台灣可應用於養殖漁業的水、土資源有限，發展海面箱網養殖有其必要性。海鱺成長快速、肉質佳，是現今熱門的箱網養殖魚種之一，開發海鱺專用人工飼料，降低成本、改善肉質有其迫切性。有關海鱺的飼料營養需求資料之建立已有初步之結果，海鱺給予適當良好之脂質可促進增重率並可節約蛋白質之需求。飼料中添加核甘酸對脊椎動物脂質代謝利用有促進之效果，因此本計畫擬於海鱺飼料中以不同含量之核甘酸混合物(等量之AMP、GMP、CMP、UMP、IMP)添加於飼料中進行海鱺飼育試驗以，增重率、飼料效率、活存率、肥滿度、評估其對成長之影響，最後分析肌肉、肝臟、血清之脂質含量及脂肪酸組成，評估其對脂質去飽和轉化能力代謝利用之影響。

The cage culture popular species of cobia. Development special artificial diets are veryimportant for decrease cost and improvement the meet quality of cobia. Optimal lipidrequirement and quality increased growth and sparing the protein requirement of cobia.The dietary supplyment nucleotides for vertebrates increased lipids utilization. Thisstudy will conducted to determine the nutrition valuable of nucleotides for cobia. Theexperiment diets will prepared for supplement 0, 0.05, 0.1, 0.2,0.4 and 0.6 %nucleotides mixture with AMP、GMP、CMP、UMP and IMP in equivalent amountto evaluating the percentige weight gain, Food conversion ratio, survival rate andcondition facter for cobia. After feeding test analsing the lipid and fatty acid of muscle,liver and serum to estimate the nucleotides on lipid utilization of cobia.
