| Abstract: | Trawl net samples collected from April to November in 1984 in Laizhou Bayyielded 22 species of main invertebrates, Crustacea and Mollusca among 372 400 in-dividuals totalling 8 843kg. The community species diversity index H was 1.80-2.36, being 2.36 in May, 1.89 in August and 1.80 in November which display thatspecies diversity was medium and community structure rather simple.The distribution of seasonal species diversity H isopleths of May, August andNovember showed that the centra water region of Laizhou Bay and the northernside of the Yellow River mouth are higher than that in adjacent waters. |
