Description

technical field [0001] The invention relates to the field of compound feed, in particular to an ecological type compound feed for Japanese eel black larvae. Background technique [0002] The Japanese eel belongs to the family Eelidae, also known as the river eel, which belongs to the bony fish class, the order Eelidae, and the family Eelidae. In Japan, South Korea, North Korea and the coast of my country. Because of its tender meat, rich nutrition and delicious taste, it is favored by consumers and has remarkable breeding benefits. In the early days of Japanese eel farming, biological bait was mainly used, but the water quality was easily damaged. The deterioration of water quality and frequent water changes seriously affected the survival rate and the safety of aquatic products. [0003] With the improvement of people's living standards, more and more attention has been paid to food safety issues. In the process of aquaculture, an important link to ensure the safety of aq...
