Yes, they are actually very good eating...but I have lost some to "sinking" in addition to some that have died from time to time trying to escape over spillways. I've also hooked, but never landed one of those 15 pounders.

I approach GC differently than many/most...I try to stock for prevention/maintenance before a problem develops rather than having to stock for a cure after a problem gets out of hand. Curative stocking rates are generally 20 or so per acre, but my preventive rate is no more than 2 per acre. Works for me by keeping the weeds under control, not eliminating them...some weeds are good for fish, the best structure you can get....and rotating 2 GC is much easier than 20.
