The fir st site (K reefs) was located on the seabed off the coast of Ibusuki city in Kagoshima Bay. The site consisted of 37 pine r eefs constructed with black pine Pinus thunbergii which had been damaged by pine bark beetles. The reef adopted a roof type structure with concrete bottom. The second site (I reefs) was located on the seabed off the coast of Izumi city in Yatsushiro Sea. The site consists of 10 pine reefs constructed with loblolly pine Pinus taeda. The reef adopted a cube type structure with concrete bottom. ・・・・ Fish gathering effect was observed by scuba diving on 5 and 23 March, 1 November 1996 for the K reefs, and 23 March 1995, 5 April, 20 November 1996 for the I reefs. The fish gathering effect of the pine reefs were compared with the adjacent concrete reefs. Twenty-four species of fish were found in the K reefs and ten species in the I reefs. Species found in quantity in the K reefs include offshore pony fish L eiognathus rivulatus and crimson sea bream Evynnis japonica. Those found in quantity in the I reefs include crimson sea bream, red sea bream Chrysophrys major and bottom perch A pogon semilineatus. A large gathering of crimson sea bream was observed in the K reefs, whereas there was a large gathering of bottom perch and other large size fishes in the adjacent concrete reefs. On the other hand, the fish gathering effect in the I reefs was similar to that of the adjacent concrete reefs. The comparison of the two sites for a period of about two years after placement shows that both types of artificial pine reefs are highly effective in gathering crimson sea bream and red sea bream. In contrast, the gathering volume of bottom perch in the K reefs was low due to their structure.}, pages = {1--15}, title = {松材漁礁に関する研究-I 初期の集魚効果について}, volume = {18}, year = {1997}, yomi = {ヒゴ, ノビオ} }
