Embodiment 1

[0026] A method for effectively preventing and treating EMS 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;

[0030] (4) EMS ...

Abstract

A method for effectively preventing and controlling EMS in salt pan shrimp culture comprises the following steps of pond trimming, stress-resistant variety selection, EMS pathogen detection, shrimp seed standard coarse salinization, whole-process feeding of fairy shrimps, 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 fry for culturing the saltpan shrimps, so that the survival rate of the shrimps is improved, and the yield per mu and the total yield are greatly improved.

Description

technical field [0001] The invention belongs to the field of aquatic products, and in particular relates to a method for effectively preventing and controlling EMS in salt field shrimp cultivation. Background technique [0002] Early Shrimp Mortality Syndrome, technically known as Acute Hepatopancreatic Necrosis Syndrome (EMS or AHPNS for short), refers to a phenomenon that occurs in prawn farming: no dead prawns can be observed in the pond at ordinary times, and there is no obvious phenomenon before the death of prawns. It is difficult to observe when it sinks into the bottom of the pond. It can only be found after a large number of dead shrimps float to the surface or rush to the edge of the pond after a few days. Therefore, it has been more harmful in shrimp farming in recent years. Professor Lightner's team determined that Vibrio parahaemolyticus (Fujino et al. 1951) and Sakazaki et al. 1963, a specific variant of the EMS pathogen Vibrio parahaemolyticus, are Gram-negati...
