Splake behavioural sterility of splake, all such fisheries are entirely dependent on artificial propagation. Splake The splake or slake ("Salvelinus namaycush x Salvelinus fontinalis") is a hybrid of two fish species resulting from the crossing of a male brook trout ("Salvelinus fontinalis") and a female lake trout ("Salvelinus namaycush"). The name itself is a portmanteau of speckled trout (another name for brook trout) and lake trout, and may have been used to describe such hybrids 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
Splake to the point where they no longer produce brook trout are stocked with splake. The splake grow more quickly than do wild-strain brook trout and become piscivorous at a younger age and, hence, are more tolerant of competitors than are brook trout. In the second case, relatively small lake trout lakes that experienced poor recruitment due to insufficient deep-water juvenile lake trout habitat will support fairly good splake fisheries, since splake are less dependent on extreme deep water than are the lake trout and they grow more quickly, providing a better return to anglers. In both cases, due to the
