Blue Catfish

As their name suggests, the blue catfish (Ictalurus furcatus) is light or dark blue with a white underside.

They have a forked tail with a straight anal fin consisting of around 32-36 rays. These are relatively large fishes primarily found in the river’s main channel and tributaries.

These catfish natively dwell in Missouri, Mississippi, and Ohio rivers and serve as an excellent food source.

They are also powerful due to their heavy body structure and can put up a great fight with their opponent. Accordingly, they are a popular game fish for anglers.

Flathead Catfish

The flathead catfish (Pylodictis olivares) are mottled brown, black, and pale yellow, with beige bellies. Unlike blue catfish, flatheads do not consist of a forked tail but have a short, round anal fin with less than 30 rays. 

As their name suggests, the flathead catfish have flattened heads, with their jaws often protruding outwards. They mostly have smooth bodies with no fins and cat-like whiskers near the mouth.

They live on hunting plants, insects, mussels, fish, and crustaceans. Channel fish are the most active at night when they come out to hunt in the dark because of their extreme sense of smell.

They are mostly found in freshwater environments like rivers, lakes, reservoirs, and large streams.

Their shades range from grey to white, with a spotless body. Due to being toothless, the Mekong giant catfish primarily feed on algae, zooplankton, and larvae.

These catfish are among the largest catfishes dwelling in freshwater environments, with their size growing up to 661 lbs and about 10 feet long. The Mekong Giant Catfish is native to the Mekong River in East and Southeast Asia.
