Embodiment Construction

[0021] The artificial breeding method of the wide-body golden leech provided by the present invention comprises:

[0022] (1) Natural development law and growth habit of leeches broad-bodied

[0023] Wide-bodied leech, commonly known as leech, grows up, slightly spindle-shaped, flat, 6-13cm long, and 0.8-2cm wide. The back is usually dark green, with 5 vertical lines composed of fine yellow and black spots, and one darker in the dorsal midline. The ventral surface is light yellow, mixed with many irregular tea-green spots. The number of body rings is 107, and the annulus obviously accounts for 15 rings. The male genital pores are between the 33rd and 34th ring grooves, and the female genital pores are between the 38th and 39th ring grooves. Eyes 5 pairs in an arc. The front sucker is small and the teeth are underdeveloped.

[0024] It lives in paddy fields, rivers, and lakes. It does not suck blood, but feeds on plankton, small insects, larvae of molluscs, and humus on mu...

Abstract

The artificial breeding method of wide-body golden-thread leech includes the following steps: building artificial breeding pool of wide-body golden-thread leech, seed leech selection, culturing larvaand cultivation of the wide-body golden-thread leech in large pool. Its propagation coefficient is obviously raised and stable, and is above 1:80, generally. The breeding method only has requirementsfor 2-3 years.

Description

1. Technical field [0001] The invention relates to an artificial breeding method for wide-bodied golden leech, which is specially used for artificially breeding wide-bodied golden leech. 2. Background technology [0002] Wide-bodied golden leech Whitmania pigra Whitman belongs to the phylum Annelids, class Hirudophylum, and is a species of traditional Chinese medicine leeches. There are about 400-500 species of leeches in the world, and 89 species have been found in my country. Although there are many kinds of leeches used as medical research so far, only three kinds of wide-body golden line leeches, Japanese medical leeches and brown leeches are recorded in "The Pharmacopoeia of the People's Republic of China" (2000 edition). [0003] As a traditional Chinese medicine in the great treasure house of Chinese medicine, leeches are traditionally used as medicine after being processed from dried worm bodies. It is recorded in the famous Chinese medical book "Shen Nong's Materi...
