Connecticut’s 3,000+ miles of rivers, 2,100 lakes/ponds, and 618 square miles of Long Island Sound coastline make it an angler’s paradise. But before casting for trophy striped bass in the Thames River or brook trout in the Appalachian Highlands, you’ll need a valid fishing license. This 2,800-word guide incorporates 2025 fee updates, new regulation changes, and verified links to official CT DEEP resources to ensure full compliance with state laws.
