Further, it is that all after 9~11 days marks in batch production workshop are thick receives that described 29~31 days warm canopy high density, which are temporarily supported,
Shore moves into the little pond of outdoor covering plastic foil to shrimp seedling, and cultivation density is 1,000,000/mu, cultivates 29~31 days.
Outdoor Tu Tang cultivation in described 49~51 days is that the long litopenaeus vannamei to 4~5cm will be temporarily supported through excess temperature canopy high density
Seedling puts in a suitable place to breed to outdoor big Tu Tang according to the density of 10,000/mu and is finally reached listing specification by cultivation in 49~51 days.
Further, warming pipeline is equipped in 9~11 days batch production workshop storage pond, holding ponds；
Further, second batch of 29~31 days warm canopy cultivates little pond, is chosen whether to cover plastic foil according to temperature.
The present invention compared with prior art the utility model has the advantages that
The present invention be limited to cultivate within 1 year one batch by temperature from the traditional prawn culturing method of northern area, and
And in breeding process, the problems such as survival rate of the seed of prawn is low, and disease is difficult to prevention and control, starts with, and has invented a kind of litopenaeus vannamei
" 135 " two batches of classifications connect cultural methods.The present invention comprehensively considers the traditional prawn culturing method in the north, before cultivation
The disadvantages of phase, shrimp seedling individual is small, resistance is weak and the enemy in extraneous pond is more, the shrimp seedling of 0.5cm is temporarily supported in industrial aquaculture
The cultivation in workshop, workshop is equipped with warming pipeline, it is ensured that shrimp seedling grows optimum temperature, marks thick 9~11 days or so；Again by shrimp seedling
Greenhouse little pond is moved into, in greenhouse little pond, shrimp seedling can adapt to extraneous pond environment in advance, and the plastic foil of covering can also mention
It for the appropriate growth temperature of prawn, is temporarily supported 29~31 days by greenhouse little pond, shrimp seedling size is 4~5cm, then by vannamei boone
Shrimp seedling moves into outdoor cultivating pool；Extraneous temperature of cultivation is relatively high at this time, and shrimp seedling reaches certain specification, the enemy in aquaculture pond
Biofacies is to reduction, and the disease high-incidence season that vannamei boone shrimp seedling at this time has been spent, and growth is opposite to tend towards stability, and mentions significantly
The high speed of growth and survival rate in later period.Stringent control temporarily supports the culturing time of " 135 " method, can successfully realize the north
Regional two crops in one year cultivation, the prawn that is staggered list peak period.Entire cultural method is easy to operate, and cultivation achieves noticeable achievement, practicability
