Leech facts :
650 known leech species
Only 5 species
Largest ever discover measured 1.5 feats
Leech has 32 brains
Leech lay babies within cocoon - quantities as many as 300
As hermaphrodites, leeches have both male and female sex organs. Like the earthworms they also have a clitellum, a region of thickened skin which is only obvious during the reproductive period.
Mating involves the intertwining of bodies where each deposits sperm in the other’s clitellar area.
Rhyncobdellids have no penis but produce sharp packages of sperm which are forced through the body wall.
The sperm then make their way to the ovaries where fertilization takes place. The clitella secretes a tough gelatinous cocoon which contains nutrients, and it is in this that the eggs are deposited.
The leech shrugs itself free of the cocoon, sealing it as it passes over the head.
The cocoon is either buried or attached to a rock, log or leaf and dries to a foamy crust.
After several weeks or months, the young emerge as miniature adults.
Studies show that the cocoons are capable of surviving the digestive system of a duck.
Leeches die after one or two bouts of reproduction.

Bite of a leech is painless due to its own anesthetic.
Hirudo injects an anti-coagulant serum into the victim to prevent the blood clotting.
The leech will gorge itself until it has had its fill and then just fall of.
After the Hirudo leech drops off the wound it leaves will bleed, on average, for ten hours.
Hirudo Medicinalis is the leech mostly used in plastic and reconstructive surgery.
By extracting the anti - clotting serum from the leech researchers are isolating new pharmaceutical compounds for eventual treatment of heart diseases.
What leech farming?
-Give nature a helping hand
-Protect endanger species and prevent disruption of natural ecosystem.
-Provide sufficient and high quality leeches for the help of medical field.

Why leech farming?
-Breeding multiplication factor up to 300x
-Low cost start - up and high return
-Require minimum space/area
-Low cost feed - eel, vegetation, root, peat, cat, fish, coconut, moss
-Require minimum maintenance
-High demand and varieties of usage
Return of Investment
Given capital of RM3000 (USD833.00)Conversion rate : 3.6
Mature leech : RM1.60 - RM5.00 (depend of size of pool, material used, and location)
Leech Food : RM600 for 6 months (Again depend of type of food, avaibility and size of tank)
Facts about Leech Farming
Leech grow & mature periods : 6 - 12 months
Breeding factor : 200x - 300x
Example investment calculation
Mature leech = RM4.00/pc
Quantity of 500 mature leeches : RM4.00 x 500 = RM2000
Leech pool and setup cost = RM600 using poly tank with outdoor canopy
12 Months food cost for 500 leeches : RM33 x 12 = RM400 (Diet dependant)
Your total investment will be (RM2000+RM600+RM400) = RM3000
What is your return?
Now of leech after 12 months = (500x300) = 150000
Since leeches can able to multiply by 200x to 300x
Let say the Surviving rate ( Yield) = 50 %
The mature leech produce = 150,000x 50% = 75, 000 leeches
The gross profit will be = 75,000 x RM1.50(vary according market price) = RM112,500 (USD31,250)
Your Return of Investment = 112,500 - 3,000 = RM 109,500.00
