体重、温度和饥饿对口虾蛄呼吸和排泄的影响

摘要

Effects of body weight, temperature and starvation on oxygen consumption rate and ammonia excretion rate of Oratosquilla oratoria were studied under experimental conditions in laboratory. The experimental results indicate that the oxygen consumption rate and ammonia excretion rate are all correlated positively with water temperature and negatively with the body weight. The relationship of oxygen consumption rate and ammonia excretion rate with the body weight of Oratosquilla oratoria can be both expressed by the model of Y=aXb. The oxygen consumption rate and ammonia excretion rate of Oratosquilla oratoria obriously decreased with starvation days increasing, and decreased by 47% and 50% respectively after 16 days.%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=aWb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47%和50%，且大个体下降幅度较大。
