Chinese herb compound preparation for preventing and controlling hepatopancreatic necrosis disease in river crab culture

Abstract

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.

Description

technical field [0001] The invention relates to a Chinese herbal medicine compound preparation used for preventing and controlling water slug disease in river crab culture, and belongs to the technical field of aquaculture. Background technique [0002] With the rapid development of shrimp and crab aquaculture, shrimp and crab diseases have the characteristics of high hazard, multiple occurrence and complexity, which affect the healthy development of shrimp and crab aquaculture. In recent years, the crab farming area in the Yangtze River Basin has appeared the disease known as "water flat" by crab farmers. The incidence rate is as high as 15% to 50%, and it is still getting worse. "Water deflated child" disease is a common name for river crab hepatopancreas necrosis, and the most important feature of diseased crabs is hepatopancreas necrosis. In 2015, the proportion of "water sluggish" disease in river crab breeding was large, involving a wide range (Jiangsu Xinghua, Gaochu...
