The results showed that the respiration rate of J1Jm (Japan♀×Japan♂) and C1Jm (China♀×Japan♂) increased with increase in water temperature, but significantly decreased at over 18℃. The respiration rate in "Chinese red" and its half-sib families (C1Rh, J7Rh, RjRh) sharply decreased at 21℃, indicating that the "Chinese red" and its half-sib families adopted higher temperature. The changes in NH4-N excretion rate showed a similar tendency to the respiration during the experiment.
