Problems solved by technology

[0002] Sturgeon is a high-quality cold-water fish, and wild sturgeon resources are close to depletion. It is a very urgent task to carry out the multiplication of sturgeon resources and artificial breeding. At present, the artificial breeding of sturgeon with high-density feed has low immunity. Difficult to treat with common medicines and sturgeons are extremely sensitive to commonly used medicines

Abstract

The invention relates to a sturgeon healthy high-density culture method. The method comprises the steps of (a) pond conditions; (b) preparation before stocking; (c) fish frying feeding; (f) daily management, and the sturgeon bait fed in the step (c) is prepared from the following components, by weight, of 10-20 parts of maltodextrin, 20-30 parts of fish meal, 30-50 parts of earthworm powder, 8-12 parts of baker's yeast autolysis powder, 5-10 parts of rice bran polypeptide, 0.5-1 part of decavitamin and 10-25 parts of immunopotentiator; the immunopotentiator is prepared from the traditional Chinese medicine raw materials, by weight, of 6-10 parts of andrographis paniculata, 6-10 parts of Forsythia suspensa, 6-10 parts of root of Chinese thorowax, 6-10 parts of folium artemisiae argyi, 6-10 parts of Codonopsis pilosula, 6-10 parts of Astragalus mongholicus, 6-10 parts of Lonicera japonica, 6-10 parts of Lycium barbarum, 6-10 parts of indigowoad root and 6-10 parts of Houttuynia cordata. According to the method, the sturgeon survival rate is high, the weight gain rate is high, the selected bait quality is high, and the bait coefficient is low.

Description

technical field [0001] The invention relates to a method for healthy and high-density breeding of sturgeon. Background technique [0002] Sturgeon is a high-quality cold-water fish, and wild sturgeon resources are close to depletion. It is a very urgent task to carry out the multiplication and artificial breeding of sturgeon resources. At present, the artificial breeding of sturgeon with high-density feed has low immunity. It is difficult to cure with common medicines and sturgeons are extremely sensitive to common medicines. For example, the common sturgeon septicemia in high-density culture is mainly caused by Aeromonas hydrophila, which belongs to the genus Aeromonas of Vibriaceae, and is a Gram-negative short bacillus with extremely single flagella, no spores and Capsules can produce highly toxic exotoxins. Sturgeons infected with sepsis eat less food, are weak, and have high mortality. This is an urgent problem to be solved in high-density artificial breeding of sturge...
