Effects of salinity on oxygen consumption rate and ammonia-N excretion rate of Perinereis aibuhitensis
摘要
Abstract
The oxygen consumption rate and ammonia-N excretion rate of Perinereis aibuhitensis were determined at different salinity (8, 16, 24, 32, 40 and 45) in order to optimize P. aibuhitensis farming conditions and promote the rational development and utilization of Nereis resources. The results showed that (1) The oxygen consumption rate and ammonia-N excretion rate were significantly affected by salinity (P<0.05); (2) oxygen consumption rate first decreased and then increased with the increase of salinity at the range of 8 to 32, which was the lowest (0.22±0.01 mg /g·h) at the salinity of 24, and reached the maximum value (0.37±0.05 mg /(g·h)) at 32; (3) ammonia-N excretion rate first decreased and then increased with the increase of salinity at the range of 8 to 40. At salinity of 24, ammonia-N excretion rate was the lowest, and reached the maximum value at the salinity of 40;(4) O︰N ratio increased at the salinity range of 8 to 40, and showed little fluctuation. At the range of 24 and 32, O︰N ratios were 130.84 and 126.47, respectively, which were pretty high, and the ratio sharply declined to 13.30 at the salinity of 40, and then it increased again. The results suggest that the optimal salinity of P. aibuhitensis would be at the range of 24 to 32.关键词
