Última Atlas des invertébrés du Golfe de Gascogne inventoriés dans les captures des chaluts. Campagnes RESSGASC 1992-1995 et EVHOE 1995 ArchiMer Paulmier, Gerard. Numerous invertebrates were collected during various scientific trawling surveys carried out in the Bay of Biscay (RESSGASC, EVHOE), and the adjacent areas between 1993 and 1995. The species captured by the same trawling methods used by professional fishermen represent only a fraction of the known invertebrate fauna in the Bay. In addition to an inventory of the species, a simple key allows easy access to faunistic groups. The species, some of which are economically interesting, form the subject of a short description and, for the most part, a colour illustration.

ArchiMer Gaudin, Mathieu. Submarine canyons cutting continental shelves and slopes are considered to be erosive features allowing continental derived sediment to reach the deep sea. In order to better understand their sedimentary dynamic and morphologic evolution through time, two submarine canyons, the Bourcart canyon in the Gulf of Lion and the Capbreton canyon in the Bay of Biscay have been studied. The Bourcart canyon, located at the shelf break at 110 m water depth, is disconnected from direct sediment supply during sea-level highstand and is considered as inactive. The Capbreton canyon's head is located 400 m off the coastline, and is disconnected from the Adour river since the 16th century. Bathymetric, core, radioisotopic and current data showed that these canyons are...

Nous avons eu l'occasion, dans une note présentée au Comité des poissons démersaux (Sud), de fournir des données préliminaires sur la croissance de la dorade, Pagellus centrodontus. Au cours de l'année écoulée, nous avons d'une part corrigé certains défauts qui présentait ce travail, d'autre part augmenté le nombre de nos observations, particulièrement sur les poissons de grande taille.

The fishery for benthic species (Monkfish, Megrim, Rays, etc ... ) represents for the surrounder countries of the Celtic Sea and the Bay of Biscaye one of the most important activities . An estimate of the discards of the main species resulting from the sorting practice onboard of the trawlers participating in this fishery was made in 1985 and 1991. it was concluded that an important quantity of juveniles of Rays, Megrim and Monkfish are discarded each year causing an important mortality. The aim of the present paper is to present the preliminary results of a selectivity grid fixed on a bottom trawl to limit as possible the discards. Three different grids were tested at sea during surveys with different results. The major problem is due to difference in...

The western Atlantic continental margin of the Bay of Biscay is characterised by a combined macro-tidal and a high energy environment. These conditions are responsible for the essentially sandy sedimentary cover along with well-defined fine deposit zones observed on the shelf. The main continental sources are the Loire, Gironde and Adour Rivers. It is estimated that 2.4 to 2.5 million tons of fine sediments are supplied annually to the ocean from these rivers of the French Atlantic coast. The Gironde and the Loire contribute with 84 % and the Gironde with 60 % of this amount. Previous studies of the distribution of the clay mineral assemblages and of oligo-elements have distinguished two provinces (north and south Biscay areas) according to these riverine...

An acoustic survey was carried out in the bay of Biscay from May 1st to May 30th on board the French research vessel Thalassa. The objective of PELGAS06 survey was to study the abundance and distribution of pelagic fish in the Bay of Biscay. The target species were mainly anchovy and sardine and were considered in a multi-specific context. The results have to be used during ICES working groups in charge of the assessment of sardine, anchovy, mackerel and horse mackerel and in the frame of the Ifremer fisheries ecology program "resources variability" Tipo: Text Palavras-chave: Bay of Biscay; Plakton net; Trawl; CUFES; Survey; Acoustic; ICES; PELGAS; Anchovy; Golfe de Gascogne; Filet à plancton; Chalut; CUFES; Campagne; Acoustique; CIEM; PELGAS; Anchois.

Depuis une vingtaine d'années, l'Ifremer organise des campagnes de pêche scientifique en mer du Nord, Manche, Atlantique et Méditerranée concernant les ressources pélagiques, démersales et benthiques. L'objectif prioritaire est de produire des indices d'abondance des principales espèces commerciales. Elles recueillent également des données sur les espèces capturées non commerciales. Les campagnes sont réalisées selon des plans d'échantillonnage standardisés. L'engin de pêche et son gréement, la position des stations, le tri des captures, les prélèvements biologiques suivent des protocoles fixés. Chaque zone étudiée est découpée en fonction de la profondeur, de la latitude ou d'autres critères. L'échantillonnage prévoit un nombre de traits de chalut...

Fisheries acoustic data are continuously collected during ecosystemic surveys to detect sh schools of commercial species and to quantify the sh abundance. These multifrequency data also contain information about smaller target aggregations producing ubiquitous Sound Scat- tering Layers (SSLs) on the echograms, with quite diverse shape, frequency responses and taxonomic compositions. In this work, we focus on the SSLs observed in spring in the Bay of Biscay during the PELGAS surveys. The objectives are: i) to classify SSLs, ii) to describe their spatial meso-scale distribution, iii) to investigate their relationships with oher exosystme components, and iv) to investigate the taxonomic composition of resonant SSLs at ne scale.

A two years ichthyoplankton sampling program over an eight station network on each side of a coastal tidal front was conducted twice a month during neap tides. A principal component analysis was performed on the data (taxa and observations) which were segregated during the summer into two groups of taxa related to two groups of stations belonging to two different hydrodynamical areas. In July and August 1980 during a tide cycle, zooplankton was investigated at two stations in the stratified and transitional area. Periodic fluctuations of meroplanktonic taxa correlated to the movement of the front induced by the tide were observed.

Coccoliths, in cells or detached, from coccolithophores are calcite plates with highly backscattering signal.Coccolithophore blooms are visible from space and are currently quantified by Calcite algorithm fromNASA applied to Ocean Color data. Coccoliths impact also the Suspended Particulate Matters (SPM) product from Ifremer, well established in the Northwest european continental shelf. Although these algorithms are independent, they are based on the same basic concepts, but Ifremer algorithm is more adaptable and allows to link up with other particles than coccoliths, as the resuspended matters or aggregates.Coccolithophore blooms identification over 18 years, from bay of Biscay to South Irelands has been established by a spectral method, allowing to...

La campagne PELGAS participe à la gestion du stock d’anchois du Golfe de Gascogne, en réalisant une évaluation directe à la mer de la biomasse d’anchois. Pour déterminer la biomasse totale, des appareils acoustiques envoyant des ultra-sons dans l’eau pour détecter les bancs de poisson sont utilisés. Ensuite des pêches sont effectuées sur les zones détectées pour déterminer la composition des bancs (espèces, poids, longueurs…). En parallèle, les oeufs d’anchois sont comptés. A partir des données récoltées de 2000 à 2015, j’ai pu réaliser des cartes de distribution spatiale des anchois et de leurs oeufs, ainsi que des analyses statistiques afin de comprendre les différences de distribution entre les deux.
