Dear Leech Farmers,
My field of expertise is the systematics of leeches but I have some
experience in medicinal leech aquaculture. There is the extensive
Russian literature on breeding leeches but I suppose the most available
and helpful article on leech aquaculture is
R.W. Davies, N.J.McLoughlin. The effects of feeding regime on the
growth and reproduction of the medicinal leech Hirudo medicinalis.
Freshwater biology (1996) 36, 563-568.
See also references in the article.
Here is the general information which can help you to begin breeding
leeches immediately. Leeches should be maintained in aquaria (100 c.c.
per a leech) containing dechlorinated tap water at 20 - 25 C. Young
leeches are fed every 20 days with homogenated fresh bovine blood
using a bovine intestine. It is necessary to make blood sausages and to
place them in an aquarium. Leeches are maintained singly for a months
before the copulation and then two individuals per an aquarium during the
copulation for a month. Medicinal leeches deposit cocoons in wet
substrate like soil (not in water!). The best substrate for cocoon
deposition is peat. Leeches produce much more cocoons when
maintained singly in a container. I think this is the basic information you
must know to breed medicinal leeches.
If you have any further questions please let me know. I will be glad
to help you.
