摘  要：
以波纹巴非蛤(Paphia undulate)为实验材料,比较了温度和规格对其耗氧率和排氨率的影响。实验温度设为15、20、25和30℃,选择不同大小的A和B两种规格,其壳长分别为(4.35±0.19)cm和(3.53±0.15)cm。结果表明,温度对耗氧率和排氨率存在显著影响(P<0.05);规格对耗氧率存在显著影响(P<0.05),而对排氨率影响不显著(P>0.05)。在温度15～30℃,波纹巴非蛤的耗氧率随温度升高而增大。在15℃和20℃条件下,B组的耗氧率显著大于A组(P<0.05);在25℃和30℃条件下,B组的耗氧率大于A组,但差异不显著(P>0.05)。温度15～30℃,波纹巴非蛤的排氨率随温度升高而增大,但2组排氨率没有显著差异(P>0.05)。

摘  要：
The present study reported that the effects of temperature and size on metabolism of Paphia undulate under controlled conditions indoors.The temperature levels were 15,20,25 and 30℃,and two size groups designed as A and B were set with the mean shell length of(4.35 ± 0.19) cm and (3.53 ± 0.15) cm,respectively.It was found that temperature had significant effects on oxygen consumption rate and ammonia excretory rate (P < 0.05).The size had significant effects on oxygen consumption rate (P < 0.05),while insignificant effects on ammonia excretory rate were detected (P > 0.05).The oxygen consumption rate of Paphia undulate increased with temperature increasing from 15 to 30℃.At 15 and 20℃,the oxygen consumption rate of the B group was significantly larger than that of the A groups (P < 0.05).At 25 and 30℃,however,there were insignificant differences in oxygen consumption rate between the two size groups (P > 0.05).The ammonia excretory rate of Paphia undulate increased with temperature increasing from 15 to 30℃.At 15,20,25 and 30℃,there were insignificant differences in the ammonia excretory rate between the two size groups (P > 0.05).
