The type most commonly found in American markets is the Pacific barracuda (also called California barracuda), which usually ranges from 4 to 8 pounds. It’s a firm-textured fish with a moderate fat content and is best grilled or broiled. Barracuda can be substituted for wahoo or mahi mahi. The great barracuda, whose flesh is often toxic, can weigh over 100 pounds and can exceed 6 feet in length. See also fish.
