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.
