温度往往是海水饵料动物培养中的重要限制因素,是影响水生动物代谢的重要环境因子。在一定范围内升温,水生动物的代谢往往表现出增强的趋势[1];而且枝角类本身的排泄物以氨为主,当大量培养或环境改变时,由于氨的积累所产生的毒性就不能忽略。因此,饵料动物排氨率的高低不仅反映 Temperature is often an important limiting factor in seawater animal culture and is an important environmental factor affecting the metabolism of aquatic animals. In a certain range of warming, the metabolism of aquatic animals tend to show an increasing trend [1]; and dendrites themselves are mainly ammonia-based excretion, when a large number of culture or environmental changes, due to the accumulation of ammonia toxicity Can not be ignored. Therefore, the level of dietary ammonia excretion is not only reflected
