Leeches - Life
The long-awaited report from the piyavochnoy farm. You will learn how to live leeches in captivity,
what they eat, as multiply. For the first time we managed to remove the unique frames
Birth leeches in the wild and in captivity.
Today we will tell you about the International Center of Medical leeches, established on the basis formed in 1937 in association Medpiyavka ", which was engaged in the content of leeches in artificial ponds holiday village specific (Moscow region).
At 2500 sq.. m. located manufacturing facilities to grow more than 3 500 000 medicinal leeches and manufacture of cosmetic products.
Total Science 400 known species of leeches, which look about the same and differ mainly coloring. Leeches are black, greenish or brownish. Russian name of these worms yurkih indicates their ability to "dig" in the body of the victim and suck blood.
Leeches live in three-liter jar. Nothing better as a house for them, not invented. Piyavkovod should ensure that the vessel with leeches was always closed dense white cloth, which is tightly knotted.
Leeches extremely mobile and often tend to crawl out of the water. Therefore, they can easily leave the container in which are stored. Sometime the event of escape.
At leech 10 eyes, but a holistic picture a leech does not perceive. Despite the apparent primitiveness of sensory perception leeches, they are perfectly oriented in space. Smell, taste and touch, they have developed extraordinarily, which contributes to their success in the search for victims. First of all leeches are perfectly responsive to the smells emanating from the objects immersed in water. Smelly water leeches do not carry.
Slow, lacking sharpness of motion can see all the body leeches. On the back against the dark - bright orange blotches form a curlicue in the form of two bands. On each side - black edging. Abdomen tender, light-olive color with black edging. The body of an ordinary medical leeches consists of 102 rings. The dorsal side of the ring covered with many small papillae. On the ventral side of the papillae is much smaller and are less noticeable.
But for the harmless foreign leeches lies the beauty of its secret weapon - anterior suckers, seemingly unnoticed. Large, fearsome rear sucker does not cause any physical harm, but lurk in the depths of the anterior mandible, geometrically arranged to mark the prestigious company of the automobile world - Mercedes. In each jaw has 90 teeth, totaling 270. Here it is - deceit.
Record the maximum size of leeches, grown in the center - 35 centimeters in length. We leeches in the photo still all ahead.
Bitten by a leech - like nettles stung. Sting of the same horse-fly or ant much painful. In the saliva of leeches contains painkillers (analgesics). Leech only feeds on blood. Hematophagous, that is, a vampire.
The epidermal layer is covered with leeches special film - cuticle. The cuticle is transparent, it performs a protective function and grows continuously, periodically updated in the process of molting. In a normal molt occurs in leeches every 2-3 days.
Dropped film resemble white flakes or small white blankets. They litter the bottom of the vessels used for storage of leeches, and therefore must be regularly removed, as water periodically painted on the products of digestion. Water was changed twice a week.
Water is specially prepared: advocating not less than a day, cleaned of contaminants and heavy metals. After purification and transmission control, the water is heated to the desired temperature and enters into a common network to leeches.
Leeches shit up to several times per day, why the water in the vessel, which stores used leeches occasionally painted. What happens from time to time, clogging water leeches do not cause any harm, if the water is systematically changed.
The most important condition for the rapid growth of full-fledged medicinal leeches is their regular feeding of fresh blood, which is purchased from slaughterhouses.
To leeches liked to eat, they trail the film, which they bite through the habits and suck blood.
During the growth of a leech fed every six to eight weeks.
After the leeches have grown and otgolodali not less than three months, they gather in the series and send the certification and the further they go on sale or used in the manufacture of cosmetics. The Center operates an accredited laboratory quality control department. But more about that tomorrow.
During one feeding leeches sucking up to five times more sovego weight, after which she can not have three or four months, maximum a year. After eating like a leech on a solid muscle bag filled with blood. In her digestive tract contains special substances, preservatives blood from rotting, who canned it in such a way that blood is always full and kept for a long time.
Cram leech is usually for 15-20 minutes. A sign that leeches are fed, there is foam.
Leeches communicate with each other rarely, only during mating. And then, most likely, by necessity, to avoid extinction. Suitable for reproduction, that is thoroughly well-fed and have achieved a certain sized leeches are called sows.
