The lake trout is a slow-growing fish, typical of oligotrophic waters. It is also very late to mature. Populations are extremely susceptible to overfishing. Many native lake trout populations have been severely damaged through the combined effects of hatchery stocking (planting) and over harvest.
Lake Trout (Salvelinus namaycush) were one of the first non-native species introduced into Yellowstone. They are also the largest fish species in the park growing to an average length of 20 inches (51 cm). In 1890 42,000 fingerlings were planted in Lewis Lake and Shoshone Lake at the time, barren of fish because of Lewis Falls. [18]
Lake trout (Salvelinus namaycush), like brook trout, belong to the char genus. Lake trout inhabit many of the larger lakes in North America, and live much longer than rainbow trout, which have an average maximum lifespan of seven years. Lake trout can live many decades, and can grow to more than 30 kilograms (66 lb).

Historically, efforts in Washington have been made that seek similar results. Both brown trout and lake trout were introduced into various lakes within the Washington Cascades and monitoring took place over a 20-year span. While minimal improvements were noted with brown trout introductions, the largest success came from lake trout introductions.
The backcross is the result of an F1 splake male being crossed with a female lake trout (i.e., 75% lake trout and 25% brook trout). Although splake were first described in 1880, Ontario began experimenting with the hybrids in the 1960s in an effort to replace collapsed lake trout stocks in the Great Lakes.
