以瓦氏黄颡鱼幼鱼为研究对象,测定了温度对其氨氮排泄率的影响。
5) nitrogen excretion
氮排泄率
1.
The oxygen consumption and nitrogen excretion of Pseudosciaena crocea(20～250 g) and Sciaenops ocellatus(150-1 400 g) were tested at different water temperatures(29.
4℃)条件下的耗氧率和氮排泄率进行了测试分析,结果表明:在相同温度条件下,大黄鱼和美国红鱼的耗氧率和氮排泄率取决于鱼体体重,随着体重的增大,耗氧率和氮排泄率降低;而在相同体重条件下,耗氧率和氮排泄率则取决于水温,即随水温的升高,耗氧率和氮排泄率也随之增高。
