| Outline of Final Research Achievements |
We established a self-feeding system for goldfish, which enabled it to continuously feed on demand. By using this system, we examined the effects of background color and blue LED light on the feeding and growth characteristics of goldfish. The results suggest that: 1) a black background promotes higher growth than does a white background, 2) blue LED light is more effective than fluorescent light in stimulating appetite, and 3) background colors affect energy metabolism rather than appetite.
