The stomach contents consisted almost entirely of the pelagic and mesopelagic fishes including squids, viz. Japanese anchovy Engraulis japonica, sardine Sardinops melanostictus, sand lance Ammodytes personatus, Atlantic cutlassfish Trichiurus lepturus and Japanese common squid Todarodes pacificus. The seasonal and regional differences in diet composition reflected well the changes of food in the environment. In the adult, the monthly averages of reconstructed stomach contents weight per predator weight indicated two peaks, April and during a period from July to August, which corresponded to the pre- and postspawning periods, respectively. The feeding intensity of young was also high in the growing season. In most months the percentage of large prey increased with the increase of body length of the predator.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"1981年5月から1984年6月までの間に瀬戸内海中西部域で漁獲されたサワラ714尾の胃内容物を調査し,以下の知見を得た。1. 産卵期の前後である4月及び7月の一部と8月には,親魚群の摂餌活動が活発化する。2. 未成魚群の成長期にも摂餌活動が活発な傾向がうかがえた。3. 全体をとおしての主な餌生物は,カタクチイワシ,マイワシ,イカナゴ,タチウオ,マルアジ,スルメイカなど,表·中層性の動物であった。4. 餌組成は,季節·海域によって差異がみられた。5. 捕食者が大きくなると,大型の餌の比率が増加する傾向がみられた。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei Regional Fisheries Research Laboratory","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":"nnf_k_20_73","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/2010343552","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","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":"Kishida, Tatsu","creatorNameLang":"en"},{"creatorName":"岸田, 達","creatorNameLang":"ja"},{"creatorName":"キシダ, タツ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Kishida","familyNameLang":"en"},{"familyName":"岸田","familyNameLang":"ja"},{"familyName":"キシダ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Tatsu","givenNameLang":"en"},{"givenName":"達","givenNameLang":"ja"},{"givenName":"タツ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"476","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"10416034","nameIdentifierScheme":"e-Rad_Researcher","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=10416034"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"瀬戸内海中西部域におけるサワラの食性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"瀬戸内海中西部域におけるサワラの食性","subitem_title_language":"ja"},{"subitem_title":"Feeding Habits of Japanese Spanish Mackerel in the Central and Western Waters of the Seto Inland Sea","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-25"},"publish_date":"2024-04-25","publish_status":"0","recid":"2003255","relation_version_is_last":true,"title":["瀬戸内海中西部域におけるサワラの食性"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-17T04:50:01.903478+00:00"}
