Intrusion of low-salinity (< 33) water was observed in July 1985-1987. The low-salinity water was thought to intrude near the coast of Shimonoseki through the Tsushima Strait from the East China Sea. Salinity decreased suddenly in a short period of about ten days. The decrease of salinity in 1985 and 1986 was probably attributed to the Ekman transport due to the blowing of southwesterly winds. After the intrusion of low-salinity water occurred, the sardine catch suddenly increased, while the anchovy one decreased. Not only hydrographic condition but also the fishing condition changed largely through the intrusion of low-salinity water.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"本研究から得られた主な知見は次のとおりである.1) 1985~1987年の3カ年とも7月に塩分33以下の低塩水の流入がみられた. この低塩水は東シナ海から対馬海峡を経由して下関市沿岸に流入したと考えられた.2) 低塩化はごく短期間(数日~10日程度)のうちに急激に進行した. この現象は周辺海域の流れや水温変動と連動するかなり大きな空間スケールのものと考えられた. 1985,1986年に観測された低塩化現象は,南西風の連吹に伴うエクマン輸送に起因したものと考えられた.3) 下関市沿岸で操業する棒受網漁船の漁獲物が,塩分急低下を境にカタクチイワシからマイワシへと明瞭に変化した.このことは,低塩水流入に伴う水塊の交替がイワシ類の漁場形成に影響を及ぼすことを示しており,低塩水流入を境に海況だけでなく漁況も大きく変動することが明らかになった.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Seikai National Fisheries Research Institute","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"snf_k_74_35","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/2010550453","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00393385","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0582-415X","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":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Katoh, Osamu","creatorNameLang":"en"},{"creatorName":"加藤, 修","creatorNameLang":"ja"},{"creatorName":"カトウ, オサム","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Katoh","familyNameLang":"en"},{"familyName":"加藤","familyNameLang":"ja"},{"familyName":"カトウ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Osamu","givenNameLang":"en"},{"givenName":"修","givenNameLang":"ja"},{"givenName":"オサム","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"465","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70371896","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70371896"}]},{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifierScheme":"ISNI","affiliationNameIdentifierURI":"https://isni.org/isni/"}],"affiliationNames":[{"affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Hayashi, Kohachi","creatorNameLang":"en"},{"creatorName":"林, 小八","creatorNameLang":"ja"},{"creatorName":"ハヤシ, コハチ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Hayashi","familyNameLang":"en"},{"familyName":"林","familyNameLang":"ja"},{"familyName":"ハヤシ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Kohachi","givenNameLang":"en"},{"givenName":"小八","givenNameLang":"ja"},{"givenName":"コハチ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3429","nameIdentifierScheme":"WEKO"}]}]},"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":"響灘における低塩水流入に伴う漁海況変動","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"響灘における低塩水流入に伴う漁海況変動","subitem_title_language":"ja"},{"subitem_title":"hanges of Hydrographic and fishing conditions correlated with intrusion of low-salinity water in the Hibiki-Nada","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205967"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-20"},"publish_date":"2024-06-20","publish_status":"0","recid":"2008151","relation_version_is_last":true,"title":["響灘における低塩水流入に伴う漁海況変動"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-06-05T04:30:34.120007+00:00"}
