Invasive Blue Catfish

Caption

"Blue cats" were introduced to tidal freshwater stretches of the James, York, and Rappahannock rivers during the 1970s and 1980s to enhance recreational fisheries. They feed on vegetation, mollusks, and fishes, often out-competing native species such as white catfish. Their continued spread thus concerns fisheries managers.
