Embodiment

[0024] 1. 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 carp is not suitable for living in water bodies with a salinity greater than 7.5, the salinity of the aquaculture water body described in the present invention is within the range of 0-7.5. If the salinity of the aquaculture water is greater than 7.5, the salinity can be reduced by adding fresh water to control the salinity within the above range.

[0025] 2. Put carp in time. The prawns are cultured until about 20 to 30 days, and the grass carp is put in before the outbreak of the prawn disease. During the breeding process, shrimp fry often die on a large scale in the early stage of breeding, and there is no need to stock grass carp before. Therefore, after 20 to 30 days of breeding, carp should be put in after the shrimp seedlings are stable; the number of carp put in should not be less than 30 / mu, a...

Abstract

The invention discloses a biological prevention and control method for controlling shrimp diseases through carps. In the method, carps are put into a shrimp culture zone, so that shrimp infectious diseases can be prevented and the survival rate of shrimps is increased. Through the method, shrimp diseases can be prevented from spreading among healthy shrimps, the workload of manual removing of sick and dead shrimps is lowered, removing efficiency is improved, culturing success rate is increased and greater economic benefit is brought for culturists.

Description

technical field [0001] The invention relates to the field of aquaculture, in particular to a method for cultivating prawns for biological control by adding carp. 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 outbreaks of shrimp disea...
