Ictiobus cyprinellus
The Bigmouth Buffalo is a large and rugged fish native to North America. They inhabit larger rivers, lakes, and reservoirs, where they roam the depths in search of food. With their wide, thick heads and large mouths, they are often confused with the more commonly known Buffalo fish, but their unique size and shape make them stand out. Unlike most freshwater fish, Bigmouth Buffalo are adept at surviving in areas with lower oxygen levels, as they can gulp air at the surface to compensate.
These fish are often found in schools and are mainly herbivorous, feeding on algae, plant matter, and plankton. While not as aggressive as some other fish species, their powerful bodies and size make them an impressive catch. Because of their strength, many anglers enjoy targeting Bigmouth Buffalo for the challenge, even though they can be difficult to hook due to their lower activity levels.
