영문 초록

Fluctuations in abundance and species composition of the fish were investigated based on species collected by beam trawl in coastal waters off Gwangyang Bay from April to December in 2015. During the studying period, A total of 5,179 fishes were sampled and classified into 31 species, 19 families, and 7 orders. The dominant order was perciformes accounted for 48.4% of the total fishes. Among the appeared 31 species, Nuchequula nuchalis was the dominant species by 52.8%, followed by Pennahia argentata (6.2%), Callionymus valenciennei (5.2%), Thryssa kammalensis (5.1%), Konosirus punctatus (5.0%) acounted for 74.3% of the total fishes. The diversity index was the highest in station 1 (Hʹ=2.512) and lowest in station 2 (Hʹ=1.389). The evenness index was the highest in station 1 (E=0.762) and lowest in station 2 (E=0.421). Furthermore, the dominance index was the highest in station 2 (D=77.0%) and lowest in station 1 (D=41.6%).
