  • The oxygen consumption rate and ammonia excretion rate of Soletellina acuta were examined by using the indoor experimental ecological methods. The results showed that the oxygen consumption rate and ammonia excretion rate of S. acuta had negative power function correlation with the body mass cultured at 16-32 ℃ . At 16～32 ℃ the oxygen consumption rate of S. acuta was exponentially correlated with temperature. The oxygen consumption rate increased with the temperature,reaching the peak value at 32 ℃ ,and then decreased when the temperature was over 32 ℃ . At 16-36 ℃ the correlation between the ammonia excretion rate and temperature could be expressed with a quadratic polynomial function,and the ammonia excretion rate was maximum at 28 ℃ . The Q10 value of respiration ranged from 0. 547 to 3. 660 and the Q10 value of excretion ranged from 0. 235 to 2. 515 in S. acuta. The effects of temperature on the oxygen consumption rate and ammonia excretion rate were both significant. The ratio between the respiratory oxygen atoms and excretory ammonia nitrogen atoms （O∶N） of S. acuta ranged from 4. 312 to 21. 874. The O ∶ N ratio of S. acuta with all sizes increased as the temperature rose.

Abstract: The oxygen consumption rate and ammonia excretion rate of Soletellina acuta were examined by using the indoor experimental ecological methods. The results showed that the oxygen consumption rate and ammonia excretion rate of S. acuta had negative power function correlation with the body mass cultured at 16-32 ℃ . At 16～32 ℃ the oxygen consumption rate of S. acuta was exponentially correlated with temperature. The oxygen consumption rate increased with the temperature,reaching the peak value at 32 ℃ ,and then decreased when the temperature was over 32 ℃ . At 16-36 ℃ the correlation between the ammonia excretion rate and temperature could be expressed with a quadratic polynomial function,and the ammonia excretion rate was maximum at 28 ℃ . The Q10 value of respiration ranged from 0. 547 to 3. 660 and the Q10 value of excretion ranged from 0. 235 to 2. 515 in S. acuta. The effects of temperature on the oxygen consumption rate and ammonia excretion rate were both significant. The ratio between the respiratory oxygen atoms and excretory ammonia nitrogen atoms （O∶N） of S. acuta ranged from 4. 312 to 21. 874. The O ∶ N ratio of S. acuta with all sizes increased as the temperature rose.
