Bony Fish

Identification & Biology

  • IdentificationElongated, compressed body with a blue-green back and silver flanks. A line of enlarged scutes along the rear lateral line. Large eyes. Very similar to the blue runner but with a more elongated body.
  • SizeUp to 60 cm total length, commonly 20 to 35 cm.
  • Social HabitSchooling species that forms fast-moving aggregations in coastal and offshore waters.
  • HabitatPelagic in coastal waters, often near the bottom during the day and nearer the surface at night.
  • Depth5 to 100 m, most common between 10 and 50 m.
  • Feeds OnSmall fish, crustaceans, and squid caught in the water column.
  • DistributionEastern Atlantic from Portugal to Angola, including the Mediterranean Sea.
  • DescriptionA fast-swimming jack that is often confused with other carangid species due to its similar appearance. False scads move in large schools through Mediterranean coastal waters, providing food for larger predators. Less commonly encountered by divers than horse mackerel.

Range

Habitat & Distribution

Found in coastal and offshore pelagic waters from the surface down to about 80 m. Prefers areas over sandy or muddy bottoms near the continental shelf edge.

Detail

Preferred Environment

Favours warm temperate waters along continental shelves. Commonly encountered in mid-water schools over open substrate and around harbour entrances.

Encounter Tips

Best approached slowly and calmly. Avoid casting shadows directly over the animal. Neutral buoyancy and patience increase encounter success significantly.

Biology

Behaviour & Diet

Feeding Strategy

Feeds on small fish, planktonic crustaceans, and invertebrate larvae. Schools move through the water column following prey concentrations at different depths.

Opportunistic hunter

Reproduction

Spawns in open water during spring and summer. Fertilised eggs are buoyant and develop within the plankton before juveniles migrate inshore.

Pelagic spawner

Behaviour & Defence

Forms dense schools that make it difficult for predators to single out individuals. Can accelerate rapidly thanks to its forked tail and compressed body.
