Embodiment Construction

[0016] The present invention will be described in further detail below through examples, and these examples are only used to illustrate the present invention, and do not limit the scope of the present invention.

[0017] EXAMPLES The method of the present invention was used for cultivation in the Changjiang breeding base of Changjiang Jiangnan Biotechnology Co., Ltd. in Changjiang, Hainan.

[0018] The selected breeding ponds are 5# and 6# respectively, with an area of ​​about 4 mu, a depth of 2.2m, a sandy and muddy bottom, a central drainage system and a connection to the water treatment system. After harvesting the shrimps, drain the pond water, let the sun shine until the bottom of the pond cracks, and thoroughly remove the silt and organic matter at the bottom of the pond, barnacles on the pond wall, etc. One month before stocking, use 70-100 kg of quicklime per mu, evenly distribute it on the bottom of the pond, plow and expose to the sun. Enter the water to 20-30 cm. ...

Abstract

The invention discloses a method for controlling a white spot syndrome through mixed culture of Lates calcarifer and Marsupenaeus japonicas. According to the method, 70,000-80,000 young Marsupenaeus japonicas prawns with the overall length being 0.8-1.0 cm are put in each mu of a pond, 8-10 cm long Lates calcarifer are put when the Marsupenaeus japonicas prawns grow to 4-5 cm through culture, and 5-6 Lates calcarifer are put in each mu of the pond. According to the culture method, Lates calcarifer in an appropriate density and in appropriate specifications are put in a high-density intensive culture pond of Marsupenaeus japonicas according to the living habits of Lates calcarifer and Marsupenaeus japonicas, illness and death of the prawns in the culture process can be reduced, a good ecological breeding environment is provided for growth of the Marsupenaeus japonicas, the survival rate of the prawns is increased, the morbidity is reduced, the white spot syndrome is effectively controlled, the culture success rate is high, and the method is suitable for large scale farming development of Marsupenaeus japonicas in China.

Description

technical field [0001] The invention relates to a method for polyculture of barramundi and Penaeus japonicus, belonging to the technical field of aquaculture. Background technique [0002] Shrimp aquaculture is the pillar industry of marine aquaculture in my country. It has developed rapidly in recent years, and its annual output has remained at about 1.3 million tons. However, the stocking density is constantly increasing, the breeding environment is deteriorating, and the disadvantages such as high incidence of diseases are becoming more and more prominent. The problem of prawn diseases is still the main bottleneck in the development of prawn farming. The main measures to solve the problem of prawn diseases include improving the disease resistance of prawns, improving the breeding environment of prawns and cutting off the transmission route of prawn disease pathogens. However, since the outbreak of White Spot Syndrome (WSD) in prawns in 1992, a practical way to completel...
