World of Crayfish™ database and website

World of Crayfish™ is an ambitious new website that shows the geographic distribution of crayfish species in near real-time.


Of course, I checked for whether there was a Marmorkrebs map. There is! Click to enlarge!

It’s clearly out of date in some ways. I expected to see records from Madagascar, as several localities published in peer-reviewed journals have been available for some time. On the other hand, there seem to be new records that I have not found yet, like in southern France.

Nevertheless, this seems like a much more organized effort that might eventually supplant my own map of Marmorkrebs introductions.

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.
