The invention relates to a Chinese
herb compound preparation for preventing and controlling the hepatopancreatic
necrosis disease in river crab culture, and belongs to the technical field of
aquaculture. A preparing method of the Chinese
herb compound preparation mainly includes the steps that Lonicera
japonica,
Rhus chinensis Mill. and
Artemisia apiacea are taken and weighed in proportion, water is added for decoction, decoction liquid is evenly mixed with
salicylic acid,
citric acid and polyhexamethylene biguanidine
hydrochloride according to the weight proportion, split charging is conducted, and finally packaging and warehousing are conducted. The Chinese
herb plants safe and nontoxic to river crabs are adopted and cooperate with various substances such as
organic acid and environment-friendly macromolecular
fungicide, and the Chinese herb compound preparation integrates the functions of resisting
bacteria and viruses, killing microsporidia, relieving invasion of toxins in a
culture environment, preventing the
disease and promoting growth, contains definite ingredients, has a wide effect, can be directly splashed, and is convenient to use, high in
bioavailability and free of influences of environmental conditions; after the Chinese herb compound preparation is used, the river crab culture
ecological environment can be rapidly remediated, heavy
metal and
pesticide residues in the
culture environment can be rapidly reduced, the quantity of microsporidia,
bacteria and viruses in the
culture environment can be effectively reduced, the incidence probability of the hepatopancreatic
necrosis disease of river crabs can be reduced,
body tissue can be protected, growth can be promoted, and the river crab culture yield and quality can be improved.
