Atlas des invertébrés du Golfe de Gascogne inventoriés dans les captures des chaluts. Campagnes RESSGASC 1992-1995 et EVHOE 1995
Provedor de dados: 5
Autores: 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.

Processus et enregistrements sédimentaires dans les canyons sous-marins Bourcart et de Capbreton durant le dernier cycle climatique.
Provedor de dados: 5
Autores: 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...

Preliminary results of a trawl fitted with a selective grid for the fishery of benthic species from Celtic Sea and Bay of Biscay
Provedor de dados: 5
Autores: Meillat, Marc; Dupouy, Herve; Bavouzet, Gerard; Kergoat, B.; Morandeau, Fabien; Gaudou, Olivier; Vacherot, Jean-philippe.
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...

Pb, Zn, Cs, Sc and rare earth elements as tracers of the Loire and Gironde particles on the Biscay shelf (SW France)
Provedor de dados: 5
Autores: Jouanneau, Jm; Weber, O; Grousset, Fe; Thomas, B.
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"

Autores: Remond, Barbara.
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.

Fluctuations d'abondance de l'ichtyoplancton sur une zone frontale cotiere (Golfe de Gascogne: Baie d'Audierne)
Provedor de dados: 5
Autores: Camus, Patrick; Delpech, Jean-paul; Omnes, Marie-helene; Mastail, Max.
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.

Autores: Perrot, Laurie.
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...

Compréhension des différences de distribution spatiale des anchois et de leurs œufs
Provedor de dados: 5
Autores: Godet, Claire.
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. Il s’avère que les oeufs sont plus au large que les...

Les déterminants de la trajectoire économique d'une pêcherie complexe : cas de la pêche française dans le golfe de Gascogne
Provedor de dados: 5
Autores: Steinmetz, Fabien.
The average trophic level of the landings of the species landed by the french fleets in the Bay of Biscay is dropping since 30 years, according to the worldwide range observations of Daniel Pauly. The effects of the ecosystemic, institutional and economic factors of this drop are studied with two complementary approaches, a time series analysis and the interpretation of the phenomenons thanks to a bio-economic model. The major factors which could interact with the exploitation from 1973 to nowadays have been analysed. The short term study of the productions and the productivity of tree large trawler fleets from south brittany showed that they adapted according to their specificities to the constraints enforced by the stocks or the prices. At the larger...

La dynamique des pêches côtières du pays bigouden
Provedor de dados: 5
Autores: Charuau, Anatole.
In the beginning, the coastal fleet of the Bigouden region fished by trawling and was completely focused on exploiting lobster and hake. It is a traditional business that expanded between the last war and the 70s, reaching its peak between 1975 and 1980.  The best image to give an idea of this fleet is that of a "bucket waterwheel" endlessly discharging its catch in the four ports of the Guilvinec district. Where there is a seafaring business in Guilvinec, Loctudy and Saint-Guénolé, there is a complementarity that is expressed in two ways: - coastal fishing constitutes a very noticeable and regular supplement to production, since sales happen daily and only bad winter weather causes a relative decrease in the supplement. - coastal fishing gives a...

Autores: Gros, Philippe.
A population of the burrowing goby Lesueurigobius friesii was studied from 1974 to 1979, at a sampling station located on a Nephrops ground in the northem Bay of Biscay, off the south coast ofBrittany; samples were collected close to a muddy bottom, at depths ranging from 80 to 100 m. Data on demographie structures were obtained by two independent exercises: examination of oto1iths and the analysis of length-frequency distributions. The fish attains a standard length of at !east 71 mm and an age of 6 years. Most growth takes place during the first three years of !ife, and proceeds very slowly thereafter. The state of gonad development was assessed qualitatively by visual inspection of the body cavity of females; spawning occurs in spring, and by July 61 of...

This work aims to summarize the work carried out in the framework of surveys in subtidal environment on the French Basque coast in 2017. The course of this campaign is presented as well as the various data collected making it possible to establish a balance sheet. The latter refers to the fact that only one of the three targeted steps could be correctly sampled from a biological and ecological point of view. The analysis of the difficulties encountered during these investigations will make it possible to reframe the implementation of the protocol in order to best meet the objectives originally set during the 2018 sampling program.

Apports des données de la 'couleur de l'eau' à la modélisation couplée physique-biogéochimie en milieu dynamique côtier : Application au Rio de la Plata et au Golfe de Gascogne
Provedor de dados: 5
Autores: Huret, Martin.
Continental margins play a crucial role in biogeochemical fluxes between the continents and the open ocean. They are also highly sensitive to human perturbations. Primary production is highly dependent on the complex dynamics of these coastal zones, and on the river supply in nutrients, as well as in Suspended Particulate Matter (SPM) which limit light availability. The quantification of the production is a prerequisite in many applications, from the understanding of the role of the coastal ocean in climate change, to eutrophication and fisheries resources issues within the frame of the integrated management of the coastal zone.

In 2005, a flying fish Cheilopogon cyanopterus, which doesn't figure among the Europeans faunas although pointed out in 1973, is captured in the Bay of Biscay. Following the catch of a Cubiceps gracilis near the coast in Britain, the authors recapitulating the former descriptions indicate that adults of this oceanic species remain in the open sea. Only juveniles come, rarely, to the coast. The species figures in the diet of common dolphins, striped dolphins, swordfishes and tunas. NOT CONTROLLED OCR

The aim of the project "rationalization of biological sampling for stock assessment of marine fisheries in the bay of Biscay" is to perform statistical methods and computer programs allowing to test prognoses and diagnoses based on estimates of fishing mortalities, recruitments, yields per recruit, and the "gain-loss" function. The project gathers the laboratories of the community working on the Bay of Biscay fisheries, namely - Santander in Spain (1. E. 0) - La Rochelle and Lorient in France (IFREMER). A descriptive study has been carried out. The prepared documents contain a description of the procedures used to collect the information, by each of the laboratories involved, on: - landings - biological samplings. More comprehensive data have been gathered...

Les pêcheries mixtes de langoustine et merlu du Golfe de Gascogne, modélisation bio-économique et simulation des procédures de gestion
Provedor de dados: 5
Autores: Charuau, Anatole.
Fishing crayfish on the gulf's mudflats is a traditional business practised by 450 boats of 12 to 18 metres in length and employs 2,500 sailors. In the north of the gulf, this activity is exclusive, in the south, immature hake are also caught, because the crayfish areas coincide, in part, with the nurseries of the northern stock of this species.   Management of these fisheries, called mixed, of crayfish and hake is one of the greatest problems of the Gulf of Gascony. All assessments tend to show the responsibility of the crayfish boats in the future of the hake stock. The solution is likely to pass through a generalised increase of the 80 mm meshing that would lead, eventually, the hake stock yield to its maximum, but would eliminate a great many trades...

The French anchovy fishery
Provedor de dados: 5
Autores: Duhamel, Erwan; Biseau, Alain; Masse, Jacques; Villalobos, Hector.
The french fishery of anchovy is divided in two groups defined by gears : purse seine and pelagic trawl. The average length of these vessels is about 20m. This fleet is very opportunistic : all trawlers are using several trawls during the year, to catch sometimes bass, tuna, hake, or scampi, and purse seine are mainly fishing sardine. Each year, the main anchovy catches are provided by pair trawlers. Purse seiners operate often in coastal areas (&lt;10 nautical miles); trawlers may operate until 50 nautical miles offshore but are banned inside the three miles coastal zone. The pair trawlers may operate from Basque country to western Channel according to fish availability. Purse seiners usually stay around their home harbour.

3D modelling of seasonal evolution of Loire and Gironde plumes on Biscay Bay continental shelf
Provedor de dados: 5
Autores: Lazure, Pascal; Jegou, Anne-marie.
A 3D model of the Atlantic shelf has been developed and applied to study shelf dynamics and evolution of hydrology. The model takes the combined effects of tide, wind, river discharges and surface heat flux into account. Time scales vary from 1 day to several years. Following a brief description of the model and forcing variables, the behaviour of the Loire and Gironde plumes is described, first for winter and spring, then over a period of several years, under realistic forcing. The results show that plume evolution depends on the high Variability of river runoff and winds. Model simulations performed over 7 years (1990 to 1996) have highlighted several features of these plumes: 1) In early winter and periods of high river runoff, plumes usually spread...

French potters from « Manche ouest » harbours ish edible crab Cancer pagurus in English Channel, Iroise Sea and along north Biscay Bay shelf. Monthly landings of the offshore fleet analysed from logbooks for the period 1985-1987 indicate changes in fishing areas. The mean length of males, the mean length of females and the sex-ratio have been analysed by Principal Component Analysis in 1981-1987 samples. The heterogeneity between catches from different statistical rectangle (30 x 40 nautical miles) was great enough to deduce a way of raising composition from samples to total landings. It also offers the possibility to verifiy and correct declaration on geographical origin of landings.

The ecosystems exploited by fishing are complex. The species which are sought after and their distribution rely on numerous processes, in time and space. The understanding of marine ecosystems requires important means and diverse information including those of professional fishing and scientific cruises. At first, scientific fishing cruises aimed to explore marine fauna and discover new halieutic resources. They were in line with the exploration cruises carried out by Prince Albert 1st of Monaco at the end of the XIXth century. However, since the beginning of the 1970s, they have been focusing on the quantification of the resources exploited by fishing.

The landing obligation implemented under the Common Fisheries Policy promoted the development of fishing gear selective devices. The REDRESSE project conducted in the Bay of Biscay was the opportunity for trawl fleets targeting cephalopods, Nephrops and demersal fish to continue to test various selective configurations to reduce their discards levels. The sea trials were carried out onboard of commercial fishing vessels and the experimental tows were sampled by an observer. Most of the selective devices were tested under the twin trawl method, with on one side the gear to be tested and on the other, the standard commercial gear. Other devices were tested with the parallel or alternate haul method. The data obtained were used to describe the catch species...

Facteurs de mortalité observés chez les tortues marines dans le golfe de Gascogne
Provedor de dados: 5
Autores: Duguy, R; Moriniere, P; Le Milinaire, C.
Factors of mortality in marine turtles near the French coast of the Bay of Biscay have been recorded for four species: leatherback (Dermochelys coriacea), loggerhead (Caretta caretta), Ridley's turtle (Lepidochelys kempii) and green turtle (Chelonia mydas). Most accidental captures of D. coriacea by fishing gears lead to drowning, but the main threat for the species is the ingestion of floating waste. Plastic bags induce occlusion or lesions in the stomach and subsequent death. For C. caretta, L. kempii and C. mydas, the pathology points out mainly two features: external or internal mycosis.

Effets combinés des facteurs naturels et anthropiques sur les communautés d'invertébrés benthiques des vasières à langoustines (Nephrops Norvegicus) du golfe de Gascogne
Provedor de dados: 5
Autores: Robert, Alexandre.
Bottom trawling is a widespread fishing activity that covers most of the North-European continental shelves. This activity is likely to alter the benthic habitats, the structure and biodiversity of benthic communities as well as the ecosystem functioning. However, bottom trawling effects vary according to the habitats and, specifically according to the magnitude of the natural sources of disruptions. Consequently, it is difficult to predict the effects of the fishing activity. So, a specific investigation has to be conducted in each fishery in order to characterize the effect of bottom trawling. The Bay of Biscay (BoB) is fished for Norway lobsters and hake. Bottom trawling is one of the most important fishing activities, both economically and regarding to...

Autores: Latrouite, Daniel; Leglise, Michel; Raguenes, Gérard.
This paper deals with the lobsters caught by French fishermen off the "Conquet" (Iroise sea) and off "Ile d'Yeu" (Biscay Bay) on the French atlantic coast. The size at first maturity, defined as the size at which 50 % of female are able to reproduce, is deduced from the analysis of size frequency in landings. It is also shown that more than 50 % of the mature female are spawing each year ; the periods of hatching in the natural environment are also established.

The European contract PECOSUDE (Small inshore fisheries of the south of Europe) accepted in 2000 (n° 99/024) for 2 years involves French partners (IFREMER, GEOLITTOMER and CEMAGREF), Spanish (AZTI, UPV and IEO) and Portuguese (IPIMAR). The aim is to assess the inshore and estuarian fisheries from Loire estuary to Portugal in view of the negotiations of the PCP in 2002. Three main aspects are considered in the study: fisheries monitoring (data 1999), socio-economy and marketing (data 1999 or 2000). Three main criteria have been established to define the limits of the fishing fleet considered in the study : fishing grounds within the 12 miles zone for the French fleet and the continental shelf and slope (down to 1000 m depth) for northern Spanish and...

The boundary circulation along the European continental slope as transport vehicle for two calanid copepods in the Bay of Biscay
Provedor de dados: 5
Autores: John, Hc; Mittelstaedt, E; Schulz, K.
The copepod fauna south-west of the British Isles includes a number of species which have their centre of distribution in the subtropical or tropical Atlantic. Among these, some species appear to be faunistically linked with the Iberian continental slope or slope waters even farther south along the NE Atlantic margin. It seems that these species reach their north-eastern range by means of poleward-flowing currents. For example, Calanoides carinatus has deep-living resting stages and ascends to surface waters only during its reproductive period, which is short at northern latitudes. Its main dwelling layers along the west Iberian continental slope cover the poleward-flowing undercurrent and the Mediterranean outflow water underneath. Part of the poleward...

L'anchois du golfe de Gascogne - Généralités et campagne de pêche en 1993
Provedor de dados: 5
Autores: Prouzet, Patrick; Metuzals, K.
The anchovy, Engraulis encrasicolus L. population in the Bay of Biscay, is described in context with other Engraulidae populations in the world. Mean landings are provided for six different species from 1974 to 1992. The great variations in the abundance (up to 200 %) of these populations, in relation to upwelling and environmental parameters are also discussed. Historical changes in the French and Spanish fleet fishing for anchovy are highlighted since 1950. The main events in the development of these fisheries are detailed. The total number ofboats in the French fleet have increased from 1987-1993 whereas the number of seiners in the Spanish fleet in that peri ad remained stable since 1980. The third part of this report describes the French fishery for...

Seasonal and inter-annual variability in properties of surface water off Santander, Bay of Biscay, 1991-1995
Provedor de dados: 5
Autores: Lavin, A; Valdes, L; Gil, J; Moral, M.
The annual cycle of temperature, salinity and nutrients of surface waters (up to 100 m depth) was studied from June 1991 to December 1995 in a cross-shelf section over the continental shelf waters off Santander (southern Bay of Biscay). The time series showed that the temperature followed the expected seasonal warming and cooling pattern, which determines a seasonal process of stratification and mixing of the water column. The stratification period occurs annually between May and October in a layer of about 50 m depth from the neritic station beyond to the shelf-break. In the period between November and April the water column remained mixed. During spring and summer low salinity values were found in the surface due to continental runoff and advection from...

Autores: Labry, Claire.
This study was supported by the Atlantic working site of the « Programme National d’Océanographie Côtière » (PNOC, PNEC since 1999). The objectives were (1) to check the existence and to understand the mechanisms of winter phytoplankton blooms in the bay of Biscay influenced by the Gironde waters (2) to determine the limiting nutrient of the primary production associated to these blooms and to follow the seasonal evolution of the limiting nutrient, (3) to understand the consequences of this early limitation on the structuration of algal populations in spring. Since phosphorus was supposed to be the major limiting nutrient of algal growth in the Gironde plume, the different forms of the phosphorus cycle as well as the bacterial compartment, central in this...

Afler a short review of acoustic principles, methodology and purposes of accustic surveys are described and some examples given. IFREMER instrumentation, strategy and calculations used during echo sur veys are  described in details and criticized. Five acouslic sur veys carried o t in the Bay of Biscay between 1983 and 1987 show that several species are generally mixed , and lheir identification is very oflen biased by behaviour phenomena. A new way of classi fying echotraces and interpretating data has been applied to these surveys. The results are summarized in tables and maps. Whenever multispecies structures are concerned, it seems at present impossible to assess absolute biomasses based on acoustic survey method. ln such a situation, acoustic surveys...

Diversité phénotypique dans la population d’anchois commun (Engraulis encrasicolus) du golfe de Gascogne
Provedor de dados: 5
Autores: Leseur, Floriane.
With the constant rising of the human population, it is essential to assess and manage the exploitation of the marine species for human consumption such as the anchovy of Bay of Biscay. Thanks to the PELGAS annual surveys, stocks of each species are estimated (biomass, repartition) and studies are undertaken to improve our knowledge about these species. Allozymic studies realized on the anchovy allowed to find a correlation between 2 alleles of the locus IDH and the habitat (depth). This allozyme has a key role in Krebs’ cycle,being speed limiting.. It enables to tolerate variations of temperature and dissolved oxygen. It would be interesting to do new research on variations in the anchovy’s environment and its migrations.

Étude par acoustique large bande de la composition et de la distribution spatiale de couches diffusantes denses dans le golfe de Gascogne
Provedor de dados: 5
Autores: Blanluet, Arthur.
Intermediate trophic components of pelagic ecosystem (from mesozooplakton to micronekton) funnel energy and organic matters from primary producers to many commercial species (anchovy, sardines…). Some of these organisms are supposed to be important contributors to the ubiquitous Sound Scattering Layers (SSLs) observed over a broad range of spatio-temporal scales and geographical areas. Yet, the SSLs taxonomic composition remains largely unknown. The aim of this PhD was to describe the composition and repartition of dense SSLs observed in the Bay of Biscay (France) in spring at several spatial scales, using broadband acoustics, nets and videos. In the first chapter, we showed that the echo sounder beam widths had few effect on the SSLs backscatter,...

Déclin de la taille-aux-âges des sardines (Sardina pilchardus) : diminution de la croissance et/ou disparition sélective des individus à croissance rapide
Provedor de dados: 5
Autores: Gentil, Claire.
In many exploited species, we see a decrease of size-at-ages. Two main hypotheses have been proposed to explain this decline: a decline in growth and the selective mortality of the individuals with fast growth both being due to environmental changes or/and to fishing. The sardine Sardina pilchardus of the Bay of Biscay is a good model for the study of this phenomenon because of its high sensitivity to the environmental variations and it sustains two large French and Spanish fisheries. The aim of this study is to measure the changes in the growth of sardines, by the reading of otoliths, and to understand mechanisms involved in this process. The main stages of this study are described in this report: extraction of otoliths during PELGAS, otoliths...

The stocks of whiting (Merlangius merlangus), pollack (Pollachius pollachius) and striped red mullet (Mullus surmuletus), are considered by ICES as Data Limited Stocks (DLS) for the Bay of Biscay areas, those bordering the Iberian Peninsula as well as the Celtic Sea for red mullet. In the case of insufficient data for an analytical assessment, ICES has recommended, for 2013 and 2014, to precautionarily reduce landings by 20 % compared to the period 2009-2011 for these 3 stocks. In order to improve knowledge to fill the gaps in the status of these stocks, and to extract them from the DLS category, the ROMELIGO project has: i) analyzed available data on both catches and professional fishing activity, Captures per Unit of Effort (CPUE) to identify reference...

Le projet FFP Captain visait à l’amélioration des connaissances biologiques et sur la connectivité des stocks de sardine et d’anchois sur la façade Atlantique française (Manche et golfe de Gascogne). Il a reposé sur la collecte de données au travers d’une collaboration avec les professionnels de la pêche (organisations de producteurs et pêcheurs) et de l’exploitation opportuniste des pêches sur l’ensemble des campagnes halieutiques de la zone (PELGAS, EVHOE, CGFS). Ceci a permis une couverture spatiale et saisonnière optimale. Nous avons ainsi affiné la description spatio-temporelle de la reproduction pour les deux espèces, et montré une plus forte croissance ainsi qu’une densité énergétique plus élevées en Manche que dans le golfe de Gascogne.

La ponte de la sardine en 1964 dans le golfe de Gascogne et sur le plateau celtique a été récemment étudiée à l'Institut des Pêches par S. Arbault et N. Boutin dans le cadre d'une travail plus général sur la répartition saisonnière des oeufs et larves de téléostéens, travail que résume une communication présentée au Comité du plancton. Les résultats exposés ici et limités à la seule sardine, font suite à l'étude des ces chercheurs et proviennent du dépouillement des pêches planctoniques de 3 campagnes d'hydrologie des pêches effectuées par la Thalassa et la Pélagia dans la même région du 26 avril au 9 mai 1966, du 13 février au 22 mars 1967 et du 16 mai au 7 juin 1967.

Développement d'une plateforme d'évaluation de plans de gestion spatialisés : application à la pêcherie mixte démersale du golfe de Gascogne
Provedor de dados: 5
Autores: Vigier, Audric.
North-East Atlantic fisheries management goes towards a regionalisation, accounting for mixed fisheries technical interaction. Hence, understanding and assessing the spatio-temporal dynamics of exploited species and the fleets exploiting them is needed. This study aims to provide a tool to assess the effects of several management scenarii in the Bay of Biscay. lt fouses on North-east Atlantic northern hake stock (Merluccius merluccius) and the mixed demersal hake - sole (Solea solea) - Norway lobster (Nephrops norvegicus) Bay of Biscay fisheries.A Management Strategy Evaluation (MSE) framework has been developed, pairing a spatial northern hake stock assessment model, and an operating model (lSlS-Fish) simulating the Bay of Biscay mixed demersal...

Campagne Techorhago
Provedor de dados: 5
Autores: Vacherot, Jean-philippe.
Pour être en phase avec les recommandations de la communauté européenne, les missions ORHAGO doivent utiliser un chalut à perche pour la constitution des indices d'abondance de sole dans le golfe de Gascogne. Un chalut à perche de 4 m (environ 2000 kg) a été construit et acheté aux Pays-Bas dans l'optique des futures campagnes à la mer. La campagne TECHORHAGO visait à essayer et à mettre au point les différentes manoeuvres de mise à l'eau et de virage du chalut en le remorquant sur les deux treuils du Gwen-Drez. L'EROC (Engin Remorqué d'Observation des Chaluts) était embarqué.

Autores: Leaute, Jean-pierre.
The regular aerial survey over the Bay of Biscay (France) by the French Custom Air Service enabled us to record precisely in 2001 the geographical positions of French fishing vessels inside the 12 nautical miles of the French Bay of Biscay (from Bay of Audierne to Spanish border). Among the 2396 ships counted in this area, 1810 were identified, corresponding actually to 900 boats since most of them (52 %) were seen several times. These 900 boats referred to 4 different "métiers", i.e. type of fishing activity: most of them (59 %) were bottom trawlers, 28 % gillnetters, 5 % potters and 5 % longliners; those which used another gear were less than 4 %. General characteristics of the 900 ships were identified: tonnage and power were respectively 25 TJB and 185...

La croissance de la dorade, Pagellus centrodontus, ne paraît pas avoir fait jusqu'à présent, du moins dans l'Atlantique européen, l'objet de nombreuses recherches et seul Olivier (1928) semble s'être penché sur ce problème. Pour les poissons des côtes marocaines nous connaissons l'étude faite par Coupe dont les résultats ont été présentés au CIEM dn 1954. Le premier ce ces auteurs a examiné un nombre relativement important d'écailles (331) sur lesquelles il n'a procédé qu'à une numération des anneaux. Le second a eu recours à la scalimétrie qui est la méthode habituellement employée pour l'ensemble des sparidés.

Autores: Huret, Martin; Struski, Caroline; Leger, Fabien; Petitgas, Pierre; Lazure, Pascal; Sourisseau, Marc.
Une simulation 'hindcast' de la dynamique physique et biogéochimique du golfe de Gascogne a été réalisée pour la période 1971-2007 à l'aide du modèle ECO-MARS3D. Ce modèle couplant physique et biogéochimie fournit une série longue de données simulées, moyennées ou intégrées sur 3 jours (température, salinité, sels nutritifs, phytoplancton, zooplancton), qui sont ensuite utilisées pour des calculs d'indices hydrologiques 2D synthétiques (indices méso-échelle : stratification, upwellings, surface tourbillonnaire ; indices biologiques : chlorophylle-a de surface, production primaire intégrée). Nous nous proposons dans ce document de présenter la configuration et les forçages utilisés pour cette simulation, et de lister les différentes variables sauvegardées...

This document presents a comparative assessment of six triennal analysis carried out between 1986 and 2002, on 1300 boats, on average, from the 35 ports of Southern Bay of Biscay fishing fleets (from Loire river to Spanish border). Fisheries statistics allow the identification of different fishing practices and fishing boats associated with them within the fleets. In order to allow comparison and analysis of the evolution that has taken place during the study period, the same variables (gears used, landed species) and multivariate analysis procedures have been used to produce groupings of vessels.   Over the period, 11 components, on average, have been identified, grouped in two entities, mobile and fixed gears. If the discriminative characteristics...

Spring microzooplankton composition, biomass and potential grazing in the central Cantabrian coast (southern Bay of Biscay)
Provedor de dados: 5
Autores: Quevedo, M; Anadon, R.
Microzooplankton abundance, biomass and composition were investigated in the coastal waters of Asturias (southern Bay of Biscay) in May 1996. Abundance ranged from 0.7 x 10(3) to 8.5 x 10(3) cell.L-1 The protists community was dominated by aloricate ciliates averaging 82 % of microheterotrophs. Small aloricate ciliates, below 20 mu m in size, contributed 63 % to total ciliate abundance. Carbon biomass ranged from 2.4 to 15.4 mgC.m(-3), averaging 23 % of phytoplankton biomass. Aloricate ciliates were also the dominant component of biomass (56.2 %), but the importance of copepod nauplii increased in terms of carbon, averaging 28.5 % of total biomass. Microzooplankton biomass was significantly correlated with Chi a concentration in the water column....

The European contract PECOSUDE (Small inshore fisheries of the south of Europe) accepted in 2000 for 2 years concerns French, Spanish and Portuguese partners. The aim is to assess the inshore and estuarine fisheries from Loire estuary to Portugal. Three levels of study are considered : fisheries (data 1999), socioeconomy and marketing (data 1999 or 2000). Exploitation in the 12 miles area for France and on continental shelf for northern Spain and Portugal (within 1000 m depth), as well as the fishing period lower than 96 hours was determined as the definition of this fishery for the study. Socioeconomic analyses are made only on boats smaller than 15 m. The fisheries part analyses the activity of the fishing vessels taking into account gears used, landed...

Les dinophycées pélagiques et benthiques du Golfe de Gascogne sud de la Bretagne à Arcachon
Provedor de dados: 5
Autores: Paulmier, Gerard.
Les microphytes planctoniques et benthiques du Golfe de Gascogne sont relativement diversifiés. Cette diversification est probablement en rapport avec la situation hydrologique particulière de cette région enrichie par des mélanges de masses d'eau de diverses origines et par des apports continentaux importants. Dans ce contexte, les dinophycées sont nombreuses et variées et occupent toutes les niches écologiques. 230 taxons ont été répertoriés. Quelques espèces sont connues pour provoquer périodiquement des colorations de la mer "eaux rouges" et quelques-unes sont maintenant redoutées pour leur toxicité.

Essais de marquage sur le merlu dans le golfe de Gascogne
Provedor de dados: 5
Autores: Dardignac, Jean.
Le marquage du merlu est généralement considéré comme une opération difficile et rares sont les succès enregistrés jusqu'à présent (FRITZ 1959, GUILLAND 1959). Les principales difficultés auxquelles se sont heurtés les expérimentateurs sont la fragilité du revêtement écailleux de cette espèce et sa sensibilité à la décompression qui provoque souvent une éversion de l'estomac. Pour ces raisons la technique du marquage n'a jamais été employée à grande échelle sur le merlu pour l'estimation de la mortalité due la pêche. En mai 1968, l'Institut des Pêches a procédé, sur la Thalassa, à une série d'essais sur du matériel capturé au chalut.

Evidence of heavy predation by Noctiluca scintillans on Acartia clausi (Copepoda) eggs off the central Cantabrian coast (NW Spain)
Provedor de dados: 5
Autores: Quevedo, M; Gonzalez-quiros, R; Anadon, R.
A large proliferation of Noctiluca scintillans (Dinophyceae: Noctilucidea) was observed in neritic waters off the central Cantabrian coast during late April 1995. Eggs of Acartia clausi (Crustacea: Copepoda) were the most conspicuous prey within vacuoles of Noctiluca. Noctiluca ingested 73 % of the total stock of A. clausi eggs. This intense predation on copepod eggs could potentially affect the recruitment of nauplii. The potential impact on the stock of Acartia clausi eggs and on the daily egg production of the population is discussed. There is a negative correlation between the average number of ingested eggs by a single Noctiluca cell and the abundance of Noctiluca. This fact, coupled with the lack of significant correlation between the former variable...

Reconstruction des transferts sédimentaires en provenance du système glaciaire de Mer d'Irlande et du paléofleuve Manche au cours des derniers cycles climatiques
Provedor de dados: 5
Autores: Toucanne, Samuel.
The Pleistocene has been period of fluctuating climate accompanied by prominent sea-level lowstands during the glacial intervals, when massive continental ice sheets extended from mountainous to lowland European areas. The retreat of the shoreline on the extensive present-day shallow continental shelf of the southern part of the British Isles induced the appearance of the 'Fleuve Manche' palaeoriver, one of the largest systems that drained the European continent. Sedimentary records from the Bay of Biscay offer an independent record allowing the reconstruction of the freshwater and sediment discharges of the 'Fleuve Manche', and the possibility of detecting the imprint of surrounding ice-sheet oscillations and attendant modification of hinterland drainage...

Évolution de l'écosystème pélagique du Golfe de Gascogne pendant la période 1990-2003. Conséquences sur la capturabilité des espèces
Provedor de dados: 5
Autores: Villalobos, Hector.
Several small pelagic fish species contribute remarkably to world catch. Their populations are, however, characterized by large biomass fluctuations strongly affecting fisheries. The fishing gears and methods used to capture small pelagics have evolved to exploit the highly developed shoaling behavior of these species. Hence, faced to modern fishing this gregarious behavior becomes a disadvantage for fish. Fish behavior may be affected by environmental conditions and by fishing, at the same time that behavior impacts fishing. In this study, we seek to characterize the aggregative systems of small pelagic fishes inhabiting the Bay of Biscay by analyzing "acoustic images", defined as the group of echoes (planktonic layers, shoals, isolated targets) detected...

Biologie et pêche du céteau (Dicologoglossa cuneata Moreau) dans le sud du golfe de Gascogne
Provedor de dados: 5
Autores: Forest, Andre.
Le céteau, Dicologoglossa cuneata (Moreau), est pour les pêches françaises en Atlantique, une espèce d'importance économique très secondaire : il n'apparaît pas dans les statistiques de la Marine Marchande et l'on peut estimer sa production aux environs de 450 ou 500 t par an. Il fait néanmoins l'objet d'une pêche particulière de la part de bon nombre de chalutiers artisans des Sables d'Olonne, de l'Ile d'Yeu, de La Rochelle, de l'Ile d'Oléron et d'Arcachon.

Contribution à l'étude de la biologie et de la pêche du rouget-barbet (Mullus surmuletus) dans le Golfe de Gascogne
Provedor de dados: 5
Autores: Tous, Philippe.
The growth study of s tripped Mullet, from the Bay of Biscaye, from April to June is managed by scale reading. Sorne difficulties appear with the interpretation female scales. The Analysis of ovaries confirms that spring is the period of reproduction, and shows that the age of first reproduction is two year (65 %) or one year old (35 %). Secondly, the exploitation of various statistic data shows the evolution of landings of Stripped Mullet in several harbours, and especially in les Sables d'Olonne, since 1962.  The reconstitution of the artisan trowlers effort in this harbour confirms the long decline of c.p.u.e . for Mullus surmuletus, and a rapid increase since 1981. The problem of the lack of data about the inshore fishery and about the composition of...

Sardine series in PELGAS surveys : PELGAS 2000 to 2005
Provedor de dados: 5
Autores: Masse, Jacques; Duhamel, Erwan; Delaunay, Damien.
Survey data from 2000 to 2004 were used to analyse whether sardine show a preferential distribution in relation to bottom depth and/or latitude. For this analysis, four strata were considered; North or South of latitude 46°N (separating VIIIa and VIIIb) and bottom depths deeper or shallower than 110m. Sardine length distributions are plotted as the proportion of small (&lt; 18.5 cm) or big (larger than 18.5 cm) fish on the samples over the years. This division was chosen to take into account the bimodal structure of sardine length distributions (usually with a "valley" at 18.5 cm fish length). Small fish (mainly 1 year old) are generally found close to the coast and preferentially in the southern part. The year 2003 is different to the others but this year...

This document presents a comparative assessment of four triannual analyses carried out between 1986 and 1995, on 1300 boats, on average, from the 35 ports of Southern Bay of Biscay fishing fleets (from Loire river to Spanish border). Fisheries statistics allow the identification of different fishing practices and fishing boats associated with them within the fleets. In order to allow comparison and analysis of the evolution that has taken place during the study period, the same variables (gear used, landed species) and multivariate analysis procedures have been used to produce groupings of vessels Over the period, an average of 11 components have been identified, grouped in two entities, mobile and fixed gears.

Larval history of glass eels, Anguilla anguilla, (Linne, 1758) in migration in coastal and estuarine areas (Adour, Bay of Biscay) as revealed by otolith structure.
Provedor de dados: 5
Autores: De Casamajor, Marie-noelle; Lecomte Finiger, Raymonde; Prouzet, Patrick.
The embryonic past of glass eels vas studied from the interpretation of microstructures registered on otoliths. The aim of this work is to put in evidence possible seasonal modifications of the growth of otoliths so that differences between otoliths of glass eels caught off marine and estuarine environment. So during the season 1999-2000, from November till March, otolith sampling was realised in the Southwestern part of France, in an estuarine and coastal zone. We observed a spatial and temporal evolution of proportions of the three various types of otoliths taken into account. Glass eels sampled at sea sometimes have a mark on their otoliths indicating the transition in the estuary, especially at the end of the fishing season. Measures of growth marks of...

An acoustic survey was carried out in the bay of Biscay from May 3rd  to June 1st  on board the French research vessel Thalassa. The objective of PELGAS05 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".

La carotte MD95-2002, prélevée dans le Golfe de Gascogne (47°27'N; 08 °32'W, 2174m) a fait l'objet d'analyses micropaléontologiques afin de « documenter » les changements dans les conditions palée-hydrographiques de surface et de la colonne d'eau sous-jacente au cours de l'Holocène dans l'Atlantique nord-est. Les reconstructions quantitatives basées sur les assemblages de kystes de dinoflagellés (dinokystes) et les compositions isotopiques de foraminifères planctoniques ont permis de mettre en évidence des tendances à long terme auxquelles se superpose une importante variabilité climatique. Cette dernière se traduit principalement par des fortes variations des températures d'eau de surface (Sea-Surface Temperatures - SSTs) à l'Holocène inférieur, avec des...

This paper examines the effect of climate warming on the bio-economic performance of Bay of Biscay mixed fisheries and provides insights into the best management strategy for coping with global warming. To achieve this, a dynamic multi-species, multi-class, multi-fleets model is developed and calibrated using biological and environmental ICES and IPCC data. Fishing and economic data have been collected within the European DCF. The climate represented by the Sea Surface temperature is assumed to affect species recruitment. Three management strategies are then compared in terms of bio-economic outcomes: Status-Quo (SQ), Multi-species Maximum Sustainable Yield (MMSY), Multispecies Maximum Economic Yield (MMEY). Strategies are ranked with respect to two...

Modélisation bioénergétique de la variabilité des traits d’histoire de vie de l’anchois et de la sardine entre le golfe du Lion, le golfe de Gascogne et la Manche
Provedor de dados: 5
Autores: Menu, Clara.
Small pelagic fish show a general decrease in size and body condition over the past two decades in the North-East Atlantic. The underlying factors are still not well understood, however recent studies point to a bottom-up control. In order to understand how the environment impacts the main biological functions, i.e. growth, reproduction and maintenance, we adopted a bioenergetic modelling framework based on the Dynamic Energy Budget theory. To improve the robustness of our study, we chose a comparative approach between two species, Engraulis encrasicolus and Sardina pilchardus, both living in three areas, namely the English Channel, the Bay of Biscay and the Gulf of Lion. Our model is calibrated over the Bay of Biscay and then applied to the other areas,...

Autores: Blanchard, Michel; Heim, Marie; Rozec, Xavier; Caisey, Xavier.
This document presents a synthetic study of benthos in two large areas of the French coast: East-Channel and the area between Loire and Gironde. This original synthesis stocktakes biotopes maps published for the vast majority in the 70’s. The report uses the previous descriptions and analysis done by the different authors, and translates them with present specific names or biotopes codes, as proposed in the European EUNIS referring system. The presented maps are standardized and referred geographically with WGS84 to be collated together. For each biotope, specific richness and ecological richness are analysed, thanks to the information given by the various authors. Some informative cards of the main representative species are also presented in the...

Application d’un protocole de suivi habitat « récifs » au large de la côte basque. Application méthodologique Index-Cor
Provedor de dados: 5
Autores: De Casamajor, Marie-noelle; Lissardy, Muriel.
The purpose of this report is to test a sampling protocol to define a conservation status index for reef habitat in circalittoral environments to characterize benthic populations from surveys at 4 sites located in the Natura 2000 area “côte Basque rocky and extension offshore”. Due to the complexity of this habitat and the gaps in knowledge, an analysis of the protocol and its modalities is necessary. In parallel, optimization proposals are necessary for the relevance of the information provided and for apprehending a possible conservation status.
