Problems solved by technology

[0003] However, the artificially cultured Procambarus clarkii has suffered serious population degradation due to inbreeding.
Artificially cultured Procambarus clarkii individuals are generally small and sexually mature early, which has brought huge economic losses to the majority of farmers

Embodiment 1

[0018] A breeding method for keeping the excellent characters of Procambarus clarkii is characterized in that it comprises the following breeding steps:

[0019] 1. Selection and cultivation of parents: select 30 Procambarus clarkii families, each family has 1000-3000 individual 2-3 month old Procambarus clarkii juveniles, measure the body length and weight respectively, and select those with obvious For Procambarus clarkii with growth advantage, one female and one male Procambarus clarkii were selected from each family as alternative parents. The male and female shrimps are selected and marked with PIT, and they are cultured in the breeding pond, the water temperature is kept at 20-25 degrees Celsius, and the air is continuously inflated. During the breeding period, feed and fish pieces are fed, three times a day, and the feeding amount is 20 minutes Just eat as much as you can.

[0020] 2. Establishing a family line: After the Procambarus clarkii reaches sexual maturity, us...

Abstract

The invention discloses a breeding method for maintaining the excellent traits of Procambarus clarkii. The method belongs to the field of animal molecular breeding, and specifically relates to a breeding method for maintaining the excellent traits of Procambarus clarkii. Through parental selection and cultivation, establishment of family, hatching and seedling, breeding of a family with excellenttraits, calculating the kinship between different individuals, re-selecting parents to cultivate, the excellent traits of stable Procambarus clarkii can be cultivated after multiple generations of breeding. The method lays a foundation for the construction and breeding of large-scale families, which is helpful for breeding new strains with excellent growth traits.

Description

technical field [0001] The invention relates to a breeding method for maintaining the excellent traits of Procambarus clarkii, belonging to the field of animal molecular breeding. Background technique [0002] Procambarus clarkii is shrimp-like and has a hard shell. The body length is about 5.6-11.9 cm, dark red, and the upper part of the carapace is black. It is a freshwater economical shrimp. It is loved by the people because of its delicious meat taste. Because of its omnivorous nature, rapid growth, and strong adaptability, it has an absolute competitive advantage in the external environment. Its food range includes aquatic plants, algae, aquatic insects, animal carcasses, etc. [0003] However, the artificially raised Procambarus clarkii has suffered serious population degradation due to inbreeding. Artificially cultured Procambarus clarkii individuals are generally small and sexually mature early, which has brought huge economic losses to the majority of farmers. ...
