Hybrids
Lake trout have been known, very rarely, to hybridize in nature with the brook trout, but such hybrids, known as “splake”, are almost invariably reproductively sterile. Splake are also artificially propagated in hatcheries and then planted into lakes in an effort to provide sport fishing opportunities. These fish are easily distinguished from both lake and brook trout by the overlap of markings and coloration. A splake has bright orange fins with white tips and slightly white wormlike markings of a brook trout. Splake also have a longer lake trout jaw, teeth, dark purple back, and orientation of marks like a lake trout.
