MTD nets were also towed to evaluate its vertical distribution pattern in June, September, and December 1986. The results of Norpac nets indicated that the occurrence of eggs and larvae were from mid-February through late June. After a rapid growth (3.1mm/month) of the larvae and early postlarvae, the modal size (~10mm) of postlarvae remained unchanged from summer to winter, indicating no growth of E. pacifica during this season. The results of MTD nets revealed a diurnal migration pattern of E. pacifica in the order of 300m in June and December. However, in September, the magnitude of night ascent was reduced because of a higher water temperature barrier (>20℃) developed in the euphotic zone. This limited night ascent should have reduced feeding of this species in the euphotic zone and considered to be the major cause for its growth stagnation in Toyama Bay. After this long growth stagnation from summer to winter, E. pacifica grew rapidly once again through the spring phytoplankton bloom of the next year and spawned. In Toyama Bay E. pacifica was considered to have only one generation per year. The minimum maturity size and the maximum size were 11mm and 22mm, respectively, for males and were 12mm and 23mm, respectively, for females. The estimated life span was less than 21 months. The present results are compared with those for other regions of the North Pacific.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"日本海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Japan Sea 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":"js_k_43_69_81","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/2010501890","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":"AN00186380","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0021-4620","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":[{"affiliationNameIdentifiers":[],"affiliationNames":[{"affiliationName":"","affiliationNameLang":"ja"}]}],"creatorNames":[{"creatorName":"Iguchi, Naoki","creatorNameLang":"en"},{"creatorName":"井口, 直樹","creatorNameLang":"ja"},{"creatorName":"イグチ, ナオキ","creatorNameLang":"ja-Kana"}],"familyNames":[{"familyName":"Iguchi","familyNameLang":"en"},{"familyName":"井口","familyNameLang":"ja"},{"familyName":"イグチ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Naoki","givenNameLang":"en"},{"givenName":"直樹","givenNameLang":"ja"},{"givenName":"ナオキ","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"544","nameIdentifierScheme":"WEKO"},{"nameIdentifier":"00371899","nameIdentifierScheme":"e-Rad","nameIdentifierURI":"https://kaken.nii.ac.jp/ja/search/?qm=00371899"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"日本海区水産研究所","affiliationNameLang":"ja"},{"affiliationName":"ニホンカイクスイサンケンキュウジョ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Japan Sea National Fisheries Research Institute","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"池田, 勉","creatorNameLang":"ja"},{"creatorName":"イケダ, ツトム","creatorNameLang":"ja-Kana"},{"creatorName":"Ikeda, Tsutomu","creatorNameLang":"en"}],"familyNames":[{"familyName":"池田","familyNameLang":"ja"},{"familyName":"イケダ","familyNameLang":"ja-Kana"},{"familyName":"Ikeda","familyNameLang":"en"}],"givenNames":[{"givenName":"勉","givenNameLang":"ja"},{"givenName":"ツトム","givenNameLang":"ja-Kana"},{"givenName":"Tsutomu","givenNameLang":"en"}]},{"creatorAffiliations":[{"affiliationNames":[{"affiliationName":"富山県水産試験場","affiliationNameLang":"ja"},{"affiliationName":"トヤマケンスイサンシケンジョウ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Toyama Prefectural Fisheries Experiment Station","affiliationNameLang":"en"}]},{"affiliationNames":[{"affiliationName":"富山県沿岸漁業振興公社","affiliationNameLang":"ja"},{"affiliationName":"トヤマケンエンガンギョギョウシンコウコウシャ","affiliationNameLang":"ja-Kana"},{"affiliationName":"Toyama Prefectural Fish-Farming Center","affiliationNameLang":"en"}]}],"creatorNames":[{"creatorName":"今村, 明","creatorNameLang":"ja"},{"creatorName":"イマムラ, アキラ","creatorNameLang":"ja-Kana"},{"creatorName":"Imamura, Akira","creatorNameLang":"en"}],"familyNames":[{"familyName":"今村","familyNameLang":"ja"},{"familyName":"イマムラ","familyNameLang":"ja-Kana"},{"familyName":"Imamura","familyNameLang":"en"}],"givenNames":[{"givenName":"明","givenNameLang":"ja"},{"givenName":"アキラ","givenNameLang":"ja-Kana"},{"givenName":"Akira","givenNameLang":"en"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Euphausia pacifica;
