Description

The intensive high density circulating water culture system of Penaeus Vannmei

Technical field

The utility model belongs to aquaculture technical field, and in particular to a kind of intensive high density of Penaeus Vannmei is followed Ring water cultivating system.

Background technology

Penaeus Vannmei is called white limb shrimp, white shrimp, is one of highest three big shrimps of cultured output in the world.Adult is most Long reachable 24cm, crust is relatively thin, and normal body colour is shallow cinerous, and whole body does not have speckle.The thin body fertilizer of Penaeus Vannmei shell, meat are fresh U.S., it is full of nutrition, it is marine product extremely welcome in the market, in the world, it is excellent that Chinese prawn export has also formed scale Gesture.With the improvement of people's living standards, and logistics further development, the market area of Penaeus Vannmei will constantly expand Greatly, potentiality will further be excited.

Traditional culture of Penaeus vannamei pattern is mainly the extensive style cultivation of the native pool, southern feed coefficient intensive culture pattern, northern room Interior cement pit changes ability of swimming and cultivates three kinds of aquaculture models.

1st, native pool extensive style cultivation

Penaeus Vannmei soil pool extensive style aquaculture model bottom of pond is mostly mud or argillo arenaceous；Water source have it is salty have it is light；The depth of water can be shallow It (such as 1.3 meters), can deeply (such as 3 meters)；Oxygenation measure can have, can nothing；Blowdown can have, can nothing；Cistern can have, can nothing.Therefore soil Pool extensive style cultivation cost of investment is more cheap, mainly the input of initial stage Water-quality control, shrimp seedling and later stage feed.However Tu Tang Extensive style cultivation disadvantage is exactly that bottom of pond easily gathers breeding waste, becomes the nutrient of pathogen multiplication, Penaeus Vannmei disease Disease is more difficult to control, and cultivation risk is big, is generally not suitable for high-density breeding.If there is freshwater resources, oxygen increasing equipment, condition of removing contamination It (removes contamination including biology：Beneficial bacterium, mixed breeding fish, algae), it can be achieved that higher density cultivates, if management is proper, yield is reachable 200-500 pounds/acre.

2nd, southern feed coefficient intensive culture pattern

Penaeus Vannmei high-elevation breeding pond pattern is also known as water-lift type intensive culture pattern, appears in Taiwan Province earliest, exists in recent years The ground such as China Guangdong, Hainan, Guangxi, Fujian and Along Zhejiang Coast are rapidly developed.The pattern refers to more than seawater high-water mark Sandy beach build aquaculture pond and carry out white shrimp cultivation, the difference that more traditional Tidal Flat Reclamation digs pool cultivated pattern maximum is exactly to rest It grows pond to build on sandy beach more than coastline, no matter climax, low tide can drain pool inner water body.Pool wall, bottom use black plastics Film or armored concrete plastering, pond good airproof performance, in addition breeding water can effectively avoid the external world all by disinfecting Water pollution；Bottom blow-down system can play the role of good dirt collection, blowdown under aerator rotation simultaneously, can and into discharging pond Bottom dirt, effectively prevents prawn disease.Using three-level cultivation method, can avoid in single pond culture overlong time, bottom of pond pollution The problems such as serious；It can also carry out stubble cultivation more than a year.Penaeus Vannmei high-elevation breeding pond is a kind of intensive formula cultivation of high density Pattern.

3rd, the indoor cement pit in the north changes ability of swimming cultivation

Cement pit industrial aquaculture pattern is in recent years on China Shandong, Hebei, Tianjin and Liaoning and other places in Penaeus Vannmei room Area's development is very fast, and since northern Isolated from Diseased Scophthalmus maximus is subject to medicament residue and price, many raisers are by transforming turbot The methods of fishpond is increased by fishpond, and ceiling uses light-transmissive film, greenhouse cement pit intensive culture pattern is fast in northern Penaeus Vannmei room Speed is in Northern Coastal Region regional development.However the cultivation later stage, with the rising of cultivation density, the increase of daily ration, feeding quantity, raiser must not Water quality is not controlled by increasing quantity of exchanged water, in addition underground well water source quality is also contaminated and the influences such as vibrios in recent years, Population mean cultivates success rate 30% or so.
