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.

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 Many fish species are well-known obligatory inhabitants of shallow-water tropical coral reefs but such associations are difficult to study in deep-water environments. We address the association between two deep-sea fish with low mobility and large sessile invertebrates using a compilation of 20 years of unpublished in situ observations. Data were collected on Northeast Atlantic (NEA) island slopes and seamounts, from the Azores to the Canary Islands, comprising 127 new records of the ci...

Autonomous photographic landers are a low-impact survey method for the assessment of mobile fauna in situations where methods such as trawling are not feasible or ethical. Three institutions collaborated through the CoralFISH project, each using differing lander systems, to assess the effects of cold‐water corals on fish diversity and density. The Biogenic Reef Ichthyofauna Lander (BRIL, Oceanlab), Autonomous Lander for Biological Experiments (ALBEX, NIOZ) and the Marine Environment MOnitoring s...

Abstract The Santa Maria di Leuca (SML) cold-water coral (CWC) province is a proposed priority conservation area according to several conservation initiatives in the Mediterranean Sea. Part of it is a Fisheries Restricted Area (FRA). Anthropogenic impacts due to fishing on this FRA were investigated using a towed camera system during 2005. The geographic distribution of fishing effort in the SML CWC province was examined through an observers’ program of longline and trawl fishing activities duri...

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...

The Santa Maria di Leuca (SML) cold-water coral province (northern Ionian Sea) has the largest occurrence of a living white coral community currently known in the Mediterranean Sea. Madrepora oculata and Lophelia pertusa, identified as marking sensitive habitats of relevance by the General Fisheries Commission for the Mediterranean, have been observed heterogeneously distributed on the summits of several mounds. This particularly patchy and uneven distribution in addition to their importance for...

Abstract The present study represents the first documentation of the trophic spectrum of the deep-water bony fish Pagellus bogaraveo in two different habitats in the central Mediterranean Sea: muddy bottoms (MB) and cold-water coral (CWC) habitats. A total of 133 stomachs were collected on MB and 39 in CWC habitats. The feeding habit of P. bogaraveo was different in the two investigated habitats. A lower number of prey categories were found in CWC habitats (15) than on MB (36). Teleostei (%PSIRI...

Abstract The bamboo coral Isidella elongata is a key structuring species on deep muddy bottoms, which has suffered severe consequences from bottom-fishing activities, as it often co-occurs with precious fishery resources such as red shrimps. A five-year series of data collected during a scientific trawl survey was used to localize the presence and to characterize the associated megafauna over a wide spatial scale in the Western and Central Mediterranean (Sardinia, South-Central Tyrrhenian, Weste...

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...
