영문 초록

To comparison of species composition of fish between the artificial reefs and non-artificial reefs in coastal waters off Gangneung. We set the fish trammel nets and pot nets. During the studying period, In the artificial reefs, a total of 452 fishes were sampled and classified into 38 species, 8 families, and 23 orders, the dominant species were Hexagrammos otakii (10.0%), Ditrema temminckii (7.3%), H. agrammus (7.1%), Sebastes schlegelii (6.7%), Neoditrema ransonnetii (5.5%). While in the non-artificial reefs, a total of 233 fishes 32 species representing 7 families in 19 orders were collected. In the nonartificial reefs dominant species were Glyptocephalus stelleri (12.0%), Pleuronectes herzensteini (10.7%), Kareius bicoloratus (9.9%), Hippoglossoides pinetorum (8.6%), Pleuronectes punctatissima (7.7%). In the artificial reefs, the dominance index was the highest in February (D=0.33), the lowest August (D=0.16) and November (D=0.16). The dominance index of the non-artificial reefs was the highest in February (D=0.29) and the lowest in August (D=0.20).
