Icy fish preservative used for river crabs

Abstract

The invention discloses an icy fish preservative used for river crabs, and belongs to the technical field of aquaculture. The icy fish preservative is prepared from yeast powder, sodium benzoate, calcium chloride, magnesium sulfate, betaine and corn starch; the raw materials are mixed according to a proportion, packaging is carried out, and thus the icy fish preservative for river crabs is obtained. According to the invention, a rot phenomenon of icy fish caused by the breeding of bacteria can be effectively avoided during a thawing process, the icy fish preservative is rich in nutrient elements such as calcium and magnesium needed for the hard shell of the crab crabs, and the icy fish preservative can help the hardening of a carapace. Betaine and yeast powder in the icy fish preservative can significantly improve the ingestion of the river crabs, the specifications of the river crabs will be favorably increased in the late stage, the river crabs are fattened, sperm of the river crabs is promoted, and the culture efficiency of farmers is increased.

Description

technical field [0001] The invention relates to a fresh-keeping agent for ice fish used by river crabs, belonging to the technical field of aquaculture. Background technique [0002] Every July and August are the key seasons for river crabs to grow fat and fatten, and it is also the final stage of river crab breeding. In order to improve the quality, output and benefit of river crabs, farmers usually increase the feeding of animal food in the later stage, mainly ice fish Mainly, the feeding amount during the fattening period can account for about 60% of the total feeding amount to promote the growth of river crabs, gonad development and the accumulation of various nutrients. However, due to the high temperature at this time, the ice fish is prone to corruption and odor during the process of thawing on the same day, and various bacteria breed, and it is easy to deteriorate the water quality after being used in the pond. On the one hand, farmers have to operate under high tem...

Problems solved by technology

However, due to the high temperature at this time, the ice fish is prone to corruption and odor during the process of thawing on the same day, and various bacteria breed, and it is easy to deteriorate the water quality after being used in the pond.

On the one hand, farmers have to operate under high temperature, and on the other hand, they also have to endure the odor caused by the deterioration of ice fish, but there is no targeted product on the market to solve this problem
