Problems solved by technology

They mainly used disinfectants to compare the toxicity of prawn fertilized eggs, nauplii, flea larvae, mysis larvae and larvae, and to study the effects on the hatching rate of fertilized eggs, but only in laboratory studies
In January 2001, we filed a patent application for the "Detoxification Technology of Shrimp Embryo White Spot Syndrome Virus" to the State Intellectual Property Office, but this technology is only a detoxification technology for eggs
At present, in the large-scale production of prawn fry, the entire production process cuts off the horizontal and vertical transmission of white spot syndrome virus, and produces non-toxic prawn fry, but there is no such production

Embodiment Construction

[0015] Describe in detail the present invention's technology of killing or eliminating white spot syndrome virus in large-scale seed production below by example:

[0016] In the large-scale production of prawn seed, the transmission of white spot syndrome virus is mainly through two ways: vertical and horizontal. Vertical transmission refers to broodstock and spawned eggs, and horizontal transmission refers to seedling water and bait. Therefore, in 2000 and 2001, the avirulent production experiment and detection of the virus were carried out in the production of Chinese shrimp and Japanese shrimp seedlings.

[0017] The operating techniques are: broodstock selection and temporary rearing management; seed cultivation pool disinfection; water treatment during seed cultivation; detoxification of the eggs produced by using the "prawn embryo white spot syndrome virus detoxification technology", and the eggs are first collected In a 0.2 cubic meter container with air stone accompan...

Abstract

It relates to a technology of producing prawn seeds without white spotting syndrome virus. It comprises, first Selecting Parent prawn and temporary cultivated, then disinfecting the incubation pool with the bleaching powder, the potassium permanganate or the formaldehyde; treating seawater for cultivating seeds with 5ppm bleaching powder (available chlorine content) and neutralizing; detoxicatingova and incubating; replacing worms with fish meals and steamed egg custard. The technology is nontoxic.

Description

Technical field [0001] The invention belongs to the production technology of white spot syndrome virus-free prawn seedlings, and is a production technology method for killing or eliminating white spot syndrome virus (WSSV) in the large-scale production of prawn seedlings. Background technique [0002] Before the present invention was made, there were reports and researches on similar aspects both at home and abroad, such as "Several Disinfectants のクルマユビのfertilized eggs およびノウブリウスに to する toxicity" by Kazuo Momoyama of Japan and "Several Kinds of Disinfectants" by Li Tianbao of Shandong Mariculture Research Institute Experiment of Iodine Disinfectants to Prevent Shrimp Explosive Epidemics" (1996) and so on. They mainly used disinfectants to study the toxicity of prawn fertilized eggs, nauplii, flea larvae, mysis larvae and larvae and the impact on the hatching rate of fertilized eggs, but they were limited to laboratory research. In January 2001, we had filed a patent applicat...
