中文摘要：采用室内实验生态学方法对皱肋文蛤(Meretrix lyrata)的耗氧率和排氨率进行研究。实验结果表明:1)在t为13～33℃,S为22.4条件下或S为13～33,t为27.5℃时,皱肋文蛤的单位体重的耗氧率和排氨率与体重呈负相关的幂函数相关。2)温度对耗氧率和排氨率的影响极显著(P<0.01)。t为13～28℃,耗氧率随温度的升高而增加,t为28℃时,3种规格皱肋文蛤的耗氧率均达到最大值,当t>28℃时,耗氧率反而下降,而排氨率在实验温度范围内则呈持续升高趋势。在不同温度下,皱肋文蛤呼吸率的Q10范围为0.49～2.75,平均为1.56;排泄率的Q10为1.14～3.58,平均为1.96。t为13～28℃时,不同规格皱肋文蛤的O∶N值为8.84～14.15,平均为11.22,而t为33℃时不同规格皱肋文蛤的O∶N值为6.36～7.57,平均为6.89。3)盐度对皱肋文蛤的耗氧率和排氨率影响极显著(P<0.01),并呈峰值变化。在S为13～23时,随着盐度的升高,3种规格皱肋文蛤的耗氧率和排氨率相应增加,在S为23时均达最大值,当盐度增加为28和33时,耗氧率和排氨率呈下降趋势。在S为13～23时,3规格皱肋文蛤的O∶N值随盐度的升高而相应增加,在S为23时,O∶N值达最大值。在盐度增加为28和33时,各规格皱肋文蛤的O∶N值呈下降趋势。在S为33时,O∶N值最低。这些结果可为皱肋文蛤养殖容量研究和贝类能量学研究提供参考。

外文摘要：The oxygen consumption and ammonia excretion rates of Meretrix lyrata were studied in laboratory by means of ecological methods. The results are as the followings： 1） Under the conditions of experimental temperature 13-33 ℃ and salinitie 13-33, the oxygen consumption and ammonia excretion rates of M. lyrata are negatively correlated with its body weight and their relationship may possibly be expressed by power function （i. e. Y=aWb ）. 2） The water temperature has a distinct effect on the oxygen consumption and ammonia excretion rates of M. lyrata with different size （P〈0.01）. The oxygen consumption rate of M. lyrata increases with the increasing of water temperature at 13-28 ℃ and reaches to the maximum at 28 ℃. When the water temperature goes higher than 28 ℃, however, the oxygen consumption rate of M. lyrata decreases, whereas its ammonia excretion rate tends to keep increasing markedly. In different temperature ranges, the respiration rate Q10 of M. lyrata ranges from 0.49-2.75, with the average being 1.56, and its excretion rate Q10 ranges from 1.14-3.58, with the average being 1.96. When the temperature is in the range of 13-28 ℃, the O ： N value of M. lyrata is 8.84-14.15, with the average being 11.22, but at a temperature of 33 ℃ the O ： N value of M. lyrata goes down to 6.36-7.57, with the average being 6.89. 3） The water salinity has also a distinct effect on the oxygen consumption and ammonia excretion rates of M. lyrata with different size （P〈0.01）. When the salinity is in the range of 13-23, the oxygen consumption and ammonia excretion rates of M. lyrata increase with the salinity and reach the maximum at 23. When the salinity increases to 28 and 33, however, the oxygen consumption and ammonia excretion rates of M. lyrata tend to decrease. The O ： N value of M. lyrata increases also with the salinity and reaches to the maximum at 23. When the salinity increases to 28 and 33, the O： N value tends to decrease and goes down to the lowest at 33. All of these results would contribute to investigate carrying capacity of aquiculture for M. byrata and study ocean ecosystem dynamics and shelfish energy.
