Tiger Trout are a hybrid fish produced by crossing Brown Trout (Salmo trutta) and Brook Trout (Salmo fontinalis). This fish prefers the upper water column of rivers, lakes, or streams during spring and fall while foraging. Tiger Trout have a dark vermiculated pattern along the dorsal (back) and sides, with dark brown and olive lines contrasting against light tan, green, or yellow lines. This creates a wavy, sometimes leopard-like appearance, resembling a Brook Trout. The ventral (underside) of the fish tends to be russet-colored. Tiger trout average 25–41 cm (10–16 in) in length.
