<p>Cryptocaryon irritans has clear daily rhythms in protomont detachment from fish and theront excystment from tomonts. ​While the rhythms seem to be regulated by photoperiods, it has not been confirmed. ​We investigated whether the daily rhythms of the parasite would be controlled by giving different photoperiods of 12 h light and 12 h dark (06:00–18:00 L and 18:00–06:00 D; 15:00–03:00 L and 03:00–15:00 D) to infected fish and tomonts. ​Protomont detachment and theronts excystment mostly occurred in the last 3 h of the dark period and from 6 h to 3 h before the end of dark period, respectively, indicating that the rhythms are controlled by photoperiods.</p>
