Trout hatcheries of the B.C. Fish and Wildlife Branch planted, for many years, rainbow trout that were taken annually as eggs from native, wild stocks. Because of much increased demand in the last decade or two, the planting of the wild stock has been supplemented by imported domestic stocks. An experiment was designed to test for differences in survival between wild and domestic stocks after introduction into lakes in two limnological areas (Northcote and Larkin, 1956) in British Columbia.
