The harvested snails can be stored in the refrigerator for up to 12 months. But it should be understood that the sooner you can sell the crop, the better.
The First Reason
Their storage demands significant electricity costs (for refrigerators to work);
The Second Reason
In 6 months the snails dry up by 20-30% (and there is actually less ready for sale product). Therefore, to reduce the cost of storing the snails, they should be sold as soon as possible after collection.
