I just did a little Bing-ing (like Google-ing but on Bing.com) and what little I found confirms your description of it's being a strong-flavored fish.
Consider soaking the fish in buttermilk for a bit to soften the strong flavor then season with garlic powder, salt and pepper.
Do you grill yours or cook in a pan or oven?
