In all of the western and central North Pacific and Gulf of Alaska, the macrozooplankton biomass in these winter months was much lower than that in summer months. Salmonids (Oncorhynchus spp.) were captured in waters with low sea surface temperatures (<8 °C), where the macrozooplankton biomass remained quite low as well. The salmonids may have a survival strategy to stay in cold waters in order to reduce their energetic consumption, because macrozooplankton as prey is not abundantly available in winter. The cold-water environment appears to be advantageous to the survival of offshore salmonids overwintering under poor food conditions.","subitem_description_language":"en"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"遠洋水産研究所"}]},"item_1617186702042":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_1617186920753":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"0386-7285","subitem_source_identifier_type":"ISSN"},{"subitem_source_identifier":"AN00025949","subitem_source_identifier_type":"NCID"}]},"item_1617187024783":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"69"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueDates":{"bibliographicIssueDate":"1999-03","bibliographicIssueDateType":"Issued"},"bibliographicPageEnd":"75","bibliographicPageStart":"69","bibliographicVolumeNumber":"36","bibliographic_titles":[{"bibliographic_title":"遠洋水産研究所研究報告"},{"bibliographic_title":"遠洋水産研究所研究報告"}]}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_1617353299429":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"http://rms1.agsearch.agropedia.affrc.go.jp/contents/library/jnr/enyo.html","subitem_relation_type_select":"URI"}}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2023-03-18"}],"displaytype":"simple","filename":"BullNatResInstFarSeasFish_36_69.pdf","filesize":[{"value":"511.7 KB"}],"mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://hiroshima.repo.nii.ac.jp/record/2009306/files/BullNatResInstFarSeasFish_36_69.pdf"},"version_id":"638770d7-6c75-4b85-91f0-bf690dba1669"}]},"item_1732771732025":{"attribute_name":"旧ID","attribute_value":"30215"},"item_title":"冬季の北太平洋亜寒帯水域にさけ・ます類の餌は豊富にあるのか?","item_type_id":"40003","owner":"41","path":["1730444907710"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2023-03-18"},"publish_date":"2023-03-18","publish_status":"0","recid":"2009306","relation_version_is_last":true,"title":["冬季の北太平洋亜寒帯水域にさけ・ます類の餌は豊富にあるのか?"],"weko_creator_id":"41","weko_shared_id":-1},"updated":"2025-02-22T05:19:51.468499+00:00"}
