| 摘要: |
| 采用生态生理学方法研究了水温和体质量对许氏帆蚌(Hyriopsis schlegelii)耗氧率和排氨率的影响,为育珠蚌养殖生理生态学提供基础资料。用生化培养箱控制水温,winkler碘量法、纳氏试剂比色法测定耗氧率和排氨率。结果表明,在实验温度(9～30℃)条件下,许氏帆蚌的耗氧率为2.504～6.76mg/(kg.h),排氨率为1.963～5.689mg/(kg.h),其中耗氧率和排氨率在27℃达到最高值,30℃均开始下降。在适宜的温度范围内,许氏帆蚌的耗氧率和排氨率均与温度成正比,而与体质量呈负相关。 |

| Abstract: |
| The oxygen consumption and ammonia N-excretion rates of Hyriopsis schlegelii were studied. The result showed that the oxygen consumption and ammonia N-excretion rates of Hyriopsis schlegelii were positively correlated with water temperature, and negatively correlated with its body weight in optimum temperature conditions. Under the test temperature (9～30℃), the oxygen consumption rate ranged from 2.504 to 6.76 mg/(kg.h), and the ammonia N-excretion rate ranged from 1.963 to 5.689 mg/(kg.h) with the water temperature raising, the oxygen consumption rate and ammonia N-excretion rate reached peak value at 27℃, and began to decrease at 30℃. |
