Embodiment 1

[0032] Penaeus vannamei shrimp seed circulation desalination cultivation method among the present invention comprises the following steps:

[0033] S1. Seedling selection

[0034] Select healthy, non-disabled, vigorous seedlings with a body length of about 0.55 cm, and control the water salinity of the seedlings of about 0.55 cm to 11.5-12.5 ‰ (preferably 12 ‰);

[0035] S2. The first stage of desalination, the specific process is as follows:

[0036] S21. Choose an area of ​​16‐18m 2 (preferably 17m 2 ), a cement pool with a depth of 1.2-1.5m (preferably 1.3m) is used as a primary desalination pond, and 20-30cm of water is injected into the primary desalination pond; the temperature of the water body in the primary desalination pond is controlled to be 28 -30°C (preferably 29°C), salinity of 11.5-12.5‰ (preferably 12‰), illumination of 5000-10000lx (preferably 8000lx), and inflate the water body of the primary desalination tank; About 30 days before seedlings, in the water ...

Abstract

The invention discloses a penaeus vannamei fry circulation desalination cultivation method. The method comprises the steps of S1, fry selection; S2, first-stage desalination; S3, second-stage desalination; S4, third-stage desalination. According to the penaeus vannamei fry circulation desalination cultivation method, the period of penaeus vannamei desalination can be shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating shrimp seedlings of Penaeus vannamei in circulation and desalination. Background technique [0002] Penaeus vannamei is one of the three most productive shrimps in the world today. The meat is delicious, and the processed meat rate can be as high as 67%. It has a wide temperature range and can grow at 18‐32 °C. It grows under the condition of salinity 1-40‰, and is an excellent desalination cultured species. [0003] The salinity (27‰~32‰) of the shrimp juvenile breeding pond of Penaeus vannamei is very different from that of the breeding pond. Therefore, the shrimp seedlings purchased from the southern nursery must be desalinated and standardized. [0004] The general process of the desalination of shrimp seedlings in the prior art begins to desalinate after a few days of throwing seedlings, discharges a certain amount of salt water into the cultivation pond...
