About Bluefish

Also called snapper blue (Pomatomus saltarix) The bluefish (Pomatomus saltatrix) is the only extant species of the family Pomatomidae. It is a marine pelagic fish found around the world in temperate and subtropical waters, except for the northern Pacific Ocean. Bluefish are known as tailor in Australia and New Zealand, elf and shad in South Africa. It is a popular gamefish and food fish. The bluefish is a moderately proportioned fish, with a broad, forked tail. The spiny first dorsal fin is normally folded back in a groove, as are its pectoral fins. Coloration is a grayish blue-green dorsally, fading to white on the lower sides and belly. Its single row of teeth in each jaw is uniform in size, knife-edged, and sharp. Bluefish commonly range in size from "snappers" of 7 in (18 cm) to much larger, sometimes weighing as much as 40 lb (18 kg), though fish heavier than 20 lb (9 kg) are exceptional.

Taxonomy The bluefish is the only extant species now included in the family Pomatomidae. At one time, gnomefishes were included, but these are now grouped in a separate family, Scombropidae. Extinct relatives of the bluefish include Carangopsis from the Early Eocene of Italy and Lophar from the Late Miocene of Northern California...
