Industrial breeding technique of Penaeus vannamei

Abstract

The invention discloses an industrial breeding technique of Penaeus vannamei, which adopts indoor industrial shrimp larva breeding. The technique adopts a high-density and systemically controlled-breeding condition breeding mode and constant-temperature dynamic water breeding, recycles breeding water, is high in yield and capable of strengthening artificial preventing and controlling effect on breeding diseases, reducing investment risks and improving economic benefits, contributes to the growth and reproduction of parent shrimps and improve the yield and quality of larvae.

Description

technical field [0001] The invention relates to an industrial seedling raising technology of Penaeus vannamei shrimp seedlings, and belongs to the technical field of aquatic seedling raising. Background technique [0002] Vannamei (Litopenaeus Vannamei), also known as Penaeus vannamei, is listed as one of the three excellent shrimp species with the highest aquaculture output in the world at present along with Penaeus monodon and Penaeus sinensis. It has a long breeding season, fast growth, low nutritional requirements, and adapts Strong and other characteristics. my country introduced the shrimp in 1987, and carried out artificial breeding experiments since 1994. In the past 2 years, it has gradually carried out marine culture in the coastal areas of southern my country and achieved success. The shrimp breeding cycle is short, easy to see results, high income, gradually accepted and favored by the majority of farmers. However, the production of prawn breeding and seedlings...

AI Technical Summary

Problems solved by technology

However, the production of prawn breeding and seedlings in my country is still in an abnormal state: (1) the brood shrimp has problems such as weak constitution, malnutrition, and virus; (4) Due to the deterioration of the ecological environment in the sea area, antibiotics are generally abused in the process of raising seedlings. Although the survival rate has been kept, the immune system function of the prawns has been destroyed, causing commercial shrimp drug inspections to exceed the standard, and export sales are hindered; (5) Artificial The controlled seedling ecological conditions are very different from those of the original natural ecosystem. The shrimps bred in this way are often too weak and the immune system is damaged. In the subsequent breeding process, the shrimps are easily attacked by pathogens and develop diseases.

(6) The nutritional needs of larvae and the application of live bait are not paid attention to in the process of raising seedlings. The seedlings are congenitally deficient, weak in physique, and poor in disease resistance; (7) The quality of seedlings is seriously degraded, their growth rate is slow, and their cultivation period is prolonged.
