Embodiment 1

[0017] Example 1 The cultivation method of the present invention was used for cultivation in the Zhanjiang East Island Experimental Base.

[0018] The experimental ponds were selected as 7# and 8#, with an area of ​​800m 2 , the pool depth is 2.0m, the sand and mud bottom, there is a central drainage system and is connected to the water treatment system. After each shrimp harvest, drain the pond water, let the sun dry until the bottom of the pond cracks, and thoroughly remove the silt and organic matter on 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, and plough and expose to the sun. Into the water to 20 ~ 30 cm. Chlorine preparations are used to disinfect the bottom of the pool, and the effective chlorine concentration is 30 g / m3.

[0019] The water used for aquaculture was filtered seawater from sand filter wells. About 80-100 cm of water was added 15 ...

Abstract

The invention discloses a method for controlling a white spot syndrome by culturing hybrid giant tiger groupers and marsupenaeus japonicas in a mixed mode. The method comprises the steps that marsupenaeus japonicas seeds with the overall length of 0.8-1.0 cm are put into a pond, the putting quantity is 70,000-80,000 per mu, the hybrid giant tiger groupers with the body length of 8-10 cm are put into the pond when the marsupenaeus japonicas seeds are cultured until the body length of each marsupenaeus japonicas seed is 4-5 cm, and the putting quantity is 10-15 per mu. According to the method, according to the life habits of the hybrid giant tiger groupers and the marsupenaeus japonicas, by putting the hybrid giant tiger groupers in the appropriate density and appropriate specification into the high-density intensive culturing pond of the marsupenaeus japonicas, occurrence of the diseased and dead marsupenaeus japonicas can be reduced in the marsupenaeus japonicas culturing process, a good ecological culturing environment is supplied to growth of the marsupenaeus japonicas, the survival rate of the marsupenaeus japonicas is increased, the incidence is decreased, the culturing success rate is high, and the method is suitable for development of scale culturing of the marsupenaeus japonicas in China.

Description

technical field [0001] The invention relates to a method for controlling white spot syndrome by polyculture of pearl dragon grouper and penaeus japonicus, and belongs to the technical field of aquaculture. Background technique [0002] Shrimp aquaculture is a pillar industry of marine aquaculture in my country. It has developed rapidly in recent years, with an annual output of about 1.3 million tons. However, the stocking density is increasing, the aquaculture environment is deteriorating, and the disadvantages of high disease incidence are becoming more and more prominent. The problem of shrimp disease is still the main bottleneck for the development of shrimp aquaculture. At present, the main measures to solve the problem of shrimp diseases include improving the disease resistance of shrimp, improving the environment of shrimp farming, and cutting off the transmission route of shrimp disease pathogens. However, since the outbreak of White Spot Syndrome (WSS) in prawns in...
