摘要
鱼类消化酶的活性大小与其所生活的水环境紧密相连,本文主要分析了生态因子如温度、盐度、pH和重金属离子,饵料(营养成份、含有的外源性酶以及量的多少)对鱼类消化酶活性影响的研究状况,为水产养殖中优化人工饲料和鱼类的健康养殖提供依据。
The activities of digestive enzymes of fish are closely connected with their living environment. In this paper, the relationship between digestive enzymes of fish and ecological factors such as water temperature,salinity, pH, heavy metal ion and diet （ nutrition level, exogenous enzymes and their amount ） were discussed, which could provide a basic information for manufacture of artificial fish diet and for better fish growth.
