인공어초의 어장환경과 어군 위집에 관한 연구

A Study on the Environment of Fishing ground and luring of Fish schools of Artificial reefs.

The temperature of research area were 8℃~23.5℃ at surface, 7.5℃~19℃ at mid, 7℃~18℃ at lower layer also, the salinity were 31.05‰~32.37‰ at surface, 31.50‰~32.35 at mid, 31.80‰~32.45‰ lower layer respectively. The transparency has been showed 4.5m~7.5m at Ochongdo area, 2.5m~4.3m at Maldo area, 0.8~2.8m at Wido. The conservation condition of artificial fish reefs has been buried at Wido sector a little, but The conservation of condition at Maldo, Ochangdo sector has been showed more efficiently. The appearance species at Ochangdo sector was 20th species, 16th species at Maldo, 15th species at Wido sector respectively also, The appearance species of attached creatures was 19th at Ochangdo, 4th Fisheries botanical species 6th Fisheries animate, 10th at Maldo, 5th Fisheries botanical species 5th Fisheries animate, 8th at Wido, 4 Fisheries botanical species 4 Fisheries animate was appeared.
