1999年 4～ 6月 ,采用室内实验生态学方法对栉孔扇贝的耗氧率和排氨率进行了研究 .结果表明 ,在适宜的温度范围内 ,栉孔扇贝的耗氧率和排氨率均与温度成正比 ,而与体重呈负相关关系 .在实验室温度 (8～ 2 8℃ )条件下 ,栉孔扇贝的耗氧率为 0 .48～ 9.0 9mg·g-1·h-1,排氨率为 0 .0 5～ 1 0 1mg·g-1·h-1.其中耗氧率在 2 3℃时达到最高值 ,2 8℃时开始下降 ,而排氨率则呈持续升高趋势 .栉孔扇贝的日常代谢明显高于标准代谢 ,耗氧率和排氨率平均值分别提高约 35 .8%和 75 .9% .
The oxygen consumption rate and ammonia excretion rate of the scallop Chlamys farreri were studied by indoor experimental ecology from April to June in 1999. The results showed that the oxygen consumption rate and ammonia excretion rate Both were directly proportional to temperature and negatively correlated with body weight.The oxygen consumption rate of chlamys farreri was 0.48-9.9 mg · g-1 · h-1 at the laboratory temperature (8 ~ 28 ℃) , And the ammonia excretion rate was 0.050-1.10 mg · g-1 · h-1, in which the oxygen consumption rate reached the highest value at 23 ℃, then decreased at 28 ℃, and the ammonia excretion rate was continuously rising The daily metabolic rate of Zhikong scallop was significantly higher than that of standard metabolism, and the average oxygen consumption rate and ammonia excretion rate increased by 35.8% and 75.9% respectively.
