Freshwater Fishes of Connecticut

Page 8 of 8

  • Brown Trout

    Brown trout can grow to large sizes and are generally harder to catch than brook or rainbow trout.

  • Bowfins

    This primitive family has a diverse fossil record, but only one species still exists.

  • Herrings

    There are six native species of herring that commonly enter fresh waters in Connecticut.

  • Tiger Trout

    As with hybrids between many fish species, tiger trout tend to be more aggressive and faster-growing than either parent species.

  • Brook Trout

    Brook trout prefer small, cold streams with gravel or cobble bottoms and adequate cover.

  • Temperate Basses

    All North American members of the family are important gamefish, and some support significant commercial fisheries.

  • Suckers

    Three species of suckers have been reported in Connecticut. Two are native, with the other uncertain in origin.

  • Swamp Darter

    Swamp darters are very small, camouflaged and secretive. Primarily for this reason, their distribution in Connecticut is not fully defined, nor is it clear whether their range has changed over time.

  • Golden Shiner

    Commonly sold as bait, the golden shiner is our most common lake and pond minnow species.

  • Atlantic Salmon

    Atlantic salmon were extirpated from the Connecticut River and, despite extensive restoration efforts, self-sustaining runs do not occur.
