Oceanic pelagic fish typically inhabit waters below the continental shelf. Pelagic fishes are those that spend much of their lives swimming in open water away from the bottom. These areas are highly productive and supply nutrients for the growth of plankton which forms the food for the smaller pelagic species. A mackerel is typically less than 2 feet in length. Fourteen-inch fish weigh about 1 pound in the spring and about 1¼ pounds in the fall when they are fat; 18-inch fish weigh about 2 to 2½ pounds; a 22-inch mackerel will likely weigh 4 pounds. Examples of pelagic fish include larger fish such as swordfish, tuna, mackerel, and even sharks. Of these, the mackerel is the smallest. They are found in the Atlantic and Pacific ocean regions.
