Znaczenie raków w Polsce i konieczność ich ochrony

In the past, the noble crayfish (Astacus astacus) was an important export commodity in Poland. As a result of pollution and crayfish plague, the situation in Poland has changed. Despite the fact that the species is protected by law, Astacus astacus is currently present in only a few dozen habitats. In order to improve their prospects it is important to continue work on breeding and restitution of the population.
