Thermal tolerance limit and oxygen consumption rates of Labeo gonius (Hamilton, 1822) fingerlings acclimated to four different temperatures

Abstract

An experiment was conducted to evaluate the thermal tolerance limit and oxygen consumption rates of Labeo gonius (6.23±0.19 g) fingerlings acclimated to four different temperatures (27, 30, 33 and 36 °C) for a period of 60 days. Critical thermal maxima, CTmax (40.97±0.05, 41.89±0.05, 42.69±0.04 and 43.05±0.05) and critical thermal minima, CTmin (12.72±0.04, 13.62±0.04, 13.99±0.05 and 14.39±0.021) increased significantly (p
