I would concur with the sentiment that the amount of brood stock has proportionately gone down, in the general regs sections. We used to scout out Big Beaver Creek here in Lancaster County, for opening day, and base our start point on the number of breeders there. However, the size and quantity of breeders has definitely diminished over the past five years. I do think there are more golden rainbows, but you can see them and that sells licenses. I somehow manage to catch one each year, although I pretty much hate them, and would much rather tie into a nice 'bow or brown. I remember the brood stocking on '08 on the W. Branch of the Octorara; unsettling almost. There was also a time, maybe seven years ago, or so, when the hatcheries had to dump biomass, and a bunch of nice hefty two-year old trout made there way into Fishing Creek and Hammer Creek late season. That was fun for a bit too, to get into some pods of 16-18" fish.
That being said, I caught two hogs of brook trout last year, from an in-season stocking on an all-season stream somewhere in the state. So they do put them in, just not in the quantities they used to. The other one is the license seller. The best part was having my daughter along with me for all three fish.
