[The brachyuran (Decapoda) taxocoenosis of a shallow meadow of Zostera marina was studied in a coastal area of the Sinop Peninsula (southern Black Sea, Turkey). Specimens were collected monthly between February 2002 and January 2003 with a beam trawl at depths of 5-20 m during benthic surveys carried out off the Sinop coast. A total of 3206 individuals belonging to 9 species was collected. The structure of the taxocoenosis along the year is dominated by portunid crabs; among these, Liocarcinus vernalis (Risso, 1816) is the most dominant species (36.87%). The largest Brachyura community in the Zostera marina beds was recorded in the summer months (June and July). La taxocenose de crabes (Decapoda) d'un herbier peu profond a Zostera marina a ete etudiee dans une region cotiere de la peninsule de Sinop (mer Noire meridionale, Turquie). Les specimens ont ete collectees chaque mois, entre fevrier 2002 et janvier 2003 a l'aide d'un chalut a perche a des profondeurs de 5 a 20 m au cours des campagnes benthiques menees au large de la cote de Sinop. Un total de 3206 individus appartenant a 9 especes a ete collecte. La structure de la taxocenose tout au long de l'annee est dominee par les crabes Portunidae; parmi ceux-ci, Liocarcinus vernalis (Risso, 1816) est l'espece dominante (36,87%). La communaute de brachyoures la plus dense dans les lits de Zostera marina a ete observee au cours des mois d'ete (juin et juillet)., The brachyuran (Decapoda) taxocoenosis of a shallow meadow of Zostera marina was studied in a coastal area of the Sinop Peninsula (southern Black Sea, Turkey).
