Based on the data collected in seasonal bottom trawl surveys in Haizhou Bay and adjacent waters in March,May,July,September and December,2011,the variations in the composition and characteristics of the ecological groups of fish communities were studied.The main basis for the division of ecological groups were adapting temperate,spawning,feeding and migratory types.The results showed that a total of 96 fish species were captured in the surveys,which belonged to 71 genera,44 families and 13 orders.Fifty eight fish species were selected to study the ecological groups,which accounted for more than 95%of the total biomass of all fish species.Warm temperate fish species were dominant in Haizhou Bay,with their total biomass and number of species accounted for over40%in each season.Species with pelagic eggs and those withdemersal and adhesive eggs were the main ecological groups in Haizhou Bay,with their biomass accounted for 48.17%and 31.19%of the total biomass of fish community in Haizhou Bay,respectively.With respect to feeding types,benthivores were the main feeding type in each season.The proportion of the biomass and number of migratory(including short-and long-distances)fish species were more than those of local species.According to the result ofχ2-text,ecological groups showedobvious seasonal variations.Thealternation of different fish species was obvious,and the change of dominant fish species were various between seasons,presenting similar variations with the ecological groups.
