“…These results are in agreement with previous observations made in the western Ionian Sea and in other Mediterranean areas (e.g. Abellò et al, 1988;Biagi et al, 1989;Cartes et al, 1994;Abella and Serena, 1995;Stefanescu et al, 1994;Ungaro et al, 1995). They confirm that the transition between an upper slope fauna and a strictly bathyal fauna is located at about 400-500 m (Pérès and Picard, 1964;Abellò et al, 1988;Mura and Cau, 1994).…”

Univariate diversity indices and multivariate analyses (cluster and multidimensional scaling (MDS) were performed in order to evaluate biodiversity in two neighbouring areas of the Eastern Mediterranean with different fishing intensity. Data were collected from two trawl surveys (July and August 2000) in two areas of the Ionian Sea. In the area off the South-eastern Italian coast, there is a trawl fishery at depths between 300 and 700 m that targets the deep-sea shrimps Aristeus antennatus and Aristaeomorpha foliacea. In the other area off Northern Greece, fishing is only carried out down to 400 m depth.While diversity indices did not show convincing differences in the community structure between the two study areas considered as a whole, the multivariate analysis showed a clear pattern linked to depths and areas highlighting the distribution of abundance of the various species. Depth played the main role in the group differentiation, indicating the existence of two quite distinct bathyal faunal assemblages: one on the upper slope, the other on the middle slope. The results of the geographic characterization of the diversity and of the assemblage composition are discussed considering the different fishing intensity as well as the environmental conditions in the two areas of the same basin.

“…Berné et al, 1999;Canals et al, 2004Canals et al, , 2009Puig et al, 2008) as well as to their biodiversity and fishery resources (e.g. Cartes et al, 1994;Stefanescu et al, 1994;Gili et al, 2000;Palanques et al, 2005;Sardà et al, 2009;Farrugio, 2012;Revenga Martinez de Pazos, 2012;Fabri et al, 2014). In the last two decades, the canyons have been investigated as a part of national projects carried out in different countries as well as in the context of European projects designed to gain new insight into the biodiversity, ecosystem structure, and function in the deep sea (e.g.…”

Macro- and megafauna recorded in the submarine Bari Canyon (southern Adriatic, Mediterranean Sea) using different tools

Macro- and megafauna were recorded in the submarine Bari Canyon (southern Adriatic Sea, Mediterranean Sea) during an oceanographic cruise carried out in May-June 2012 and an experimental fishing survey conducted in November 2013. During the former, a total of 20 benthic samples were taken using a Van Veen grab at depths between 268 and 770 m and 4 deployments of a baited lander, for about 43 hours of video records, were carried out at depths between 443 and 788 m. During the latter, 8 longline fishing operations were conducted from 338 down to 612 m. Eighty-five living benthic and benthopelagic species were recorded: 29 Porifera, 1 Cnidaria, 2 Mollusca, 11 Annelida, 1 Arthropoda, 19 Bryozoa, 3 Echinodermata and 19 Chordata. A total of 51 species are new records for the Bari Canyon, 29 new records for the Adriatic Sea. Among the Porifera Cerbaris curvispiculifer is a new addition for the Italian Sponge Fauna. The first certain record of living specimens for the bryozoan Crisia tenella longinodata is reported. A total of 6 Mediterranean endemic species have been identified: 4 Porifera and 2 Annelida. The bathymetric range of some species has been extended. New information acquired for deep sea species confirms their importance in the structure of cold-water coral communities. This study has updated the knowledge on the biodiversity of the Adriatic Sea, as well as of the Bari Canyon in particular, one of the sites designated as “jewels of the Mediterranean” for which urgent conservation measures are needed.

“…In the deep Northwest Medi-terranean Sea, there is a boundary between 350 and 550 m, separating upper and middle slope decapod crustacean communities (Abelló et al, 1988;Cartes et al, 1994). The boundary between the middle and lower slope was established at around 1200 m (Cartes and Sardà, 1992;Cartes, 1993).…”

Information was collected over two seasons on the depth distribution of the deep-water fishes and decapod crustaceans to the southwest of the Balearic Islands. The data were analysed to compare the intensity of faunal change with depth to individual size, measured as mean individual weight, both within and between fish and decapods. The results are discussed on the light of the biological characteristics of the populations studied. We conclude that there are complex distributions of mean weight by depth, determined mainly by trophic aspects and biological adaptations to the oligotrophic environment of the deep Mediterranean.
