Embodiment 1

[0020] In fine weather, choose the 10:00 spraying at a slightly lower ambient temperature, use the high-precision German sartorius original imported model TP-A600 electronic balance to weigh the composition, and thioetherfloxacin according to 0.125g / m 3 With salicylic acid according to 0.025g / m 3 Prepare, mix and stir to make the original medicine, add 0.15g of the original medicine per cubic meter, add water to dilute to 1000 times to form a medicine solution, sprinkle the prepared medicine solution into the fish pond, cut off the water inlet and close the outlet water at the same time, Turn on the Rhea Machinery, the model is RY-PS-1.5, and the aerator with the specification of 1.5KW and 220V supplies oxygen to the fish pond; after 30 minutes, add fresh water, open the water at the same time, add medicine every other day, and operate 3 times in a row Continue feeding after the medication, 95% of the trout wounds heal and grow normally after three days, and the survival rate ...

Embodiment 2

[0022] In sunny weather, choose 10:00 spraying at a slightly lower ambient temperature, and use an electronic balance with a high-precision German sartorius imported model TP-A600 to weigh the composition, and thioetherfloxacin according to 0.12g / m 3 With salicylic acid according to 0.03g / m 3 Prepare, mix and stir to make the original medicine, add 0.15g of the original medicine per cubic meter, add water to dilute to 1000 times to form a medicine solution, sprinkle the prepared medicine solution into the fish pond, cut off the water inlet and close the outlet water at the same time, Turn on the Rhea Machinery, the model is RY-PS-1.5, and the aerator with the specification of 1.5KW and 220V supplies oxygen to the fish pond; after 30 minutes, add fresh water, open the water at the same time, add medicine every other day, and operate 3 times in a row Continue feeding after the medication, 85% of the trout wounds heal and grow normally after three days, and the survival rate of t...

Embodiment 3

[0024] In fine weather, choose 10:00 spraying at a slightly lower ambient temperature, and use an electronic balance of TP-A600 imported from Germany sartorius with high precision to weigh the composition. 3 With salicylic acid according to 0.04g / m 3 Prepare, mix and stir to make the original medicine, add 0.15g of the original medicine per cubic meter, add water to dilute to 1000 times to form a medicine solution, sprinkle the prepared medicine solution into the fish pond, cut off the water inlet and close the outlet water at the same time, Turn on Ruiya machinery, the model is RY-PS-1.5, and the aerator with the specification of 1.5KW and 220V supplies oxygen to the fish pond; after 40 minutes, add fresh water, open the water and add medicine every other day, and operate 5 times continuously; After feeding, 80% of the trout wounds healed and grew normally after three days, and the survival rate of the trout reached 75%.

Abstract

The invention discloses a composition for preventing and treating trout saprolegniasis. The composition comprises the following ingredients in parts by mass: 1 to 5 parts of diallyl-2,3-thioether and 0.2 to 1 part of salicylic acid. A preparing method comprises the following steps of: proportionally mixing the diallyl-2,3-thioether and the salicylic acid; stirring the mixture to be made into raw medicine; putting 0.15 to 0.25g of raw medicine in per cubic meter of area; adding water for diluting the solution to 1000 times to form medicine liquid; spreading the prepared medicine liquid into a fishpond; meanwhile, breaking the water supply, and turning on aeration equipment; injecting fresh water after 15 to 45min; adding the medicine once every other day; and performing continuous operation for 3 to 5 times. The diallyl-2,3-thioether and the salicylic acid are scientifically matched, so that the permeability of the composition is high; the sterilization effect is exponentially increased; the residue content of the diallyl-2,3-thioether and the salicylic acid in the environment and trout bodies is low; the medicine cost is low; and the composition can be used for replacing malachite green. Compared with traditional Chinese herbal medicine and Meibinglike in an aspect of the curative effect on the saprolegniasis, the composition has the advantages that the cure rate and the survival rate are high; and the national aquatic product fish medicine new standard is met.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to a composition for preventing and treating saprolegniasis of trout. Background technique [0002] Saprolegniasis is a disease caused by fungi infecting fish. The pathogens are some species of Saprolegniaceae, Saprolegnia and Cottonella. reproduce by means of spores. Saprolegniasis widely exists in fresh water or brackish water and moist soil, and saprophytes on dead organic matter; the occurrence of saprolegniasis is mainly due to secondary infection caused by "urgency", fish are only caused by crowding, moving, transportation or other environments Factors that cause body surface tissue injury and infection. At the initial stage of infection, no symptoms can be seen with the naked eye. At this time, the spores at the wound begin to germinate to form hyphae, and immerse in the tissue to grow continuously, secrete proteolytic enzymes to decompose host proteins, absorb nutrient...
