But I think it would actually take a long while though to start off an all PA brook trout strain in hatcheries. We don't have THAT many, due to over fishing and exotic trout. I forget where I read it, but somewhere it said that brown trout are actually getting into native brook trout streams, out competing them, naturally reproducing on their own, and basically kicking them out.
Our native trout are beautiful. I have caught a few juveniles before on rod and reel and while seining, and they're just amazing. And as you said, they are our state fish. You think more would go into protecting them, stocking them, and having our streams known as great brook trout fishing to draw in the money. Now they're starting off a program of stocking along the lines of larger, but fewer. I don't know what's worse...a bigger trout with a bigger appetite, or many, smaller trout with an appetite.
Also while trout fishing, I've seen many anglers actually get frustrated catching suckers and creek chubs, that they just casually kill them everytime they catch them. Yeah, like that's going to help.
Before I was a teenager, I went to a friends house about an hour away, and we got the great idea to stock the local trout stream with bluegill, bass, perch, catfish, and anything else we could catch in a farm pond. Now I know that was a pretty bad idea, but at the time it seemed fun. They're native, and more fun to catch than trout. The opening day of trout, people were catching bluegills left and right, and they were all discouraged and left. Random story, but it shows how much people want to catch trout, not just go fishing for the simple fun and enjoyment. I guess until the day people don't want to trout fish, they're always going to be stocking exotics.
Although, a few years ago there was something like a mercury break out in hatchery raised fish, and a lot of people stopped fishing for them. I know I did. Maybe we should start a fake scare just to get people to stop...

I've read through the booklet about fishing laws they give you every year about 100 times. They don't seem that hard to follow. What does bother me though is every watershed has different regulations. Are their other laws written somewhere else or something?
