Species that are considered high risk have a well-documented history of invasiveness in at least one location globally, and a high or medium climate match to the contiguous United States.
Tinca tinca is a freshwater and brackish water cyprinid fish native to Eurasia. This species has established in many countries outside of its native range, including the U.S. This species has a high climate match with the contiguous U.S. overall. Bait bucket introductions, flooding, and natural range expansion are all possible vectors for this species to be introduced to new areas. Impacts include direct effects on native carp abundance and molluscan biomass, plus indirect effects on macrophyte growth and water quality. Two OIE-reportable diseases have been detected in T. tinca. However, not all locations where T. tinca has been introduced have reported impacts of introduction, and numerous introductions have failed to progress to population establishment. Overall risk assessment category is high.
