This study was conducted to investigate the effect of high water temperature on survival and growth performance of Nile tilapia. Two age groups of female Nile tilapia (9 and 50 days after hatching) were reared at 27, 32, 35 and 37°C water temperatures for 45-60 days. At the end of treatment, the mean survival, total weight, total length, daily growth rate and food conversion ratio of both age groups of fishes were significantly reduced at 35 and 37°C compared to 27 and 32°C (p 32°C) results in slow growth, reduce feeding efficiency and increase mortality. This study also demonstrated the possible impact of global warming on natural fishery resources. DOI: 10.3126/on.v8i1.4331
