了解石斑魚的高蛋白需求是否由於部份蛋白用於能量而非成長,藉此確定優質高價魚粉蛋白在石斑魚飼料用量的調降空間.本研究擬以下列方式進行: (一) 以白魚粉或酪蛋白提供完整蛋白源,非必需胺基酸混合物替代完整白源,脂肪含量定為10%,碳水化合物含量為20%. (二) 完整白源提供45%蛋白組為起始組,以5%非必需胺基酸逐步取代,故試驗組完整蛋白含量分別為45%、40%、35%、30%、25%、20%、15%. (三) 以白魚粉提供優質蛋白30%,明膠蛋白、黃豆蛋白、玉米蛋白、小麥蛋白提供15%的蛋白比較成長結果. (四) 以3-10克石斑放養於循環過濾系統中,每缸養10尾,每處理3重覆. (五) 試驗結果測餵食各種飼料後的排氨量,並分析體成份了解蛋白效率. (六) 以統計分析了解提供成長的優質蛋白最適量.本試驗若能證明石斑魚的高蛋白需求是由於部份蛋白用於能量而非成長,則可根據試驗的結果調降飼料中魚粉的用量,並以廉價的植物性蛋白(不考慮胺基酸組成)取代魚粉以降低飼料成本.預計若能充分利用廉價的植物性蛋白取代魚粉則可節省15-20%之原料成本. Grouper is a popular and high price fish among cultured species in Taiwan, Mainland China, Hongkong and southern Asia. Trash fish and powder feed are fed the fish by farmers, which caused the contamination of water quality and sanitary problem of consumer. Using a complete artificial feed can reduce the sanitary problem, improve environment and decrease the capital of wages and feed. It was reported that protein requirement of grouper is 50%,optimal carbohydrate supplement is 20% and lipid supplement is low among cultured carnivores fish. The study is designed to understand wither the high protein requirement is contributed to energy source instead of growth, which will help us to decrease the level of high quality fish protein in grouper feed.
