摘要: 对日本囊对虾Marsupenaeus japonicus在不同条件下的无机磷、亚硝酸氮、硝酸氮、氨氮的代谢率进行了测定。结果表明:温度、体质量、盐度、pH值和摄食状态对其代谢存在影响。无机磷、硝酸氮、氨氮的代谢率与体质量呈负相关, 而亚硝酸氮的代谢率与体质量随体质量的上升而增大;在20~30 ℃的温度范围内,随着温度的上升,日本囊对虾磷、亚硝酸氮、硝酸氮、氨氮的代谢率均上升;在10‰~31‰的盐度范围内,随着盐度的升高,日本囊对虾(6.739±0.023)g磷、亚硝酸氮的代谢率升高,当盐度为31‰盐度时,磷代谢率达到(0.736±0.002)μg·g-1·h-1,亚硝酸氮代谢率为(0.0778±0.011)μg·g-1·h-1,而硝酸氮、氨氮的代谢率与盐度呈负相关,当盐度为31‰时,硝酸氮的代谢率降为(0.257±0.207)μg·g-1·h-1,氨氮代谢率降为(4.445±0.259)μg·g-1·h-1;在7.5~9.0的pH值范围内,随着pH值的升高,日本囊对虾(6.749±0.013)g磷的代谢率明显下降,氨氮、硝酸氮的代谢率提高,亚硝酸氮的代谢率在pH值为8.5时达到最大值,后又呈下降趋势;日本囊对虾(6.729±0.028)g摄食配合饲料,饱食状态下磷、亚硝酸氮、硝酸氮、氨氮的代谢率比饥饿状态下分别提高了272.02%、91.67%、795.38%、98.54%。

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) μg·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%.
