Abstract

The breeding river crab feed consists of fish meal, bean residue, corn powder, mineral salts, ink fish powder, betaine, fish oil, vitamins, eclosion hormone, adhesive and other material. Its production process includes weighing material, mixing, introducing steam, pellitizing, dewatering and cooling. It is delicious and water soaking resistant and suitable for feeding large-eye larva of river crab. Making river crab eat the feed can promote its growth and result in low feed coefficient.

Description

Technical field: [0001] The present invention relates to crab feed, and more specifically to the formula of Eriocheir sinensis (Eriocheir sinensis) crab species feed. The present invention also relates to a method for preparing the feed formula into a compound feed for river crabs and crab species. Background technique: [0002] The quality of crab feed is one of the key technologies for the success or failure of crab breeding. River crabs are active at night, are timid, and eat slowly. They use claws to pick up the feed, which requires a certain degree of hardness, and because the mouth of the river crab is surrounded by jaws, the feed is missed while eating. Therefore, a good breed of crab feed should have the following conditions: good palatability, and love to eat; the feed is resistant to blisters, can be caught when the crab eats, and the feed will not be missed, reducing the waste of feed. In addition, crab species cannot be raised too large or too small. If the crab speci...
