Introduction
The annular seabream, Diplodus annularis, is found on the east coast of the Atlantic Ocean, from Mauritania to Brittany. It is also present in the Black Sea and the Mediterranean.
Its abundance varies depending on the regions and fishing pressure. Easily observed from the surface, it is a good indicator of the quality of coastal marine ecosystems.

How to recognize the annular seabream ?
The annular seabream has a flat, oval body. It ranges in size from 12 to 27.5 centimeters.
The coloration is light gray with silvery and greenish reflections, the top of the head and the base of the caudal fin are slightly yellowish. The pelvic fins are yellow as well as the first rays of the anal fin. A black spot is present on the caudal peduncle.
Juveniles are generally yellow. This color gives way to silvery gray as they grow (from tail to head).
Sexual dimorphism
Male and female are not easily distinguishable. Although the sexes are separate, cases of protandrous hermaphroditism have been reported.

Way of livingdiurnal
The annular seabream generally lives in small groups. It is sometimes observed alone. It is a territorial fish and it is not uncommon to observe fights between two specimens.
In nature, this small predator feeds on mussels and other invertebrates in rocky areas. The powerful dentition of this species allows it to break shells and sea urchins.
Reproduction
Sexual maturity occurs at around 2 years, with a size of about 10 centimeters.
Spawning depends on the water temperature. It occurs from April to June for Atlantic populations and until July-September for Black Sea populations.
The larvae are planktonic and juveniles are observable up to 15 meters deep.

Biotope presentation
The annular seabream is most commonly found at depths less than 90 meters. It is common at shallow depths (10-15 meters) and can be observed near the surface.
This species lives near rocky areas and above seagrass beds. Annular seabream can also be observed in lagoons and ports.
