摘要: 通过实验模拟的测定结果,估算了新生残饵对虾塘养殖环境的可能影响程度.结果表明,两种新生残饵的N、P营养物质溶出速率及其TN与TP、IP与TP比值,随其生成时间的延长均有较大幅度变化,且变化趋势相近.贻贝新生残饵因其分解速率较快,故对养殖水体短期影响较大,但其总体影响却并不大于配合饵料.新生残饵是对虾养殖水环境及其临近浅海环境的主要污染源.

Abstract: Based on determinations of simulation experiment, the influence of newborn remains on environment in shrimp pond is estimated. The results show that the dissolving rates of N and P from two kinds of culturation newborn remains and their TN/TP and IP/TP ratios are varied in a greater range with the lapse of time, and the general changing patterns of the two newborn remains are similar. Because the remains produced by mussel decomposes very fast, it has a great short term influence on cultural environment, but its long term influence is no more serious than that of mixed feed. The newborn remain is a main pollutant source for shrimp cultural environment and its adjacent waters.
