Preparation for preventing and treating roe saprolegniasis, and application thereof

Abstract

The invention relates to a preparation for preventing and controlling roe saprolegniasis. The preparation is prepared from one or more of ethylparaben, sodium butylparaben, an amidebactericide, Herba Plantaginis, Weeping Forsythia, Radix Scutellariae, dark plum, Herba Patriniae and Spica Prunellae. The invention also provides an application of the preparation. The preparation has the advantages of good prevention and treatment effect on saprolegniasis strains, great reduction of damages of medicines to roes, great reduction of the economic loss, and achieving of efficient and safe prevention and treatment effects. Above Chinese herbal medicines inhibit the production of harmful bacteria, and can reduce the resistance to antibiotics, tetracycline, quinolones and other drugs of bacteria, so obvious effects, no pollution, no poison and no toxic or side effects are reached when the Chinese herbal medicines are used to prevent and treat the roe saprolegniasis.

Description

technical field [0001] The invention relates to the technical field of fishery medicines, in particular to a preparation for preventing and treating saprolegniasis of fish eggs and its application. Background technique [0002] Saprolegnia is one of the susceptible pathogens on the surface and eggs of freshwater aquatic animals in my country. There are many types of saprolegnia, but Saprolegnia and Achlya are the main species of saprolegnia. Saprolegnia has no obvious selectivity to aquatic animals and seasons. Fish egg saprolegniasis is mainly aimed at sticky fish eggs. When unfertilized eggs die and are infected by Saprolegnia, the Saprolegnia hyphae will wrap other normal fish eggs, causing them to suffocate and die. Once infected fish are difficult to treat, it is particularly easy to infect injured fish and spread easily between injured fish. For a long time, the control of saprolegniasis has been one of the most difficult problems in the control of fish diseases. Th...

Problems solved by technology

In 2002, my country explicitly used malachite green as a banned drug in aquaculture because it was found to have problems such as "three causes", excessive residues, environmental pollution, and difficulty in degradation.

But generally speaking, there are still relatively few types of drugs that are effective, safe and non-resistant to fish eggs suffering from saprolegniasis at present. Mildew medicine is very urgent
