The idea of \u200b\u200bgrown cancer can come to mind for various reasons. This and the desire to earn, and just tasty eat an environmentally friendly product. The meat of these arthropods is not only a delicacy, but also a useful product. It contains minimum calories and maximum the necessary organism of elements: sulfur, calcium, vitamins E and group V. Drain cancers in ponds (natural or artificial) or in aquariums.
1
So that the cancelors have taken root and wellhold, the reservoir should be deep from 1.5 m to 3 m. The bottom of its sandy or stony. There must also be conditions so that the animals can dug holes. The optimal number of ponds is at least three squares at least 30 m2. Two of them are designed for fattening, and one for growing segments.
2
The insulation of the basin provides accelerated cancer growth, because with negative temperatures, crustaceans flow into the hibernation or dying.
3
An indicator of purity and acidity of water is equally important. For this, water should be flowing, and the pH range between 6.5 and 8.0. You can provide this by the drainage system and pumps. Water change every 2-3 weeks, but no more than 30%, so as not to disturb the natural microclimate.
4
Buy the uterine population from specialized commercial enterprises. Inseculate the pond with adults with caviar at night, trying not to damage the offspring during transportation. You can also run the fry, but not later than the second half of August so that they manage to acclimatize. At each male should have two or three females, which he later fertilized. The landing density is small - six to eight pieces per 1 m2.
5
Large cancers are better to contain separately from the young, as they are able to devour their offspring. Only for 3-4 years of life, animals reaches the commodity mass. Feeded in captivity in captivity, crushed vegetables and grain, algae and worms that can be found in the reservoir. The feeder produces at sunset, because raks are night inhabitants.
6
The breeding of cancers in artificial aquariums guarantees a continuous process of animal growth. Capacities purchase on the market or make themselves from non-toxic material: plastic, polypropylene or plexiglass. Dno arrange sand and small boulders to create pets the familiar setting.
7
In addition, you will need aerials for air supply, oxygenator, salter, thermometer and oximeter, heaters and water filtration system.
8
In the aquariums, cancers are linked more than once a year, and 3-4. This means that they will rapidly raise the vehicles than their relatives from open reservoirs (raks are growing only during the shell dropping).
9
Regardless of how you grow crayfish, they need to be protected from diseases and infections. Strictly control the temperature mode, change the water on time, saturating it with oxygen. It is impossible to overflow the livestock.
As you can see, growing cancers in open reservoirs - less expensive, but the animals grow slower than in the aquariums, because no one has canceled seasonality (at least in the middle lane of Russia). Plus, this business requires considerable investments, the payback period of which is 3-4 years.
