Breeding and growing crayfish at home is not uncommon and has been practiced for a long time. The difference is only in scale: for whom is this business, and who does it for their own pleasure.
Place for crawfish breeding
For breeding cancers you can use both aquariums and whole pools. Some arrange whole ponds. To install aquariums you will need a room with good heating. And inside the aquariums, arrange hollow stones and aquatic plants. Compulsory filtration systems and air compressors .
The pool is arranged in a specially prepared pit in which a polypropylene bowl is installed. A pneumatic compressor produces aeration. In swimming pools are usually grown from eggs of sagolets.
True, for the artificial breeding of a large number of cancers you will need a pond device, which is convenient in case you have a large free area. If the depth of the basin does not usually exceed 70 centimeters, the pond should have as much as two meters. And the area is no longer 2 or 6 meters, but 0.3 hectares. That the water does not leave the pond, its bottom should be covered with a waterproof film. But at the same time it is necessary to conduct two pipes - drainage and for the supply of fresh water. In the pond you need to put aquatic plants, and enrich the shore with trees and shrubs.
In order to start breeding crayfish, it is necessary to select sexually mature individuals, which are 4-5 years old. It is known that if crayfish get proper care, they can live up to 25 years, and one female can give you up to 30 crayfish within one year.
Types of cancers and ways of breeding them
Dilution and maintenance of crayfish should take place in fresh water. They mate mainly in the fall. And in the spring you can observe how small crustaceans appear from the eggs.
Although at home, if you are breeding aquarium crayfish, the process of developing eggs can be accelerated and shortened to a period of up to three months. The water temperature for river animals should not exceed 24 degrees. The activity of animals is manifested at night, while in the daytime they sleep more in their burrows.
Feed the same crayfish need fresh aquatic plants, shellfish, bloodworms, insects, corpses of fish, earthworms, as well as frogs. Adult individuals eat mostly in the warm season, and in the winter they become passive, half asleep, and accordingly, eat much less.
If crayfish breeding occurs in aquariums or artificial ponds, where the water temperature does not drop below 15 degrees, you need to feed the crayfish all year round. Females with eggs are planted in the pond only when the water warms up to 20 degrees. It is necessary to look at the appearance of future mothers - if they have foam at the mouth and claws are lowered, they are planted in a separate pool, where water exchange takes place at a rate of 0.6 - 0.7 l / min.
When the larvae hatched from the eggs become independent, the females are planted in a pond where they can already shed and, possibly, mate with males to continue the offspring. The independence of the larvae can be determined by the fact that they cease to gather in a heap, do not hide in a period of danger under the mother's tail, and also move quickly in search of food on the bottom of their home.
After reaching the age of sagolets - 90 days, they can be transplanted to the pool in order that they continue their growth and development in natural conditions.
The breeding of blue Cuban cancer, which likes to be in the light for at least 10 hours, and also hang on aquatic plants , is quite simple. They feed the same way as other crayfish, only the food should be in the aquarium 24 hours a day. It breeds all year round. And the maturation period of eggs at a water temperature of 26-27 degrees takes place in three weeks.
