During the survey period, a total of 41 fishery resource species were sampled with a mean density of 2,554,633 ind./km 2 and mean biomass was 32,946 kg/km 2. A total 36 fishery resource species were sampled with a mean density of 3,198,793 ind./km 2 and mean biomass 41,177 kg/km 2 in 29 and it were sampled a total 31 species, mean 1,91,473 ind./ km 2 and 24,716 kg/km 2 in 21. The major individual-dominant species, occupying over 1% of total individuals, were Gomphina veneriformis (2,491,818 ind., 82.2%), Umbonium costatum (221,973 ind., 8.7%), Mactra chinensis (49,879 ind., 2.%), Glossaulax didyma hayashii (49,879 ind., 1.9%), Blepharipoda liberate (37,714 ind., 1.5%) and Paguridae spp. (27,266 ind., 1.1%). The major biomass-dominant species, occupying over 1% of total biomass, were G. veneriformis (25,124 kg, 76.3%), G. didyma hayashii (2,596 kg, 7.9%), M. chinensis (2,24 kg, 6.1%), Ovalipes punctatus (921 kg, 2.8%) and Glossaulax didyma didyma (567 kg, 1.7%). From the cluster analysis based on Bray- Curtis similarity matrix of fourth root transformed data of species number and individuals was divided into 2 different groups of the fishery resource community (Group A-St.1, Group B-Sts. 2, 3, 4). The 29 and 21 mean Shell length (mm) of G. veneriformis was 37.73 mm, 29.76 mm and M. chinensis was 62.3 mm, 44.94 mm, respectively.
