Mature males from the Lake Kinrin were seen at less than 100mm in body length. On the other hand, mature males from the other rivers were recognized at more than 106mm in body length. Distance between circuli was constant in some cyprinids from the Lake Kinrin. It suggested that individuals growing up at warm water condition in the Lake Kinrin were shown early maturation.","subitem_description_language":"ja"}]},"item_30002_file35":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2009-04-21"}],"filename":"kyo-31-1-5.pdf","format":"application/pdf","mimetype":"application/pdf","url":{"url":"https://our.repo.nii.ac.jp/record/2008759/files/kyo-31-1-5.pdf"},"version_id":"73226840-ed60-4cf1-9299-f912d8a64a63"}]},"item_30002_identifier16":{"attribute_name":"Identifier","attribute_value_mlt":[{"subitem_identifier_type":"HDL","subitem_identifier_uri":"http://hdl.handle.net/10559/13365"},{"subitem_identifier_type":"DOI","subitem_identifier_uri":"https://doi.org/10.51073/13365"}]},"item_30002_identifier_registration17":{"attribute_name":"Identifier Registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.51073/13365","subitem_identifier_reg_type":"JaLC"}]},"item_30002_issue_number25":{"attribute_name":"Issue Number","attribute_value_mlt":[{"subitem_issue":"1"}]},"item_30002_language12":{"attribute_name":"Language","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_30002_page_end28":{"attribute_name":"Page End","attribute_value_mlt":[{"subitem_end_page":"55"}]},"item_30002_page_start27":{"attribute_name":"Page Start","attribute_value_mlt":[{"subitem_start_page":"51"}]},"item_30002_publisher10":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_publisher":"大分大学教育福祉科学部","subitem_publisher_language":"ja"}]},"item_30002_relation18":{"attribute_name":"Relation","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"AA11327096","subitem_relation_type_select":"NCID"}}]},"item_30002_resource_type13":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_30002_source_identifier22":{"attribute_name":"Source Identifier","attribute_value_mlt":[{"subitem_source_identifier":"13450875","subitem_source_identifier_type":"ISSN"}]},"item_30002_source_title23":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_source_title":"大分大学教育福祉科学部研究紀要","subitem_source_title_language":"ja"}]},"item_30002_subject8":{"attribute_name":"Subject","attribute_value_mlt":[{"subitem_subject":"金鱗湖","subitem_subject_language":"ja"},{"subitem_subject":"温泉水","subitem_subject_language":"ja"},{"subitem_subject":"オイカワ","subitem_subject_language":"ja"},{"subitem_subject":"性成熟","subitem_subject_language":"ja"},{"subitem_subject":"鱗隆起線間隔","subitem_subject_language":"ja"},{"subitem_subject":"形態学的特徴","subitem_subject_language":"ja"},{"subitem_subject":"The Lake Kinrin","subitem_subject_language":"en"},{"subitem_subject":"Hot spring water","subitem_subject_language":"en"},{"subitem_subject":"Zacco platypus","subitem_subject_language":"en"},{"subitem_subject":"Maturation","subitem_subject_language":"en"},{"subitem_subject":"Scale circuli","subitem_subject_language":"en"},{"subitem_subject":"Morphological characteristics","subitem_subject_language":"en"}]},"item_30002_title0":{"attribute_name":"Title","attribute_value_mlt":[{"subitem_title":"金鱗湖に生息するオイカワ(Zacco platypus)の形態的特徴I : 性成熟と鱗隆起線について","subitem_title_language":"ja"},{"subitem_title":"Morphological Characteristics of a Cyprinid, Zacco platypus, in the Lake Kinrin I","subitem_title_language":"en"}]},"item_30002_volume_number24":{"attribute_name":"Volume Number","attribute_value_mlt":[{"subitem_volume":"31"}]},"item_title":"金鱗湖に生息するオイカワ(Zacco platypus)の形態的特徴I : 性成熟と鱗隆起線について","item_type_id":"30002","owner":"9","path":["1707983961004","1708494164268"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2009-04-21"},"publish_date":"2009-04-21","publish_status":"0","recid":"2008759","relation_version_is_last":true,"title":["金鱗湖に生息するオイカワ(Zacco platypus)の形態的特徴I : 性成熟と鱗隆起線について"],"weko_creator_id":"9","weko_shared_id":-1},"updated":"2024-03-19T01:06:04.246127+00:00"}
