Abstract

The coast rainbow Salmo gairdnerii irideus Gibbons is not indigenous to Utah. Its original range is Pacific North America from Alaska to Mexico. The coast rainbow was first introduced into Utah in 1883 from McCloud River, California.

The rainbow is used more extensively for artificial propagation than any other trout in North America, both for sport fishing and as a commercial food fish. Its natural habitat is big lakes and rivers; it can adapt itself to relatively small ponds, but it does not reproduce in these ponds.

Limnological and fishery investigations on Fish Lake were initiated in 1922 and have continued irregularly until the present. These investigations have been carried on cooperatively by the Utah Fish and Game Department, the Utah Cooperative Wildlife Research Unit, the Wildlife Management Department of Utah State Agricultural College, and the U. S. Bureau of Fisheries, now part of the United States Fish and Wildlife Service. Past work has been in three major areas: limnological studies, food habits, and creel census. This paper discusses the highlights of these three phases and the life history of the coast rainbow.
