Japanese anchovies are transported to fishing grounds by fishing boats on voyages that can take from 4 to 50 days. \nBecause ammonia excreted by Japanese anchovies might affect their survival during transportation, fishers empirically attempt to maintain them in healthy condition by exchanging water aboard ship holding tanks at a rate of 160–500 % volume h−1. To develop protocols for more efficient and cost-effective transportation of Japanese anchovies, we evaluated their ammonia tolerance and effects of stocking density and variable water  exchange  on  their  survival. We  estimated  median  lethal  concentrations  (with  95  %  confidence intervals) of un-ionized ammonia nitrogen (UIAN), at which 50 % of Japanese anchovies had died within 24 h and 48 h, as 0.770 (0.751–0.790) mg l−1 and 0.706 (0.661–0.750) mg l−1 at 15 °C and 0.634 (0.466–0.802)  mg  l−1  and  0.450  (0.379–0.521)  mg  l−1  at  25  °C,  respectively. While  the  UIAN  concentration increased to lethal levels and severe fish mortality (dependent on stocking density) occurred at 25 °C with no water exchange, the UIAN concentration could be maintained within non-lethal levels at 25 °C and with a one-third water exchange every 12 h. Our results suggest that present-day empirically deduced water exchange rates applied aboard commercial vessels in holding tanks of Japanese anchovies could be reduced, implying a possible cost reduction for the skipjack pole-and-line fisheries"}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"アクオス研究所"}]},"item_3_relation_11":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34394/aquaticanimals.AA2021.0_AA2021-1_1","subitem_relation_type_select":"DOI"}}]},"item_3_relation_13":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_text":"Publisher's Version/PDF (OpenAccess)"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34394/aquaticanimals.AA2021.0_AA2021-1_1","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"アクオス研究所"}],"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://aquaanimal.net/","subitem_relation_type_select":"URI"}}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2434-8643","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Oda, Kentaro"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Hashimoto, Hiroshi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Teruya, Kazuhisa"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Dan, Shigeki"}],"nameIdentifiers":[{},{}]},{"creatorNames":[{"creatorName":"Hamasaki, Katsuyuki"}],"nameIdentifiers":[{},{}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ammonia toxicity","subitem_subject_scheme":"Other"},{"subitem_subject":"median lethal concentration","subitem_subject_scheme":"Other"},{"subitem_subject":"fish culture","subitem_subject_scheme":"Other"},{"subitem_subject":"fish transportation","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article"}]},"item_title":"Ammonia tolerance of Japanese anchovy Engraulis japonicus: Implications for cost reduction in a skipjack pole-and-line fishery","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Ammonia tolerance of Japanese anchovy Engraulis japonicus: Implications for cost reduction in a skipjack pole-and-line fishery"}]},"item_type_id":"3","owner":"15","path":["468","469","471"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-09-21"},"publish_date":"2021-09-21","publish_status":"0","recid":"2211","relation_version_is_last":true,"title":["Ammonia tolerance of Japanese anchovy Engraulis japonicus: Implications for cost reduction in a skipjack pole-and-line fishery"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2023-07-25T10:34:11.214391+00:00"}
