Ecological Risk Screening Summary - Blue Catfish (Ictalurus furcatus) - High Risk

Document - application/pdf

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.

Blue Catfish (Ictalurus furcatus) is a freshwater and brackish water catfish native to portions of the Mississippi River basin, Texas, and Mexico. Stocking, aquaculture, and migration have all contributed to the spread of this species throughout much of the southern half of the United States. Impacts such as hybridization with native species, reduction of native fish abundance, and alteration of local habitats have been reported for this species leading to a high history of invasiveness. This species has a high climate match within the United States, with all states in the contiguous United States having individually high climate matches. The overall risk for this species is high.

The Fish and Aquatic Conservation program leads aquatic conservation efforts for the U.S. Fish and Wildlife Service. We are committed to tackling the nation’s highest priority aquatic conservation and recreational challenges to conserve, restore, and enhance fisheries for future generations.
Aquatic invasive species cause tremendous harm to our environment, our economy, and our health. They can drive out and eat native plants and wildlife, spread diseases, and damage infrastructure. We work to protect our waterways and the communities that depend on them from the threat of invasive...
