Ecological Risk Screening Summary - Headwater Catfish (Ictalurus lupus) - Uncertain Risk

Species that are considered uncertain risk need a more in-depth assessment beyond the Risk Summary to better define the species’ risk to U.S. environments.

Ictalurus lupus is a catfish native to New Mexico, Texas, and northern Mexico. Although intentional introductions of I. lupus have been documented, it is unclear if these populations became established. I. lupus has a high climate match with the United States, with the areas of highest match located in New Mexico and Texas, which is the native U.S. range of this species. Overall risk assessment category is uncertain.
