. By October, they leave the waters north of New York City, heading south (whereas some bluefish, perhaps less migratory, are present in the Gulf of Mexico throughout the year). In a similar pattern overall, the economically significant population that spawns in Europe's Black Sea migrates south through Istanbul (Bosphorus, Sea of Marmara, Dardanelles, Aegean Sea) and on toward Turkey's Mediterranean coast in the autumn for the cold season. Along the South African coast and environs, movement patterns are roughly in parallel.

In turn, bluefish are preyed upon by larger predators at all stages of their lifecycle. As juveniles, they fall victim to a wide variety of oceanic predators, including striped bass, larger bluefish, fluke (summer flounder), weakfish, tuna, sharks, rays, and dolphins. As adults, bluefish are taken by tuna, sharks, billfish, seals, sea lions, dolphins, porpoises, and many other species.

Recreational fisheries
In Australia, bluefish, called "tailor", are caught on the west coast from Exmouth to Albany, with the most productive fishing areas being in the west coast bioregion.
The IGFA All Tackle World Record for bluefish stands at 31 lb 12oz (14.4 kg) landed by James Hussey near Hatteras, North Carolina.
Commercial fisheries
In the U.S., bluefish are landed primarily in recreational fisheries, but important commercial fisheries also exist in temperate and subtropical waters.
Bluefish population abundance is typically cyclical, with abundance varying widely over a span of 10 years or more.[Ulanski, Stan (2011]

Management
Bluefish is a popular sport and food fish, and has been widely overfished. Fisheries management has generally stabilized its population. In the middle Atlantic region of the U.S., bluefish were heavily overfished in the late 1990s, but active management rebuilt the stock

''FishWatch'', NOAA. Retrieved 5 October 2012. Elsewhere, public awareness efforts, such as bluefish festivals, combined with catch limits, may be having positive effects in reducing the stress on the regional stocks.
Culinary use
Bluefish may be baked or poached,[Davidson, Alan (2002) ''Mediterranean Seafood'', 3rd ed. , p. 100] or smoked. The smaller ones ("snapper blues") are generally fried, as they are not very oily.[Davidson, Alan (1980) ''North Atlantic Seafood''. , pp. 92-93]
Because of its fattiness, bluefish goes rancid rapidly, so it is generally not found far from its fisheries, but where it is available, it is often inexpensive. It must be refrigerated and consumed soon after purchase; some recipes call for keeping it in vinegar and wine before cooking, in ''vina d'alhos'' or ''en escabeche
