Abstract

Provided is a breeding method of leeches in a barrel-type net cage. The breeding method comprises the following steps of (1) arrangement of the barrel-type breeding net cage, (2) arrangement of a breeding pond, (3) selection of leech larvae, (4) putting of the leech larvae, (5) feeding of the leeches, (6) water quality management and (7) harvesting of the leeches. The method overcomes the defectsof low survival rate, low yield and the like of leeches bred by means of existing leech breeding methods.

Description

technical field [0001] The invention relates to the technical field of breeding, in particular to a method for breeding leeches. Background technique [0002] Leeches, commonly known as leeches, belong to the family Hirudidae. Leeches are bitter, salty, and flat in nature. They have high medicinal value and are dried as a whole. Clinically, leeches can be used for the following symptoms: ① treatment of cerebral infarction and cerebral hemorrhage; ② treatment of coronary heart disease, angina pectoris, acute myocardial infarction and pulmonary heart disease; ③ treatment of disseminated intravascular coagulation (DIC); ④ Treatment of vascular embolism diseases, such as phlebitis, vasculitis obliterans, thrombotic arteritis, etc.; ⑤ treatment of hyperlipidemia; . [0003] With the in-depth development of the medicinal value of leech, its market demand potential is huge, and the prospect of leech breeding is good. At present, due to the influence of factors such as technical...
