Problems solved by technology

The formation of these technologies greatly satisfies the fast-growing crayfish farming industry’s demand for seedlings and promotes the development of breeding and separation models. However, the construction investment cost of related seedling facilities is not low, and the fishing and transportation of seedlings are labor-intensive and labor-intensive. Affect the survival rate of seedlings

Embodiment 1

[0018] Embodiment 1: the application of the technical solution of the present invention in the shrimp and crab polyculture model is as follows:

[0019] 1. Pond conditions: The area of ​​the aquaculture pond is 15 mu, and the aquaculture pond is transformed into a standard pond: the top width of the pond ridge is 1.5m, the slope ratio of the pond ridge is 1:2, and the excavation around the bottom of the pond is 6m wide and deep A 50cm ring ditch increases the area of ​​crayfish burrowing, and anti-escape nets are set around the pond ridge (pool ridge) with a height of 40cm.

[0020] 2. Preparations before breeding: In winter, drain the pond water, clear the pond, disinfect and sun-dry the pond first, set up anti-escape nets around the pond ridge with a height of 40cm, and plant Elodea.

[0021] 3. Stocking of crab seedlings: stocking crab seedlings from January 20 to February 10, the stocking density is 1000~1500 tails / mu. After the shrimp seedlings are stocked, the water dept...

Abstract

The invention discloses a method and a system for producing berried shrimps of procambarus clarkii in in an earth pond. The method comprises the steps of pond preparation, shrimp seed stocking, culture management, adult shrimp catching, crayfish mating, berried shrimp catching and the like. The system for producing the berried shrimps of the procambarus clarkii in the earth pond can be used for collecting the berried shrimps in a centralized manner, pond transformation is not needed, so that the cost is saved, the collection rate of the berried shrimps of the procambarus clarkii is 80%, the effect is remarkable, and the method and the system are very suitable for popularization.

Description

technical field [0001] The invention relates to the breeding of Procambarus clarkii and related breeding facilities, in particular to a method and system for producing Procambarus clarkii spores in earthen ponds. Background technique [0002] Procambarus clarkii (Procambarus clarkii), also known as crayfish, belongs to Crustacea, Decapod order, Crayfish suborder, Crayfish family, and Procambarus genus. With the rapid growth of domestic consumption, crayfish has become the best-selling freshwater aquatic product species in my country. With the rapid increase of the breeding area and the continuous improvement of consumers' quality requirements for crayfish, the crayfish farming industry has changed from the extensive farming of "large shrimp farming" to the refined farming of "raising large (high-quality) shrimp". The separation of breeding and breeding, and the breeding of seedlings have become the model advocated by Procambarus clarkii farming, replacing the traditional in...
