Medaka at about 60-day posthatch were cultured at groups with different sex ratios for 28 days, and the days of first spawning, duration of spawning, and fecundity of each group were investigated. It was found that medaka has the ability of reproduction at about 60-day posthatch under optimal environmental conditions, and the number of eggs per female increased with aging and reached its peak at around 160-day posthatch. When a few males lived with females in one  aquarium, they often did not initiate mating behavior. Also, one male tended to mate up to three females at a time. Furthermore, in order to examine the effect of water temperature elevation on breeding in medaka, mating pairs (8 pairs/group) were cultured at 24℃ or 28℃ for 21days, and the spawning activity was obseved. All pairs which were cultured at 28℃ spawned almost every day. On the other hand, one out of 8 pairs at 24℃ did not spawn throughout the observation period, and the day of first spawning in another pair was extremely delayed, resulting in significant variability in the number of total eggs spawned by each pair. These results suggest that the pair-culture at 28℃ is more appropriate for breeding of medaka.","subitem_description_type":"Other"}]},"item_2_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.18878/00001942","subitem_identifier_reg_type":"JaLC"}]},"item_2_source_id_13":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00085725","subitem_source_identifier_type":"NCID"}]},"item_2_text_9":{"attribute_name":"著者所属(日)","attribute_value_mlt":[{"subitem_text_value":"神戸女学院大学人間科学部環境・バイオサイエンス学科"},{"subitem_text_value":"神戸女学院大学人間科学部環境・バイオサイエンス学科"}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2011-06-01"}],"displaytype":"detail","filename":"KJ00007674679.pdf","filesize":[{"value":"693.0 kB"}],"format":"application/pdf","license_note":"神戸女学院大学研究所","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00007674679","url":"https://kobe-c.repo.nii.ac.jp/record/1981/files/KJ00007674679.pdf"},"version_id":"9c8e45bd-e19c-46b0-af42-4079934b1184"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"メダカ","subitem_subject_scheme":"Other"},{"subitem_subject":"繁殖","subitem_subject_scheme":"Other"},{"subitem_subject":"環境条件","subitem_subject_scheme":"Other"},{"subitem_subject":"生態毒性","subitem_subject_scheme":"Other"},{"subitem_subject":"試験法開発","subitem_subject_scheme":"Other"},{"subitem_subject":"Medaka","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reproduction","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"environmental conditions","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"ecotoxicity","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"development of testing methods","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"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_title":"メダカの繁殖条件に関する基礎的検討:産卵行動における性比及び水温の役割","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"メダカの繁殖条件に関する基礎的検討:産卵行動における性比及び水温の役割"},{"subitem_title":"Basic Study about the Breeding Condition in Medaka(Oryzias latipes):Role of Sex Ratio and Water Temperature in the Spawning Behavior","subitem_title_language":"en"}]},"item_type_id":"2","owner":"3","path":["264"],"pubdate":{"attribute_name":"公開日","attribute_value":"2011-06-01"},"publish_date":"2011-06-01","publish_status":"0","recid":"1981","relation_version_is_last":true,"title":["メダカの繁殖条件に関する基礎的検討:産卵行動における性比及び水温の役割"],"weko_creator_id":"3","weko_shared_id":3},"updated":"2023-06-19T11:30:56.404668+00:00"}
