Impiego dei BRUV (Baited Remote Underwater Video) per la valutazione del popolamento ittico nell'area marina protetta Capo Gallo-Isola delle Femmine (Palermo)

Abstract

A Baited Remote Underwater Video (BRUV) system was used to assess fish assemblages on detritic bottoms (40 m) inside and outside the Capo Gallo - Isola delle Femmine MPA. Our study investigated the suitability of Baited Remote Underwater Video to describe fish (relative) abundance and diversity between sites at different protection levels. The fish assemblages relative abundance and species richness significantly differed between the three different location (A, B e CTL) considered. The largest difference occurred at CTL site position outside the MPA, where 2-fold increase in the number of species was recorded relative to the A and B sites.
