Oxygen Consumption and Ammonia-N Excretion Rates of Crassostrea rivularis
摘要
Abstract
The oxygen consumption and ammonia-N excretion rates of Crassostrea rivularis were studied in laboratory by method of experimental ecology.The results showed that the oxygen consumption and ammonia-N excretion rates of Crassostrea rivularis were negatively correlated with its body weight at the test temperature (13- 33 ℃), and their relationships could be expressed by a power function as: Y = a W-b.The relationship of The oxygen consumption rate of Crassostrea rivularis and temperature could be expressed by a quadratic function as: Ro=-c+b1t-b2t2, At 13-33 ℃, The oxygen consumption rate of Crassostrea rivularis was 0.626- 2.354 mg· g-1· h-1.The oxygen consumption rate increased with increasing water temperature at 13 -28℃, and reached peak value at 28℃, and began to decrease at 33 ℃.The relationship of Ammonia-N excretion rate of Crassostrea rivularis and temperature could be expressed by a exponential function as: RN=c1edlt, within the test temperature (13-33 ℃), Ammonia-N excretion rate of Crassostrea rivularis was 0.075- 0.318 mg·g-1 · h-1, and which markedly increased with increasing water temperature.The respiratory and excretion Q10 ranged from 0.631- 3.399 and 1.046- 2.288, respectively.As for different size Crassostrea rivularis, the higher no / nN was observed at 28 ℃.ANOVA showed that body weight, water temperature and both interaction had significant effects on the oxygen consumption and ammonia-N excretion rates of Crassostrea rivularis (P＜0.01).The routine metabolism of Crassostrea rivularis under treatment was obviously higher than the standard metabolism, and the oxygen consumption and ammonia-N excretion rates increased by 46.8 ％ and 67.7 ％, respectively.关键词
