Wondering what kind of freshwater fish you might encounter while fishing in New Jersey? The list is quite extensive and filled with familiar and unfamiliar species.
Just looking at catfish, for one example, we find several species that many people would just call simply "catfish."
The most popular catfish among anglers is the Channel Catfish. This species is stocked throughout the state, from large lakes and rivers to small park ponds.

Channel Catfish
The Flathead Catfish is an unwanted invasive species. Some surpassing 20 pounds have been captured from NJ waters. Biologists have concerns for their negative impacts on recreationally important species and fish assemblages in general.
The White Catfish is NJ’s largest native catfish and is found throughout the state, but may be declining. It is commonly caught by anglers alongside of Channel Catfish. In comparison, White Catfish have a broader head, longer anal fin, and a more deeply-forked tail.
The Brown Bullhead is commonly caught by anglers and found in most ponds, lakes, most streams and rivers that do not have a high gradient. The Yellow Bullhead is similar to the Brown Bullhead, and is another catfish that is widely distributed in NJ, including the Pinelands.
A rarity is the Tadpole Madtom, which is not a tadpole in the froggy sense. Similar to the Margined Madtom, it has venom glands that can be quite painful. This species is NJ’s smallest catfish and is primarily limited to the Pinelands. It can be collected and used as bait.
