Example Embodiment

[0016] The present invention is further illustrated by a breeding example in a rectangular breeding pond with an area of ​​about 300 acres and a north-south direction in a farming demonstration base of Penaeus vannamei in Guanyi Xiantao Village, Guanyi Xiantao Village, Changde City, Hunan Province from 2014 to 2015.

[0017] (1) The establishment of the shrimp pond: the depth of the shrimp pond is 1.8-2m, the bottom of the pond is flat and does not leak water and is slightly cleaned toward the drain;

[0018] (2) Preparation of shrimp ponds: carry out drying ponds, dredging ponds, clearing ponds, disinfection, and water intake according to conventional methods, and the water depth shall be kept at 1m-2m;

[0019] (3) Selection of shrimp seedlings: select F1 seedlings that are free of specific diseases and have full gastrointestinal, transparent body color, plump body, regular size, no deformities, and high jumping ability;

[0020] (4) Shrimp larvae desalination: According to the conve...

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 ...
