example 1

[0014] Selection of breeding pool: Build a breeding pool indoors, with a size of 40 square meters. There are multiple artificial nests to meet the habit of crayfish making holes in the breeding process. It is also equipped with a feeding table, water changing system, oxygenation equipment, temperature A monitoring device, and a layer of stones and tiles are placed on the bottom of the pool to facilitate the crayfish to hide. Algae are planted in the water. The water depth in the pool is about 1 meter. Add lighting, ventilation and temperature control equipment indoors.

[0015] Selection of broodstock: Broodstock can be selected from natural waters fishing or artificially cultured ponds. The broodstock selected for breeding must be over 10 months old, weigh 30 grams, have good body shape, strong physique, pure body color, and well-developed gonads. , the body length of female shrimp is more than 6, the male shrimp is about 8m, and the ratio of male to female reaches 3:1; put 9 ...

Abstract

Disclosed is a cray indoor artificial reproduction method. The method comprises the steps of reproduction pool selection and building, parent cray selection, food putting, and daily management. According to the cray indoor artificial reproduction method, the indoor reproduction technology is adopted, the environment temperature is well controlled to get rid of the limit of natural conditions, it is ensured that the environment temperature which is most suitable for cray reproduction is kept in the cray reproduction process, and the young cray survival rate is greatly improved.

Description

technical field [0001] The invention relates to the field of propagation, in particular to a method for artificial propagation of crayfish indoors. Background technique [0002] The protein content in crayfish is very high, and the meat is soft and easy to digest. It is an excellent food for people who are weak and need to take care of themselves after illness; shrimp meat is also rich in magnesium, zinc, iodine, selenium, etc. Magnesium is good for the heart. Exercise has an important regulatory effect and can protect the cardiovascular system. It can reduce the cholesterol content in the blood, prevent arteriosclerosis, and at the same time expand the coronary arteries, which is beneficial to the prevention of high blood pressure and myocardial infarction. [0003] Due to the high value of crayfish, the existing breeding technology often adopts outdoor free-range breeding, which is difficult to control temperature changes, resulting in a low survival rate of crayfish seedl...
