Quality improver for river crab culture as well as preparation method and application of quality improver

Abstract

The invention belongs to the technical field of aquaculture, and particularly relates to a quality improver for river crab culture and a preparation method and application thereof. According to the scheme, on the basis that sclareolide reported in the prior art has the antibacterial property, the characteristic that sclareolide can inhibit and eliminate bacterial biofilms is found, and the removal effect of sclareolide on staphylococcus aureus and escherichia coli biofilms is verified. The sclareolide is used as the quality improver for river crab culture, the antibacterial property and the antiviral property of the sclareolide are utilized to well protect river crab culture, and meanwhile, the characteristic advantage that the sclareolide can eliminate bacterial biofilms is utilized, so that the drug resistance is effectively reduced, and the river crab culture quality is improved. The compound can be used for preventing and treating diseases caused by staphylococcus aureus and Escherichia coli, and accords with the development direction of healthy breeding.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a quality improver for river crab culture and a preparation method and application thereof. Background technique [0002] Eriocheir sinensis (commonly known as river crab and hairy crab) is an important freshwater aquaculture crab, which is favored by people for its delicious meat and can create huge economic value. However, with the rapid development of intensive aquaculture, various diseases caused by pathogens such as bacteria, viruses and parasites are becoming more and more serious, causing significant economic losses to the crab aquaculture industry. At present, in the aquaculture industry, including river crab farming, the treatment of bacteria, viruses and other hazards is mainly the application of antibiotics. The problem of the abuse of antibiotics has generally occurred, which not only increases the cost of breeding, but also seriously affects the qual...
