碩士 === 國立臺灣大學 === 漁業科學研究所 === 100 === Kikuchii minnow (Aphyocypris kikuchii. Oshima, 1919), is a native fresh water species in Taiwan and mainly distribute in I-Lan, Hua-Lian and Taitung county. Due to they have beautiful shape and both to have ecological and ornamental value, the habitat has been suffering artificial destruction and environmental pollution. By caught since the demanding of food therefore the number of species and distribution area are shrinking gradually and became a problem. Nowadays we need develop an artificial diet and raising process, but the best n6/n3 essential fatty acid (EFA) research in different temperature was not yet discovered. This experiment generally is in five groups of diets containing control group with 30% fish meal and 0% fish meal, and add soybean oil, fish oil, tallow or soybean oil and fish oil ratio 3:2 separately with total 7% experiment groups. The average body weight were 0.32±0.01g and fed for 6 weeks. Results are diets containing 30% fish meal and 0% fish meal with soybean oil/fish oil ratio 3:2 mix has the best growth and feed efficiency. Result also indicated to raising Kikuchi minnow in 20℃ was better than in 25℃. In 0% fish meal diets containing soybean oil and fish oil ratio 3:2 was the best.
