Anyone who even once tried crawfish meat, knows what it is tasty and tender.Currently, the breeding of fauna in Russia almost mastered.Nevertheless, the demand for the product is high.Some villagers manage to make a good fishing crabs in their natural habitat, however, so they have a negative impact on the natural populations of these animals.This fishing is inherently poaching.Even before the revolution in Russia has successfully engaged in breeding of crayfish in an artificial environment.The resulting meat was exported to many European countries.The current situation is such that the main suppliers of the product on the world market - Turkey, China and Spain - countries where previously no cancers were performed.
Pond
divorce crayfish in the ponds?To begin, clean the pond if it silted or swamped.Keep away from cancers carp, carp and other non-predatory fish.However, keep in mind that such a business would suffer with the arrival of winter.This is due to the fact that cancers tend to hibernate if the temperature falls below fifteen degrees Celsius.In a state of suspended animation, they cease to consume food and, therefore, does not increase the weight.If the pond and all chilled to the bottom of your pets die.
However, many businesses are wondering about how to breed crayfish in the ponds because these waters are the most resistant aqua systems, self-cleaning and self-renewal.Thus there is good opportunity to save money on feed, filters and aerators.Cancers are happy to feed on plankton, algae and insect larvae.The disadvantage is that the increase in the natural environment of these animals takes place fast enough.Trading mass recruited about in the fifth year of life.Thus, the business will start to generate revenue in just six years.Attractively that initial investment is practically not required.
Aquarium

The only drawback of the described business are its small volumes.Industrial scale is difficult to achieve because of the limited area of breeding.However, some owners have figured out how to breed crayfish in a tank to get maximum profit.At home, they grow to the larva "fingerlings" and then release them in a natural or artificial reservoir.This solution manages to organize a successful business.But how to breed crayfish at home to minimize the losses?In the first place should be control over the quality of water.In this case, not so much die larvae, moreover, they grow much faster.

Features reproduction
Mating takes place in September and October.Males are capable of fertilizing up to two females in a row.If they will fall a third, they simply eat.This fact is due to the optimum ratio of individuals of different sex in the water (two females to one male).
First caviar is an animal under the shell.After postponing it secured under the tail.To properly developed embryos, the female constantly washes the eggs, thus effectively clearing it.Two months going pecking maggots.Another three weeks they rest under the tail of the female to avoid many dangers.After this time, quite independent crustaceans leave the cozy haven for all.The natural habitat of each female can grow up to twelve larvae.More than twenty offspring a year she can not be.As for the home environment, this number actually tripled.
Molting
Young copepods in the first twelve months of his life shed eight times.In the next two years they will have to go through it before seven to nine times.Adults shed much less often - once or twice every 12 months.During this period the old shell is simply dumped, as it becomes a tight fit for the growing animal.
divorce cancers right?We must pay special attention to them during the molting when the animal is particularly vulnerable to attack not only the predatory fish and birds, but also their relatives.

Places breeding
If you are serious and plan to turn the crayfish breeding in a highly profitable business, it is advisable to organize the farm.Only in this way will be able to set up production of tasty products on a commercial scale.This will require the following:
- incubation tanks. It is very important that they are equipped with powerful heaters, compressors and filtration system.
- Pools where bred crayfish, which have become independent individuals. There they must grow to fingerling stage.
- Covered ponds. There should be at least two, but it is better to try to organize more.Thus, the business will grow faster.The minimum area of the pond should be 25 square meters.m and depth - 2 m. Note that in ponds elongated better gas exchange occurs.It is recommended that water was flowing in them.That is why it is important to close a river.If this is not possible on your farm drilled several water wells.
At the bottom of bodies of water is required to place a shelter for crabs.They can serve as pieces of pipes made of plastic or ceramic, stones, driftwood, etc.

more isolated lake and river crayfish.The first are most suitable for home based business because they do not hibernate and can reach impressive sizes.However, there is one drawback: lake crayfish are very capricious.For their successful breeding and content need a warm room area of not less than twenty square meters.Crayfish are not so demanding, but are smaller, respectively, and they are not so expensive.
When purchasing animals have overlooked the fact that in the same pond do not live crabs of different species.

Then proceed to the organization of sanitation.To this may be a conventional pipe which closes the top valve.On the tube put the net, so that cancers were not able to leave the body of water by a peculiar tunnel.
most exciting time - filling the pit with water, and the launch of the first cancers.Now comes the period of constant concern for the habitat of animals.Do not forget to change the water every two to three weeks.It is best to update the pond about a third, not much to disrupt the steady climate.
profitable to breed crayfish?
