The bluefish is a firm, round, oily fish, similar to mackerel but larger, and exceptionally voracious. It is found in the Mediterranean and in the North Atlantic and is related to the pompano. It is particularly prized in Turkey and the United States where it is known as the bulldog of the sea. Most likely to be 1-1.4 kg (2½-3 lb) in size. It is firm and round with a silver belly and bluish colour on its back. The body is rounded at the shoulders and tapers at the tail. The head is neatly proportioned. The flesh is white, firm and has a delicate flavour but is quite bony. It can be treated as salmon, but subtly flavoured accompaniments are best. The dark strip which runs down its centre should be removed as it imparts a strong fishy flavour.
