Morphological features during larvae to juveniles were illustrated. Transit from larva to juvenile was occurred on larva attaining about 8.0mm in standard length. Pronounced difference was not observed for the transit phase between the wild and reared specimens. The relationship between standard length and total length for larval and juvenile stages is described by the equation SL=0.726TL+0.827(r=0.997, n=1076). Growth equation of larvae and juveniles during 40 days after hatching is Y=2.629 × e0.0489x, where Y is total length in mm, and X is age in days after hatching. A drastic changes were occurred on morphological characters, development in the external organs such as scales, fins and bands as well as behaviours in swimming and feeding when the larvae transformed from post-larvae to juvenile stage, about 8.0mm SL length. The comprehensive changes of the development in the morphological and behavioural characters were interpreted as indicating the change their life pattern.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"室内飼育して得たマダイ標本を用いて後期仔魚から幼魚までの外部形態の変化を明らかにした。後期仔魚から稚魚への移行は体長約8.0mmまでにほぼ完了する。また稚魚移行期の大きさについては天然魚とほぼ同じと考えられた。ふ化仔魚から全長30mmまでの稚仔魚における全長(TL),標準体長(SL)と前肛門長(AL)の関係は,それぞれ SL=0.726TL+0.827(r=0.997),AL=0.502TL-0.32(r=0.995)で示された。水温17°~24℃で飼育した稚仔魚のふ化から40日間の成長曲線は Y=2.629× e 0.0489x(Y;全長mm,X;ふ化後日数)で表わされ,日成長率は約5%であった。全長に対する前肛門長比は 全長8.0mm前後までは大きく変化し,それ以後は約50%で一定した値を示した。この比成長の屈折点は,稚仔魚の生理的および形態的な発育段階の変化と符合するだけでなく,生活様式の移り変りをよく反映していると考えられる。","subitem_description_language":"ja","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"南西海区水産研究所","subitem_publisher_language":"ja"},{"subitem_publisher":"Nansei Regional Fisheries Research Laboratory","subitem_publisher_language":"en"}]},"item_10002_radio_30":{"attribute_name":"item_10002_radio_30","attribute_value_mlt":[{"subitem_radio_item":"吉田","subitem_radio_language":"ja"}]},"item_10002_relation_16":{"attribute_name":"情報源","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"nnf_k_16_85","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/2010283649","subitem_relation_type_select":"URI"}}]},"item_10002_source_id_11":{"attribute_name":"item_10002_source_id_11","attribute_value_mlt":[{"subitem_source_identifier":"AN00181988","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"item_10002_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"0388-841X","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":"Fukuhara, Osamu","creatorNameLang":"en","creatorNameType":"Personal"},{"creatorName":"福原, 修","creatorNameLang":"ja","creatorNameType":"Personal"},{"creatorName":"フクハラ, オサム","creatorNameLang":"ja-Kana","creatorNameType":"Personal"}],"familyNames":[{"familyName":"Fukuhara","familyNameLang":"en"},{"familyName":"福原","familyNameLang":"ja"},{"familyName":"フクハラ","familyNameLang":"ja-Kana"}],"givenNames":[{"givenName":"Osamu","givenNameLang":"en"},{"givenName":"修","givenNameLang":"ja"},{"givenName":"オサム","givenNameLang":"ja-Kana"}],"nameIdentifiers":[{"nameIdentifier":"3345","nameIdentifierScheme":"WEKO"}]}]},"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":"マダイ稚仔魚の形態学的研究(4)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"マダイ稚仔魚の形態学的研究(4)","subitem_title_language":"ja"},{"subitem_title":"Morphological Studies of Larva of Red Sea Bream-IV.
