The brook trout, Salvelinus fontinalis, is a species of fish in the salmon family of order Salmoniformes. 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 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 33 in and a maximum recorded weight of 14.5 lb.
The brown trout, Salmo trutta, is an originally European species of salmonid fish. Brown trout can live to ages of 20 years. Cover or structure is important to trout, and they are more likely to be found near submerged rocks & logs, undercut banks, and overhanging vegetation. While in fresh water, their diets will frequently include invertebrates from the streambed, other fish, frogs, mice, birds, and insects flying near the water's surface. The high dietary reliance upon insect larvae, pupae, nymphs and adults is what allows trout to be a favoured target for fly fishing. On Sept. 11, 2009, a 41.45-lb brown trout was caught by Tom Healy in the Manistee River system in Michigan, setting a world record.
The rainbow trout, Oncorhynchus mykiss, is a species of salmonid native to tributaries of the Pacific Ocean in Asia and North America. Many anglers consider the Rainbow trout the hardest fighting trout species, as this fish is known for leaping when hooked and putting up a powerful fight. Rainbow trout, also called redband trout, are gorgeous fish, with coloring and patterns that vary widely depending on habitat, age, and spawning condition. They are torpedo-shaped and generally blue-green or yellow-green in color with a pink streak along their sides, white underbelly, and small black spots on their back and fins. They average about 20 to 30 inches long and around 8 pounds, but can grow as long as 4 feet and weigh up to 53 pounds.
