采用静水封闭的实验方法研究了温度（8℃、14℃、20℃、26℃、31℃）和盐度（5、15、25、35）对体质量353．2 g岱衢族大黄鱼（ Pseudosciaena crocea）排氨率和耗氧率的影响，同时测定其在不同温度下浮头点和窒息点。结果显示，随着温度升高，排氨率和耗氧率均先增大后减小，在26℃时两者达到最大值，温度对两者存在显著影响（ P＜0?05）；随着盐度的升高，排氨率和耗氧率均先增大后减小，盐度25时两者达到最大值，盐度对两者存在显著影响（ P＜0．05）；浮头点和窒息点随着温度上升呈现先降低后升高趋势，在14℃达最小值，温度对浮头点和窒息点存在显著影响（P＜0．05）。研究认为，在温度26℃、盐度25的环境条件下，岱衢族大黄鱼代谢旺盛，是其比较适合的生长条件；14℃可以作为苗种运输时的温度。

The effects of temperature ( 8 ℃, 14 ℃, 20 ℃, 26 ℃, 31 ℃) and salinity ( 5, 15, 25, 35 ) on ammonia excretion rate and oxygen consumption rate of Dai-qu stock large yellow croaker ( Pseudosciaena crocea) with average body weight of 353.2 g were determined by sealed-still water experimental methods, and the floating point and the suffocation point at different temperatures were measured as well. The results showed that both of the ammonia excretion rate and oxygen consumption rate of Dai-qu large yellow croaker were both increased first and then decreased with temperature rose, and they reached to the maximum value of 26 ℃. Water temperature had significant effects on ammonia excretion rate and oxygen consumption rate ( P<0.05) . Ammonia excretion rate and oxygen consumption of the fish increased first and then reduced with salinity rose, and they reached to the maximum value of salinity 25. Salinity had significant effects on the ammonia excretion rate and oxygen consumption rate (P<0.05). With the temperature rose, the floating point and suffocation point appeared an initial reduce and followed an increase. At 14℃, both of floating point and suffocation point had reached to the minimum value. Temperature had significant effects on floating point and suffocation point ( P<0.05) . On the basis of the results, it is suggested that the metabolism of Dai-qu Stock large yellow croaker was fast under the watewr temperature of 26℃ and the salinity of 25 , which is preferable for the growth and the water temperature of 14 ℃ is suitable for the fingerlings transportation.
