England vs US crayfish bad news good news

The challenge

The White clawed crayfish, Austropotamobius pallipes, is being bullied out of its home turf by none other than an American red signal crayfish. sort of like the American Revolution in reverse. In the 1970s the American red signal crayfish (Pacifastacus leniusculus) was introduced into England.

Two groups are working to [protect not only the native crayfish but invertebrates and native vegetation of the rivers around Brecks, in eastern England, the Lark Angling and Preservation Society (LAPS) and the Brecks Countryside Project. Seems that the American has forgotten its manners and overstayed its welcome, the omnivorous signal crayfish consumes everything in sight.


The good news
Now how to handle the huge numbers of crayfish caught (over 600,000 in 2005) in the reclaim the rivers program?

By creating a demand for the crayfish as a low in fat and high in protein it created a new industry and new jobs while protecting the whiteclaw and other native animals and plants and the ecosystem of the river environment.
