Bluefish
Aggressive marine pelagic fish found in temperate and subtropical waters worldwide.
The bluefish is the sole living member of the Pomatomidae family. It inhabits coastal and open waters across the globe, excluding the northern Pacific. This aggressive predator is valued as both a sport catch and a food source, though its high oil content requires rapid consumption.
- Only extant species in the family Pomatomidae
- Known as tailor in Australia and New Zealand
- Aggressive feeder that engages in surface frenzies
- High mercury content limits recommended consumption
- Migrates seasonally along coastlines worldwide
What it is
This fish is the only extant species within the family Pomatomidae. It possesses a moderately proportioned body with a broad, forked tail. The first dorsal fin and pectoral fins typically fold back into grooves. Its colouration shifts from grayish blue-green on the back to white on the belly. Each jaw holds a single row of uniform, knife-edged teeth. Adults usually measure between 30 and 60 centimetres, though they can reach 130 centimetres and weigh up to 14 kilograms.
Where it lives
Bluefish inhabit temperate and subtropical waters worldwide, excluding the northern Pacific Ocean. They occupy pelagic zones above continental shelves, energetic surf areas, and rocky headlands. These fish also enter estuaries and brackish environments. Along the United States East Coast, they migrate seasonally, moving north in spring and south in autumn. Similar migratory patterns occur off South Africa and in the Black Sea, where populations move through Turkish straits to warmer Mediterranean waters for winter.
How it lives
Adults are strong, fast swimmers that form loose groups. They exhibit aggressive feeding behaviour, often engaging in frenzies against schools of forage fish like menhaden, jacks, and anchovies. They also consume shrimp and squid. Cannibalism occurs, with adults destroying their own young. Predators include tuna, sharks, billfish, seals, and dolphins. Juveniles face threats from striped bass, fluke, and larger bluefish. Their aggression can pose risks to humans, with recorded incidents of bites on swimmers and fishermen.
Breeding and life cycle
Reproduction takes place during spring and summer months. Spawning habits remain poorly understood compared to other marine species. In the western North Atlantic, distinct populations exist separated by Cape Hatteras. Currents such as the Gulf Stream transport fry from southern spawning grounds northward. Eddies may carry these young fish into mid-Atlantic and New England coastal populations. Fry feed on zooplankton and drift with currents, vulnerable to various oceanic predators during this early life stage.
Fish and people
This species is a popular target for recreational anglers and commercial fisheries. In Australia, it is known as tailor and caught along the east and west coasts. Culinary preparations include baking, smoking, or frying smaller snapper blues. Due to high fat content, the flesh rancidifies quickly, requiring immediate refrigeration or preservation in vinegar and wine. It is rich in omega-3 fatty acids but contains elevated mercury and PCB levels. Health agencies advise limited consumption for children and women of childbearing age.
Status and threats
Populations have faced significant pressure from overfishing, particularly in the late 1990s in the US middle Atlantic region. Active management strategies helped rebuild stocks by 2007. Abundance tends to cycle over periods of ten years or more. Conservation efforts include annual fishing bans in Turkey during spawning seasons to protect eggs. Public awareness campaigns and catch limits aim to reduce stress on regional stocks and ensure sustainable numbers for future generations.
Questions people ask about Bluefish
Why is the bluefish called tailor in some countries?
In Australia and New Zealand, the species is commonly referred to as tailor. This local name distinguishes it from other regional varieties. In South Africa, it is known by different names, including elf and shad, reflecting its wide distribution across temperate and subtropical waters.
Is it safe to eat bluefish regularly?
Bluefish contains high levels of mercury and PCBs, averaging 0.4 ppm. Due to these contaminants, health authorities recommend that young children and women of childbearing age limit intake to one serving per week. The flesh also spoils rapidly due to high oil content, requiring quick consumption.
How large do bluefish typically grow?
Most adult bluefish range from 30 to 60 centimetres in length. However, they can reach a maximum size of 130 centimetres and weigh up to 14 kilograms. Fish exceeding 9 kilograms are considered exceptional catches in recreational and commercial fisheries.
Are bluefish dangerous to humans?
Yes, they are aggressive predators with sharp, knife-edged teeth. They have been known to inflict severe bites on fishermen handling them. There are also recorded incidents of attacks on swimmers and waders in shallow water during feeding frenzies, posing a risk in surf zones.
