In Hokkaido strain 11 out of 329 precocious male became smolt, but no smolt was found in 5 precocious male from desmolt. No smolt appeared in 283 precocious male and in 28 precocious male from desmolt in Koide strain. The difference in mean body length between smolt and parr within the same group of precocious male was little, but the variance of the latter in body length was about twice as large as that of the former. This suggests that the body length has some influence on smoltification of precocious male. Mean condition factor of smolts from precocious male in Hokkaido-Nikko and Hokkaido strain were 12.19 and 12.06 respectively. On the other hand the means of parr from the same group were 14.09 and 14.18 respectively. The frequency distributions of condition factor in smolt and parr partially overlapped each other, but the differences in the means between smolt and parr were significant at 1% level. These values for smolt from precocious male were large as compared with the values of smolt from 0 age parr which were 11.30 and 11.49. In the artificial seawater challenge test 3 out of 18 smolt from precocious male and 8 out of 20 smolt from 0 age parr survived for 1 week. Survival rate of the former was lower than that of the latter, but these were extremely poor in both cases. The cause is indistinct, but survived fish seemed to have a certain seawater adaptability.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"養殖研究所","subitem_publisher_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nria_k_8_15","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/2010322106","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00245945","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0389-5858","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":"佐藤, 良三","creatorNameLang":"ja"}],"familyNames":[{"familyName":"佐藤","familyNameLang":"ja"}],"givenNames":[{"givenName":"良三","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"福田, 善三","creatorNameLang":"ja"}],"familyNames":[{"familyName":"福田","familyNameLang":"ja"}],"givenNames":[{"givenName":"善三","givenNameLang":"ja"}]},{"creatorNames":[{"creatorName":"阿久津, 梅二","creatorNameLang":"ja"}],"familyNames":[{"familyName":"阿久津","familyNameLang":"ja"}],"givenNames":[{"givenName":"梅二","givenNameLang":"ja"}]}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"smolt; precocious male; masu salmon","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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":"サクラマス0年魚成熟雄群から生じた1年魚スモルト","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"サクラマス0年魚成熟雄群から生じた1年魚スモルト","subitem_title_language":"ja"},{"subitem_title":"Yearling smolt from precocious male masu salmon, Oncorhynchus masou.","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716955633551"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-18"},"publish_date":"2024-06-18","publish_status":"0","recid":"2007545","relation_version_is_last":true,"title":["サクラマス0年魚成熟雄群から生じた1年魚スモルト"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-03-28T07:59:09.109771+00:00"}
