The photo-period in each tank was regulated by a timer and water temperature was maintained at 22-24°C during the experiment and the spawning time was determined by checking the existence of spawned eggs on the net placed at the overflow outlet of each tank every 15 minutes.<br> In experiment 1, two females continued daily spawning. Spawning occurred during 1700-1900 hr when the fish were kept under a photophase of 0500-1900h (14L10D). When the photo-phase was shifted from 0500-1900h to 0100-1500h (14L10D), the spawning time was advanced by an average of 3.2 hours. Thereafter, we delayed the time of lights-on by 4 hours (10L14D); how-ever, spawning time was delayed only 0.7 hours. By delaying the time of lights-off by 4 hours (14L10D), spawning time was delayed 2.6 hours. In experiment 2, four females continued daily spawning. When the time of lights-off was advanced 4 hours (10L14D), spawning time advanced 3.1 hours. These results indicate that the spawning time is determined photoperiodically. The time of lights-off seems more significant than that of lights-on in the regulation of spawning time, indicating that “lights-off” is working as a synchronizer."}],"abstractLicenseFlag":"disallow"}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1410001206412319361","@type":"Researcher","personIdentifier":[{"@type":"NRID","@value":"9000020032541"}],"foaf:name":[{"@language":"en","@value":"Zhu
