Osservazioni sulla diversità della fauna ittica costiera in zone soggette a differenti regimi di tutela nell'area marina protetta dell'isola dell'Asinara = Observations on the diversity of coastal fish fauna in zones with different protection measures in the Asinara Island marine protected area

In order to assess the effects of protection, coastal fish assemblages from 3 zones with different protection levels were investigated by visualcensusin the Asinara Island MPA (North-western Sardinia). On the whole 45 species of Teleosts from 18 families were observed. Labrids and Sparids were more abundant in both species richness and density. Significant differences in densities ofDiplodus sargusandD. vulgarisin the 3 zones, due to both the protection measures and the geographic exposure, were found.
