A compound preparation for treating large yellow croaker irritating Cryptocaryoniasis

Abstract

The present invention relates to a compound preparation for treating large yellow croaker irritating cryptocystosis and its application. The compound preparation is composed of 10 wt% to 15 wt% of nitazoxanide and 5 wt% to 7 wt% of copper sulfate , oxytetracycline 25 wt%~30 wt%, dissolving agent 48%~60%, the sum of the above raw materials is 100%. The method of use is: after the diagnosis of cryptocystosis irritant, sprinkle the above compound preparation in an amount of 8~10 g / m3, and soak in the bath continuously for 3 days, which can effectively cure cryptocystosis irritant of large yellow croaker and prevent secondary infection of bacteria . The invention has the advantages of simple preparation method and convenient use, can significantly reduce the death rate of large yellow croaker stimulated by cryptocystosis, and improve the economic benefits of breeding.

Description

technical field

[0001] The invention belongs to the technical field of aquaculture, and in particular relates to a compound preparation for treating large yellow croaker stimulating Cryptocaryoniasis and its application method. Background technique

[0002] Stimulate Cryptocaryon ( Cryptocaryon irritans Brown), also known as sea water melon worm ( Ichthyophthirius marinus ), belonging to the phylum Protozoa, the subphylum Cilia, the class Oligomembrane, the subclass Hymenostomum, the order Hymenostomum, the family Notchidae, and the genus Cryptocaryon. In addition to macular bluefish ( Siganus oramin ) and a few species of fish, Cryptocaryon irritans can infect most bony fishes in seawater, and easily cause a large number of deaths, which is a serious hazard to seawater aquaculture. In my country large yellow croaker ( Pseudosciaena crocea ) in aquaculture production, the incidence and mortality rate of Cryptocaryoniasis is as high as 60% to 100%, and the mortality r...
