Abstract

Invasive crayfish have become well-established in Flanders. Most of the species are widespread and eradication seems improbable. Yet, managers are looking for control measures to mitigate the density dependent impacts of invasive crayfish. This preliminary experiment explores predation of two benthic predatory fish burbot (Lota lota) and European catfish (Silurus glanis) on the marbled crayfish (Procambarus virginalis) and evaluates their potential for use as a future control measure.
