Embodiment 1

[0028] In 2011, the population of Taihu Lake was used as the basic population of Procambarus clarkii (purchased from farmers in Xiaofeng, Anji), and the family construction of Procambarus clarkii was carried out in the greenhouse of Jiashanyang Base of Zhejiang Freshwater Fisheries Research Institute , the details are as follows:

[0029] (1) Selection and cultivation of parents

[0030] The basic population of Procambarus clarkii was purchased from Taihu Lake population from farmers in Anji, and shrimps with larger individuality, complete appendages and stronger vitality were selected as parents. The procured parents are cultivated in the cement pool of the greenhouse in the way of separate breeding of male and female. The size of the cement pool is 2m*6m*1m, the water depth is 30cm, and the stocking density is about 40 fish / m 2 , water temperature 20-25 ℃, uninterrupted aeration, feeding Macrobrachium rosenbergii shrimp feed and hairtail pieces for parental cultivation, fee...

Embodiment 2

[0040] (1) Parental recapture and intensive cultivation

[0041] The family construction of Procambarus clarkii started on August 2, 2012, and the shrimp bred in the same pond in Anji was recaptured in 2011. A total of 453 male shrimp and 416 female shrimp were caught. The recaptured adult shrimp are soaked and disinfected with 10ppm potassium permanganate, and then placed in cement ponds for breeding. The male and female are separated, and the stocking density is about 40 fish / m 2 , using Macrobrachium rosenbergii shrimp feed and hairtail pieces as bait for prenatal intensive cultivation.

[0042] (2) Parental matching

[0043] On September 11, 2012, the adult shrimp with large individual, complete limbs and no damage was selected as the parent of the family, and the selection rate was 17.26%. According to the method of nest design, the ratio of male and female is 5:1 for mating and directional mating, a total of 30 mating groups.

[0044] (3) Inspection and hatching of br...

Abstract

The invention discloses a method for establishing a family of Procambarus clarkii, comprising the following steps: 1) selection and cultivation of parents, 2) mating and cultivation of parents, 3) selection and hatching of egg-bearing shrimps, 4) cultivation of juvenile shrimps, 5) For marking shrimp cultivation and breeding in the same pond. The method of the invention is reasonable in design and strong in operability. Through the research on the family establishment and early growth comparison of Procambarus clarkii, the foundation is laid for large-scale family construction and breeding, and it is helpful for the breeding of excellent growth such as rapid growth. The new strain of traits can change the current situation that seedlings can only rely on fishing from natural waters or relying on the pond shrimp cultured in the previous year for self-propagation and self-breeding and multi-generation breeding, forming a systematic maintenance of excellent Procambarus clarkii species and breeding technology system.

Description

technical field [0001] The invention belongs to the technical field of freshwater shrimp breeding, and in particular relates to a method for establishing a family of Procambarus clarkii. Background technique [0002] Procambarus clarkii ( Procambarus clarkii ), commonly known as freshwater crayfish, belongs to the phylum Arthropoda, Crustacea, Decapod, Cryridae, and the genus Procambarus. Originally produced in North America, since it was introduced into my country in the 1930s, it has been widely distributed in my country and has formed a natural population available for use, especially in the middle and lower reaches of the Yangtze River. An important freshwater shrimp resource, it is also a leading product for the provinces in the middle and lower reaches of the Yangtze River to earn foreign exchange through export, and is very popular in domestic and foreign markets. According to the 2011 Fishery Statistical Yearbook, in 2010, the total aquaculture area of ​​Procambar...
