Embodiment 1

[0025] (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

[0026] (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;

[0027] (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;

[0028] (4) WSSV detection: select negative germplasm, larvae, and seedlings as seedlings for salt field shrimp farming;

[0029] (5)...

Abstract

The invention relates to a method for effectively preventing and treating white spot syndrome in salinization shrimp culture, which comprises the following steps of pond trimming, stress-resistant variety selection, WSSV (white spot syndrome virus) detection, coarse salinization of shrimp larvae, feeding of fairy shrimps in the whole process, water quality regulation and control, water quality detection, biological prevention and control, physical prevention and control and stress prevention. All links are negative and can be used as young shrimps for culturing the salinized shrimps, the young shrimps are marked, the early-stage standardized young shrimps are raised, and the later-stage salinization and marking are carried out, so that the survival rate of the shrimps can be improved, and the yield per mu and the total yield are greatly improved.

Description

technical field [0001] The invention belongs to the field of prevention of white spot syndrome in aquatic products, and in particular relates to a method for effectively preventing and treating white spot syndrome in salt field shrimp cultivation. Background technique [0002] White spot syndrome virus (WSSV) is the pathogen that causes white spot syndrome (WSS) in shrimp. Once the disease is prevalent, the mortality rate of prawns in 2 to 7 days can reach 100%. Listed as one of the important aquatic animal viral diseases that need to be reported. The high-density shrimp farming model, deteriorating feeding environment and frequent world trade have all exacerbated the occurrence and spread of the disease. Huge economic losses are caused to the shrimp farming industry every year. In terms of preventing shrimp white spot syndrome, the general method is clearing ponds and disinfection. However, the high-salinity salt field shrimp culture mode is open, and the cost and effec...
