鱸魚、白蝦與石斑魚是臺灣主要的水產養殖生物種類,平均年產量逾2萬公噸,由於 飼料是水產養殖排放溫室氣體的最主要來源,故本計畫擬透過利用海洋資源,如頭 足類內臟廢棄物及海藻,以發酵或水解技術獲得新型態水解蛋白,取代進口高碳排 蛋白飼料原料,降低魚粉使用量及改善飼料效率,以減少養殖鱸魚、白蝦與石斑魚 所排放的溫室氣體當量;國內養殖生產每公噸白蝦約產生9.37噸CO2當量,約有 7.5噸CO2當量來自水產飼料,藉由白蝦設施養殖各成長階段營養需求及投餵方法之 建立,降低飼料浪費以減少水產養殖飼料用量及溫室氣體排放量。本年度預計進行 鱸魚飼料投餵管理之碳排放量基準探討,並以新型態水解蛋白導入鱸魚飼料,開發 提高飼料效率配方1式,以減少飼料用量及二氧化碳排放量。

研究報告摘要(英)


Sea bass, shrimp, and grouper are the main aquaculture species in Taiwan, with an average annual output of more than 20,000 tons. Feed is the main source of greenhouse gas emissions from aquaculture, this plan intends to utilize marine resources, such as cephalopod viscera And seaweed, using fermentation or hydrolysis technology to obtain a new type of hydrolyzed protein to replace imported high-carbon protein feed raw materials, reduce the use of fish meal and improve feed efficiency, thereby reducing the greenhouse gas equivalent emitted by aquaculture. About 9.37 tons of CO2 equivalent are produced per ton of shrimp farming, of which about 7.5 tons of CO2 equivalent comes from aquaculture feed.  Through the establishment of nutritional requirements and feeding methods at each growth period of shrimp, reduce feed waste to control aquaculture feed consumption and greenhouse gas emissions. This year, we expected to discuss the carbon emission benchmark of bass feed management, introduce a new type of hydrolyzed protein into feed, and develop a formula to improve feed efficiency to reduce feed consumption and carbon dioxide emissions.
