摘要
2006年9月,南隍城岛附近海域首次发生由塔玛亚历山大藻(Alexandrium tamarense)引发的大规模赤潮,面积约2.37 km2,最大细胞丰度2.334×108cell/L,大量衰亡赤潮生物的分解消耗水体的溶解氧,引起中下层水体严重缺氧,导致当地网箱养殖的鱼类全部死亡,藻体分泌的麻痹性贝毒(PSP),导致岸边的皱纹盘鲍近一半死亡。通过对这次赤潮的研究认为:其成因主要是由船舶压舱水排海带来赤潮生物物种,大量陆源有机物、营养盐类的排入和大规模贝类筏式养殖的自身污染为赤潮生物的暴发性繁殖提供了丰富的物质基础,适宜的水文气象条件为赤潮的发生提供了良好的繁殖环境。
In September 2006, the red tide in the sea area of the Nanhuangcheng island was investigated, which was the first record of red tide caused by Alexandrium tamarense in Yantai. The area of the red tide was about 2.37 square kilometers, and the highest cell abundance of Alexandrium tamarense reached 2. 334 108 cells/L. Because declines of the large number of red tide organism consumed dissolved oxygen in water, oxygen in lower water lacked seriously, leading all the fishes of cage culture to death. Nearly half of the Haliotis discus cultured on the shore were caused to die by Paralytic Shellfish Poisoning （PSP） secreted by Alexandrium tamarense. The main cause of red tide was that ballast water discharge brought about red tide organism. Large number of organic matters of land-based sources, nutrient salt ejected into the sea and self-pollution of mass culture＇s of Shellfish raft provided rich material basis for outbreak of proliferation of red tide organism. And the hydrometeorological conditions provided a good physical environment for the occurrence of the red tide.
