Dicentrarchus

Dicentrarchus is a genus of fish belonging to the family Moronidae, commonly known as sea basses. This genus comprises two species, the European sea bass (Dicentrarchus labrax) and the meagre (Dicentrarchus punctatus). These species are characterized by their elongated bodies and distinct features like the two black spots near the base of the dorsal fin, which gave rise to their scientific name (“di” meaning two, and “kentron” meaning a spur). Dicentrarchus species are economically significant, being widely cultured and prized for their delicious flesh.

Common Names

The common names for Dicentrarchus species vary depending on the region and language. The European sea bass is also known as sea bass, European bass, branzino (Italy), lubina (Spain), loup de mer (France), and robalo (Portugal). The meagre is called meagre, corvina, or stone bass. These common names can often overlap, leading to confusion, so it's best to use the scientific name, Dicentrarchus, to ensure clarity.

Characteristics

Dicentrarchus species share several characteristics. They typically have a silvery-grey to bronze coloration with darker backs and sides, and they can reach lengths of up to 1 meter. They have a distinctive elongated body shape, a large mouth with sharp teeth, and two dorsal fins, the first of which is spiny. Both species are carnivorous, feeding mainly on crustaceans, fish, and cephalopods.

Environment

Both Dicentrarchus species are found in the northeastern Atlantic Ocean, Mediterranean Sea, and Black Sea. They prefer coastal areas, estuaries, and brackish waters. The European sea bass is more tolerant of fresh water and can be found further inland than the meagre. Both species are highly adaptable and have successfully colonized various habitats.
