几种主要淡水鱼类温度基准值的研究

为保护水域生态环境的平衡，合理利用水资源和为制定发电厂热水排放的温度标准，提供有关水生生物的温度基准值，对青鱼、草鱼、链、镛和鲤等七种主要淡水经济鱼类作了温度基准值的研究，提出了最适生长温度，最大致死温度及短期暴露最大高温度基准值，以作为确保水生生物能正常生长与繁殖情况下，环境温度的评价标准，研究结果经鉴定确认可以作为制定渔业用水区温水排放标准的依据，同时也对温水或温流水养殖的管理有参考意义。

STUDIES ON THE CRITERIA OF WATER TEMPERATURE FOR MAJOR CULTURED FRESHWATER FISHES

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.
