Problems solved by technology

At present, there have been reported a variety of methods for the prevention and control of hematopoietic organ necrosis in crucian carp, but there are some problems in them, and the purpose of preventing and controlling crucian carp hematopoietic organ necrosis cannot be better achieved.
The main problems include: 1. Insufficient consideration of prevention and control measures, incomplete prevention and control technology, ignoring some factors that may lead to hematopoietic organ necrosis of crucian carp during the breeding process; 2. The content of prevention and control is not specific, lacking quantitative indicators, Prevention and control technology lacks guiding significance for production practice

Abstract

The invention discloses a comprehensive prevention and control method for crucian carp hematopoietic necrosis. The inventor takes the technological means of fingerling quarantine, vaccine immunization, scientific feeding, immunological enhancement, water quality control and the like into full consideration, and works out time nodes, names of specific drugs and strains, using dosage quantification and the like of all steps in the prevention and control process so as to form a complete comprehensive prevention and control technology. By means of the method, the crucian carp hematopoietic necrosis can be practically and effectively prevented, and the economic benefits of farmers are improved.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a method for comprehensive prevention and control of crucian carp hematopoietic organ necrosis. Background technique [0002] Crucian carp is one of the main freshwater cultured fishes in my country. Because of its delicious meat, fast growth and high yield, it has been widely cultured in my country. In 2015, the total national crucian carp production was 2.9123 million tons. Among them, 630,900 tons were produced in Jiangsu Province and 478,700 tons in Hubei Province. The total output of the two provinces was 1.1096 million tons, accounting for about 38% of the national crucian carp production. Crucian carp herpes virus disease is a newly discovered viral disease infecting cultured crucian carp in my country in recent years. It is highly contagious and has a high fatality rate, which has caused huge economic losses to the crucian carp breeding industry. main thre...
