The brook trout (Salvelinus fontinalis), sometimes called the eastern brook trout, is a species of fish in the salmon family of order Salmoniformes. The brook trout is the state fish for eight states: Michigan, New Hampshire, New Jersey, New York, Pennsylvania, Vermont, Virginia and West Virginia. The brook trout inhabits small streams, creeks, lakes, and spring ponds. This species is green to brown in basic colour, with a distinctive marbled pattern (called vermiculations) of lighter shades across the flanks and back and extending at least to the dorsal fin, and often to the tail. A distinctive sprinkling of red dots, surrounded by blue haloes, occur along the flanks. The belly and lower fins are reddish in color, the latter with white leading edges. Often, the belly, particularly of the males, becomes very red or orange when the fish are spawning. The species reaches a maximum recorded length of 86 cm (33 in) and a maximum recorded weight of 6.6 kg (14.5 lb).
