Effect of feed availability on susceptibility of Nile tilapia, Oreochromis niloticus (L.) to environmental zinc toxicity: Growth performance, biochemical response, and zinc bioaccumulation

This paper presents data on the effect of feed availability on growth performance of Nile tilapia and its susceptibility to waterborne zinc toxicity via evaluating growth performance, whole-body measurements, and the biochemical response of Nile tilapia. Feeding fish up to satiation improved their welfare and reduced the impact of zinc toxicity and its bioaccumulation in whole-fish body and vice versa. Zinc exposure deteriorated the welfare of fasted fish or fish fed inadequate diet.
