Sterilization agent for sea crab culture and application method thereof

Abstract

The invention relates to the technical field of disease control of aquaculture, and particularly relates to a sterilization agent for sea crab culture and an application method thereof. The sterilization agent comprises Sanhuangfen, Fangcaoduowei, Sailingsan, natural paclitaxel and natural cellulase. The application method of the sterilization agent comprises the following steps of: selecting the sterilization agent according to the area of a culture water body at the dosage of 70-90 grams per mu; and dissolving the sterilization agent into water, and overall uniformly spraying in the culture water body at intervals of 7-10 hours, wherein the sterilization agent is continuously used for 45-50 hours. The sterilization agent for sea crab culture, which is provided by the invention, is higher in excellent activity, is prepared by compounding a stabilizer and a synergist, has the characteristics of broad spectrum, high efficiency, high effect taking speed and the like, enables the water body to be environmentally-friendly, achieves an excellent control effect by adopting a new high-effect high-permeability nanometer technology, and ensures that sea crabs are difficult to be ill and have delicious meat, large yield and high nutritive value.

Description

technical field [0001] The invention relates to the technical field of aquaculture disease prevention and control, in particular, a fungicide used in sea crab culture and an application method are designed. Background technique [0002] A kind of crab disease is common in some sea crab breeding places in my country. The symptoms of this disease are mainly manifested in the abdominal injury of sea crabs caused by parasitism by pathogenic bacteria. The pathogenic bacteria has not yet been identified, and relevant experts believe that it is caused by Aeromonas hydrophila. The sick crab's anus is red and swollen, and the abdomen, belly button and lower part of the back shell are swollen and transparent. The disease mainly harms juvenile and adult crabs, and the incidence rate is relatively high, and the mortality rate of general infection can reach more than 85%. Summer and autumn are the main popular seasons, and the main popular temperature is 24-28 degrees. [0003] Accordi...

Problems solved by technology

[0003] According to current research, these sick crabs are slow to move, eat less food or refuse to eat, and the wounds do not heal naturally, leading to the spread of tissue ulceration at the wound site, and causing a large number of crabs to die from infection.
