Breeding method capable of improving survival rate of red swamp crayfishes

Abstract

The invention discloses a breeding method capable of improving a survival rate of red swamp crayfishes. The method comprises the following steps: performing desilting on a breeding pond, performing washing, performing exposure under the sun, performing disinfection treatment, and adding a compound fertilizer into a water body for water cultivation; planting algae; throwing young red swamp crayfishes into the water body; and throwing feed specially used for the red swamp crayfishes, and changing water once every 2-4 days until the red swamp crayfishes are caught, wherein the feed specially usedfor the red swamp crayfishes comprises the following raw materials in parts by weight: 32-38 parts of fly maggot protein powder, 40-56 parts of rice bran meal, 3-12 parts of fermented biological protein, 6-10 parts of peanut meal, 2-9 parts of soybean meal, 1-5 parts of shell powder, 2-7 parts of radish leaves, 3-11 parts of broussonetia papyrifera leaf powder, 0.1-0.2 part of calcium hydrogen phosphate, 0.01-0.02 part of an enzyme preparation, 0.1-0.3 part of choline chloride, 0.1-0.18 part of allicin, 1-2 parts of a feed attractant, 1-2 parts of montmorillonite, and 2-4 parts of tackifyingcyclodextrin.

Description

technical field [0001] The invention relates to the technical field of crayfish cultivation, in particular to a cultivation method for improving the survival rate of freshwater crayfish. Background technique [0002] Freshwater crayfish is delicious and nutritious. It is a high-protein, low-fat and high-energy, nutritious health food. It is a worldwide edible shrimp and has become an important food source for European people in the 18th century. The nutrition of crayfish is well known. At present, crayfish aquaculture is developing rapidly in my country. During the growth process of crayfish, the feed that is not eaten in time pollutes the water environment, resulting in a high mortality rate of crayfish, resulting in the ineffectiveness of crayfish production. increase while reducing economic efficiency. SUMMARY OF THE INVENTION [0003] Based on the technical problems existing in the background technology, the present invention proposes a culture method for improving the...
