Problems solved by technology

Breeding in ponds and paddy fields belongs to extensive breeding. It is not easy to achieve large-scale leech breeding and breeding to meet the needs of pharmaceutical production, and water farming is not conducive to the observation and management of leeches
The disadvantage is that the breeding density is too small and the feed utilization rate is low, which virtually increases the breeding cost, which is not conducive to the domestication of leeches, disease control and prevention of natural enemies, so the benefits of leech breeding are still low

Embodiment Construction

[0035] The method for raising leech in drought, comprises the steps:

[0036] (1), the selection of leech seedlings: 20kg of leech seedlings randomly collected from ponds and paddy fields are roughly evenly divided into ten parts and put in white pots, obviously injured and inactive are removed, and the selected seedlings are put into Disinfect and soak in 0.3ppm furazolidone solution for 1.5 hours, then put it into clear water for 15 minutes, and finally obtain 19.8kg of high-quality leeches, which are roughly divided into seed leeches, hatching stages, early leeches, and late leeches according to different growth stages. And into leeches, the weights of each period are respectively 17kg, 0.2kg, 0.5kg, 0.9kg, 1.2kg, and then put into the corresponding breeding bed at a breeding density of 0.02~2.3 kg / square meter;

[0037] (2) Establishment of the breeding bed: the bottom of the breeding bed is raised with a very dense stainless steel net, about 5cm from the ground, and is di...

Abstract

The invention provides a cultivation method of leeches in a drought environment, which is suitable for scale cultivation and has lower cost and high benefit. The method comprises the steps of placing leeches on different cultivation beds for cultivation in a drought environment according to different growth phases, differentially treating management areas at various growth phases and matching with fermented rotten feed. The invention can greatly increase the cultivation density, improve the yield, save the collection cost, improve the effective utilization rate of resource, be not limited by natural environment and really realize intensified and scale leech cultivation.

Description

technical field [0001] The invention relates to a method for cultivating leeches, in particular to a method for raising leeches under dry conditions. Background technique [0002] Leech is a general term for the class Hirrdinea of ​​the phylum Annelida in animal classification, commonly known as leeches. There are about 500 species known in the world, divided into 4 orders. There are 2 orders, 8 families, 33 genera and nearly 100 species in my country. Among them, there are some species in the order Anoscillidae, Phydrodidae, Pelidae and Licodidae which are more directly related to humans. Leeches are important traditional Chinese medicinal materials, especially for the preparation of Chinese patent medicines for the treatment of cardiovascular and cerebrovascular diseases. It is one of the most popular Chinese herbal medicines, and it also has broad application prospects in modern medicine. However, in recent years, the living environment of leeches has been seriously p...
