I didn't say the cost of stocking doesn't matter. I said the cost of overstocking of Class A waters is insignificant to the overall stocking cost issue.
To play a bit of devil's advocate, I live in Bucks County. Philadelphia and the adjoining counties have but a few miles of class A water. Much of it inaccessible to most fishermen. The area contains about 1/3 of the state population. Why would residents of that area give up trout stocking in favor of habitat investments that would likely be outside their area? Wouldn't that be depriving a lot of people an opportunity to get into trout fishing? Some possibly becoming motivated in supporting programs like brook trout initiatives which have almost no direct impact on SE PA.
Certainly, the cost of stocking is concerning, especially with the numbers of licensees declining. I think people from areas of the state with more wild trout fishing opportunities tend to overlook the value those in other areas place on stocking.
