Marine litter in an EBSA (Ecologically or Biologically Significant Area) of the central Mediterranean Sea: Abundance, composition, impact on benthic species and basis for monitoring entanglement.

Marine litter is commonly observed everywhere in the ocean. In this study, we analyzed 17 km of video footage, collected by a Remotely Operated Vehicle (ROV) at depths ranging between 20 and 220 m, during 19 transects performed on the rocky banks of the Straits of Sicily. Recently, the Contracting Parties of the Convention on Biological Diversity (CBD) recognized this site as an Ecologically or Biologically Significant Area (EBSA).

Mediterranean banks in EBSA area: Hotspots of biodiversity under threat.

This study demonstrates that, in the Central Mediterranean Sea, the Graham, Nereo and Pantelleria Vecchia Banks of the Strait of Sicily represent, in the wide and diversified 'Sicily Channel' Ecological or Biological Significant Area, unknown hot spots of biodiversity threatened by human activities. The investigated banks show an high ecological and biological value (EBV), assessed through presence/absence of specific indicators. The ecological groups of Graham Bank show the maximum EBV; the same as Nereo and Pantelleria Vecchia, except for the benthic component.

Fish Distribution and Habitat Complexity on Banks of the Strait of Sicily (Central Mediterranean Sea) from Remotely-Operated Vehicle (ROV) Explorations.

The Strait of Sicily was recognized internationally as an "Ecologically or Biologically Significant Area" by the Contracting Parties of the Convention on Biological Diversity in 2014. However, basic aspects of its fish diversity are still unknown and most of the information comes from traditional trawl surveys. This paper provides the first detailed description, using a Remotely Operated Vehicle (ROV), of the composition and depth distribution of the demersal fish assemblages found on banks of the Strait of Sicily and the related habitat complexity from 35 to 240 m depth.
