Don't get the wrong impression by my comment about killing the WRB. If I could possibly somehow keep it alive, I would. Here are the scenarios that start to unfold though....

Say you catch a fish on a bed and you weigh it on your certified handheld scale and it registeres 22lbs 9oz. You put the fish in your 100qt cooler livewell to keep it alive and you run to the marina. You take the fish out and weigh it on dry land (an IGFA rule) with your certified scale hanging from a fixed object so the weight is totally accurate. The fish weighs 22lbs 9oz and you have a witness and everything. You think awesome I just got the world record.

Then you put the fish back in the cooler to keep it alive while you wait for DFG to show up so you can get the state record. DFG takes two hours to show up. Meanwhile the fish barfs up a trout in your livewell. Now the fish gets weighed again and it weighs 22lbs 1oz. HMMMM dilemma huh! DFG is gonna say the fish weighed 22lbs 1oz. But you have a photo of the scale reading 22lbs 9oz and impartial witnesses to prove it.

Then the story hits the internet. Then it gets distored 10 different ways like a bad game of telephone. Pretty soon you got controversy city on your hands. Pretty soon it was you who stuffed the trout down its throat. Pretty soon you were using live trout for bait. It sucks, but that's reality. That's why my advice if you get the world record is to kill it immediately unless you are absolutely positive you can get a certified weight with DFG witnesses before the fish loses any weight. If I caught a 24lb fish, dude I'd try to keep it alive and negotiate selling it to Bass Pro Shops so a million people could see her, but I think its a lot more likely someone will get a fish that barely breaks it than a fish that breaks it by 2 or 3 pounds.

Food for thought if you haven't considered all the possibilities :)
