Habitat: Tench are freshwater members of the carp family that inhabit lakes with weedy or muddy bottoms.
Diet: Their diet consists of aquatic insect larvae and mollusks.
Native Range: Most of Europe and parts of western Asia
Local Concern: They have been documented in 38 states. The impacts of this species are difficult to determine because it is often lumped together with other species in the family. Tench are able to survive in low oxygen, degraded waters. It is unclear whether they cause these conditions or are simply filling a niche that native species cannot.
Potential Means of Introduction: Flooding events
