Embodiment 1

[0024] A method for preventing and controlling organic shrimp farming diseases, comprising the steps of:

[0025] (1) Large to small, shallow to deep: transform the original 1000-5000 mu seawater salt field evaporation pond with a water level of 60-70cm into a single aquaculture pond; A ring ditch is set 10-20 meters away from the four slopes, the width of the ring ditch is 20-30 m, and the depth is 40-60 cm. Each breeding 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) Variety selection: select excellent varieties that focus on stress resistance traits, and varieties that focus on growth speed increase the difficulty of disease prevention and control in the saltfield shrimp farming model;

[0028] (4) Coarse salinization of shrimp seedlings: introduce organic shrimp seedlings, and gradually increase ...

Abstract

The invention relates to an organic shrimp culture disease prevention and control method. The method comprises the following steps of pond trimming, stress-resistant variety selection, 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 controland stress prevention. According to the method, disease prevention and control is a combination of biological prevention and control and physical prevention and control, the shrimp survival rate is improved, and therefore, the acre yield and the total yield are greatly improved.

Description

technical field [0001] The invention belongs to the field of marine aquaculture, and in particular relates to a method for preventing and controlling organic shrimp aquaculture diseases. Background technique [0002] my country is a big country in Penaeus vannamei farming. It has become an important species of Penaeus vannamei in 1999. It has developed rapidly in the three southern provinces and has become the most popular shrimp species in the country. Serious problems such as uneven quality of seedlings, carrying viruses, and slow growth directly threaten the sustainable development of my country's vannamei aquaculture industry; However, the farming area, output, success rate, and product quality of the salt field special ecosystem farming in Shandong, Hebei, Tianjin and other provinces and cities in the north are all rising; Shrimp plays an important role in the aquaculture area and production of the special ecosystem of Yantian. Many shrimps in salt field farming are now ...
