Based on the gillnet surveys and bottom trawl surveys in the coastal waters of Leizhou in Beibu Gulf in April,June and July,2005,the fish community structure was analyzed.The preliminary results indicated that silver pomfret(Stromateoides argenteus) was the most dominant species in this area,while other dominant species varied with changing waters and seasons.Moreover,calculations of the species richness R,Shannon diversity index H' and evenness index J' were respectively made for the fish community in spring and summer in this area.In addition,cluster analysis revealed that fish community structure existed,spatial and temporal heterogeneity to some extent,with the temporal heterogeneity more obvious than the spatial heterogeneity.And different ecotypes showed among different fish communities.Furthermore,a portion of datum showed that some results greatly varied with the nets that we used.
