实验研究温度对不同个体大小缢蛏耗氧率和排氨率的影响。实验结果表明 ,在实验温度(15～ 30℃ )条件下 ,缢蛏的耗氧率 (O) [mg/ h·个 ]和排氨率 (N ) [μg/ h·个 ]与缢蛏软体部干重(W)呈明显的幂函数关系 ;温度的上升使得缢蛏的耗氧率 (OS) [mg/ g· h]、排氨率 (Na) [μg/ g· h]均增大 ;两者之间的比值 (原子数 O∶ N)在 2 0℃时最大 ,随着温度的继续升高其值逐步减小。耗氧率 (O)、排氨率 (N)与温度 (T)、缢蛏软体部干重 (W)二元线形回归方程分别是 :O=- 0 .370 3+0 .32 0 4 W+ 0 .0 2 98T,N =- 15 4 .0 6 77+ 6 9.74 88W+ 7.9332 T。复相关系数 r分别为 0 .9773和0 .92 2 8;F检验表明 ,两个回归方程均极显著。
Effects of Temperature on Oxygen Consumption Rate and Ammonia Excretion Rate of Different Size Smaller. The experimental results showed that the oxygen consumption rate (mg / h · s) and ammonia excretion rate (μg / h · s) of the catfish were significantly lower than those of the catfish (catfish) under the experimental temperature of 15-30 ℃ (W) showed a significant power function. The increase of temperature caused the oxygen consumption rate (OS) [mg / g · h] and ammonia excretion rate (μg / g · h) (Atomic number O: N) was the largest at 20 ℃, and its value gradually decreased with the temperature increasing. Oxygen consumption rate (O), ammonia excretion rate (N) and temperature (T), 缢 蛏 soft body dry weight (W) binary linear regression equation are: O = - 0 .370 3 +0 .32 0 4 W +0 .0 2 98T, N = - 15 4 .0 6 77+ 6 9.74 88W + 7.9332 T. The complex correlation coefficients r were 0.9773 and 0.92 2 8, respectively. F-test showed that both regression equations were extremely significant.
