The species composition and abundance of benthic macroinvertebrates in the Eastern Black Sea
were determined seasonally, between May 2013 and February 2014. Sediment was collected
using a Van Veen grab, at different depths: 5–15 m, 15–25 m, 25–35 m and >35 m. A total of
320 hauls were undertaken at 80 stations, and 90 species were identified, from seven phyla
and 47 families. Overall, Mollusca was the most diverse phylum, with 32 species, followed by
Annelida (32) and Arthropoda (13). The most abundant species was Chamelea gallina, which
accounted for 37% of the total number of individuals, followed by Gouldia minima (25%) and
Pitar rudis (10%). Based on seasonal variations, 62 species were identified in winter, 59 in
summer, 54 in spring and 46 in autumn. The highest abundance was recorded in summer,
representing 37.8% of the total abundance, followed by spring (25.2%). The species with the
highest abundance in all four seasons was C. gallina followed by G. minima. Also, C. gallina
followed by G. minima was the most abundant species in Samsun, Ordu, Giresun and
Trabzon, whereas in Rize and Artvin, the most abundant species was G. minima followed by
C. gallina. The results of this study should provide baseline data for future monitoring, to
understand the consequences of natural or anthropogenic disturbance on the species
composition and abundance pattern of the benthic macroinvertebrate community along the
coast of the Eastern Black Sea.
