Abstract Deep-water fishing activities are impacting deep-water habitats worldwide, yet the extent of the damage caused is mainly unseen and not quantified. We used Remotely Operated Vehicle surveys to assess the extent of fishing impacts on rocky substrata on four offshore banks between 70 and 280 m depth in the Mediterranean Sea. Video analysis of the abundance and diversity of megafauna revealed communities dominated by arborescent cnidarian passive suspension feeders at all studied depth… Expand
Distribution and assessment of marine debris in the deep Tyrrhenian Sea (NW Mediterranean Sea, Italy).
A quantitative assessment of debris present in the deep seafloor was carried out in 26 areas off the coast of three Italian regions in the Tyrrhenian Sea, using a Remotely Operated Vehicle (ROV). Expand
Impact of fishing activities on different coralligenous assemblages of Gulf of Naples (Italy)
Coralligenous bioconstructions are among the most important Mediterranean habitats for biodiversity maintenance. However some characteristic and sensitive organisms, such as the fan corals, areExpand
Artisanal fishing impact on deep coralligenous animal forests: A Mediterranean case study of marine vulnerability
Abstract Vulnerable Marine Ecosystems (VMEs) are characterized by prominent biological features susceptible to anthropogenic disturbances. Following international guidelines, the identification andExpand
High Coral Bycatch in Bottom-Set Gillnet Coastal Fisheries Reveals Rich Coral Habitats in Southern Portugal
Bottom-contact fisheries are unquestionably one of the main threats to the ecological integrity and functioning of deep-sea and circalittoral ecosystems, notably cold-water corals (CWC) and coralExpand
Assessment and distribution of seafloor litter on the deep Ligurian continental shelf and shelf break (NW Mediterranean Sea).
Describing seafloor litter in the mesophotic depth range of the Ligurian Sea, one of the most urbanized basins of the Mediterranean Sea, indicates the urgency for specific actions to prevent further spreading. Expand
Animal Forests in Deep Coastal Bottoms and Continental Shelf of the Mediterranean Sea
Several studies using Remotely Operated Vehicles and manned submersibles have recently provided quantitative information on animal forests dominated by gorgonians, black corals, and sponges dwellingExpand
On the effects of recreational SCUBA diving on fragile benthic species: The Portofino MPA (NW Mediterranean Sea) case study
Abstract The main aims of Marine Protected Areas (MPAs) are the conservation of natural habitats and their biological resources, together with the promotion of an eco-compatible economic fruition. InExpand
Deep Gorgonians and Corals of the Mediterranean Sea
Recent studies, carried out by means of innovative technological tools as remotely oper‐ ated vehicles (ROVs), have highlighted the richness of the Mediterranean deep‐sea environments, characterizedExpand
The impact of marine litter from fish aggregation devices on vulnerable marine benthic habitats of the central Mediterranean Sea.
The results of this research will assist in the monitoring of "impact/harm" to the coral and other benthic communities, as recommended by the Marine Strategy Framework Directive and by the Integrated Monitoring and Assessment Programme. Expand
Strandings of NE Atlantic gorgonians
Abstract Northeast coral gardens provide vital breeding and feeding habitats for fishes of conservation and commercial importance. Such habitats are increasingly at risk of destruction as a result ofExpand


The deep-water coral Lophelia pertusa in Norwegian waters: distribution and fishery impacts
The results show that the corals are abundant particularly on the mid Norwegian continental shelf between 200 and 400 m depth, and in general it seems that the largest densities are distributed along the continental break and at ridges of morainic origin. Expand
A quantitative analysis of fishing impacts on shelf-sea benthos.
It is shown that inter-tidal dredging and scallop dredging have the greatest initial effects on benthic biota, while trawling has less effect, and fauna in stable gravel, mud and biogenic habitats are more adversely affected than those in less consolidated coarse sediments. Expand
Most of the major impacts of fishing on the ecosystems recorded around the world occur in the Mediterranean. They vary from local effects on the sea bottom caused by trawler gears to large-scaleExpand
Disturbance of the Seabed by Mobile Fishing Gear: A Comparison to Forest Clearcutting
Bottom trawling and use of other mobile fishing gear have effects on the seabed that resemble forest clearcutting, a terrestrial disturbance recognized as a major threat to biological diversity andExpand
Assessing marine debris in deep seafloor habitats off California.
The first quantitative assessment of debris on the seafloor in submarine canyons and the continental shelf off California, using the Delta submersible, finds plastic was the most abundant material and will likely persist for centuries. Expand
Potential impacts of deep-sea trawling on the benthic ecosystem along the Northern European continental margin: a review
Little is known of the sensitivities of deep seabed communities to anthropogenic disturbance. We collate and summarize the sparse data related to effects on the seabed of deep-sea trawling andExpand

It is shown that species richness of invertebrates and crustaceans, as well as abundance and biomass of crustacean is higher in areas with large stands of the coral, particularly the red shrimps Aristeus antennatus (Risso, 1816) and Plesionika martia (A. Milne Edwards, 1883). Expand
Photographic evaluation of the impacts of bottom fishing on benthic epifauna
The gravel sediment habitat on the northern edge of Georges Bank (East coast of North America) is an important nursery area for juvenile fish, and the site of a productive scallop fishery. During twoExpand
Fishing effects on diversity, size and community structure of the benthic invertebrate and fish megafauna on the Bay of Biscay coast of France
It is concluded that the differences between the most strongly exploited and the moderately exploited areas were consistent with the hypothesis that fishing causes major disturbance to benthic communities on deeper bottoms of the continental shelf. Expand
In situ observations of fish associated with coral reefs off Ireland
Abstract The abundance and behaviour of fish on and around coral reefs at Twin Mounds and Giant Mounds, carbonate mounds located on the continental shelf off Ireland (600–1100 m), were studied usingExpand
