一、水温水温直接影响鱼类的新陈代谢强度,从而影响鱼类的摄食和生长。水温影响鱼类性腺的发育和决定产卵的时期。水温还影响水体溶氧,间接影响鱼类的生长。池塘的溶氧量随水温的升高而降低,但水温上升鱼类的代谢加强,呼吸加快,耗氧增加,同时池中其他耗氧因子的作用加强。因此, First, the water temperature The water temperature directly affects the fish’s metabolic intensity, thus affecting the fish’s feeding and growth. Water temperature affects the development of fish gonads and the period of oviposition. Water temperature also affects water dissolved oxygen, indirectly affect the growth of fish. Dissolved oxygen in ponds decreased with the increase of water temperature, but the water temperature increased, the metabolism of fish increased, respiration accelerated, oxygen consumption increased, and the role of other oxygen-consuming factors in the pond was strengthened. therefore,
