Aquaculture system capable of separating and removing shrimp shells and dead shrimps in shrimp circulating aquaculture pond

Abstract

The invention relates to an aquaculture system capable of separating and removing shrimp shells and dead shrimps in a shrimp circulating aquaculture pond and belongs to the technical field of aquaculture. The system comprises an aquaculture pond, an aquaculture pond bottom blow-off pipe, an aquaculture pond bottom shrimp discharging pipe, an aquaculture pond center 'flower pipe', a dead shrimp collecting tank, a shrimp draining cover, a nano air tube, an air conveying hose and a main air supply tube. Dead shrimps can be timely discharged, and spreading of diseases is avoided.

Description

technical field [0001] The invention relates to the technical field of aquaculture, and specifically relates to a culture system for separating and removing shrimp shells and dead shrimp in a prawn circulating water culture pond. Background technique [0002] Penaeus vannamei, also known as Litopenaeus vannamei, scientific name Penaeus (Litopenaeus) vannamei Boone1931, belongs to the phylum Arthropoda, Crustacea, Soft Armour, Decapod, Cladobranchia, Penaeidae, Penaeidae, Penaeus, The subgenus Penaeus is mainly distributed in the tropical waters of the western Pacific coast of America. Penaeus vannamei has the characteristics of: fast growth, 70-100 days in the growth period to reach commercial specifications; long breeding season, year-round breeding and breeding; high breeding density, the highest yield per mu can reach 8000kg; strong adaptability and disease resistance Strong ability, the breeding survival rate is generally above 70%; low nutritional requirements, the pro...

AI Technical Summary

Problems solved by technology

The intensive molting of shrimp in the circulating water aquaculture pond is likely to cause blockage of the "flower tube" in the center of the aquaculture pond, which will affect the stable operation of the system in severe cases

Dead shrimp in breeding ponds can easily lead to the spread of diseases. Therefore, the rapid separation and removal of shrimp shells and dead shrimp in breeding ponds is the technical bottleneck of Penaeus vannamei in recirculating water culture.
