Bluefish

Pomatomus saltatrix, the "Skipjack,” “Green fish," or "Horse mackerel." It migrates in schools, n. in the spring, and s. into deeper water in the autumn. Its main food is the Menhaden, the schools of which it follows, but all smaller fishes are voraciously attacked, and often more killed than are eaten. Prof. Baird has estimated that in a single season more than 300,000,000,000 pounds of fish are thus destroyed. They weigh from 3 to 15 lbs., and are caught by trolling with a spoon-hook and line. When fresh, one of the most esteemed of our food fishes. See ACANTH OPTER I.
