Compound Chinese herbal medicine preparation for preventing and treating oosperm block saprolegniasis of spot furcate-tail leiocassis longirostris

Abstract

The invention relates to a compound Chinese herbal medicine preparation, in particular to a compound Chinese herbal medicine preparation for preventing and treating the oosperm block saprolegniasis of spot furcate-tail leiocassis longirostris, which is applied to the incubation process of fish class artificial propagation oosperm. The compound Chinese herbal medicine preparation respectively comprises the following components by weight percent: 14.5% to 20% of kuhseng, 13.5% to 18% of cnidium fruit, 8% to 13% of aloe, 13.5% to 18% of kaempferia galamga, 13.5% to 18% of broom cypress fruit, 8% to 13% of bunge prickly ash, 8% to 13% of nutgall and 14.5% to 20% of smilax glabra roxb. The invention has the following effects: 1, the raw materials are matched according to the matching principle of Chinese herbal medicines, the preparation reinforces the medicine effect, does not damage the embryonic development of the fish class oosperm and has especially obvious effect for preventing and treating the saprolegniasis in the incubation process of the oosperm; 2, the medicines are degradable under the condition of a water body, have no toxic or side effect and do not influence the normal embryonic development of roe, and the muscle of incubated seed bodies does not generate heavy metal and medicine residues; 3, the invention has no corrosiveness and simple and safe using method; and 4, surface source environmental contamination to the water body is not generated.

Description

technical field [0001] The invention relates to a compound Chinese herbal medicine preparation, in particular to a compound Chinese herbal medicine preparation for preventing and treating saprolegniasis of fertilized eggs of channel catfish in the hatching process of fish artificially propagated fertilized eggs. technical background [0002] In the hatching process of artificially propagated fertilized eggs of fish, saprolegniasis is one of the fungal diseases that are more common and more serious when hatching fish fry from artificially propagated fertilized eggs. Especially during the incubation period of fertilized egg masses of channel catfish, saprolegniasis is particularly prone to occur, and the transmission speed is extremely fast, and sometimes all fertilized eggs can be infected with embryo development and die within a few hours, resulting in failure of fry hatching, which is more harmful to fish fry reproduction. [0003] At present, there are many drugs for the p...

Problems solved by technology

Now there are many drugs used for hatching, such as formalin, shuimeijing, shuimeiling, iodine preparations, chlorine dioxide, etc., which have certain effects but are unstable, have side effects and corrosiveness, and are harmful to the embryonic development and hatching of fertilized eggs. Negative impacts from water pollution sources, pH value, commercial fish food hygiene and safety, etc.
