Abstract The objective of this study was to evaluate whether the Bari Canyon influences the distribution and abundance of fish fauna in the southern Adriatic Sea. Data were collected in the Bari Canyon and in an adjacent area on the continental slope during an experimental longline survey carried out in June 2015. A total of 19 fish species were collected (16 inside and 13 outside the canyon). Differences between the sites were evaluated by means of a set of univariate and multivariate methods (analysis of variance, permutational multivariate analysis of variance, non-metric multidimensional scaling). The abundance and biomass of the whole catch were significantly greater inside than outside the canyon. The most abundant species were the shark Galeus melastomus and the teleost fishes Conger conger, Helicolenus dactylopterus, Merluccius merluccius, Pagellus bogaraveo and Phycis blennoides. All these species were found to be more abundant in the canyon than in the adjacent area. However, a significantly greater abundance inside the canyon than outside was detected for C. conger, while P. blennoides showed both significantly greater abundance and biomass in the canyon than outside. P. bogaraveo was exclusively caught inside the canyon. C. conger and P. blennoides exhibited significant differences in their sizes between the canyon and the adjacent area: a greater number of both smaller and larger individuals were found in the canyon than on the open slope. Mature females and males were mostly observed in the canyon in all the most abundant species, with the exception of P. blennoides due to its autumn-winter spawning. The present study corroborates the role of the Bari Canyon as a refuge area and an Essential Fish Habitat for fish species exploited in the neighbouring fishing grounds, highlighting the need for conservation measures.

This chapter is a review of studies that present the role of cold-water corals as shelter, feeding and life-history critical habitats for fish species in the Mediterranean Sea and world oceans. Studies in the Mediterranean have been carried out both in Madrepora-Lophelia dominated communities and in coral areas characterised by octocorals and black corals. Most studies in the northeast Atlantic regard Lophelia pertusa reefs, while those in the northwest Atlantic refer to Oculina varicosa, L. per...

The objective of this study is to provide additional evidence of the utilization of Cold-Water Corals (CWC) and Submarine Canyons (SC) by fishes as areas for growing to maturity and to reproduce and thus for the classification of CWC as Essential Fish habitats (EFH). Data were collected with longline experimental surveys carried out during spring-summer and autumn-winter from 2010 to 2014, in different CWC sites distributed along the Apulian margin: Gondola Slide (GS), Bari Canyon (BC), Monopoli...

In the last two decades, many new living cold-water coral (CWC) sites throughout the Mediterranean basin have been discovered and investigated. As part of oceanographic cruises, using ROVs and towed cameras, and trawl and longline surveys as well as records from fishermen, a belt of CWC communities has been identified along the Apulian continental margin (Central Mediterranean). The most investigated CWC communities are those of the Santa Maria di Leuca (SML) CWC province (northern Ionian Sea) a...

Abstract A new cold-water coral (CWC) province has been identified in the Mediterranean Sea in the Capo Spartivento canyon system offshore the southern coast of Sardinia. The ‘Sardinia cold-water coral province’ is characterized in the Nora canyon by a spectacular coral growth dominated by the branching scleractinian Madrepora oculata at a depth of 380–460 m. The general biohermal frame is strengthened by the common occurrence of the solitary scleractinian Desmophyllum dianthus and the occasiona...

A long-term lander employing a baited camera system was developed to study temporal variation in the presence of scavenging fish and invertebrates at a cold-water coral community on Galway Mound (Belgica Mound Province, NE Atlantic). The camera system was tested during two successful long-term deployments for periods of 6 and 12 months respectively. The baited system, consisting of two separate video cameras with infrared lights and a bait dispenser with 24 bait positions, recorded more than 15,...

Submarine canyons are major geomorphic features of continental margins around the world. Several recent multidisciplinary projects focused on the study of canyons have considerably increased our understanding of their ecological role, the goods and services they provide to human populations, and the impacts that human activities have on their overall ecological condition. Pressures from human activities include fishing, dumping of land-based mine tailings, and oil and gas extraction. Moreover, h...

New cold-water coral (CWC) sites were recorded along the Apulian margin (Central Mediterranean). The species composition and depth distribution of CWCs were updated. A distribution of the CWC sites coincident with the course of the dense-water masses that flow between the Southern Adriatic and Northern Ionian was confirmed. The faunal assemblages of five of these CWC sites were investigated and compared using experimental longlines during the spring–summer and autumn–winter seasons, between 2010...

Abstract The geographic distributions of many coastal marine fish assemblages are strongly driven by habitat features, particularly among demersal fishes that live along the seafloor. Ecologists have long recognized the importance of characterizing fish habitat associations, especially where spatial management is under consideration. However, little is known about fish distributions and habitat suitability in unique demersal habitats such as submarine canyons. The active continental margin of th...

Abstract The present study represents the first documentation of the trophic spectrum of the deep-water teleost fish Helicolenus dactylopterus in two basins of the central Mediterranean (Northern Ionian and Southern Adriatic) and the first attempt to compare the diets of this deep-water teleost fish between two different habitats: flat muddy seabed and cold-water coral (CWC) habitat. 346 stomachs were collected on muddy bottoms and 352 in CWC habitats. The feeding habit of H. dactylopterus in th...

Abstract The Mediterranean Sea, a land-locked and highly vulnerable sea, is one of the world’s marine basins with the highest concentrations of deep-sea canyons. The knowledge of the biology and ecology of Mediterranean canyons has increased notably in the last 20 years. The present paper aims at summarizing the new knowledge presented in the Special Issue of Progress in Oceanography entitled “Ecology and functioning of Mediterranean submarine canyons”, where multidisciplinary studies in marine ...

: The ecosystem functioning of two marine food webs covering the north-eastern (Salento) and south-western (Calabria) sectors of the North-Western Ionian Sea (NWIS) (Central Mediterranean Sea) was investigated through a food-web model. Data inputs covered a wide set of ecological information applied to 58 functional groups (FGs). The sum of consumption and the mean predation mortality rate were calculated for benthic, demersal, and pelagic subsystems indicating the predator and prey roles of the...

Abstract This review highlights the beneficial influence of cold-water coral habitats and Bari canyon on the abundance of the bentho-pelagic fauna and demersal fisheries along the Apulian continental margin, between the South-western Adriatic and North-western Ionian (Central Mediterranean). Because of its fisheries' value, this geographic area deserves the implementation of a new Fisheries Restricted Area (FRA) for a better governance of the Apulian CWC grounds and related fishery resources.
