I like any kind of fish cooked most ways as long as it is not overcooked, but my favorite ways of cooking fish while camping is to blacken it. I have an old Coleman gas stove a rectangular grill plate which I get smoking hot, pour some olive oil on plate until it smokes pour excess off then place fish fillets on griddle that has been seasoned and sear each side. Salmon,trout,blue fish,mackerel or any oily fish is good this way. The high heat drives the seasoning into the flesh so you don't need a lot. The outside will be blacked but the inside moist.
