Description

Technical field [0001] The invention belongs to the field of aquaculture feed, and specifically relates to a crab feed for preventing diseases and increasing production. Background technique [0002] River crab (scientific name Chinese mitten crab), because of its unique flavor and nutrition, is more and more popular with consumers at home and abroad. As a high-quality aquatic resource, river crab is favored by farmers in the Great Lakes Basin, especially in Jiangsu Province. However, artificial breeding often causes some bacterial diseases of crabs due to high breeding density, leading to death and low survival rate. To this end, the present invention provides a crab feed for preventing diseases and increasing production. Summary of the invention [0003] The invention provides a crab feed for preventing diseases and increasing production, which is characterized in that the formula is as follows: [0004] 30% fish meal, 26% soybean meal, 8% rapeseed meal, 10% flour, 2% soybean o...
