I would love to "Go Fishing" for a tiger trout. They are a hybrid of a female brown trout and a male brook trout. They are distinctive, the dark modeled pattern of a brook trout’s back extending down their sides to their belly. They do breed wild now, (like the muskellunge/northern pike hybrid - the tiger muskie) but, since they are a hybrid trout you could place them at any location where you already have trout species.
