Abstract
This study was conducted to investigate the growth and skin color of red- and white-colored fancy carp Cyprinus carpio var. koi juvenile reared at different water temperatures (21, 24, 27, and 30°C ) for eight weeks. Two experimental diets were prepared to contain 10% Arthrospira platensis or 10% Arthrospira pacifica powder. After the feeding trial, survival was 100% in all group. Weight gain of fish reared at 24, 27, and 30°C was higher than 21°C group. Feed efficiency was not affected by water temperature and dietary Arthrospira sp. Daily feed intake tended to increase with water temperature. The a∗ value of skin coloration was affected by Arthrospira sp., but not by water temperature. Fish fed the diet containing A. pacifica powder reared at 27°C had the highest a∗ value among the groups. Total carotenoids were highest in fish fed the diet containing A. pacifica powder reared at 21°C . Based on the results of this study, we conclude that 24- 30°C water temperature was the optimal range for growth, and dietary inclusion of A. pacifica improved the skin redness of red- and white-colored fancy carp reared at 27°C .
