[0005] At present, in order to control the occurrence of outbreaks of rotifers and protozoan diseases in aquaculture water, farmers mostly use chemical drugs or pesticides to kill rotifers in the whole pool, which can effectively kill rotifers in a short time. However, due to the relatively large toxic and side effects of these drugs, they will cause greater damage to the cultured shrimp and crabs, and a little carelessness will cause a large number of deaths of the cultured shrimps and crabs; in addition, these drugs have a killing effect on the resting eggs of rotifers Limited, rotifers tend to reproduce in large numbers and cause diseases after a period of time after treatment

Abstract
The invention relates to a compound medicinal composition for destroying and expelling rotifers and protozoa and a preparation method thereof, which belong to the field of veterinary medicament. The compound medicinal composition comprises rhizome zingiberis, stone-like omphalia, areca-nut, common carpesium fruit, male fern rhizome, the tuber of stemona, kuh-seng and anhydrous cupric sulfate. Thecompound medicinal composition of the invention can effectively control fulminant rotifers and protozoa diseases in culture ponds of fishes, shrimps and crabs, and particularly can avoid the shrimps and the crabs hypoxia caused by the fulminant rotifers and protozoa diseases in the culture ponds of the shrimps and the crabs; and at the same time, the compound medicinal composition can kill the protozoa such as chilodonella, the rotifers and the like and the resting eggs of the rotifers. The compound medicinal composition is green, safe and environmentally-friendly, and has no toxic or side effect on the shrimps and the crabs; the compound medicinal composition does not generate medicament residue harm to human health and medicament resistance, and does not pollute the environment; and in the compound medicinal composition, 95 percent of medicament grain has the diameter of 50 microns, the effective component of the medicament can be released quickly, the medicament dosage can be reduced, the medicament resource is saved, and the cost is reduced.
Description
technical field [0001] The invention relates to a compound medicinal composition for expelling and killing rotifers and protozoa and a preparation method thereof, belonging to the field of veterinary medicine. Background technique [0002] Rotifers belong to the phylum Rotifera, and are small in size. They are an important part of zooplankton in water bodies. In fish ponds and sewage ponds, the biomass of rotifers often occupies the first place in the biomass of zooplankton. In fishery production, rotifer is a good animal natural bait, and most of the fry are in the stage of transformation from endogenous nutrition to exogenous nutrition, and rotifer is the most palatable high-quality bait. [0003] However, in recent years, with the increasing scale and stocking density of aquaculture, in order to pursue higher aquaculture production and improve economic benefits, farmers have been feeding a large number of high-quality compound feeds, resulting in an increasing load on th...
