The turbot Psetta maeotica (Pallas, 1814) is a demersal species that populates the RomanianBlack Sea’s continental shelf and is an important segment of the regional fishing potential under theaspect of market demand, both on the national and international level. Being a migratory species (short,coast - perpendicular migrations, made for reproduction) it uses during its complete biological cyclevarious habitat types, among which we mention: reproduction habitats (coastal waters, down to 30meters depth), growing habitats (close to the sea bottom, down to 50-60 meters depth), winteringhabitats (close to the sea bottom, down to 60-80 meters depth). The turbot populates almost all thehabitat types present down to these depths, but it prefers the sandy and muddy ones, that are foundespecially in the Central and Northern part of Romanian littoral. The physical, chemical and biologicalcharacterization of these habitats revealed an improving tendency, that appeared on the bases ofeconomical activities restructuring, the growing of the exigencies in implementing the environmentalpolicies, the setting-up of marine protected areas and also the new reglementations regarding the marineresources exploitation.
