Problems solved by technology

[0003] At present, in order to meet the needs of consumers, the method of artificial breeding is generally used to preserve the eggs of the red crayfish. It is well known that the red crayfish is an egg-bearing shrimp in vitro, and the fertilized egg juveniles are attached to the abdomen of the female shrimp and external environmental factors To a certain extent, it has a significant impact on the hatchi

Example Embodiment

[0022] The following is a detailed description of the method for conserving the seeds of red crayfish crawfish in the present invention with reference to specific examples:

[0023] The above-mentioned method for conserving species of red crayfish crawfish, the method includes the following steps:

[0024] Step 1. Select broodstock, select healthy, large individuals and complete appendages in different places, and sexually mature female and male red crayfish as broodstock for breeding, and put the female broodstock and male broodstock into broodstock breeding ponds. The female broodstock to be mated and the male broodstock to be mated are cultivated in the medium.

[0025] Step 2. Broodstock mating, put the female broodstock to be mated and the male broodstock to be mated into the mating tank, where the ratio of female broodstock to male broodstock should be controlled when putting in.

[0026] Step 3. Induce egg holding, intensively cultivate the broodstock of the red crayfish in the...

Abstract

The invention discloses a breed conservation method for ovigerous shrimps of cherax quadricarinatus. The method includes the steps: selecting parent shrimps; mating the parent shrimps; inducing oogenesis; collecting the ovigerous shrimps; treating ovigerous females; performing low-temperature breed conservation for the ovigerous females; performing temperature-raising development for the ovigerous females. By the method, breeding and breed conservation cycle can be shortened, shrimp seed offspring with low survival rate and high quality is increased, and the requirement for breeding in batches is met. Financing cost input is reduced to a certain degree, and the method is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of artificial breeding of shrimps, in particular to a method for preserving species of crayfish with eggs. Background technique [0002] Red claw crayfish (Cherax quadricarinatus), also known as "Australian freshwater lobster", originates in Australia and is also distributed in New Guinea. Guangdong and Hubei Trial breeding in two provinces was successful. Red claw crayfish is generally 50-100 grams in size, and the largest individual is 500-600 grams. It is a kind of freshwater shrimp with strong adaptability. It has a wide appetite, fast growth, tender meat, delicious taste and rich nutrition. , Japan, especially in the Chinese market by the majority of consumers. [0003] At present, in order to meet the needs of consumers, the method of artificial breeding is generally used to preserve the eggs of the red crayfish. It is well known that the red crayfish is an egg-bearing shrimp in vitro, and the fert...
