本研究利用傳統分析法化驗水產配合飼料中之蛋白質、水分、脂質、灰分、粗纖維含量，再與近紅外線反射光譜儀(NIR)分析結果比較，求取其間之複式直線迴歸方程式。經以NIR分析268種水產飼料，其中包括鰻魚、草蝦、淡水長臂大蝦、斑節蝦、吳郭魚、尼羅魚、鱸魚、虱目魚、鯛魚、烏魚用飼料，得知蛋白質、脂質、水分、灰分、粗纖維各成分檢量線與傳統分析法所測值之r值，分別為0.997、0.984、0.929、0.909、0.932，實驗結果顯示，水產飼料一般成分之粗蛋白質及脂質可以NIR分析法檢測。

Near-infrared reflactance (NIR) spectroscopy was used to analyze the proximate composition of fish feed. The proximate composition of total of 268 various commercial aquatic feeds including for the species of eel, black tiger shrimp, fresh water prawn, kuruma prawn, tilapia, tilapia aurea, pearch, milkfish, bream, mullet, were compared either determined by NIR method or by the official CNS method. A partial least square regression analysis indicate that the correlation (r) values of the two methods were 0.997, 0.984, 0.929, 0.909 and 0.932 for crude protein, lipid, moisture, ash and crude fiber respectively. Those data suggest that the NIR method may be applied in monitoring crude protein and lipid contents of aquatic feeds.
