Abstract

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.
