Abstract

The invention discloses a method for preventing the hemorrhagic lernaea disease of crucian, and belongs to the technical field of fishery industry. The method comprises the following steps: (1) improving the water quality of an aquaculture pond, wherein 3-5 kg of an environment improver is spread in each mu (1 mu is 1 / 6 of acre) of the aquaculture pond for 1-2 times per month; (2) daily feeding an antibacterial antiviral feed prepared from the following raw materials in parts by weight: 20-30 parts of imported fish meal, 20-30 parts of bean pulp, 10-20 parts of plant oil, 3-5 parts of bacillus subtilis, 5-8 parts of peanut meal, 1-2 parts of vitamin C, 2-3 parts of squid organ meal, 5-10 parts of rhubarb powder, 1-2 parts of astragalus polysaccharides and 5-10 parts of tobacco leaf powder. According to the method, while all nutritional requirements of crucian aquaculture are met, the hemorrhagic lernaea disease of the crucian can be effectively prevented, the survival rate and weight gain rate of artificially cultured crucian can be remarkably increased, and the economic benefit can be improved.

Description

Technical field [0001] The invention belongs to the technical field of fish medicine, and specifically is a method for preventing crucian carp hemorrhagic anchor head disease. Background technique [0002] Crucian carp is an omnivorous fish that mainly feeds on plants. It likes to live in groups and live on food. The meat is tender and has high nutritional value.
