I think a rolled up newspaper could be made delicious with that recipe.
The big deal about halibut fishing is not so much the meat as the size of the fish. North Americans in particular are all about bigger is better. The
experience of hunting and fishing hardly matters anymore. Float a river when the dogs (chum) or sockeye are running. Just the sight of them filling the water bank to bank is incredible. Or sit on a boat all day to
maybe drag up a hundred pound flat ugly slab off the bottom with a crane for fishing gear? A little nine pound sockeye on a fly will give you everything: runs, jumps, tarpon walk. And you can catch a dozen or more of them in an hour if you know what you're doing, have the right gear, and your arms can take it. Meantime your standing in the most beautiful scenery on earth. Big bears are always about. And otters, eagles, osprey, harlequin ducks, etc. Something to see every second. Or you can sit in a boat looking at water and seagulls sitting on you just for the chance to catch one BIG fish. Blech!
And it's not just fishing. Hunting is all about size these days. No one can sell a story about a 4x4 whitetail buck unless it's shot by a kid or a woman. But that gnarly multipoint droptine freak Mr Realtree shot over bait is definitely publishable. My best kudu is only 44.5" but is prettier than most +50" racks I see on the net. What makes it truly "valuable" is the story was anything but uneventful. Nearly a tragic ending that could have ended my hunting (by choice).
I would encourage the OP to reconsider his king fishing goal. If he's looking for something to replicate for the wall, a big king, even when done up by a good taxidermist like my daughter, is relatively speaking boring to look at. Here's one she did last year.

But hey, she can make lake trout look good!

Catch a bull red sockeye and have it replicated. Now there's a mount that will make your eyes pop. Or better yet, a bull dog salmon. Wow! I call them zombie fish. And I'm sorry but I have to disagree, dog salmon do have plenty of fight. I've eaten them fileted and cooked over the campfire and not bad. Not sockeye or silver good but better than pinks.
