Three factors varied with age, season and sex. The condition factor stayed level fairly from 5 to 15 cm body length, rose in medium sized fish between 20 and 30 cm and reached a maximum for adult fish over 30 cm in length. The gutted condition factor showed little change with size for fish longer than 5 cm; however it fluctuated seasonally in adult fish. Relative liver weight differed with sex; females had heavier livers than males of the same size. All three factors rose in August and September and declined from January to May. In adults sexual maturation appeared to effect the seasonal fluctuations. Condition factor and gutted condition factor were higher in males than in females. Condition factors showed some geographical variation; e.g. low values in the Japan Sea samples and in spent fish from the Kamchatka area. But these data are not sufficient to clarify the whole picture of geographical variation. It is necessary to take into account the effects of the yearly sexual cycle when assessing geographical variation.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"スケトウダラの肥満度·肝臓重量比について,生長による変化,季節的変化,雌雄差および漁場間の比較をおこなった.1. 体長5~15cmの間の全肥満度はほとんど変りなく,20cm付近と30cm付近からいくらか高くなり,30cm以上ではほば一定である.肉肥満度は体長による差はほとんどない.成魚の肝臓重量比は季節的変化が大きく,未成魚より高い時期と差のない時期がある.2. 全肥満度·肉肥満度·肝臓重量比は8~9月に高く,1~5月に低下するが,成魚は産卵前期から産卵直後にかけて大きく変化する、成魚の全肥満度·肉肥満度は雌より雄の値が高く,肝臓重量比は雄より雌の値が高い.3. 日本海の雌の肥満度は他漁場に比べて低く,カムチャッカ半島周辺の産卵後のものは三陸沿岩および襟裳岬以西海域よりも低い.しかし,本種の肥満度は季節的変化が大きく,漁場間の比較には生活年周期を考慮する必要があるが,それにしても漁場間の差が明瞭でない場合が多い。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東北区水産研究所","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_38_1","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/2010170639","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":"AN00167637","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","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":[{"creatorNames":[{"creatorName":"Koyachi, Sakae","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"小谷地, 栄","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"コヤチ, サカエ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Koyachi","familyNameLang":"en"},{"familyName":"小谷地","familyNameLang":"ja"},{"familyName":"コヤチ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Sakae","givenNameLang":"en"},{"givenName":"栄","givenNameLang":"ja"},{"givenName":"サカエ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3545","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hashimoto, Ryohei","creatorNameLang":"en","creatorNameType":"Organizational"},{"creatorName":"橋本, 良平","creatorNameLang":"ja","creatorNameType":"Organizational"},{"creatorName":"ハシモト, リョウヘイ","creatorNameLang":"ja-Kana","creatorNameType":"Organizational"}],"familyNames":[{"familyName":"Hashimoto","familyNameLang":"en"},{"familyName":"橋本","familyNameLang":"ja"},{"familyName":"ハシモト","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Ryohei","givenNameLang":"en"},{"givenName":"良平","givenNameLang":"ja"},{"givenName":"リョウヘイ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3544","nameIdentifierScheme":"WEKO"}]}]},"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":"スケトウダラの肥満度・肝臓重量比について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"スケトウダラの肥満度・肝臓重量比について","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":"2007242","relation_version_is_last":true,"title":["スケトウダラの肥満度・肝臓重量比について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-06-30T07:13:39.712711+00:00"}
