Embodiment 1

[0026] A method for effectively preventing and treating Taura Syndrome in salt field shrimp culture, comprising the steps of:

[0027] (1) Change from large to small, from shallow to deep: transform the seawater salt field evaporation ponds with a water level of 60-70cm over a thousand mu to a few thousand mu into a single breeding pond; Set up a ring ditch 10-20 meters away from the four sides of the primary evaporation pool. The width of the ring ditch is 20-30 m and the depth is 40-60 cm. Each aquaculture pond is set with an independent drainage system

[0028] (2) Pond repair: Drain the water in non-production seasons, use 50-200 kg of quicklime per mu, plow 20-30cm with machinery, and dry for more than 30 days;

[0029] (3) Selection of stress-resistant varieties: select excellent varieties that focus on stress-resistant traits, and varieties that focus on growth speed increase the difficulty of disease prevention and control in the saltfield shrimp farming model;

Abstract

The invention relates to a method for effectively preventing and treating the Taura syndrome in salt pan shrimp culture. The method comprises the following steps of pond trimming, stress-resistant variety selection, Taura virus detection, shrimp seed standard coarse salinization, fairy shrimp feeding in the whole process, water quality regulation and control, water quality detection, biological prevention and control, physical prevention and control and stress prevention. Germplasms, larvae and fries are selected in the method, the Taura virus detection report is checked, all links are negative, the germplasms, larvae and fries can serve as fry for salt pan shrimp culture, the survival rate of shrimps is increased, and therefore the acre yield and the total yield are greatly increased.

Description

technical field [0001] The invention belongs to the field of aquatic products, and in particular relates to a method for effectively preventing and treating Taura syndrome by culturing shrimp in salt fields. Background technique [0002] Taura syndrome, commonly known as "red tail disease", is a serious contagious shrimp disease caused by Taura syndrome virus (TSV). During acute infection, the shrimp body turns red and soft shell, and the transition period of infection Irregular blackening of the horny epithelium. On January 1, 2019, the World Organization for Animal Health (OIE) 2019 Animal Disease Notification Registration Form came into effect. Among the 9 crustacean diseases notified by OIE, Taura syndrome is one of them. Taura syndrome mainly occurs during the molting period of prawns. The prawns do not eat and swim slowly on the water surface. The body of the diseased prawns is weak, and there are red pigmentation in the abdomen and feet. Sometimes the whole prawn bo...
