Common name: Redfin Pickerel
available through www.itis.gov
Identification: According to Page and Burr 1991, the Redfin pickerel has a fully scaled cheek and opercle. There is a black suborbital bar slanted toward the posterior. The dorsal surface is dark olive-brown and the ventral side ranges from white to amber colored. There are typically 15-36 dark bars on the lateral side of the adults. There are between 11-13 branchiostegal rays; about 4 submandibular pores; and 92-118 lateral scales (Page and Burr 1991).
Size: Up to 15 inches (28 cm)
Native Range: E. a. americanus is species is found along the Atlantic slope from Massachusetts to Lake Okeechobee in Florida; in the Gulf drainages west to the Pascagoula River in Mississippi (Crossman 1978; Page and Burr 2011).
Individuals in the south and southwestern part of the range are intergrades with E. a. vermiculatus (Crossman 1978; Lee et al. 1981).

† Populations may not be currently present.
Ecology: This species can be found in lakes, swamps, backwaters, and sluggish pools of streams. Typically found in clear water among vegetation (Page and Burr 1991).
Means of Introduction: Typically stocked for sport. Its presence in the Lake Champlain drainage is the result of a canal connection to the native range in the Hudson River (Crossman 1978).
Status: Established in the Lake Champlain/Richlieu drainage (Crossman 1978; Page and Burr 2011).
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
