Phytoplanktonic food abundance was studied to determine the feeding characteristics of Japanese sardine with respect to the size composition. In spring bloom larger fractions than 95μm dominated. After the spring bloom the chlorophyll a standing stock decreased sharply and larger fractions of phytoplankton assemblages diminished in the offshore Oyashio region. In contrast, a prolonged bloom with larger fractions was recognized at the station on the continental shelf until autumn. But results of a tentative calculation suggest that the aquired energy would be less than the energy requirement of the sardine if the sardine feed only on phytoplankton, even in the continental shelf area. Consequently, Japanese sardine appears not to depend predominantly on phytoplankton.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"北海道南東海域の植物性餌料,すなわち餌料としての植物プランクトン分布を明らかにするため,1987年から1989年にかけてクロロフィルa分布調査を行った.その結果からサイズ組成を基に植物性餌料分布について検討し,沖合域では浮魚の索餌期にあたる夏季に植物性餌料はほとんどないこと,これに対して沿岸陸棚域では春季ブルーミングの後,秋季まで大型の画分を含んだ比較的高濃度のクロロフィルaが存在し沖合域よりは植物性餌料は豊富であることが明らかになった.しかし,マイワシが植物プランクトンだけを利用する場合のエネルギー量を試算した結果は,必要エネルギー量に比較して十分とはいえないことから,マイワシは植物プランクトンには多くを依存していないことが予想された.","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 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":"hnf_k_55_13","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/2010501385","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":"AN1015410X","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":"荻島, 隆","creatorNameLang":"ja"},{"creatorName":"オギシマ, タカシ","creatorNameLang":"ja-Kana"},{"creatorName":"Ogishima, Takashi","creatorNameLang":"en"}],"familyNames":[{"familyName":"荻島","familyNameLang":"ja"},{"familyName":"オギシマ","familyNameLang":"ja-Kana"},{"familyName":"Ogishima","familyNameLang":"en"}],"givenNames":[{"givenName":"隆","givenNameLang":"ja"},{"givenName":"タカシ","givenNameLang":"ja-Kana"},{"givenName":"Takashi","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":"北海道南東海域におけるマイワシ餌料としてのクロロフィル α 分布","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"北海道南東海域におけるマイワシ餌料としてのクロロフィル α 分布","subitem_title_language":"ja"},{"subitem_title":"Distribution of chlorophyll α as a phytoplanktonic food for Japanese sardine in the sea area off southeast Hokkaido","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":"2001709","relation_version_is_last":true,"title":["北海道南東海域におけるマイワシ餌料としてのクロロフィル α 分布"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-01-20T04:46:45.447977+00:00"}
