Assessment of attached organisms on a jetty in Yoshimi Bay, western Yamaguchi Prefecture, Japan - Search for juvenile sea cucumber Apostichopus japonicus (stichopodidae) 山口県西部吉見湾の波止場における付着生物の調査 稚ナマコAposichopus japonicusの探索 Yamana, Yusuke 山名, 裕介 ヤマナ, ユウスケ Yamana 山名 ヤマナ Yusuke 裕介 ユウスケ Hamano, Tatsuo 浜野, 龍夫 ハマノ, タツオ Hamano 浜野 ハマノ Tatsuo 龍夫 タツオ Goshima, Seiji 五嶋, 聖治 ゴシマ, セイジ Goshima 五嶋 ゴシマ Seiji 聖治 セイジ open access benthos; distribution; echinoderm fisheries; ecology; growth In order to search for juvenile Apostichopus japonicus, the attached organisms were detached from every 30 cm depth of two steel sheet piles in the framework of a jetty in 3 m depth of water in a shallow harbor area in Yoshimi Bay. A total of 103 species of benthic animals were observed attached to the whole surface of the two steel sheets, and the most numerous 48 species of them were observed in the section of 60-90 cm below the top of the sheet. The total amount of attached organisms was largest in this section, where the oyster Crassostrea gigas was dominant. Two juveniles of A. japonicus of the green colored type were separately collected from the section of 210-240 cm and 240-270 cm, where the bivalve Chama japonica was dominant. They were very hidden in the attached organisms and were considered to belong to 1-year age group settled on the sheet piles. 水産大学校 National Fisheries University 2007-12-25 eng departmental bulletin paper https://fra.repo.nii.ac.jp/records/2011869 fishu_k_56_211 https://agriknowledge.affrc.go.jp/RN/2010761131 agriknowledge AN00124678 0370-9361 水産大学校研究報告 Journal of National Fisheries University 56 2 8 211 218 https://fra.repo.nii.ac.jp/record/2011869/files/fishu_k_56_211.pdf application/pdf 3.5 MB 2024-10-11
