Embodiment 2

[0027] Embodiment 2 Using the cultivation system established in Example 1, Zhanjiang Dehai Industrial Co., Ltd. adopted the parent shrimp cultivation method in the technical solution of the present invention to carry out parent shrimp cultivation for 5 months:

[0028] (1) Water intake: After the filtered seawater is sterilized, add it to the circular runway pool at one time, turn on the water treatment device for trial operation, keep the water depth in the runway pool at 1.2~1.3 meters, the seawater temperature 28~30℃, Specific gravity 1.020~1.023, pH value 7.8~8.2;

[0029](2) Release seedlings: choose vigorous, robust and plump shrimp seedlings with transparent body, full stomach and intestines, body length of 0.8~1.0cm, smooth body surface, non-sticky dirt, and high uniformity for stocking at 40 tails / square meter The density is placed in the runway pool; the shrimp seedlings need to undergo virus quarantine before stocking to ensure that the shrimp seedlings do not cont...

Embodiment 3

[0037] Embodiment 3 Using the cultivation system established in Example 1, Zhanjiang Dehai Industrial Co., Ltd. adopted the parent shrimp cultivation method in the technical solution of the present invention to carry out parent shrimp cultivation for 5 months:

[0038] (1) Water intake: After the filtered seawater is disinfected, add it to the circular runway pool at one time, turn on the water treatment device for trial operation, keep the water depth in the runway pool at 1.2~1.3 meters, the seawater temperature is 28~30°C, Specific gravity 1.020~1.023, pH value 7.8~8.2;

[0039] (2) Release seedlings: choose vigorous, robust and plump shrimp seedlings with transparent body, full stomach and intestines, body length of 0.8~1.0cm, smooth body surface, no sticky dirt, and high uniformity for stocking at 50 tails / square meter The density is placed in the runway pool; the shrimp seedlings need to undergo virus quarantine before stocking to ensure that the shrimp seedlings do not ...

Abstract

The invention discloses a parent litopenaeus vannamei breeding system and method. The parent litopenaeus vannamei breeding system and method are designed and obtained by simulating the natural living state of litopenaeus vannamei. By means of the breeding system, the structure is simple, the energy consumption is saved, and management is convenient; as for the litopenaeus vannamei bred through the breeding system and method, bodies are strong, appendages are sound, body colors are transparent, stomachs and intestines are plump, body surfaces are smooth, attachments are avoided, and the three kinds of viruses including the WSSVes, the TSVes and the IHHNVes are avoided; in addition, the parent litopenaeus vannamei is large in egg laying amount, long in continuous egg laying time and high in nauplius hatchability, metamorphosis rate, young litopenaeus vannamei breeding rate and survival rate.

Description

technical field [0001] The invention relates to a prawn broodstock cultivation system and a broodstock cultivation method, in particular to a prawn broodstock cultivation system and a broodstock cultivation method, belonging to the technical field of prawn cultivation. Background technique [0002] Litopenaeus vannamei ( Litopenaeus vannamei ), also known as Penaeus vannamei, belongs to the phylum Arthropoda (Athropoda), crustacean (Crustacean), decapoda (Decapoda), and is naturally distributed along the Pacific coast from Peru to Mexico. Litopenaeus vannamei has the characteristics of delicious meat, strong stress resistance, fast growth, long breeding period, high density and low salinity resistance, and is conducive to the transportation of live shrimp. After Litopenaeus vannamei was introduced into my country in the 1990s, it quickly solved the key technology of large-scale seed breeding, formed aquaculture models and technologies for different regional aquaculture envi...
