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

Rudd (Scardinius erythrophthalmus) - Introduced/Close Neighbor

Male rudd.

Rudd have not yet been found in Connecticut, but established populations exist in neighboring states. Noel M. Burkhead USGS photo.

Identification. Similar to golden shiner. Deep-bodied. No conspicuous markings. Downward curved lateral line. Dorsal fin rays 9-11. Anal rays 10-12. Keel between pelvic fins and anus scaled. Adults silvery, gold or copper-colored with orange to reddish fins.

Size. Commonly 10 to 12 inches. Max. reported size 20 inches.

Distribution. Widely distributed from Europe to middle Asia. Introduced to areas of the Central and Northeastern United States. Rudd have not yet been found in Connecticut waters, but self-sustaining populations have been discovered in both New York and Massachusetts. At least one instance of rudd occurring in a Connecticut bait store (mixed in with golden shiners) has been reliably reported.

Habits. Prefer slow-moving waters of rivers and lakes with at least moderate amounts of vegetation. Pollution tolerant. Can be caught by angling with bait.

Comments. Most rudd found in this country were probably introduced through bait bucket releases. Rudd are superficially similar to golden shiners and can be mistakenly imported with them by bait dealers. For this reason, rudd populations may soon become established in Connecticut. There is concern that they may negatively impact other fish populations.
