Culture method for Poecilobdella manillensis

Abstract

The invention discloses a culture method for Poecilobdella manillensis. The method comprises the following steps: (1) preparing culture cages: placing net cages into glass jars, and carrying out disinfecting, thereby preparing the culture cages; (2) stocking Poecilobdella manillensis offspring into the culture cages, adding water into the culture cages, changing the water once every 2 to 3 days, feeding feed to the culture cages, and carrying out culturing at the ambient temperature of 25 DEG C to 26 DEG C and the relative humidity of 50% to 60%; and (3) carrying out harvesting after carrying out culturing for 4 to 5 months. The culture method disclosed by the invention is high in yield and good in economic benefit.

Description

technical field [0001] The invention relates to a method for cultivating Hirudo phenanthae. Background technique [0002] Philippine leech (PoecilobdellamanillensisLesson.), commonly known as Phnom Penh leech, belongs to the phylum Annelida, the class Hirudinea, the order Arhynchobdellida Blanchard, the family HirudinidaeWhitman, and the genus Poecilobdella Blanchard. The larger species of blood-sucking leeches live in rice fields, ditches, rivers or ponds, and live by sucking the blood of humans and vertebrates (such as cows, frogs, etc.). They are mainly distributed in Guangxi, Guangdong and other regions in southern China A few provinces such as Hainan, and abroad are mainly distributed in Southeast Asia such as the Philippines, Thailand, and Vietnam below an altitude of 500m. [0003] Because the salivary gland and the saliva it secretes are rich in the world's strongest antithrombin active substance, namely natural hirudin, it has attracted people's attention. For a l...

Problems solved by technology

For a long time, the extensive use of quicklime in agricultural production to improve the soil and the application of chemical fertilizers and pesticides, coupled with the discharge of industrial waste, have seriously polluted the water body, making the living space of the philippines smaller and smaller, and the wild resources are getting less and less. The method of obtaining leeches from the natural environment cannot meet the requirements at all, and artificial breeding is required

[0004] The current artificial breeding methods are all cultivated in outdoor natural environments, such as cement ponds, ponds or furrows. It is difficult to effectively control the various conditions of breeding, and the input-output ratio is low. At the same time, it is greatly affected by the natural
