Common dentex

What it is

This marine ray-finned fish belongs to the seabream family. It has an oval, compressed body with a smoothly rounded head profile in adults. The mouth sits low and points slightly upward, housing rows of canine-like teeth. The front teeth are the largest, giving the species its name. Young fish appear greyish with black spots, turning pink as they mature. Older specimens become bluish-grey with fading spots. The dorsal fin has eleven spines and soft rays, while the anal fin has three spines.

Where it lives

Its range covers the northeastern Atlantic from the Bay of Biscay to Mauritania, including Madeira and the Canaries. It is rare near the British Isles. The species inhabits the entire Mediterranean Sea and extends into the western Black Sea. It lives near the sea floor over rocky bottoms in coastal waters. While found at depths up to 200 metres, it is most common between 15 and 50 metres.

How it lives

An active predator, it hunts other fish, molluscs, and cephalopods. Juveniles form schools, but adults are mostly solitary. During spring, mature individuals gather in groups for a few weeks to reproduce in warmer surface waters. Studies indicate no size difference between sexes. Most are separate sexes, though hermaphroditism occurs. They reach sexual maturity between two and four years of age.

Breeding and life cycle

Spawning takes place in spring when water temperatures rise. Adults congregate briefly for reproduction before returning to solitary habits. Both males and females mature at two to four years old. While primarily gonochoristic, some individuals exhibit hermaphroditic traits. The species has a life history marked by slow growth and longevity, which affects its reproductive recovery rates.

Fish and people

Highly valued for food and sport, this fish commands high commercial prices. Anglers target it using lines, traps, and nets. Bottom trawling also captures significant numbers. Aquaculture production occurs in Spain and Bosnia and Herzegovina. Its popularity in recreational fishing adds pressure to wild stocks. Traditional fisheries have relied on this species for centuries due to its quality meat.

Status and threats

The International Union for Conservation of Nature lists it as Vulnerable. Populations dropped by over thirty percent across three generations up to 2009. Catches in the Mediterranean fell by thirty-seven percent, with sharper declines in West Africa. Marine protected areas show higher abundance, suggesting protection helps. Slow growth and late maturity make it sensitive to overfishing.
