Problems solved by technology

[0003] The literature on river crab bait includes: "Research on artificial compound bait for river crab intensive cultivation", "China Feed", Zhang Yungui, etc., 1994, June, 18-20; "Experiment of compound feed to improve the growth specification of river crab" "Qilu Fishery", Tian Zhongyun, etc. , 2000, 17(1), 35-36; these two documents announced some formulations of compound feed for adult crabs, but the disadvantages are that the additive formula is not disclosed, the feed coefficient is higher than 2, and the growth specifications of river crabs are mostly lower than 100. grams, the feed is not resistant to blisters, and the blister resistance time is only 3-6 hours
[0004] So far, there is no patent literature on the formula and preparation method of river crab adult crab feed

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 ...
