To me, preparing the fish you catch is almost as good as catching it (keyword almost).
Fish:

First, this is my favorite way to cook yellowtail (I'm more of a sushi guy) other than smoking it of course.
Give yourself a couple of cleaned steaks, I like to keep them relatively thin to make grilling easier.
Next, lather those suckers in olive oil and throw some garlic, chili powder, salt and lemon on them
Then it's as simple as throwing them on the grill on medium heat for around 3 minutes per side, be careful not to overcook them
Now to the good stuff. My favorite way to eat yellowtail is simple caveman style with ample wasabi and soy sauce
Sushi is a close second, and I like this simple, just avocado and fish is my favorite
Sometimes you need to give it a little crunch
Excuse the presentation, I tried!!
Now all that's left to do is feast!!!
