Abstract: This study examines the criteria of water temperature for black carp, grass carp,silver carp, bighead, common carp, etc in the condition of thermal shock.The paper reported the optimum growth temperatures,the maximum lethal temperatures and the short exposure maximum high temperatllres for these fishes.All the criteria can be considered as appraisal values of water temperature for thegrowth and breeding of these fishes.The researeh results also have the importantreference on the management of warm water and flowillg-warm water fishcultivation and the controlling of the outflow nf warm water intO waters wber6the fishes inhabit.
