RED SWAMP CRAWFISH - Procambarus clarkii

Find these introduced crustaceans crawling through the flooded grasslands on and around the Kern River Preserve. The native range of the red swamp crawfish (crayfish, crawdad) extends from northern Mexico to the Florida panhandle and north to southern Illinois and Ohio. This crawfish has been widely introduced outside of its range through accidental and deliberate releases. It is now found in parts of Africa, Asia and at least 15 states outside its natural range in the United States. Two similar species are raised for "Cajun" crawfish meals. The white river crawfish (P. acutus) can be told by the absence of a blue vein under the tail which is present in the red swamp crawfish. California populations of introduced crawfish have caused numerous problems including the decline of California newts and destruction of rice crops. Crawfish are used as bait in sport fishing.
