>>Anybody else have streams to add? There are plenty in western PA, in the Allegheny and Clarion drainages.>>
There are many, I’m sure. So far as the ANF region is concerned, it seems fairly safe to say that pretty much any currently stocked stream section averaging under 30 feet in width with good water quality and temperature regimes within the brook trout’s tolerance probably has a wild brook trout population that ranges in abundance from incidental to fairly strong, say in the very low class D to mid class B range just to put an estimation quantifier on it. My long term observational guess (with emphasis on the word “guess”) is that far more of these streams are towards the lower or poorer end of this scale than the higher or better end.
There are a lot of things in this overall discussion that need at least some level of agreement in terms of definitions and valuations. To be absolutely frank, one of the first, IMO anyway, is to assign an inherent or intrinsic valuation to the brook trout’s indigenous status. Not everyone agrees as to the degree that the brook trout’s indigenous status should serve as a driver for fisheries management decisions and I have to admit to being a bit conflicted about it myself.
I tend to see the idea of ending all stocking over “any” wild brook trout population as a locomotive of objective single-solution thinking that runs headlong into a stone wall of subjectivity, preferences and situational variation and serves little useful purpose other than being a mustering point for those of like-minded zealotry. That’s fine. This is one of the ways we conduct the policy debate whether we are talking about what to do about immigration, brook trout management or anything else.
I think perhaps what we need to do is test our various beliefs and convictions with a series of studies; here in Pennsylvania, with our brook trout. Noting what New Jersey or Maryland may have done is interesting and perhaps even useful, but of limited utility to us here when we compare the scope of the resource and the prevailing demography between the 3 places. I’d like to see us choose a range of current stream sections across the state where stocking occurs over wild brook trout populations, say 15-20 or so. They should be chosen to reflect as best possible such variables as historic brook trout abundance, angling pressure and current stocking rates and any other relevant factor that would be of value. Stop all stocking in these test sections for (how about) seven years and see what we get. So far as the streams in the ANF region and those on the periphery that I am most familiar with, my guess is that we won’t see significant changes for the better in brook trout abundance in the majority of studied waters. I’d love to be proven wrong, but I don’t think I will be.
And once all this is done and we have the results, one of the issues we can then take under consideration is whether the indigenous status of brook trout in those of the tested waters that did not perform well is important enough to us to reduce the social and angling opportunity values of these waters by deciding to not resume stocking.
I know that this is not the question you asked, but my reply is at least related to your original question and I needed to bag off about all this. Now, I feel better…
