Tiger trout (brook and Brown hybrids) are sterile so there would be no diluting the gene pool so to speak. Wild tigers are extremely rare too because while both Brown's and Brooks are fall spawners they don't spawn at exactly the same time and a fertilized hybrid egg has a pretty low survival rate on top of that. The bigger concern is that Brown trout have an easier time getting bigger than brook trout and could out compete them if the stream is large enough. But I also agree with the keep all other salmonids out of SNP at all costs approach. With climate change set to decimate trout fisheries in the coming decades, keeping brook trout strongholds in tact is important.

The northern Appalachian strain of brook trout should be preserved and the fact that brown and brook trout can hybridize is my reasoning, especially in national parks.Outside of the park is a different story, but as we know, trout migrate when they can to waterways more suited to their needs, as seen when fishing some of the rivers at the lowest end of the park boundaries and finding species other than chubs and brook trout.RFrom: Tidal Potomac Fly Rodders <tidal-potomac-fly-rodders@googlegroups.com > on behalf of Dalton Terrell <daltonbterrell@gmail.com>

Subject: Re: {Tidal Potomac Fly Rodders} Re: Anybody fished Pass Run in SNP for bows?We should probably stock a few a few streams in SNP with brown trout, and to keep it interesting, we should also place some eastern brown snakes and brown bears around these streams. While we're at it, we might as well stock some brown dinosaurs, no harm in turning Shenandoah National Park into Jurassic Park.--
With that, my TurbineBlade impersonation is over...
Alternatively, we could preserve one of the few areas left in the state with mostly native species as it is.
