Problems solved by technology

[0005] At present, there is no artificial breeding of freshwater lobsters in China. The source of freshwater lobsters is only wild, and the wild population is seriously degraded. There are also shrimp species with unstable performance, sexual violence and mutual killing, and do not like to live in groups for food. The number of eggs laid is small and the individuals are small. Slow growth and reproduction, small feeding area, poor adaptability, no cold and heat resistance, less meat and poor quality, poor adaptability to the environment

Embodiment Construction

[0024] (1) Selection of hybrid parents. Parents use gram crayfish with a body weight of 93 grams to 150 grams and a strong physique as the female parent, and Australian freshwater lobsters with a body weight of 180 grams to 250 grams and a strong physique as the male parent for multi-generation selection. Breeding repeated hybridization.

[0025] The crayfish belongs to the class Crustacea, the subclass Molecula, the order Decapod, the family Cuckoldae, and the genus Crayfish. The whole body of Crayfish clarkii consists of two parts, the cephalothorax and the abdomen covered with chitin carapace. The carapace is dark red, and the whole body has 20 segments. The eyes are stalked and protruding. There are 5 pairs of appendages on the head, 2 pairs of antennae are more developed, 8 pairs of appendages on the chest, the last 5 pairs are walking legs, and the first 3 pairs of walking legs have crabs. The abdomen is short, with 6 pairs of appendages, the first 5 pairs are swimming...

Abstract

A method for selectively culturing the fresh-water lobster includes such steps as choosing strong Keao shrimp as female parent, and strong Australia fresh-water lobster as male parent, hybridizing to obtain the first generation lobster, choosing its female lobster as female parent, hybridizing with the male Australia fresh-water lobster to obtain the second generation lobster, and selective culture to obtain high-quality target lobster.

Description

technical field [0001] The invention belongs to a method for selecting and breeding freshwater lobsters. Background technique [0002] Freshwater lobster (also known as freshwater crayfish or crayfish) is a precious aquatic economic animal. Unique meat flavor, high protein content, low fat content, shrimp roe has the taste of crab roe, especially rich in calcium, phosphorus, iron, zinc, iodine, and rich in selenium, vitamin A, vitamin C, low sugar, low fat, Low cholesterol, high protein content in the body, accounting for 16%-20% of the total. Moreover, the fat contained in freshwater lobster is mainly composed of unsaturated fat and fatty acid, which is easy to be absorbed by the human body, especially rich in tropomyosin and paramyosin, which has the functions of nourishing the kidney, strengthening yang, nourishing yin, and strengthening the stomach. Improving exercise endurance plays an important role. The head and shell of freshwater lobster contain 20% chitin, which...
