Description
Most freshwater and ocean fish can be marinated for only 30 minutes at most—or they turn opaque and are essentially "cooked" before you even go out to the grill. The exception, though, is strong-flavored, oily fish like amberjack, bluefish, salmon, mackerel, marlin, mullet, or even our old standby, farm-raised catfish, which can stand up to longer marinating. In fact, marinating these oily fish for a longer time makes them taste even better.
