Embodiment 1

[0012] At the end of May 2009, the seedlings in the nursery room of the river crab farm in Tanghai County, Hebei Province suffered from severe ciliates. The seedlings had decreased food intake, difficulty in molting, and a certain proportion of them died. Changjia used the traditional method to spray formalin for treatment, and the concentration reached 20 parts per million. After 24 hours, the seedlings were checked, and the vigor of the seedlings was very poor, and there was no obvious change in the dead seedlings. After the applicant's guidance, first change out 50% of the indoor water for seedling cultivation, and then adopt the following method of the present invention to treat:

[0013] a. Sprinkle alum water in the water in the nursery room, so that the concentration of alum in the water reaches one part per million;

[0014] b. Two hours later, sprinkle veterinary zinc sulfate heptahydrate in the water in the nursery room to make the concentration of zinc sulfate in th...

Embodiment 2

[0018] In 2010, in the crab pond of Ding Quanlai, a farmer from No. 4 Farm in Tanghai County, Hebei Province, within half a month after putting the megalopa larvae in, the juvenile crabs were seriously unable to go ashore, and many died. A large number of ciliates are parasitized in the hair, gills, etc. Afterwards, through the applicant's guidance, the pond is replenished with new water, so that the water level is increased by about 15 centimeters, and then the following method of the present invention is adopted for treatment:

[0019] a. Sprinkle alum water in the pond, make the concentration of alum in the water reach two parts per million;

[0020] b. Two hours later, sprinkle veterinary zinc sulfate heptahydrate in the pond again, so that the concentration of zinc sulfate in the water reaches one part per million;

[0021] c. While spraying the water body with the drug, add veterinary nystatin water agent to the bait, and add 10 grams of veterinary nystatin in terms of ...

Abstract

The invention relates to a river crab culture technique, in particular to a novel method for treating balantidosis of river crab, which comprises the following steps that: a. liquid alum is used for sprinkling a disease pool, and concentration of alum in the pool water reaches one to two millionth; b. heptahydrate zinc sulphate for animals are sprinkled two hours later, and the concentration of zinc sulphate in the pool water reaches one millionth; c. animal Nysfungin powder or aqua is added into baits while sprinkling the chemicals, and 5g to 10g of animal Nysfungin which is calculated by mass of dry powder is added into every ton of feed. Compared with the prior art, the novel method is environment-friendly, has small harm on the environment and has remarkable control and killing effect.

Description

Technical field: [0001] The invention relates to the culture technology of river crabs, in particular to a new method for treating ciliates of river crabs. Background technique: [0002] The ciliate disease of river crab mainly refers to the parasitism of the plastron, appendages and gills of river crabs, such as polymycosis, sclerotia, and gills, etc., resulting in sluggish movement, difficulty breathing, loss of appetite or even stop eating, and finally due to malnutrition, Dying due to inability to moult, is seriously harmful to river crab nauplius, megalopa, and crab seedlings below the third stage, often resulting in a large proportion of deaths. Known treatment ciliate disease has three kinds of methods, and the one, soaks and splashes with malachite green, but malachite green side effect is big; Consumption is big, also very big to people and environment harm, and application is greatly restricted; The 3rd, treat with compound zinc sulfate powder type I or compound z...
