在室内实验条件下 ,测定了体重、温度和饥饿对口虾蛄耗氧率和排氨率的影响。实验结果表明 ,随个体重量的增加 ,口虾蛄单位体重的耗氧率和排氨率均减小 ,呈负相关的幂指数关系 ,均符合 Y=a Wb模式。随温度增加 ,口虾蛄的耗氧率、排氨率均增加。饥饿对口虾蛄的代谢有明显的影响。随饥饿天数增加口虾蛄的耗氧率和排氨率明显下降 ,16d后分别下降约 4 7%和 50 % ,且大个体下降幅度较大。 Under laboratory conditions, the effects of body weight, temperature and starvation on oxygen consumption rate and ammonia excretion rate of shrimp were studied. The experimental results showed that with the increase of body weight, the oxygen consumption rate and ammonia excretion rate per unit body weight of mouthmouth shrimp decreased, showing a negative correlation power exponent, all in line with the Y = a Wb model. With the increase of temperature, the oxygen consumption rate and ammonia excretion rate increased. Hunger on the metabolism of shrimps have a significant impact. With the increase of the number of days of starvation, the oxygen consumption rate and ammonia excretion rate of the mouth shrimp decreased significantly, and decreased by about 47% and 50% respectively after 16 days, with a significant decrease in the large individual.
