At present, the market space of my country's aquatic feed is more than 10 million tons. While increasing the production of aquatic feed, it is also necessary to consider how to reduce the cost of feed in order to obtain the greatest economic benefits. Protein is the main nutrient in feed and a key factor in determining the cost of feed. Most aquaculture animals require high protein content in the feed, and at the same time rely particularly on the animal protein source - fishmeal, which greatly increases the cost of aquaculture animal feed. In particular, fishmeal will always be a resource that is increasingly in shor...
