Despite the long term effort of artificially produced abalone seed transplantation in Japan, recent annual catches of abalone have declined from 5,000 tons level to 3,000 tons. This marked decline of the annual catch has occurred from 1980 when the intensive transplantation of seed abalone has been increasingly undertaken throughout Japan. Consequently it has become clear that seed transplantation dose not contribute to the enhancement of the natural abalone resources. However, the transplantation of these seed abalone were not designed to recruit to the natural population. Rather these attempts have been to promote the fishing grounds utilization for the one generation of the seed abalone that were released. Subsequently the research effort on the influence of transplantations on the natural population or on its abundance has not been marked. Although recaptures have brought a faintly profitable turnover in the case when larger size seed of more than 3 cm in shell length were transplanted, the wild population did not increase. Based on new information on the ecological role of the algal community within the rocky reef ecosystem, a theoretical approach to the ecological management and utilization of seed transplantation aimed at an establishment of self sustainable natural spawner population are discussed in order restore natural abalone populations.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Tohoku National Fisheries Researh Institute","subitem_publisher_language":"en"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"tnf_k_60_23","subitem_relation_type_select":"Local"}}]},"item_10002_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"ja","subitem_relation_name_text":"日本農学文献記事索引(agriknowledge)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://agriknowledge.affrc.go.jp/RN/2010571889","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00167637","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0049-402X","subitem_source_identifier_type":"PISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"東北区水産研究所","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Seki, Tetsuo","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"關, 哲夫","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"セキ, テツオ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Seki","familyNameLang":"en"},{"familyName":"關","familyNameLang":"ja"},{"familyName":"セキ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tetsuo","givenNameLang":"en"},{"givenName":"哲夫","givenNameLang":"ja"},{"givenName":"テツオ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3597","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"東北大学","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Sano, Minoru","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"佐野, 稔","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"サノ, ミノル","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Sano","familyNameLang":"en"},{"familyName":"佐野","familyNameLang":"ja"},{"familyName":"サノ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Minoru","givenNameLang":"en"},{"givenName":"稔","givenNameLang":"ja"},{"givenName":"ミノル","givenNameLang":"ja-Kana"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"エゾアワビ資源管理の考え方","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"エゾアワビ資源管理の考え方","subitem_title_language":"ja"}]},"item_type_id":"10002","owner":"10","path":["1716950799012"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-10"},"publish_date":"2024-06-10","publish_status":"0","recid":"2007437","relation_version_is_last":true,"title":["エゾアワビ資源管理の考え方"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-05-29T02:25:40.409126+00:00"}
