“…Its presence in this 'benthic' group confirms observations by Ross & Quattrini (2007) (29) mysids and teleosts ( blennoides in the first group seems to be due to its feeding on epibenthic species, mostly decapods, mysids and teleosts (Morte et al 2002). However, P. blennoides was observed displaying station-holding behaviour slightly above the bottom in the Bay of Biscay (Uiblein et al 2003).…”

Using a towed camera system, a total of 422 individuals belonging to 62 taxa (including 33 identified species) were counted in the Santa Maria di Leuca (SML) coral province (Mediterranean Sea). Our findings update the knowledge of the biodiversity of this area and of the depth records of several species. The presence of coral mounds mostly in the north-eastern sector of the SML coral province seems to influence the large scale distribution of the deep-sea benthopelagic fauna, playing the role of attraction-refuge with respect to the barren muddy bottoms where fishing occurs in northern areas. Multiple Correspondence Analysis identified 3 main taxa groups: (1) rather strictly linked to the bottom, resting or moving on the seabed, often sheltering and feeding; (2) mostly swimming in the water column and mostly observed on rugged bottoms; and (3) actively swimming or hovering near the seabed. The behavioural patterns largely related to activity and position of the fauna seem to determine their small-scale distribution. The effects of different benthic macrohabitats appear to be less important and the depth within the bathymetric range examined even less so. The behavioural patterns reflect aspects of the species life strategies, revealing common features in phylogenetically and ecologically distant species. The teleost Helicolenus dactylopterus exhibited a clear behavioural pattern of resting on the seabed in different macrohabitats. The golden shrimp Plesionika martia and the fish Pagellus bogaraveo seem to be associated with the presence of corals.

“…As diet is the main source of contamination for fishes (Hall et al, 1997), understanding what food source fuels deep-sea organisms is crucial to better understand their contamination patterns. Some early papers performed extensive studies of the diet of some teleosts and shark species (eg Carrassón et al, 1992;Macpherson, 1979;1981;Morte et al, 2002) whereas more recent research characterized the OM reaching deep zones (Canals et al, 2006;Heussner et al, 2006;Pasqual et al, 2013;Sanchez-Vidal et al, 2013).…”

Mercury (Hg) is a global threat for marine ecosystems, especially within the Mediterranean Sea. The concern is higher for deep-sea organisms, as the Hg concentration in their tissues is commonly high. To assess the influence of food supply at two trophic levels, total Hg concentrations and carbon and nitrogen stable isotope ratios were determined in 7 species (4 teleosts, 2 sharks, and 1 crustacean) sampled on the upper part of the continental slope of the Gulf of Lions (Northwestern Mediterranean Sea), at depths between 284 and 816 m. Mean Hg concentrations ranged from 1.30±0.61 to 7.13±7.09 μg g(-1) dry mass, with maximum values observed for small-spotted catshark Scyliorhinus canicula. For all species except blue whiting Micromesistius poutassou, Hg concentrations were above the health safety limits for human consumption defined by the European Commission, with a variable proportion of the individuals exceeding limits (from 23% for the Norway lobster Nephrops norvegicus to 82% for the blackbelly rosefish Helicolenus dactylopterus). Measured concentrations increased with increasing trophic levels. Carbon isotopic ratios measured for these organisms demonstrated that settling phytoplanktonic organic matter is not only the main source fueling trophic webs but also the carrier of Hg to this habitat. Inter- and intraspecific variations of Hg concentrations revealed the importance of feeding patterns in Hg bioaccumulation. In addition, biological parameters, such as growth rate or bathymetric range explain the observed contamination trends.

“…Three fish (blackbelly rosefish Helicolenus dactylopterus, four-spot megrim Lepidorhombus boscii, and greater forkbeard Phycis blennoides) and two shark species (black-mouthed dogfish Galeus melastomus and lesser spotted dogfish Scyliorhinus canicula) were targeted on the basis of their similar high trophic position, their abundance and their importance in slope and canyons community functioning (Carrassón and Cartes, 2002;Morte et al, 2002;Fanelli et al, 2013;Goujard et al, 2013;Papiol et al, 2013;Tecchio et al, 2013;Fabri et al, 2014;Cresson et al, 2014).In addition, there is a great concern for the chemical contamination in deep-living fish species, the biological and ecological specificities of which, e.g. longer lifespan or reduced growth rate, made them at risk for chemical contamination, as confirmed by high values recorded in those species previously al., 2014).…”

“…Earlier analyses of stomach contents revealed that carnivory is the prevalent feeding behavior in this deep ecosystem, even if a wide range of prey can be consumed, from benthic invertebrates to fish (e.g. Macpherson, 1981;Carrassón and Cartes, 2002;Morte et al, 2002). The recent generalized use of C and N stable isotopes allow an integrated view of the food web organization, tracking organic matter fluxes all along the whole trophic webs (e. g. Polunin et al, 2001;Fanelli et al, 2013).…”

Despite being generally located far from contamination sources, deep marine ecosystems are impacted by chemicals like PCB. The PCB contamination in five fish and shark species collected in the continental slope of the Gulf of Lions (NW Mediterranean Sea) was measured, with a special focus on intra- and interspecific variability and on the driving factors. Significant differences occurred between species. Higher values were measured in Scyliorhinus canicula, Galeus melastomus and Helicolenus dactylopterus and lower values in Phycis blennoides and Lepidorhombus boscii. These differences might be explained by specific abilities to accumulate and eliminate contaminant, mostly through cytochrome P450 pathway. Interindividual variation was also high and no correlation was observed between contamination and length, age or trophic level. Despite its major importance, actual bioaccumulation of PCB in deep fish is not as documented as in other marine ecosystems, calling for a better assessment of the factors driving individual bioaccumulation mechanisms and originating high variability in PCB contamination.
