Emergency Burn Ban In Effect 10/26/24 - An emergency burn ban is now in effect for all Connecticut State Parks, Forests, and Wildlife Management areas, prohibiting the use of all outdoor grills, firepits, and campfires, and the kindling and use of flame outdoors. DEEP and local agencies are working to contain several active fires across the state. Please avoid all affected State Parks and Forests, as well as the blue-blazed Mattabesett Trail. The Enduro Trail in Voluntown and portions of North Stonington within the Pachaug State Forest are closed at this time. Please note that today's forest fire danger report remains at an 'extreme' level. More information about the current fire danger, burn ban and recommended safety measures can be found here

Channel Catfish (Ictalurus punctatus) - Introduced

47 cm channel catfish.

A 19-inch adult channel catfish from the Connecticut River.

Identification. Similar to white catfish. Tail fin deeply forked. Anal fin longer than white catfish (25-29 rays). Head and mouth generally smaller and narrower than white catfish. Dark chin barbels. Several to many black spots on sides of younger fish. Long barbels at corners of mouth (more than three times as long as barbels near nostrils). Typically dark gray, sometimes brownish on the back, fading to light gray on the sides to almost white on the belly. Mature males and large fish can be very dark.

Juvenile channel catfish.

Juvenile channel catfish typically have several to many dark spots on their sides.

Size. Commonly 12 to 20 inches. State survey max. size 28.7 inches. Conn. State Record 29.4 pounds, 37.5 inches. Max. reported size 4.3 feet. World Record 58 pounds, 47.5 inches.

19 lb channel catfish.

Very large channel catfish, such as this 19-pounder taken from Mohegan Park Pond, Norwich, typically have large heads and wide girths.

Distribution. Native range is throughout the eastern two-thirds of the United States and southern Canada, excluding most of the Atlantic coastal states from Maine to South Carolina. Widely introduced elsewhere. In Connecticut, the largest population is found throughout the Connecticut River, where they are common to abundant. The Connecticut River population has expanded considerably during the last 20 years, probably displacing the once more common white catfish and brown bullhead. A small, self-sustaining population may be present in the lower Housatonic River. Elsewhere in the state, individuals are occasionally found in lakes and ponds (most having been illegally transplanted by anglers).

Habits. Prefer rivers and larger streams with fairly clean water. Can be found in lakes and ponds, but typically will not successfully reproduce in smaller lakes. Usually associated with non-vegetated areas. Most active at night, but will also feed during the daytime. Channel catfish can readily be taken with bait (for example, nightcrawlers or minnows) fished near the bottom. Because they are more active predators than other Connecticut catfishes, they can also occasionally be taken on artificial lures.

State record albino channel catfish.

Comments. The channel catfish is the state’s largest catfish species. The largest individuals are invariably taken from lakes and ponds, where they grow quickly due to little competition for food. Old fish can be difficult to distinguish from white catfish because many features become less distinct (head enlarges and fins become worn). The channel catfish is a very popular sport and food fish throughout the country. They are commercially farmed and are usually the “catfish” found in supermarket seafood sections. Albino channel catfish are commonly sold in aquarium stores. The State Record was recently (2004) caught in Mashapaug Lake (Union), where channel catfish had not previously been documented. Because of this and the fact that the fish was an albino, it probably originated from an illegal aquarium release. Blue triangles on the state range map represent sites for which anglers received trophy-fish awards for channel catfish.
