Abstract

The invention discloses a breeding method capable of reducing a case fatality rate of red swamp crayfishes. The method comprises the following steps: selecting a pond with a sufficient water source and no sludge, arranging a heat preservation shed above the pond, draining water in the pond, and performing solarization to obtain a vacant pond; pouring water into the vacant pond, performing disinfection, and planting aquatic plants to obtain a cultivation pond; selecting young red swamp crayfishes with 0.5-1.1 cm, and throwing the selected young red swamp crayfishes into the cultivation pond; performing feeding by feed specially used for the red swamp crayfishes; and changing water every 4-6 days during feeding until the red swamp crayfishes are mature, wherein the feed specially used for the red swamp crayfishes comprises the following raw materials in parts by weight: 24-35 parts of daphnia powder, 4-12 parts of locust powder, 10-18 parts of corn meal, 25-45 parts of peanut protein powder, 10-24 parts of sunflower seed meal, 12-20 parts of skim milk powder, 12-22 parts of houttuynia cordata, 1-4 parts of cortex phellodendri, 1-4 parts of broussonetia papyrifera powder, 0.01-0.02 part of selenium-enriched yeast, 0.01-0.02 part of cellulase, and 1-3 parts of a bean flour complex.

Description

technical field [0001] The invention relates to the technical field of freshwater lobster cultivation, in particular to a cultivation method for reducing the mortality rate of freshwater lobster. Background technique [0002] Freshwater lobster, commonly known as freshwater lobster, belongs to the freshwater lobster family Arthropoda Decapodidae. It has a thick head and chest, a hard shell, and delicious meat. It is a nutritional and nourishing food with low fat, low cholesterol and high protein. Freshwater lobster not only has a large body and plump meat, but also has the characteristics of short growth cycle, high yield, and strong adaptability to miscellaneous food, which is especially suitable for artificial commercial farming. There are technical problems such as single nutrition and high mortality rate of freshwater lobster in the cultivation process of freshwater lobster, which need to be solved urgently. Contents of the invention [0003] Based on the technical pr...
