Peracarid Crusteceans Species from Upper Infralittoral Rocky Shores of Gokceada Island (Aegean Sea)

Abstract

The abundance of the peracarid crustacean fauna were studied on a spatial scale of Gokceada Island which is located Northern Aegean Sea. Samples were collected seasonally from 13 coastal stations at depth 0.1-0.5 m, during years of 2010 and 2011. The surface was scraped by means 20 x 20 cm quadrats and sieving 0.5 mm mesh size. Result of identified and counting all peracarid species, a total of 142,906 individuals/m2 were obtained belonging to 88 species and 66 of them were new record for the island’s fauna. Amphipods were the dominant group both in terms of species Margalef richness and abundance. Ampithoe ramondi, Hyale schmidti and Elasmopus brasiliensis were the most abundant species. Number of species, density, richness, evenness, diversity of stations and similarity are also discussed.
