Crustacea Decapoda associated with Brachidontes pharaonis (P. Fischer, 1870) (Mollusca, Bivalvia) beds from the Levantine coasts of Turkey

Abstract

[The spatial distribution of the decapod crustacean fauna associated with Brachidontes pharaonis (Mollusca, Bivalvia) beds from the Levantine coasts of Turkey was studied in September 2005. Triplicate samples were collected by means of a quadrate sampler covering 400 cm2 at nine intertidal stations located between Iskenderun Bay and Antalya Bay. A total of 13 species, represented by 61 individuals was identified. Among these, Pachygrapsus marmoratus was the most dominant species represented with 19 individuals. P. marmoratus and Pilumnus hirtellus were the most frequent decapod species on the mussel beds with 25.9% occurrence. La repartition spatiale de la faune de crustaces decapodes associee aux moulieres de Brachidontes pharaonis (Mollusca, Bivalvia) des cotes levantines de Turquie a ete etudiee en septembre 2005. Des echantillons en triple ont ete collectes au moyen d'un echantillonneur carre couvrant 400 cm2 dans neuf stations intertidales situees entre la baie d'Iskenderun et la baie d'Antalya. Un total de treize especes, represente par 61 individus a ete identifie. Parmi ceux-ci, Pachygrapsus marmoratus etait l'espece dominante avec 19 individus. P. marmoratus et Pilumnus hirtellus etaient les especes de decapodes les plus souvent presentes dans les moulieres avec une frequence de 25,9%., The spatial distribution of the decapod crustacean fauna associated with Brachidontes pharaonis (Mollusca, Bivalvia) beds from the Levantine coasts of Turkey was studied in September 2005.
