The Arkansas Game and Fish Commission says a piranha has been caught at Lake Bentonville.
The commission brought in a state biologist to confirm the species last week after a Bella Vista woman posted pictures of the fish on Facebook.
Assistant Chief of Communications Keith Stephens tells KATV-TV that piranhas are caught occasionally in Arkansas. He says people typically release them from aquariums.
Stephens says piranhas can't survive winter water temperatures.
The commission says it's illegal to introduce non-native species into the water and that violators face a $250 fine.
