Splake
The splake or slake (Salvelinus namaeycush X Salvelinus fontinalis) is a fish. It is the hybrid of a male brook trout (Salvelinus fontinalis) and a female lake trout (Salvelinus namaycush).  The name is a combination of speckled trout (another name for brook trout) and lake trout. The name may have been used as early as the 1880s. Hybrids of the male lake trout with the female brook trout (the so-called "brookinaw") have also been produced, but are not as successful.
