Abstract :
[en] In man-made Lake Ayame, a 180-day cage culture feeding trial was conducted to investigate the effects of three agricultural by-products - chicken droppings, wheat bran and corn bran- on the survival rates, mean daily weight gain and feed conversion ratio in juveniles of a landlocked population of Sarotherodon melanotheron. Results were compared to those obtained from fishes fed on local commercial diet and a group of unfed fishes. Survival rate (SR), mean daily weight gain (MDWG) and feed conversion radio (FCR) were better for fish fed on the commercial diet (SR : 95,0 +/- 4,2 %, MDWG:0,26 +/-0,00 g/day and FCR: 4,27 +/- 0,47) than for the unfed fish (SR:53,0 +/-0,0%, MDWG: 0,02+/- 0,00 g/day. Of the by-products, corn bran resulted in the best mean daily weight gain (0,09 +/- 0,01 g/day. A significant positive correlation on the dietary dry matter (bêta : 0,98), lipid (bêta :0,99), protein (bêta :0,85) and energy (bêta : 0,98) levels with the mean daily weight gain was also observed.
