2007年9月至2008年5月在海州湾采集15个站点的底泥样品,对大型底栖动物丰度和生物量进行调查研究。共采集到38种大型底栖动物,其中多毛类环节动物14种,甲壳动物5种,软体动物14种,棘皮动物1种,鱼类3种,扁形动物1种。春季平均生物量为3.3 g/m2,平均丰度为164个/m2;秋季平均生物量为26.8 g/m2,平均丰度为180个/m2。本次调查与1959~1960年和2000~2001年南黄海的调查结果相比较,生物量有所下降。
Macrobenthos harvested from 15 sites in Haizhou Bay during September 2007 and May 2008 were investigated.In total,38 species were collected,including 14 species of Polychaeta,5 species of Crustacea,14 species of Mollusca,1 species of Echinoderma,3 species of Fishes and 1 species of Platyhelminthes.The average biomass was 3.3 g/m2,and the average abundance was 164 ind/m2 in spring.The average biomass was 26.8 g/m2,and the average abundance was 180 ind/m2 in autumn.The average biomass of macrobenthos in Haizhou Bay has decreased compared with the national comprehensive ocean investigation results during 1959~1960 and 2000~2001 in the Southern Yellow sea.
