水產加工副產物循環經濟之效益分析-以金目鱸為例

台灣金目鱸水產加工技術分工完整規模龐大，通常以魚片販售家庭食用，但在加工過程會產生大量魚鱗魚骨副產物，大部分以低價做為飼料原料或者廢棄物方式處理之副產物無法提高附加價值，副產物佔原料魚有一定比例，含有鈣、鉀、磷等元素，可當作人體補充營養原料。本研究利用循環經濟概念，針對金目鱸副產物加工設計骨肉分離、粉末化、魚頭肉、魚骨、魚鱗魚皮等系列製程提升附加價值，並進行成本試算，分析經濟效益，達到提升全魚附加價值之目標。

With perfectly completed divisions, the scale of golden perch market is huge and most of them are manufactured in a type of fillet for family use in Taiwan. However, fish by-products from manufacturing process are also huge and those embodied rich nutrition but usually used as miscellaneous materials and feeding food for animals, or sold by lower prices. Fish bones and scales are full of calcium appropriated as nutritional supplements for all age layers. By using the concept of circular economy and aquaculture golden perch as the implementation case, this study experiments the by-products of fish bone/scales with a series of manufacturing processes in which the powder equipment is implemented. In association with value-added effectiveness, the yield ratios are companied with the experimental results in this study to analyze cost-effectiveness.
