多因子对日本囊对虾Marsupenaeus japontcus氮磷代谢的影响
Effects of Several Factors on Nitrogen and Phosphorus Metabolism in Marsupenaeus japonicus
摘要
Abstract
The experiment determined the metabolic rates of inorganic phosphorus, nitrite nitrogen, nitrate nitrogen and ammonia on M. japonicus under different conditions. Results show that : temperature, weight, salinity, pH and feeding status effect metabolism. The metabolic rates of Phosphorus, nitrate nitrogen and ammonia nitrogen were negatively correlated with weight, but the metabolic rates of nitrite nitrogen decreased when weight increased. In the range of 20 ~30 ℃, as the temperature rose, the metabolic rates of phosphorus, nitrite nitrogen, nitrate nitrogen and ammonia increased. In the range of 10‰ ~31‰, as the salinity increased, the metabolic rates of phosphorus and nitrite nitrogen by M. japonicus (6. 739 ±0. 023) g increased, when the salinity is 31, the metabolic rates of phosphorus and nitrite nitrogen is (0. 736 ±0. 002) μg·g-1·h-1, (0.0778 ±0.011)μ·g-1·h-1, the metabolic rates of nitrate nitrogen, ammonia nitrogen decreased, when the salinity is 31, the metabolic rates of nitrate nitrogen, ammonia nitrogen is (0.257 ±0.207) μg·g-1·h-1, (4.445±0.259) μg·g-1·h-1. In the range of 7. 5 ~9.0, as the pH increased, the metabolic rates of phosphorus by M.japonicus (6. 749 ±0. 013) g decreased significantly, the metabolic rates of nitrate nitrogen and ammonia nitrogen increased. When pH was 8.5, the metabolic rates of nitrite nitrogen reached the maximum. Relative to the state of hunger, in the condition of feeding formula foodstuff, the metabolic rates of phosphate, nitrite nitrogen, nitrate nitrogen, ammonia nitrogen by M.japonicus (6.729 ±0.028) g, increased 272.02%, 91.67%, 795.38%, 98.54%.关键词
