Abstract:

Seasonal changes in structure of demersal fish assemblages of the Yellow Sea are studied by means of cluster analysis based on bottom trawl surveys from March 1985 to January 1986. simple discriminate analysis is used to test for significant differences in environment characteristics among sampling station groups which show that species composition and biomass is each group and session are associated with bottom water temperature. The cold water mass in the central Yellow Sea plays an important role in distribution of fish. One to three absolutely dominant species in each group usually characterize the grouping area, accounting for more than 40% of the total catch. The similarity values of species composition between seasons are relatively low, all less than 50%.
