The species index

Blue-green to olive back, silver sides and belly, with black spots on the body and on the dorsal, adipose, and caudal fins.

Dark green to olive back with silvery sides and irregular dark spots covering the entire body.

Bold, dark vermiculations (tiger-stripe markings) covering a brownish-gray body, more pronounced than on either parent species.

Bright silvery body with no definitive spotting pattern, unlike rainbow, cutthroat, or brown trout.

Hybrid cross between a female striped bass and a male white bass, blending traits of both parents.

Two separate dorsal fins, with a dark spot at the base of the spiny first dorsal fin.

Deeply forked tail, unlike the rounded or square tails of bullhead catfish.

Dark olive-green back with pale, worm-like markings (vermiculations), unlike the spotted pattern of rainbow or brown trout.

Golden-brown to olive body with dark spots ringed by pale halos, the key trait separating them from other stocked trout.

Hybrid cross between lake trout and brook trout; unlike most hatchery hybrids, splake are fertile and can reproduce.

Sterile hybrid between northern pike and muskellunge, with dark spots (as a juvenile) or vertical stripes and bars over a light background.

Char with a gray-brown background overlaid by light spots that vary in intensity with age and habitat.

Same species as rainbow trout, but steelhead migrate to sea and return to spawn, while rainbow trout stay in fresh water for life.

Deep, laterally compressed body with large, rounded dorsal and anal fins.

Silvery to light purple sides with a bluish-white belly and a relatively slender body.

Dark blue-black spot on the back edge of the gill cover, the trait that gives the species its name.

Greenish-black body with a bold dark horizontal band along the midline, fading toward a lighter belly.

Fertile hybrid between rainbow trout and cutthroat trout, unlike the sterile tiger trout or splake.

Golden-yellow body with 6 to 8 broad, dark vertical bands running from back to belly.

Gray, charcoal, or green back with silvery sides and a white belly.

Long, bluntly pointed snout; jaw stops near the middle of the eye, unlike the past-the-eye jaw of largemouth bass.
