摘要
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。
The effects of temperature on oxygen consumption rate and ammonia excretion rate of the constricted tagelus(Sinonovacula constricta) were studied in laboratory. The results showed that under the controlled conditions of ambient temperature 15~30℃, the relationship between oxygen consumption rate(O) and dry weight of soft tissueW(g) can be represented by the allometric equation O=aW b, The relationship between ammonia excretion rate(N) and dry weight of soft tissue W(g) can also be represented by the allometric equation N=cW d. It is indicated that the oxygen consumption rate(O S) and ammonia excretion rate(N a) are correlated positively with the water temperature and the high temperature can reduce the level of protein metabolism at the temperature range 15~30℃. The linear regression relationships among oxygen consumption rate(O) and temperature and dry weight of soft-tissue can be described by O=-0.3703+0.3204W+0.0298T, and ammonia excretion rate(N) can be done by N=-154.0677+69.7488W+7.9332T, the multiple relation coeffreient were 0.9773 and 0.9228 respectively.
