Lake Trout or Mackinaw: 

 Lake trout (Salvelinus namaycush) is a freshwater char living mainly in lakes in northern North America. Other names for it include mackinaw, lake char (or charr), touladi, togue, and grey trout. In Lake Superior, it can also be variously known as siscowet, paperbelly and lean. The lake trout is prized both as a game fish and as a food fish.

Kokanee 

Kokanee are the land-locked form of sockeye salmon. Because they never migrate out to the ocean to feed, kokanee are often much smaller than sockeye. However, other than their size, kokanee have very similar identifying characteristics as sockeye. Most kokanee live in a lake for most of their lives, so you can usually see them spawning near the edge of a lake or in a small tributary that feeds into a lake. 

Rainbow Trout

The rainbow trout is a member of the salmon family of fishes and has the following characteristics:

  • an elongate, laterally compressed body;
  • a rounded snout, which becomes extended and the lower jaw turns up in breeding males;
  • the back, upper sides and the top of the head are steel blue, blue-green, yellow-green to almost brown;
  • the sides are silvery, white or pale yellow-green to grey, and marked with a pink blush to red band and many small black spots;
  • the underside is silvery, white or grey to yellowish;
  • the dorsal and caudal fins have radiating rows of black spots, while the remaining fins are buff with few spots; and stream dwelling and spawning brown trout display darker, more intense colours, whereas lake residents are lighter, brighter and more silvery.

The species has been introduced for food or sport to at least 45 countries, and every continent except Antarctica. In some locations, such as Southern Europe,Australia and South America, they have negatively impacted upland native fish species, either by eating them, outcompeting them, transmitting contagious diseases, (such as whirling disease transmitted by Tubifex) or hybridization with closely related species and subspecies that are native to western North America.

Mountain White Fish

The mountain whitefish (Prosopium williamsoni) is one of the most widely distributed salmonid fish of western North America. It is found from the Mackenzie Riverdrainage in Northwest Territory, Canada south through western Canada and the northwestern USA in the Pacific, Hudson Bay and upper Missouri River basins to theTruckee River drainage in Nevada and Sevier River drainage in Utah.
The body shape is superficially similar to the cyprinids, although it is distinguished by having the adipose fin of salmonids. The body is slender and nearly cylindrical in cross section, generally silver with a dusky olive green shade dorsally. The short head has a small mouth underneath the snout. The short dorsal fin has 12-13 rays, with 11-13 for the anal fin, 10-12 for the pelvic fins, and 14-18 for the pectoral fins. The tail fin is forked. Size has been recorded at up to 70 centimetres (28 in) in length and a weight of 2.9 kilograms (6.4 lb).
It is a fish of mountain streams and lakes, favoring clear cold water and large deep pools of at least a meter depth; the Lake Tahoe population lives just above the bottom in deeper water. Mountain whitefish are bottom feeders, stirring up the substrate with pectoral and tail fins to expose insect larvae and other invertebrates, including snails, crayfish, and amphipods. Their main feeding time is in the evening, but they will also take drifting prey during the day. The mountain whitefish frequently feeds in the lower strata of streams, but populations may rise to the surface to prey on hatching insects, including mayflies.
