Our Danish partners have been dealing with the reintroduction of the fire-bellied toad for many years - they adapt the areas where it used to occur to its needs, e.g. by recreating water reservoirs. From areas where toad-bellied populations are currently strong and not directly endangered, they obtain eggs, which they place in specially prepared breeding stations. It is in them that tadpoles hatch, metamorphosis takes place and young, fully developed individuals are formed - they end up in the target ecosystems.
The Danes use two methods of farming the toad (and other amphibians). The simplest and cheapest, although the least effective, is box farming. The whole metamorphosis takes place here in specially prepared boxes placed in a water reservoir. At the same time, it is difficult to protect tadpoles from all predators. A better, more effective, but also much more expensive method is the breeding of amphibians in completely artificial conditions - the eggs go to plastic boxes, and hatching tadpoles - to small pools. Of course, during the entire metamorphosis process, constant care and feeding of tadpoles is necessary.
