As the large-sized saury, two body length classes of 290 to 299mm and 300 to 309mm were conducted. The coefficient of fatness was made no distinction between male and female. The gonad weights of males distributed mainly less than 2.0g and no appreciable difference between the both waters. On the females, they distributed mainly in the range from 0.5 to 0.6g in the middle-southern waters of Kuril Islands, while in the eastern waters of Hokkaido, they distributed mainly in the range from 0.3 to 0.4g. The coefficients of fatness distributed around 5.0 in the middle-southern waters of Kuril Islands, while in the eastern waters of Hokkaido, they distributed mainly in the range from 4.0 to 5.0, which were smaller than the former by over 0.5. The relationship between the gonad weight and the coefficient of fatness were different between the both waters even when the fishing ground shifted from the middle-southern waters of Kuril Islands to the eastern waters of Hokkaido, and no correlation was found between the gonad weight and the coefficient of fatness. It was considerd that the process of change of the gonad weight between the middle-southern waters of Kuril Islands and the waters of Hokkaido did not correspond to the process of change, as known generally, with the change of seasons or the southward movement of the fishing ground. The distributions of the gonad weight and the coefficient of fatness were considered to be stable in the eastern waters of Hokkaido. From these considerations, the process of change of the gonad weight and the coefficient of fatness of the large-sized saury and its southward migration were estimated to be discontinuous between the both waters.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1) 1978~1980年の3ヶ年について、サンマの大型魚群を対象に,中·南部千島水域と道東水域の間で,生殖腺重量と肥満度の分布および両者の関係について比較を試みた。2) 資料は8月下旬から10月上旬の間に漁獲された漁獲物標本の測定結果に基づき,旬別,水域別に検討した。3) 生殖腺重量と肥満度の関係を検討し,以後の解析では大型魚群として290~299,300~309mmの2つの体長階級をあわせてとりあつかった。また肥満度は雌雄を区別しなかった。4) 生殖腺重量は,雄では水域間で差がみられず,0.2g未満の個体が主体であった。雌は,中·南部千島水域では 0.5~0.6g,道東水域では0.3~0.4gが主体であった。5) 肥満度は,中·南部千島水域では5.0を中心とした分布を示したが、道東水域では大部分の個体は4.0~5.0の範囲にあり,約0.5以上低かった。6) 中·南部千島水域と道東水域の間での生殖腺重量と肥満度の関係は,両水域間で漁場の交代が行なわれた時点で,すでに明らかに異なっていた。また両水域とも両者の間に一定の相関関係は認められなかった。7) 中·南部千島水域と道東水域の間では,生殖腺重量の変化の過程が,これまでに知られている季節的あるいは漁場の南下に伴なう変動の過程と一致しないこと,道東水域では,生殖腺重量と肥満度の分布は,中·南部千島水域とは明らかな相異を持って安定していると考えられることから,両水域間では,サンマの大型魚群の生殖腺重量と肥満度の変化の過程は不連続で,その移動においても直接的な関係ではないと考えられた。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"北海道区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Hokkaido 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":"hnf_k_46_7","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/2010234281","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":"AN00124758","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0513-2541","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":[{"creatorNames":[{"creatorName":"和田, 時夫","creatorNameLang":"ja"},{"creatorName":"ワダ, トキオ","creatorNameLang":"ja-Kana"},{"creatorName":"Wada, Tokio","creatorNameLang":"en"}],"familyNames":[{"familyName":"和田","familyNameLang":"ja"},{"familyName":"ワダ","familyNameLang":"ja-Kana"},{"familyName":"Wada","familyNameLang":"en"}],"givenNames":[{"givenName":"時夫","givenNameLang":"ja"},{"givenName":"トキオ","givenNameLang":"ja-Kana"},{"givenName":"Tokio","givenNameLang":"en"}]}]},"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":"南下回遊初期におけるサンマ大型魚群の生殖腺重量と肥満度","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"南下回遊初期におけるサンマ大型魚群の生殖腺重量と肥満度","subitem_title_language":"ja"},{"subitem_title":"Gonad Weight and Coefficient of Fatness of the Large-sized Saury on Early Period of the South-ward Migration.","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716950587014"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-08"},"publish_date":"2024-04-08","publish_status":"0","recid":"2001770","relation_version_is_last":true,"title":["南下回遊初期におけるサンマ大型魚群の生殖腺重量と肥満度"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-01-21T04:58:32.160757+00:00"}
