Arrowtooth flounder can be found along the Pacific Coast from Northern California to the Gulf of Alaska to the Bering Sea/Aleutian Islands. Males can reach 2 feet in length, and females grow a bit larger, up to almost 3 feet. Flounder is too large to be seared over a stovetop, so roasting is the best way to prepare this delicious fish.
