  • Codfishes

    Codfishes are characterized by having a single barbel on the middle of the chin.

  • Atlantic Menhaden

  • Sea Lamprey

    The state's only parasitic fish to enter freshwater, the sea lamprey gets a bad reputation. Learn more about this fascinating fish.

  • Northern Pike

    The northern pike is Connecticut’s largest strictly freshwater gamefish.

  • Green Sunfish

    Introductions of green sunfish have been implicated with adverse impacts on other fish species.

  • Brown Bullhead

    The brown bullhead is Connecticut’s most widely distributed and only native catfish species. They are good to eat, but are typically underutilized by anglers.

  • Yellow Bullhead

    They were first observed in Connecticut in the early 1980s at a few disjunct sites in the lower Housatonic and upper Quinebaug River drainages. Populations are expanding in both of these drainages, and individuals have recently been discovered in the Connecticut River drainage as well.

  • Sculpins

    Sculpins have a flattened head, large frog-like mouth and eyes, a scaleless body, and large fan-shaped pectoral fins.

  • Tessellated Darter

    Sometimes bury themselves in the sand with only eyes and tail tips exposed. Can be easily captured with small-mesh dip net or seine.

  • Banded Sunfish

    The banded sunfish is listed as a Connecticut State Threatened Species. Their small size makes them vulnerable to predation by bass and other large gamefish, so they thrive only in protected, backwater areas.

  • American Soles

    A small family limited to marine waters of the Western Hemisphere.

  • Slimy Sculpin

    Sculpins are sensitive to environmental degradation, requiring good-quality, coldwater streams to survive.

  • Sturgeons
