VERTICAL DYNAMICS OF MACROZOOBENTHOS ALONG EMINE TRANSECT (WESTERN BLACK SEA REGION)
Sonya Uzunova
Abstract: Investigations of macrozoobenthos at a distance of the coat 1-10 miles along Emine transect were carried out in 2009 aiming to study the vertical dynamics of its quantitative parameters in comparison to the eutrophicated period. Grab samples from a depth range 37-59 m were collected. After laboratory processing total of 39 taxa from Polycheta, Mollusca, Crustacea и “Varia” were identified. The analyses results established Polychaeta as dominant group in species number and abundance, while Mollusca had leading position in biomass formation. Comparison with the former data show reduction in species composition of Mollusca and abundance close to one of 1982. Statistical indices define good ecological status of the water body.
