In contrast to generally sparse biological communities in open-ocean settings, seamounts and ridges are perceived as areas of elevated productivity biodiversity capable supporting commercial fisheries. We investigated the origin this apparent enhancement over a segment North Mid-Atlantic Ridge (MAR) using sonar, corers, trawls, traps, remotely operated vehicle survey habitat, biomass, biodiversity. Satellite remote sensing provided information on flow patterns, thermal fronts, primary...
Abstract Sustainable exploitation of marine populations is a challenging task relying on information about their current and past abundance. Fisheries‐related data can be scarce unreliable making them unsuitable for quantitative modelling. One fishery independent method that has attracted attention in this context consists estimating the effective population size ( N e ), concept founded genetics. We reviewed recent empirical studies carried out simulation study to evaluate feasibility large...
Abstract Effective population size ( N e ) is a key parameter of genetics. However, remains challenging to estimate for natural populations as several factors are likely bias estimates. These include sampling design, sequencing method, and data filtering. One issue inherent the restriction site‐associated DNA (RADseq) protocol missing SNP selection criteria (e.g., minimum minor allele frequency, number SNPs). To evaluate potential impact on estimates (Linkage Disequilibrium method) we used...
The deep-sea environment is a sink for wide variety of contaminants including heavy metals and organic compounds anthropogenic origin. Life history traits many deep-water fish species longevity high trophic position may predispose them to contaminant exposure subsequent induction pathological changes, tumour formation. lack evidence this hypothesis prompted investigation in order provide data on the presence changes liver gonads several species. Fish were obtained from north east region Bay...
Abstract We present practical lessons learned from applying the recent close-kin mark–recapture (CKMR) abundance estimation method to thornback ray (Raja clavata). For CKMR, related individuals are identified their genotypes and number pattern is used for estimation. genotyped over 7000 collected in Bay of Biscay using Single Nucleotide Polymorphism (SNP) markers finding 99 parent–offspring pairs. The estimated adult rays central was around 135000 (CV 0.19) 2013. In total, four were drawn:...
Fishery catch data offer a rich potential source of information for management, if modelling can separate out the effects fishing effort, species behaviour and population abundance. Here, we model from blue ling fishery off northwest coast Scotland, using generalised additive mixed models with space time interaction represented via novel tensor product soap film smooth penalized regression spline time. The use smoothers avoids imposing correspondences between spatially adjacent areas that...
Abstract This study assesses the impact species ecology, fish reactions, and natural behaviour have on visual strip transect counts of deepwater carried out with an ROV (remotely operated vehicle). Two terraces one canyon were visited continental slope Bay Biscay. Species such as rabbit (Chimaeridae) North Atlantic codling (Lepidion eques) appear to avoided ROV. The vertical distance off bottom provided evidence that some individuals, in particular slickheads (Alepocephalidae) might been...

Prey preferences of adult sea bass Dicentrarchus labrax in the northeastern Atlantic: implications for bycatch common dolphin Delphinus delphis – ICES Journal Marine Science, 70: 452–461. In Atlantic, (Dicentrarchus labrax) is one largest fish living on shelf, this species has important commercial value. However, pelagic trawl fisheries that target have negative operational interactions with dolphins...
Abstract Environmental DNA (eDNA) metabarcoding is a method to detect taxa from environmental samples. It increasingly used for marine biodiversity surveys. As it only requires water collection, eDNA less invasive than scientific trawling and might be more cost effective. Here, we analysed data both sampling methods applied in the same survey targeting Northeast Atlantic fish Bay of Biscay. We compared regarding distribution taxonomic, phylogenetic, functional diversity. found that captured...
The ecosystem-based approach to fisheries management and, more specifically, the European Marine Strategy Framework Directive require assessment of state and dynamics an ecosystem in order determine suitable strategies. This paper takes analytical assess Bay Biscay early 1990s, chosen as a period reference because key monitoring data series have been collected since then. To ecosystem, pressures exerted by six broad categories human activities were examined. A literature review components...
