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

Redbreast Sunfish (Lepomis auritus) - Native

16 cm redbreast sunfish.

A brightly-colored 6-inch spawning redbreast sunfish.

Identification. Body moderately deep. Mouth size moderate, reaching to below the leading edge of the eye. Opercular flap long in adults, black to its edge. Pectoral fins short and rounded (shorter than head length). Anal spines 3. Typically olive on the back fading to bluish-green on the sides and orange-red on the belly. Sides are covered with faint reddish-brown spots. One to several aqua-colored wavy lines on head behind mouth. Fins often tinged red or orange. Juveniles have faint vertical barring, which is absent in adults. Opercular flap is not long in juveniles — look for a larger mouth and slimmer body profile than those of juvenile bluegill and pumpkinseed.

This 2-inch juvenile redbreast sunfish has none of the bright coloring of an adult. A slimmer body and larger mouth distinguishes it from a young bluegill or pumpkinseed.

Size. Commonly 4 to 6 inches. State survey max. size 9.1 inches. Max. reported size 12 inches.

Distribution. Native to Atlantic coastal areas from New Brunswick to central Florida. Introduced to a few other areas. In Connecticut, the redbreast sunfish has a patchy distribution across all major watersheds. They are typically common in rivers and large streams and uncommon to rare in lakes.

Habits. Prefer clear water and rocky areas of larger streams and lakes. Not typically associated with vegetation. They are more tolerant of current than other sunfishes and are often the dominant sunfish species in larger rivers. Can be taken by angling with small lures or bait (especially worms). Redbreast sunfish are relatively easy to keep in home aquariums. They will accept pellets, but require some fresh food. They are not as tolerant of warm or poor-quality water as pumpkinseed or bluegill.

Comments. In Connecticut, the redbreast sunfish typically outnumbers other sunfish species only in river environments. They readily hybridize with other sunfish species.
