Osservazioni sulla diversità della fauna ittica costiera in zone soggette a differenti regimi di tutela nell’Area Marina Protetta dell’Isola dell’Asinara

In order to assess the effects of protection, coastal fish assemblages from 3 zones with different protection levels were investigated by visual census in 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 of Diplodus sargus and D. vulgaris in the 3 zones, due to both the protection measures and the geographic exposure, were found.
