Penaeus vannemei high-yield culturing method

Abstract

The invention discloses a penaeus vannemei high-yield culturing method. The penaeus vannemei high-yield culturing method comprises the steps of establishing a penaeus vannemei pool, preparing the penaeus vannemei pool, selecting penaeus vannemei fry, desalting the penaeus vannemei fry, culturing penaeus vannemei with clean water, controlling water quality, catching the penaeus vannemei and the like. By culturing the penaeus vannemei with clean water in the method, the problems that in existing clean water penaeus vannemei culturing, a water body is muddy, and the water quality is difficult to control when water culture is carried out in advance are solved, the owned culturing water body environment can last for 3-4 years before large-range improvement is needed, the degrading speed is reduced, and water quality is easy to control; furthermore, a hepatic protector and garlic serous fluid are applied in the feeding period, the disease resisting capability of the penaeus vannemei can be effectively enhanced, the effects of liver protection, sterilization and inflammation diminishing are achieved, the yield of the penaeus vannemei is comprehensively increased, and the quality of the penaeus vannemei is optimized; soft shell penaeus vannemei is reduced.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a method for high-yield culture of Penaeus vannamei. Background technique [0002] Penaeus vannamei is one of the three high-quality shrimp species with the highest farming output in the world so far. It has the advantages of strong vitality, wide adaptability to salinity and temperature, strong disease resistance, high survival rate, and suitable for high-density farming. . In freshwater aquaculture, Penaeus vannamei has high requirements on water quality. The water temperature suitable for growth is 23°C-32°C, and the adaptable range of pH value of water is 7.3-8.6. When the pH value is lower than 7 or higher than 9.2, The vitality of Penaeus vannamei has decreased; the lowest tolerable dissolved oxygen value is 1.2mg / L, ammonia nitrogen is required to be below 0.2mg / L, nitrite below 0.1mg / L, hydrogen sulfide below 0.05mg / L, and transparency About 30cm, about 40cm in the ...

In the prior art, the farmers mainly realize the supply of trace elements by feeding compound feeds, but the soft shell phenomenon of prawns still exists. The surface absorbs calcium, magnesium, zinc and other trace elements, not the esophagus, so it is obviously not enough to rely on the feed to supplement
