Abstract
The crayfish plague is believed to have been introduced to Europe from North America in 1860 and is still spreading between and within countries. Since 1907, when the plague started to spread in Sweden, most of the native crayfish populations have been infested and the fishing is mostly still ruined, in spite of large-scale stocking with healthy crayfish. Test fishing shows that, in many cases, isolated crayfish may survive the plague without being resistant. Scattered individuals or small local populations thus form the remains of the former productive populations. Different explanations as to why reclamation trials have proved unsuccessful have been discussed. The most plausible one seems to be the survival of the plague and the crayfish together in a very unbalanced relationship where the density of the host population is very low. Reclamation trials of populations of native European crayfish species seem to be successful only if the host animal has been completely eradicated.
