Catches fluctuate in relation to not only the stock level, but also hydrographic conditions such as warm and cold water regions appearing in the temperature distributions at 50m depth. The multiple regrresion equation of catches (Y) is as follows: Y =- 65.96+136.18X1-10.16X3+11.81X4 Where, X1, X3, and X4 show stock level, east/westward fluctuation of cold water regions (E/WFCR), and north/southward fluctuation of warm water regions (N/SFWR), respectively. The effects of N/SFWR and E/WFCR on fluctuation in catches are considered as a supplying mechanism of school and wall effects for local fishing ground formation.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"日本海の佐渡島周辺海域におけるスルメイカ北上期の漁獲量の経年変動に果たす海況要因の役割を明らかにするために,1980~1991年の日本海スルメイカの資源量指数と50m深における暖·冷水域の分布状況を説明変数とした重回帰解析を行い以下の結果を得た.(1) 北上期漁獲量の経年変動は,資源量指数単独の場合より海況変動要因を加えた方がよく説明され,漁獲量変動に果たす暖水域の動向と冷水域の接岸状況の重要性が確認された.(2) 北上期漁獲量変動(Y)は,資源量指数変動(X1),冷水域の東西方向の変動(X3),暖水域の南北方向の変動(X4)に対して最も重相関関係が高く(r=0.93),次式のような重回帰式が得られた. Y =- 36.96+136.18X1-10.16X3+11.81X4 (3) 回帰式に用いた2つの海況要因のうち,能登半島から佐渡島周辺海域に及ぶ暖水域の北上は,スルメイカ魚群の補給機構,佐渡島付近への冷水域の接岸は魚群を滞留させる障壁効果に関わる海況要因であると評価することができる.","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea National Fisheries Research 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":"js_k_43_83_92","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/2010501891","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","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":"新潟県水産試験場","affiliationNameLang":"ja"},{"affiliationName":"ニイガタケンスイサンシケンジョウ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Niigata Prefectural Fisheries Experimental Station","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"河村, 智志","creatorNameLang":"ja"},{"creatorName":"カワムラ, サトシ","creatorNameLang":"ja-Kana"},{"creatorName":"Kawamura, Satoshi","creatorNameLang":"en"}],"familyNames":[{"familyName":"河村","familyNameLang":"ja"},{"familyName":"カワムラ","familyNameLang":"ja-Kana"},{"familyName":"Kawamura","familyNameLang":"en"}],"givenNames":[{"givenName":"智志","givenNameLang":"ja"},{"givenName":"サトシ","givenNameLang":"ja-Kana"},{"givenName":"Satoshi","givenNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"日本海区水産研究所","affiliationNameLang":"ja"},{"affiliationName":"ニホンカイクスイサンケンキュウジョ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Japan Sea National Fisheries Research Institute","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"Hirai, Mitsuyuki","creatorNameLang":"en"},{"creatorName":"平井, 光行","creatorNameLang":"ja"},{"creatorName":"ヒライ, ミツユキ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Hirai","familyNameLang":"en"},{"familyName":"平井","familyNameLang":"ja"},{"familyName":"ヒライ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Mitsuyuki","givenNameLang":"en"},{"givenName":"光行","givenNameLang":"ja"},{"givenName":"ミツユキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"1989","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"70371789","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=70371789"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"catch fluctuation; fishing ground; hydrographic condition; migration; squid","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"佐渡島周辺海域における北上期スルメイカの漁獲量変動に果たす海況変動の役割","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"佐渡島周辺海域における北上期スルメイカの漁獲量変動に果たす海況変動の役割","subitem_title_language":"ja"},{"subitem_title":"Evaluation of Hydrographic Conditions on the Fluctuation in Catches of Common Squid during Period of Northward Migration in the Waters around Sado Island in the Japan Sea","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951426151"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-23"},"publish_date":"2024-04-23","publish_status":"0","recid":"2002468","relation_version_is_last":true,"title":["佐渡島周辺海域における北上期スルメイカの漁獲量変動に果たす海況変動の役割"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-02-13T05:24:24.770762+00:00"}
