Crayfish are very specific. Like any seafood, they are not stored for long. Of course, it is best to boil them immediately after the purchase, but what if it is not possible? Fortunately, there are several ways to keep the crayfish alive for several days.

For the full functioning of all life support organs, the cancer must remain in the water, preferably in the very one from which it was pulled. As a rule, cages are used to store crayfish. The charge material is not important. It can be wood, plastic, but most often metal grids are used for these purposes. The cage should be placed in a container with river water and covered. If this is not possible, then you can put the cage in the bathroom with plain water. It needs to be changed every day, since crayfish need oxygen, which is obtained from water. It should be borne in mind that crayfish must be fed, otherwise from hunger they will begin to eat each other. They prefer fish from food, but such food can provoke fights, which in crayfish usually end in trauma in the form of a lost claw. It is better to give preference to plant foods: raw potatoes, pea pods, various herbs. This storage method will extend the life of cancers no more than 3-5 days, however, all individually.

Crayfish can be stored outside the aquatic environment, but since it is difficult to breathe without water, the shelf life in air is only 1-2 days. Crayfish should be kept in a cool and humid place. The room must be ventilated as often as possible. Maintain life will help regular spraying from a spray bottle. With an absolute absence of water, the cancer suffers from pain due to the release of lactic acid.

Some housewives store live crayfish in the refrigerator. To do this, they are washed under running water and placed in a clean plastic bag on the bottom shelf of the refrigerator or in the compartment for storing fruits and vegetables. This is a freshness zone where the temperature is around 0ºС. In such conditions, crayfish can live no more than 4 days.

It is necessary to monitor the condition of the cancers and if a dead animal is found, it must be immediately removed from the total mass. Firstly, carrion cancers are scavengers and will immediately begin to eat dead cancer for food. And besides, a rather strong smell emanates from the decaying carcass. Secondly, he may accidentally get into the pan with live crayfish, and then the whole batch will need to be thrown out, as toxins that have caused severe poisoning have already entered the water. And the taste of the crayfish will be completely ruined. Dead cancer can be identified by a complete lack of movement and an absolutely straight neck, which is always slightly twisted in living cancers.
