HERE COMES THE SHERIFF!
Not going to delete the thread, just going to lock it. Why? Despite a need for a wrist slapping for a few here, it brings up a point that anglers need to consider when you catch that fish of the lifetime and I think it's important to pass the message along, but I'll put an end to the crap.
DBadger ... glad to hear you let almost all your wild steelhead go ... perhaps someday for the sake of the fish you'll let them ALL go.
This is a time when are fish (wild steelhead) are under lots and lots of pressure ... doesn't matter what river you are on, it's there everywhere, just to varying degrees, and basically going downhill all the time. Nets, a doubling of the state population and subsequent angling pressure increase, pollution, stream warming, and so on, you get the picture.
SO, you catch the fish of a lifetime, a thirty pounder ... it's a great feeling, I know. (A little sidebar- I've landed one on gear, lost a couple of others close to that size, landed some nearly as big on the fly, and lost one that made the thirty look puny on the fly ... but that one fish is a great memory. And it swam away, and it's perhaps the most rewarding moment of my steelheading career).
Back to the lesson here .. that thrity pound fish. Perhaps a one in a thousand fish, 0.1% of the population in general? Probably! So here you have one the rarest genetic makeups of the steelhead population ... a fish that either spent four years at sea or spent three years with a longer freshwater residence to begin with. A nearly unique individual on his way to pass these special traits along to the next generation ... and you have the opportunity to allow it to do so with no loss to your memories of the fish ... pictures, artificial mounts will last much longer than your skin mount, especially if you didn't spend the $30-35 an inch to get one of the state's real artists to do it.
Your reasoning is backwards here, if you're ever going to kill a wild steelhead - the best bet is to take an average member of the population ... odds of hurting the run's makeup are the least. So, tell us all about how many other fish you've released, you killed the one that the stock needed the most
