Embodiment Construction

[0033] The present invention adopts following technical scheme:

[0034] 1 Pond Conditions

[0035] The bottom of the pool is flat, less silt, the slope of the pool dike is 1:2, the water depth is 1.5m~2.0m, and it meets the requirements of SC / T1033.4.

[0036] 2 Clean pond disinfection

[0037] For ponds that have been sun-dried in dry ponds, inject 50cm-70cm of new water 10d-15d before stocking shrimp seedlings, and sprinkle 1875kg-2250kg of quicklime and 150kg of bleaching powder per hectare evenly; Mix 750kg-900kg of tea bran with water and sprinkle the whole pool, and then adjust the water quality with 1500kg of quicklime. After 7d to 10d, a small amount of shrimp seedlings tested in the water and confirmed that the virulence has disappeared, the shrimp seedlings can be officially stocked.

[0038] 3 Seed stocking

[0039] 3.1 Shrimp stocking

[0040] The desalinated shrimp fry with a body length of about 0.7cm per hectare 3.0×10 5 Tail ~ 6.0×10 5 Tail, or young sh...

Abstract

The invention discloses a giant freshwater prawn breeding method and belongs to the technical field of breeding of aquatic organisms such as shrimps in agricultural aquaculture. Giant freshwater prawns with a certain density are bred in a pond with certain specifications; fishes are put into the pond at proper time for mixed breeding; feeding and management of water quality and disease control are carried out during breeding and the whole giant freshwater prawn breeding method can be comprehensively and effectively controlled. The method is simple to operate, low in cost and has remarkable effect, obvious economic benefits and social benefits.

Description

technical field [0001] The invention belongs to the technical field of shrimp aquatic organism cultivation in agricultural aquaculture, and in particular relates to a method for cultivating Macrobrachium rosenbergii. Background technique [0002] Macrobrachium rosenbergii, also known as Malaysian prawns, freshwater long-armed prawns, etc., is known as the king of freshwater shrimps. Its shell is thin and fat, the meat is fresh and tender, and it is rich in nutrition. It has the advantages of fast growth, wide appetite, and short breeding cycle. In freshwater aquaculture in my country, Macrobrachium rosenbergii becomes the second most efficient agricultural production species after river crab. Traditional Macrobrachium rosenbergii culture often has problems such as low emergence rate of shrimp seedlings, unstable quality, poor survival rate during growth, and slow growth rate. Therefore, it is necessary to uniformly standardize Macrobrachium rosenbergii ponds, disinfection,...
