Invasive American Crayfish To Become Berlin Delicacy

BERLIN, GERMANY - MAY 08: Fisherman Klaus Hidde (R) and nature and landscape guide Malte Frerichs (R) catching red swamp crayfish (procambarus clarkii, also known as Louisiana crayfish) during a media opportunity in waters in Tiergarten park on May 8, 2018 in Berlin, Germany. The red swamp crayfish is native to northern Mexico and the southern United States and is believed to have been introduced to lakes and creeks in and around Berlin by people who had them as pets. The crayfish have multiplied dramatically, so much so that Berlin authorities, fearing negative effects of an invasive species, have given fisherman Klaus Hidde a license to catch as many of them as he can. Authorities are allowing him to sell the creatures, which are red and on average about 15cm long, to local restaurants. (Photo by Carsten Koall/Getty Images)
