Embodiment

[0026] l. Comparing with the normal management method of prawn farming, after cultivating the water, put in about 1.0cm shrimp seedlings, 50,000 to 100,000 tails per mu. Since tilapia is not suitable for living in water bodies with a salinity greater than 15, the salinity of the aquaculture water body described in the present invention is within the range of 0-15. If the salinity of the aquaculture water is greater than 15, the salinity can be reduced by adding fresh water to control the salinity within the above range.

[0027] 2. Put tilapia in time. The prawns are cultured until about 20-30 days, and the tilapias are put in before the outbreak of prawn diseases. During the breeding process, often due to the reasons of the shrimp seedlings themselves, large-scale deaths occurred in the early stage of the breeding, and there was no need to stock the tilapia before. Therefore, when the shrimp seedlings are stable for 20-30 days, the tilapia will be put in again; the numb...

Abstract

The invention discloses a biological prevention and control method for controlling prawn diseases with tilapias. According to the method provided by the invention, tilapias are added into a prawn culture zone, such that prawn infectious disease prevention is realized, and prawn survival rate is improved. With the method, prawn diseases can be prevented from spreading in healthy prawn populations; work load of artificially removing diseased and dead prawns is reduced; removing efficiency and culture success rate are improved; and higher economic benefit is brought to farmers.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a biological prevention and control method for controlling prawn diseases through tilapia. Background technique [0002] Shrimp is a pillar species of my country's aquaculture industry. It has developed rapidly in recent years. By 2009, the aquaculture output was 1.303 million tons, and the output value exceeded 30 billion yuan. Shrimp aquaculture has become the target industry of my country's agricultural industrial structure adjustment. [0003] However, the problem of shrimp diseases is still the main bottleneck in the development of shrimp farming industry. The outbreak of infectious diseases of prawns has a certain relationship with the habit of cannibalism of prawns themselves. In the process of shrimp farming, due to the deterioration of environmental conditions, some prawns with weak constitution and poor disease resistance are the first to get sick or even die. Caused outbr...
