The effects of starvation on general activity of the larvae are also studies. Fertilized eggs were obtained from parent fishes held in a concrete aquarium. Hatched larvae were reared in 30L container. The experimental larvae were divided into 7 groups. The first was starved to death. The second was fed immediately after mouth opening (control). The remaining 5 groups were starved for 1-5 days after mouth opening. The feeding schedule for these larvae was shown in Table 1. The results obtained may be summerized as follows. 1) The newly hatched larvae survived for 8 days without food at temperature of 19.4-22.4°c. The growth of the starved larvae was observed only in the initial 4 days while some of the yolk and/or oil globule were still remained. 2) The initial starvation from mouth opening had considerable ill effects depending on the number of days of starvation on growth, development and survival of the larvae for the succeeding 15 days, but thereafter the 1- and 2-day-starved larvae showed a gradual recovery from these effects, and developed as far as in the control in size and morphogenesis at the end of experiment, 36 days after hatching. 3) Suitable food must be provided within 2 days at least after mouth opening, in order to achieve high survival rates. 4) Immediate feeding after mouth opening maintained a high survival rate during the first 2 weeks, but thereafter mortality rate became higher and the over all survival rate at the end of 36 day's experiment was by no means better than among the larvae starved for up to 2 days after mouth opening. It may be inferred, therefore, that the newly hatched larvae may contain some of the genetical mortals and the initial 2-day-starvation may have a selective effect of the larvae fitted for artificial rearing.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"初期の無給餌がマダイ仔魚の歩留り,成長,発育に及ばす影響と初期給餌開始日を仔魚の歩留り,成長,発育の面から検討した。得られた結果は次のとおりである。1. 無給餌飼育(水温19.4~22.0°C)をした場合の仔魚の生存日数は8日間で,体長の伸長は卵黄,油球が残存する孵化後4日目まで認められたが,以後日数が経過するに伴ない縮少した。2. 初期の無給餌(開口後2日間)は短時間の飼育では仔魚の成長,歩留りおよび発育に遅れをもたらすが,飼育期間が長くなるに伴ない漸次回復する傾向が認められた。3. 異なる給餌開始日で飼育した結果,歩留り,成長などから最大限給餌開始日を遅らせることが可能な時期は,卵黄,油球の残存する孵化後4日目までと考えられた。4. 以上の点から孵化仔魚が質的に異なることが考えられ,飼育に適した仔魚を選択する必要があること,またこのことが種苗生産の省力化,計画性の点から必要であることを指摘した。","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_7_19","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/2010102419","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":"初期の飢餓がマダイ仔魚の生残り，成長および発育に及ぼす影響について","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"初期の飢餓がマダイ仔魚の生残り，成長および発育に及ぼす影響について","subitem_title_language":"ja"},{"subitem_title":"The Influences of Initial Delay of Feeding on Survival, Growth and Development of the Red Sea Bream Larvae, Chrysophrys major TEN MINCK et SHLEGEL","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"10","path":["1716951205920"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-04-25"},"publish_date":"2024-04-25","publish_status":"0","recid":"2003357","relation_version_is_last":true,"title":["初期の飢餓がマダイ仔魚の生残り，成長および発育に及ぼす影響について"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-24T04:31:12.864531+00:00"}
