本文对大连湾西部海区养殖的紫贻贝出现的大量死亡和各种异常情况做了记叙,通过该海区载苗量增加6.5倍和对各样异常情况的分析,说明了死亡原因是超环境容纳量养殖,破坏了生态平衡严重缺乏饵料所致。在最佳环境容纳量出台前,为急生产所需,可暂接受灾台筏死亡后剩余数量,即“极限环境容纳量”——22.14亿个为最高限额安排生产。为了更为妥善地解决环境容纳量问题,提出在紫贻贝专养区,实行间套轮养扇贝,牡蛎等台筏载苗量少,饵料耗量不大的新品种;以及在紫贻贝专养区实行贝藻间养,以达到改善水域生态环境的目的。
In this paper, a large number of deaths and abnormalities of purple mussel cultured in the western part of Dalian Bay are described. Through the increase of 6.5 times the amount of seedlings in this area and the analysis of various anomalies, The amount of aquaculture, undermining the ecological balance of a serious lack of food caused. Before the best environmental capacity is introduced, for emergency production, the remaining amount after the disaster catamaran can be temporarily suspended, that is, the “ultimate environmental capacity” - 2.221 billion for the ceiling production. In order to solve the problem of environmental capacity, a new species with less seedlings and less food consumption was proposed in the mussel raising area of purple mussel. Adopted Bayecium rearing areas in order to achieve the purpose of improving the ecological environment of the waters.
