利用实验生态学方法研究了不同温度和体质量对星洲红鱼( Red Tilapia)耗氧率、 排氨率和窒息点的影响.结果显示: 水温15~35 ℃时, 星洲红鱼的耗氧率、 排氨率和窒息点都随着温度的上升而上升, 差异显著( P<0. 05); 耗氧率(Ro)、 排氨率(RA)与温度(T)的线性回归方程分别为: Ro=0. 066 4T+0. 008 6(R2 =0. 969 3)和RA =3. 849 4t+3. 927 5(R2 =0. 916 8). 在体重27. 50~201. 87 g范围内, 耗氧率和排氨率随着体重的上升而减小, 窒息点随着体重的上升而上升, 差异显著(P<0. 05); 耗氧率(Ro)、 排氨率(RA)与体质量(W)的线性回归方程分别为: Ro= -0. 042 2W+0. 312(R2 =0. 989 6)和RA = -4. 281 8 W+26. 4(R2 =0. 988 4). 结果表明, 不同温度和体质量对星洲红鱼耗氧率、 排氨率和窒息点有明显影响.

The effects of temperature and body weight on oxygen consumption rate( OCR) , ammonia excretion rate( AER) and asphyxiation point ( AP) of Red Tilapia was studied with ecological methods in laboratory. The results showed that temperature and weight had significant effects on oxygen consumption rate, ammonia excretion rate and asphyxiation point. From 15~35 ℃, the oxygen consumption rate, ammonia excretion rate and asphyxiation point of Red Tilapia showed an increasing trend as the temperature increasing, and the rate values became obviously different from each other in the range ( P<0. 05). The regressive equation of OCR, AER and the water temperature could be expressed as RO =0. 066 4T+0. 008 6(R2 =0. 969 3)and RA =3. 849 4t+3. 927 5(R2 =0. 916 8). The body weight from 27. 5 g to 201. 87 g, the ox-ygen consumption rate and ammonia excretion rate showed a decreasing trend with the body weight increasing, however , the asphyxiation point was increasing as the increasing level of individual body weight and the difference was significant( P<0. 05). The regressive equation of OCR, AER and the body weight could be expressed as Ro= -0. 042 2W+0. 312 (R2 =0. 989 6)and RA = -4. 281 8W+26. 4(R2 =0. 988 4).
