Invasive Red Swamp Crawfish on the Move in Laurel

Type: Freshwater
Region: Central
Location: Patuxent River

Linda DeMarco of Laurel, Maryland wrote in last week regarding a crawfish she came upon while walking to work near the Patuxent River. Linda sent in the below photos and as if we could identify the species.

DNR's response:
The crayfish you found on the sidewalk in Laurel is the Red Swamp Crawfish (Procambarus clarkii). This is a non-native species that has been introduced to Maryland. It is the typical “Louisiana” crayfish and is the species that is typically sold for food in the south. It is now common on Maryland’s Eastern Shore and in several Potomac and Patuxent River tributaries. Red Swamps were first brought to Maryland for aquaculture, but have also been imported and sold as pets and as bait. Jay Kilan, DNR Biologist

Reminder - there is a crayfish ban on particular waterways, please read our news story http://dnr.maryland.gov/fisheries/news/story.asp?story_id=8.
