Embodiment Construction

[0015] 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.

[0016] EXAMPLE The method of the present invention was used to cultivate Penaeus japonicus in Zhanjiang Donghai Island Experimental Base.

[0017] The selected experimental ponds are 1# and 2# respectively, with an area of ​​1333m 2 , 1.5m deep pool, sandy mud bottom, with a central drainage system and connected 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. Chlorine preparations are used to disinfect t...

Abstract

The present invention discloses a method for controlling bacterial diseases by co-culturing Siganus ConcatenaluJ and Penaeus japonicus. The method comprises the following steps: putting young shrimps of Penaeus japonicus with a full length of 0.8-1.0 cm, wherein the putting density is 70,000-80,000 shrimps / mu; and when the lengths of the Penaeus japonicus are 2-3 cm, putting Siganus ConcatenaluJ with the length of 2-3 cm, wherein the putting amount is 500-600 fish / mu. According to the method for controlling bacterial diseases by co-culturing Siganus ConcatenaluJ and Penaeus japonicus, the Penaeus japonicus with herbivorous property can eat baits, faeces, plankton and Enteromorpha, so that the contamination of the water of a pond and the bottom of the pond is reduced, the environment of the aquaculture pond is improved, the content of harmful bacteria in the pool water and sludge is lowered, and the occurrence and spread of bacterial diseases in culturing of the Penaeus japonicus are controlled. By co-culturing the Siganus ConcatenaluJ and the Penaeus japonicus, the excessive nutrition on the bottom of the pond and in the water of the pond can be eliminated timely, the bacteria number is reduced, the breakout of the bacterial diseases is prevented and the culturing success rate is improved.

Description

technical field [0001] The invention relates to a method for controlling bacterial diseases by polyculture of bluefish 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. In addition to the hazards of viral diseases such as Vitiligo Syndrome, Taura Syndrome, and Yellow Head Disease, comprehensive diseases such as Stealing Death Disease and Hepatopancreatic Necrosis are becoming more and more serious. Especially the occurrence of prawn early mortality syndrome (Early Mortality Syndrome, referred to as EMS) disease has caused a catastrophic blow to the enti...
