What I find ironic is, the best native brookie stream I've fished isn't even on the Class A list.
PA fish and Boats classification system makes no sense from a fisheries science standpoint. They call a short segment of stream “class A” because of a threshold density of wild native brook found in kg/hectar but this does not factor in conservation genetics and how important that stream is connectivity wise to the larger meta population. This outdated ineffective classification system also ignores fine scale and long distance movement of fish, they move in and out of these short class A sections obviously.
Shannon whites telemetry/genetics study in loyalsock creek shows they use the whole watershed and we need to manage the whole watershed for them if we are serious about having healthy populations, this much is scientifically obvious at this point. Pa fish and boat continues to fail native brook trout and is so behind other state fish agencies it’s baffling. NJ, MD, WV, VA do SO MUCH more with so much less brook trout water in terms of actually managing for them and creating large healthy populations that people rate as good fisheries . Our stream classification system is designed to accommodate irresponsible stocking by drawing arbitrary boundaries in trout streams that don’t have any ecological significance to promote the fallacy that we are some how managing for wild native brook trout. There is so much potential for native brook trout conservation if you read fisheries journal articles. But Pa fish and Boat would have you all believe that the water in PA just isn’t cold enough or clean enough anywhere in the state to have larger streams with healthy native brook trout populations like VA,MD and WV do that are south of us. There are exciting new solutions to improve the health of our native brook trout populations such as
1. Genetic rescue for in inbred populations(worked with great success in North Carolina)
2.XYY genetic supermale invasive trout species
3. Selective manual removal of invasive trout combined with super males.
4.bolstering genetic adaptive potential of brook trout by prevention of introgression and outbreeding depressing/inbreeding depression.
5. The ability of brook trout to survive higher stream temps if brown trout are not present due to enhanced use of fine scale thermal Refuge.
6. Ground water manipulation/spring pond dam removal( alot of our best spring discharges are ironically and tragically taken up by hatcheries. there are other techniques which increase ground water recharge/ maintain ground water in gravel basal layer.
Anglers have dipped Thermometers in streams in the 70’s and confidently declared the whole stream is “to warm for brook trout” now it’s a brown trout stream. This ignores fine scale thermal refuge like seeps and springs that have more favorable temps that allow brook trout to survive these conditions when invasive trout species don’t push them out. You will never hear about any of this from PA fish and boat despite the fact that they are aware of it because they are ignoring the recommendations to change their stocking/non native trout management practices from federal science agencies, brook trout NGO’s, academic brook trout researchers. They ignore this science just to keep the hatchery machine going and keep everyone believing the only factor is the water temp/quality itself, a panacea for all native brook trouts problems. We have really underestimated invasive species(biotic factors) when we think about why a stream does not support healthy brook trout populations in some cases(not all obviously). I know this thread got started because of this decision by PA fish and Boat and an angry fishermen but it’s a public education tragedy. I will give them credit on the right decision to not stock freeman run specifically, but there is SO much more they need to do to transition from social program selling trout stamps into a serious conservation based resource manager including adopting effective fisheries science and educating the angling public they have wronged by pretending to be a resource manager.
