Advice for Consumption

Think before consuming this species.

Greek legislation sets an unsustainably small legal minimum size and no closed season, leaving juvenile and spawning fish completely unprotected. Always respect minimum sustainable size limits and do not consume this species during its breeding season.

Archipelagos Tips

Choosing larger, mature fish helps reduce fishing pressure on juvenile individuals.

Description

Has a slender body, reaching up to 60 cm in length but specimens of over 30 cm are rare, likely due to fishing pressure. It has a pointed snout, and like the common mackerel, the dorsal fins are spaced apart. Ventral fins are present on the fromt of the body, at the level of the pectoral fins. The body is covered in small scales, with larger scales at the back of the head and on the pectoral fins. Its swim bladder allows it to quickly dive deep. The body has a bluish-green coloration with yellowish hues and dark spots along the flanks. The belly and lower part of the flanks are white.

It looks like Scomber scombrus (Common mackerel), which differs by its spotted and striped flanks. The eyes are larger and covered with a flap of adipose tissue.

Max length: 64 cm
Max weight: 3 kg
Depth range: 0-300 m

breeding & Growth

Spawning most often occurs at water temperatures of 15° to 20°C.
Growth rate: Moderate (k = 0.3yr⁻¹).
