genima was predominant during the lake recession
