Breeding method for preventing fulminant hemorrhagic diseases of siniperca chuatsi

Abstract

The invention mainly relates to the technical field of aquaculture, and discloses a breeding method for preventing fulminant hemorrhagic diseases of siniperca chuatsi. The method comprises the steps of pond cleaning, putting and sterilizing; the method is simple, the occurrence rate of the fulminant hemorrhagic diseases of siniperca chuatsi is reduced to 4%, the use and residues of antibiotics andinsecticides are avoided, the method is safe and environmentally friendly, and the heath of the human body is ensured; siniperca chuatsi is placed into a disinfecting solution for short-time soakingbefore stocking, and pathogenic bacteria remaining in siniperca chuatsi can be killed; meanwhile, through biotin added into the disinfecting solution, the activity of epidermal cells of siniperca chuatsi can be improved, the cell gaps are narrowed, the resistance of the epidermal cells to the pathogenic bacteria is improved, the occurrence of various diseases of siniperca chuatsi is reduced, and the breeding cost is saved; after siniperca chuatsi slightly grows up, a bactericide is sprayed into a pond at regular time, the proliferation of pathogenic bacteria is avoided, the nutritional value and disease resistance of siniperca chuatsi are enhanced, the incidence of the fulminant hemorrhagic diseases is effectively reduced, the yield of bred siniperca chuatsi is increased, and the quality of bred siniperca chuatsi is improved.

Description

technical field [0001] The invention mainly relates to the technical field of aquaculture, in particular to a culture method for preventing mandarin fish fulminant hemorrhagic disease. Background technique [0002] The mandarin fish meat is tender, plump and delicious, known for its lack of guts and few thorns. Every 100 grams of meat contains 18.5% protein, 3.5% fat, and about 79 mg calcium. In addition, it also contains phosphorus, iron, vitamin B, and niacin. Qi invigorates the spleen and nourishes the blood, so it is the top grade of fish species; fulminant hemorrhagic disease is mainly caused by bacterial infection in unfavorable environmental conditions, or caused by viral infection, followed by the expansion and spread of pathogenic bacteria, diseased fish gill cover and various There are different degrees of bleeding spots on the fin rays and sides of the body, especially reflected in the fact that the gill valves are full of blood clots and blood mucus, the liver an...
