Trout is trash fish anyways. I just toss them back in the lake unless somebody asks me for some smoker sized ones.
I strongly suspect you are only used to dealing with one type of trout.
I grew up consuming a significant portion of my protein as wild game. That's because we were on the Big Lake every Saturday and Sunday it seemed, then the rivers in the fall, then ice-fishing....
So, a chest freezer. Also, canning. Canned salmon and trout is pretty damned good. Canned fish makes excellent fish patties. You can make fish patties out of Trout by adding some fat to the mix.
Lake Trout tend to be fatty. You should not be keeping them if you don't like them and won't eat them. Learn how to clean them up.
We threw our Lake Trout back because they're not that good. Canning still works on them because it provides the opportunity to make patties. The pressure-cooking process removes an enormous amount of the 'negative' fish flavor. Plus I guess being essentially rinsed, but you should be maximizing your fish/water ratio as you go along. Still, you'd be surprised how well it improves less desirable species of fish.
Why are fish patties so damned good? Because it's the same things as a meatloaf or meatball: You put a bunch of stuff in there to go with whatever fish you're dealing with, and it fries up exactly the same way as a hamburger patty. You should be able to get it to work on the grill as well with saltines and egg. You can use butter, lard, or anything else you'd make a meat patty stick with. Bread heels dried out and crunched up. Then spices, seasoning and herbs.
I like canned fish patties with Saltines, an egg for about 1 Qt jar, some minced green pepper and minced onion. Fried in an iron skillet with good fat or oil.
The same thing at a restaurant will cost you $9 per patty.
Canning dude. If you're a big fisherman that keeps your catch, I don't see how you can get by w/o it after you've filled the chest freezer.
The amount of fish I've eaten and the mercury therein might reasonably explain much of my adult behavior. Believe me, I've eaten a LOT of fish.
