The set-net fisheries yield good catches of juvenile bluefin when warm waters form a migration route which guides the temperate/subtropical fish to coastal waters. In summer, the higher the water temperatures in the fishing grounds become, the earlier the fish migrate north and the earlier a peak catch occurs. The First Oyashio Intrusion is an important hydrographic condition governing not only the distribution pattern of warm waters which form the migration route but temperatures in fishing grounds. Available data also reveal that a conspicuous stepwise decline in the adult bluefin catch coincided with a change from positive (northward) to negative (southward) progression years in the long-term linear trend of interannual variations in location of the First Oyashio Intrusion.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"三陸沿岸定置網のクロマグロ漁況が,海況によって主に支配される魚群の補給過程の変動にどのように影響されるかを明らかにすることを目的として,(1)1966-1987年の海洋観測資料に基づき,三陸近海の海況条件をクロマグロ漁況との関連で解析し,(2)温帯性クロマグロが好適とする暖水帯の三陸近海での形成のされ方一海況のパターンーによって回遊·補給経路及び沿岸定置網漁場への補給量が決定されていること,(3)海況パターンを決定する上でも,またクロマグロ漁況の長期変動に密接に関わっているという点でも親潮第一貫入の変動がとりわけ重要な役割を果していることを示した.","subitem_description_language":"ja","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 Regional Fisheries Research Laboratory","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_51_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/2010430700","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":"Ogawa, Yoshihiko","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"小川, 嘉彦","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"オガワ, ヨシヒコ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Ogawa","familyNameLang":"en"},{"familyName":"小川","familyNameLang":"ja"},{"familyName":"オガワ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Yoshihiko","givenNameLang":"en"},{"givenName":"嘉彦","givenNameLang":"ja"},{"givenName":"ヨシヒコ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3587","nameIdentifierScheme":"WEKO"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"岩手県水産試験場","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Ishida, Tomoko","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"石田, 知子","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"イシダ, トモコ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Ishida","familyNameLang":"en"},{"familyName":"石田","familyNameLang":"ja"},{"familyName":"イシダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tomoko","givenNameLang":"en"},{"givenName":"知子","givenNameLang":"ja"},{"givenName":"トモコ","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":"三陸沿岸クロマグロ漁況に関与する海況条件","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"三陸沿岸クロマグロ漁況に関与する海況条件","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":"2007355","relation_version_is_last":true,"title":["三陸沿岸クロマグロ漁況に関与する海況条件"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-05-27T06:26:45.501851+00:00"}
