Abstract The seasonal changes in composition and diversity index of the dominant species of fish were monthly monitored in the Dianshan Lake from January to November 2013 by a 2.0 cm net trawl for 30 minutes each trawling, and the fish community status and individual composition structure were evaluated by abundance biomass comparison curve (ABC) and biomass spectrum methods. It was found that there was difference in the dominant species of fish in the four seasons: largefin bitterling Acheilognathus macropterus, crucian carp Carassius auratus and silver carp Hypophthalmichthys molitrix in spring; largefin bitterling, crucian carp and yellowfin Xenocypris macrolepis in summer; yellowfin, crucian carp, yellowfin and whitefish Cultrichthys erythropterus in autumn; and crucian carp, common carp Cyprinus carpio and estuarine tapertail anchovy Coilia nasus in winter. There was the minimal species diversity in spring and the maximal in autumn. The ABC curve showed that the quantitative dominance curve was higher than the dominance curve of biomass in the Dianshan Lake in spring and winter, and the quantitative dominance curve overlaped almost with the dominance curve of biomass in the Dianshan Lake in summer and autumn, indicating that the fish community structure was still in a state of great disturbance. The fish species were found to be primarily composed of small fish in the Dianshan Lake by biomass spectrum method. It is suggested that water quality in the Dianshan Lake be improved, fishing intensity be reduced, and the intensity of proliferation and release be increased in order to protect the fishery resources in the Dianshan Lake.
