The brook trout produces [[Hybrid (biology)|hybrid]]s both with its [[congener (biology)|congener]]s the [[lake trout]] (S.''&nbsp;namaycush'') and the [[Arctic char]] (''S.&nbsp;alpinus''), and intergeneric hybrids with the [[brown trout]] (''Salmo trutta'').<ref>{{cite book |last1=Dunham |first1=Rex |title=Aquaculture and Fisheries Biotechnology: Genetic Approaches |date=2004 |publisher=CABI Publishing |isbn=0851999530 |location=Wallingford |page=42}}<!--|access-date=20 November 2014--></ref>

The [[splake]] is an intrageneric hybrid between the brook trout and [[lake trout]] (''S.&nbsp;namaycush''). Although uncommon in nature, they are artificially propagated in substantial numbers for stocking into brook trout or lake trout habitats.<ref>{{cite web |title=Splake |url=http://www.maine.gov/ifw/fishing/species/identification/splake.htm |access-date=2013-01-06 |publisher=Maine Department of Inland Fisheries|archive-url=https://archive.today/20140107053231/http://www.maine.gov/ifw/fishing/species/identification/splake.htm|archive-date=January 7, 2014}}</ref> Although they are [[Fertility|fertile]], back-crossing in nature is behaviorally problematic and very little natural reproduction occurs. [[Splake]] grow more quickly than brook trout, become [[Piscivore|piscivorous]] sooner, and are more tolerant of competitors than brook trout.<ref>{{cite web |title=NAS - Nonindigenous Aquatic Species ''Salvelinus fontinalis x namaycush'' |url=https://nas.er.usgs.gov/queries/FactSheet.aspx?SpeciesID=940 |access-date=2014-01-06 |publisher=U.S. Geological Survey}}</ref>

The [[tiger trout]] is an intergeneric hybrid between the brook trout and the brown trout. Tiger trout rarely occur naturally but are sometimes artificially [[Hatchery#Fish hatcheries|propagated]]. Such crosses are almost always reproductively [[infertility|sterile]]. They are popular with many fish-stocking programs because they can grow quickly, and may help keep coarse fish (wild non "sport" fish) populations in check due to their highly piscivorous (fish-eating) nature.<ref>{{cite web |title=Tiger trout |url=http://www.utahfishinginfo.com/utahfish/tigertrout.php |archive-url=https://web.archive.org/web/20060528023009/http://www.utahfishinginfo.com/utahfish/tigertrout.php |url-status=usurped |archive-date=May 28, 2006 |access-date=2014-05-28 |publisher=UtahFishingInfo.com - Utah Fishing Information}}</ref>
