Abstract

The adult river crab feed consists of fish meal, bean residue, corn powder, mineral salts, ink fish powder, betaine, fish oil, vitamines, 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 invention relates to a feed for crabs, more specifically to the formulation of feed for adult crabs, that is, Chinese mitten crab (Eriocheir sinensis), and also relates to a method for making compound feed for adult crabs from the feed formula. Background technique: [0002] The quality of river crab feed is one of the key technologies for the success or failure of river crab farming. River crabs are active at night, timid, and eat slowly. When they eat, they use their claws to grab feed, requiring the feed to have a certain hardness. Because the mouth of river crabs is surrounded by jaws, feed is missed while eating. Therefore, a good crab feed should meet the following conditions: good palatability, crabs love to eat; low feed coefficient, crabs eat less and grow fast; water-resistant, so that feed will not be missed when crabs feed, reducing feed waste. [0003] The literature on river crab bait includes: "Research on artificial compound bait ...
