Problems solved by technology

Povidone-iodine solution is used in crab ponds, which can improve water quality, kill harmful bacteria, molds and spores thereof in the water body, and have a strong inhibitory effect on Vibrio, Aeromonas hydrophila, and Edwardsiella; but The water body of the pond is complicated, and the existing povidone-iodine solution has disadvantages such as instability, short action time, and large dosage
At the same time, crabs belong to crustaceans, and they shed their shells several times during the growth process. During the shelling period, they are weak in constitution and low in immunity, and are prone to infection of bacteria and other diseases. The drugs of topical disinfectants will increase the stimulation and cause the shelling period to be prolonged. Affect normal breeding management

Abstract

The invention discloses a compound povidone-iodine solution used in the shelling stage of crabs and a preparation method thereof, belonging to the technical field of aquatic product disinfection. The compound povidone-iodine solution provided by the invention consists of 10-50% povidone-iodine solution, 1-20% 20-hydroxyecdysterone, 30-45% solution A, 10-35% surface active The solution A is composed of 20-50% rhubarb, 10-35% Cortex Phellodendri, 10-35% Scutellaria baicalensis, and 20-50% purified water in terms of mass percentage. The compound povidone-iodine solution provided by the invention can improve the synchronous moulting rate of crabs, improve the immunity of soft-shell crabs during the moulting period of crabs, and avoid cannibalism without affecting the disinfection effect of the povidone-iodine solution itself. ; High content of available iodine and better stability.

Description

technical field [0001] The invention belongs to the technical field of aquatic product disinfection, and relates to a compound povidone-iodine solution for crab shelling stage and a preparation method thereof. Background technique [0002] With the accelerated development of crab farming, people have higher and higher requirements for the quality of crabs that go out of the pond and enter the dining table, and pursue pollution-free green food. In the field of aquaculture, disinfectants are an important factor that directly affects the quality of aquatic products. In the process of crab farming, there is still a long way to go to research on efficient, low-toxic, environmentally friendly and healthy disinfectants. [0003] In the existing crab breeding process, the commonly used, environmentally friendly and safe disinfectant is povidone-iodine solution. Povidone-iodine solution is used in crab ponds to improve water quality, kill harmful bacteria, molds and their spores in ...
