Mahi mahi is also called dolphinfish or dorado, but don't confuse it with dolphin (which as you know is a mammal, not a fish). Its Hawaiian name, referring to its swimming ability, means "extra strong."
Because mahi are prolific breeders and fast growers, their population is both stable and sustainable. Their pinkish translucent flesh has a sweet, delicate flavor, moderately firm texture, and large, moist flakes.
Seafood Watch rates mahi mahi a "Good Alternative.” Moderate mercury level. Kosher.
