Cultured rotifer, Brachionus plicatilis, and Artemia nauplii were employed as food organisms. Obser- vations on swimming speed were made on 14, 16, 21, 22 and 26 days after hatching. No significant correlation was found between swimming speed and prey density for 14-day-old larvae. But older larvae swam very slowly just after they were fully fed, and the fish became more active together with decreasing prey density. No decrease of swimming speed occurred at a prey density of more than five rotifers/m/ for 14, 16, 21 days old larvae. Consequently, the swimming activity of larval black porgy are related closely with prey conditions in the tank.","subitem_description_language":"en","subitem_description_type":"Abstract"},{"subitem_description":"クロダイ仔魚の飼育条件下における摂餌行動と餌料密度との関係を明らかにするため,ふ化後14,16,21,22および26日の仔魚に生物餌料(シオミズツボワムシ,アルテミア幼生)を与え餌料密度と遊泳速度の変化を観察した。ふ化後14日目の仔魚は,餌料密度と遊泳速度の間に顕著な相関はみられなかった。ふ化後14日目を除く仔魚においては,給餌前の遊泳速度は速く,摂食直後は最も遅くなった。そして仔魚の摂取による餌料の減少に伴って4mm/sec. 前後であった速度は次第に増加し,給餌前の10~12 mm/sec.になった。また,14~21日目の仔魚にシオミズツボワムシを与えた場合,5個体/ml以上の密度では速度の変化はみられなかった。これらのことからクロダイ仔魚の遊泳速度と餌料密度は密接な関係を有し,餌料が不足した場合は遊泳速度の増加で索餌範囲を拡大していること,またある密度までは餌料の増加に伴い速度が遅くなると推察された。","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_15_97","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/2010271220","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":"eng"}]},"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":"クロダイ仔魚の遊泳に及ぼす餌密度の影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"クロダイ仔魚の遊泳に及ぼす餌密度の影響","subitem_title_language":"ja"},{"subitem_title":"Effect of Prey Density on the Swimming Behaviour of Larval Black Porgy, Acanthopagrus schlegeli (BLEEKER)","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":"2003291","relation_version_is_last":true,"title":["クロダイ仔魚の遊泳に及ぼす餌密度の影響"],"weko_creator_id":"10","weko_shared_id":-1},"updated":"2025-04-21T02:24:35.260227+00:00"}
