Some very impressive catches in this thread!
At the risk of sounding preachy, I would encourage anyone who finds themselves with a fish the size of some of the ones posted here to consider releasing it, so it can have a chance to spawn and propagate future generations of fish of similar size. Keep the big ones in the gene pool! With that said, you are of course well within your rights to bonk any legal-sized fish you land legally, and I understand that releasing a fish doesnt guarantee it makes it to the spawning grounds, but it does at least give it a chance.
In my experience, a 15-25 lber yields better quality meat than most larger fish anyways, though to be fair Ive never eaten a 50 lb salmon.
