Fish meal is a high-protein feed material that uses one or more fish as raw materials and is processed by degreasing, dehydration and crushing. The fishmeal producing countries in the world mainly include Peru, Chile, Japan, Denmark, the United States, the former Soviet Union, Norway, etc. The export volume of Peru and Chile accounts for about 70% of the total trade volume. According to the statistics of the World Food and Agriculture Organization (2013), China's annual fishmeal production is about 1.2 million tons, accounting for about half of the total domestic fishmeal consumption. Although fish meal is still an important animal protein additive, feed workers in China have been studying and exploring low fish meal diet and fish-free diet, and fermented soybean meal is the best alternative product.
