Chain pickerel (Esox niger)
The chain pickerel are a long slim bodied fish with dark chain-like patterns on its green-yellow sides and a dark marking extends downward from the eyes. An elongated mouth with many small sharp teeth.

The Smallmouth Bass is a dark to olive green coloured fish with darkened lateral bands. Dark bars radiate back from a red coloured eye and one bar radiates from the eye to the snout. The jaw does not extend past the eye. The two dorsal fins are joined together.
Distribution and abundance
Neither distribution nor abundance of fish species is uniform throughout Kejimkujik. Both are influenced by conditions of the waters such as pH and water temperature. Lakes are shallow and become quite warm during the summer months, thus limiting cool water species, such as brook trout, to the deeper holes. The remaining species are warm water tolerant.
