| Outline of Final Research Achievements |
Photoperiod plays a role in the regulation of growth in many fish. We examined the effect of the long-afterglow phosphorescent pigment (LumiNova) on the growth stimulation in a spinefoot and a grouper species. When juveniles of the goldlined spinefoot were exposed to blue-green light from LumiNova at night, high growth was obtained in the experimental group rather than the control group, suggesting that fish are kept under long-day conditions. This result indicates that LumiNova can be used for energy-efficient aquaculture to stimulate the growth of some fish species.
