SCIENTIFIC NAME: Esox americanus
The cheeks and gill covers on the redfin pickerel are fully scaled, while the top of the head has few if any scales. A darkened vertical bar beneath the eye slants slightly backward. In cross section, the body is oval or cigar-shaped. The back is dark green to brown. Color patterns on the sides are variable, from a green-and-white reticulate pattern resembling that of a brick wall to green, forward-slanting vertical bars. Along the lower sides, fingerlike green projections extend downward and forward onto a cream or yellow venter.

Crossman (1966) distinguishes two subspecies. The redfin pickerel, Esox americanus americanus, is an Atlantic Coast form, its range extending from New York south to eastern drainages in Georgia. The grass pickerel, E. a. vermiculatus, occurs throughout the Mississippi basin, including the Tennessee River in northern Alabama. Redfin pickerel inhabiting Gulf Coast drainages from the Mobile basin east into Florida and southwestern Georgia are intergrades between the two subspecies. Redfin pickerel are more widespread and abundant below the Fall Line. Few collections are available above the Fall Line or in the Tennessee River drainage.
HABITAT AND BIOLOGY:
Redfin pickerel usually occur in clear streams having slow to moderate currents and abundant aquatic vegetation or undercut banks. We have also collected them in swamps and isolated overflow pools of rivers. The young occur in schools, but adults are solitary, aggressive predators. An individual will lie motionless along the edge of aquatic vegetation or an undercut bank for long periods. When unsuspecting prey appears, the fish darts out, grasps the prey, and swallows it head first. Large insect larvae, crayfishes, and fishes are staples of the adult diet. Redfin pickerel live to six years; grass pickerel reach seven years (Carlander, 1969).
Anglers are not likely to encounter this species, since it usually inhabits small streams.
Gmelin described the redfin pickerel in 1788.
Esox means pike.
