Abstract
The 4 type octagonal dome artificial reef were designed and placed for the enhancement of fish stock. Seasonal changes of the fish gathering were observed at the experimental reef located in Tongyeong marine ranching area from Jan. 2003to April 2004. We identified the total 11-18 fish species by SCUBA diving at each the reef during that period; 18 species in small type, 16 species in medium type, 11 species in large type and 17 species in remodel type, respectively.The number of species showed seasonal variation with the highest number of 5~12 spp. in Summer and the lowest number of 5~8 spp. in Winter. Sebastes inermis, S. schlegeli and Neoditrema ransonneti were found in the reefs all the year round. Beside these, The most fish species such as Pagrus major, Halichoeres poecilopterus, Chromis notatus and Thamnaconus modestus stayed temporarily. In October 2003, the number of Sebastes inermis showed pick with 5 ind./m3 in medium type, 3 ind./m3 in remodel type, 1 ind./m3in small and large type, respectively. In consideration of fish behavior pattern, it was proved that S. inermis and S. schlegeli were successfully adapted to those 4 type octagonal semi-spherical artificial reefs.
