I'm more of a purist and prefer not to stock anything that's non-native to my ponds' regions.

However, after many years of resisting, I stocked HSB, and it's been great. I guess I also stocked some blue catfish which may not be native to W. PA.

I agree with Boon about winter kill though. In Hawaii, tilapia have denuded a lot of lakes after introduction.
