The density changed during embryonic development. The eggs in the early to middle developmental stages were less dense than the seawater in the tank in which they were spawned, but at a later developmental stage, they began to increase rapidly in density, becoming more dense than the seawater in the tank by the time of hatching. Larvae that did not move in the first 10 min after hatching became less dense than eggs in the early to middle developmental stages. The osmotic regulation of eggs and larvae may change during development. The results suggented that eggs and newly hatched larvae in the sea would not stay at a certain water level during development. Therefore, passive movement of such eggs and larvae may not always be uniform throughout development, because in situ horizontal flow sometimes varies with depth.[著者抄録]魚卵・仔魚の輸送に関する基礎的知見を得るために,飼育イシダイが自然産卵した卵とそれから孵化した仔魚の密度を, Density-Gradient Column法により測定した.卵の密度は,発生初期から中期には,産卵が行われた水槽内の海水密度よりも小さかったが,発生後期に増加を始め,孵化するまで増加し続け孵化時には飼育海水よりも大きくなっていた.仔魚の密度は,孵化後10分以内に,発生初期～中期の卵と比べて小さくなった.このような密度変化は,卵・仔魚の浸透圧調節の機能と能力が発生とともに変わるためであると推論した.これらの結果はまた,イシダイの卵および孵化仔魚が発生にともない分布深度を変えることを示している.海洋においては水平流の向きあるいは速さが深さにより異なる場合があることから,それら卵・仔魚は発生を続ける間,常に一様に輸送されるとは限らないと考えた.","subitem_description_type":"Abstract"}]},"item_2_description_36":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"記事区分：原著","subitem_description_type":"Other"}]},"item_2_description_41":{"attribute_name":"フォーマット","attribute_value_mlt":[{"subitem_description":"application/pdf","subitem_description_type":"Other"}]},"item_2_publisher_14":{"attribute_name":"出版者 名前","attribute_value_mlt":[{"subitem_publisher":"近畿大学農学部"}]},"item_2_source_id_22":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"04538889","subitem_source_identifier_type":"ISSN"}]},"item_2_text_7":{"attribute_name":"著者(英)","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Tanaka, Yuji"}]},"item_2_text_8":{"attribute_name":"著者 所属","attribute_value_mlt":[{"subitem_text_value":"近畿大学農学部水産学科漁場学研究室"}]},"item_2_text_9":{"attribute_name":"著者所属(翻訳)","attribute_value_mlt":[{"subitem_text_value":"Laboratory of Fisheries Hydrography, Department of Fisheries, Faculty of Agriculture, Kinki University"}]},"item_2_version_type_12":{"attribute_name":"版","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_be7fb7dd8ff6fe43","subitem_version_type":"NA"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"田中,  祐志"},{"creatorName":"タナカ, ユウジ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-02-18"}],"displaytype":"detail","filename":"AN00064044-19900320-0019.pdf","filesize":[{"value":"717.9 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN00064044-19900320-0019.pdf","url":"https://kindai.repo.nii.ac.jp/record/4978/files/AN00064044-19900320-0019.pdf"},"version_id":"596a808e-0820-4f98-8111-c59e77cccd47"}]},"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":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_thumbnail":{"attribute_name":"サムネイル","attribute_value_mlt":[{"subitem_thumbnail":[{"thumbnail_label":"AN00064044-19900320-0019.jpeg","thumbnail_url":"/api/files/15ead863-57b9-450b-bc46-65bf3fda2edf/AN00064044-19900320-0019.jpeg?versionId=504f9c29-6235-4de3-a7db-2e6e0d8ce78a"}]}]},"item_title":"イシダイ卵・仔魚の発生にともなう比重変化","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"イシダイ卵・仔魚の発生にともなう比重変化"},{"subitem_title":"Changes in the Egg and Larval Densities of Striped Beakperch (Pisces; Oplegnathidae) during Development","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["1431","3058"],"pubdate":{"attribute_name":"公開日","attribute_value":"2008-01-28"},"publish_date":"2008-01-28","publish_status":"0","recid":"4978","relation_version_is_last":true,"title":["イシダイ卵・仔魚の発生にともなう比重変化"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-20T19:30:54.171344+00:00"}
