Temperate Basses (Moronidae)

The temperate basses are a small family of marine, anadromous and freshwater fishes, with most species native to North America and two occurring in marine waters of Europe and northern Africa. All North American members of the family are important gamefish, and some support significant commercial fisheries. Temperate basses have 2 unconnected or only slightly connected dorsal fins (1 spiny, 1 soft) and 1-2 small spines on the edge of the opercle. There are 3 anal spines. The pelvic fins are thoracic and have 1 spine and 5 rays. Two native species occur in Connecticut.
