Embodiment Construction

[0031] A method for staged desalination culture of Penaeus vannamei comprising the following steps:

[0032] (1) Selection of Penaeus vannamei larvae: select 0.5-0.6cm larvae with uniform size ratio, strong vitality, no disease, and no disability, and require the nursery to adjust the nursery salinity of 0.5-0.6cm larvae to 11-13 ‰;

[0033] (2) The first stage desalination culture

[0034] 1) First select an area of ​​20m 2 , the cement pool with a pool depth of 1.0m is used as the first-level desalination tank, and the first-level desalination tank is strictly sterilized. Then add disodium ethylenediamine tetraacetate and methazine to the water in turn, and slightly aerate, then adjust the salinity of the pool water to 12‰, the pool water temperature is 28°C-30°C, the light is controlled at 2000-20000 lux, and the pool is added The adding concentration of disodium edetate is 3.2 g / m3, and the adding concentration of methacine is 0.5 g / m3;

[0035] 2) adjust the water tem...

Abstract

The invention discloses a staged desalinization culturing method for penaeus vannamei boone. The method comprises the steps such as selection of penaeus vannamei boone offspring seeds, a staged offspring seed desalting process, treatment on quality of offspring seed desalination water, treatment on quality of water in a culturing process, routine culture and management and the like. By utilizing the staged desalinization culturing method for penaeus vannamei boone provided by the invention, the problem that penaeus vannamei boone dies due to osmotic pressure change caused by salinity change is overcome, and the desalinization culturing of the penaeus vannamei boone is achieved, thus the method provided by the invention has important practical application value.

Description

technical field [0001] The invention relates to the technical field of freshwater culture of aquatic products, in particular to a staged desalination culture method of Penaeus vannamei. Background technique [0002] Penaeus vannamei shrimp seedlings are the most important shrimp species cultured in my country at present, but in the process of freshwater aquaculture, due to unreasonable desalination methods and technical models, their survival rate is relatively low. Cultivation methods for the survival rate of freshwater aquaculture of Penaeus prawns. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the invention provides a staged desalination culture method of Penaeus vannamei. The method improves the survival rate of freshwater culture of Penaeus vannamei. [0004] The technical scheme that the present invention adopts for realizing the above object is as follows: [0005] A method for staged desalination culture of Penaeus van...
