CREATION OF CANCERS IN HOME CONDITIONS WITH MINIMUM INVESTMENTS
Breeding crayfish at home brings a steady income, which is secured by stable demand. Competition in this business is weak. Large fish farms do not want to engage in crustaceans closely, because at the initial stage, payback does not give the desired profit with large amounts of investment. It is quite difficult to implement large lots in a short time: the most delicate cancer meat is an expensive product that can be offered to a limited number of clients.
Consider two ways to organize a business on crayfish. The first is conventionally called “home production.” The second method involves dilution in conditions close to natural.
CREATION OF CANCERS IN UZV
Crayfish in UZV.The essence of a business idea for breeding in UZV (Installing a Closed Water Supply): the technology of breeding crayfish indoors.
Conditions for content:
The presence of a room or a separate building, where in winter the air temperature will not fall below -1 ° C (but better – not less than + 15 ° C; in the first case, the crayfish will live, in the second – they will continue to grow and gain weight).
At least three tanks of large volume of safe material (metal will not work, we take plastic or plexiglas); stones, sand and clay are poured on the bottom (the layer should be sufficient for digging holes). Polypropylene pools for UZV will cost $ 400 / piece.
Cleaning filters (a crayfish farm must be provided with clean water 24 hours a day, and with frequent manual water changes, claw-like plants do not grow and multiply, and small crustaceans may even die).
Adaptations for catching and transporting crustaceans.
Oxygenerator with oximeter 1500 $.
Feed for $ 300 is enough for six months.
Why do I need several containers?
In artificial conditions, the density of landing of individuals is too high. Naturally, large and strong crayfish will eat small ones. To prevent this from happening, after the appearance of a new offspring of adults, we separate them separately. NOT SMALL, BIG. Adult individuals adapt more quickly to new conditions. Kids can die.
What to feed? Fit pieces of vegetables, meat, some porridge. There are also special feeds for cancers.
What kind of breed? River crayfish take too long to get a presentation. The best option for a home farm – blue crayfish. We get them in a specialized fish farm.
How many individuals start growing crayfish at home? It all depends on the size of the room, the volume and number of aquariums. The ratio of males to females is 1: 3. It is better to start with a small number of individuals. Watch, gain experience – then we expand the business. For example, 80 individuals can be placed in a capacity of 300 liters.
CREATION OF CANCERS IN DACHAS
Crayfish in the pond. The essence of the idea: breeding crayfish in the pond and other natural reservoirs.
Conditions for content:
own lake, made independently or rented (it needs to be cleaned, freed from predatory fish, to prepare the bottom);
the reservoir will have to be divided into three parts with a solid net or build a separate nursery pool (in one part the crustaceans are born, in the second – they grow up, in the third – they gain presale weight);
will have to figure out how to ensure the change of water in the lake; these can be drain and supply pipes; if a river flows nearby, then you can put a powerful pump;
the density of landing of individuals is 5–7 per square meter (in practice these indicators are exceeded, but at the very beginning of their activity it is better to observe the natural requirement).
It is better to start growing with fast-growing breeds specially bred for artificial reservoirs. Then you can plant and river.
To gain a commercial weight, cancer requires an average of at least three years (under ideal living conditions). Do not believe when they say: in the spring I planted it – in the fall I caught it and sold it. This business pays off only through time. If the crayfish grew quickly, they would have stood for a penny.
BREAST OF BREED ON BREAK
Cuban blue rak.V this business success depends largely on the correct choice of the breed of cancer females, especially in the initial stages. The most interesting of them are:
Cuban Blue is an artificially bred breed of fast-growing cancer that reaches adult weight in less than a year. Cuban blue is not whimsical in the diet. Well propagated in sandy waters with hard water.
“Australian” – the most popular breed from wholesalers and restaurants. Requires chic and warm conditions for content. One individual needs 20 liters of water. But Australian cancer is very well adapted to pool growing.
“Long-fallen European” – a fast-growing and very prolific breed. Bytsro breeds in both piece and natural reservoirs.
“Marble cancer” – Large size same-sex breed. Reproduced by parthenogenesis method (female cells develop without fertilization). But for the maintenance of this breed will require a water temperature of +28 degrees.
“Red swamp cancer” is of small size, but perfectly adapted for all continents except Australia. Not whimsical to the content.
