Suivi stationnel de l’herbier à Zostera noltei de la masse d’eau FRFT8 Bidassoa – 2017. Bassin Hydrographique Adour-Garonne
Provedor de dados: 5
Autores: Sanchez, Florence; Lissardy, Muriel; De Casamajor, Marie-noelle.
The assessment of the angiosperm quality element (Zostera noltei) for transitional water body (here, FRFT8 Bidassoa) considers the monitoring of 3 metrics: the taxinomic composition, the spatial bed extent and the abundance (percentage cover). In 2017, the angiosperm quality element for FRFT8 Bidassoa was “good” as in 2015 and 2016. This result is due to a better percentage of seagrass cover. However, the spatial extent of seagrass continuously change, with new colonized areas.

In a context of several directives for transitional and coastal waters masses (Water Framework Directive, Marine Strategy Framework Directive and Bathing Water Directive), the good ecological status of water but also conservation of marine ecosystem should be quickly achieved. The Basque coastline (SE of the Bay of Biscay) is subject to strong human pressures with a high density of population over the year, and especially during the summer with tourist activities. It generates nutrient discharge, water and sediment pollution and impacts the quality of the marine environment. Such pressure and the way to reduce its impacts are the main concerns of authorities Locally, in order to improve wastewater treatment process, an alternative technical solution is...

The initial objective of the PELGAS integrated survey was to assess the biomass of small pelagic fish in the Bay of Biscay in spring. Sampling has been extended to study the spatial structure and dynamics of the pelagic ecosystem in springtime. The PELGAS survey has produced since 2000 long-term time-series of spatially-explicit data and indices, describing the main pelagic ecosystem components: hydrology, phytoplankton, mesozooplankton, fish and megafauna. In addition to small pelagic fish biomass estimates used for fish stock assessment, the survey now delivers two types of ecosystem products: standard gridded maps of ecosystem parameters, and a time series dataset of indicators of the Bay of Biscay pelagic ecosystem state. The evolution of the PELGAS...

A restricted fishing area as a tool for fisheries management: Example of the Capbreton canyon,southern Bay of Biscay
Provedor de dados: 5
Autores: Sanchez, Florence; Morandeau, Gilles; Bru, Noelle; Lissardy, Muriel.
Marine Protected Areas (MPAs) are generally considered as one of the most important tools, among the many regulations, designed to preserve marine resources as well as enhance fisheries. In the southern Bay of Biscay, local French fishermen requested creation of a restricted area to help settle disputes between the various métiers operating there. This restricted area, which lies mainly in French waters, covers part of a deep submarine canyon off the French and Spanish coasts, known to have a large population of mature hake. This study aims to better understand the effects of a restricted area upon French fleets operating there, particularly upon three main métiers – longliners, gillnetters and trawlers. The study area includes three ICES statistical...

Optimization of a survey using spatially balanced sampling: a single-year application of clam monitoring in the Arcachon Bay (SW France)
Provedor de dados: 5
Autores: Kermorvant, Claire; Caill-milly, Nathalie; D'Amico, Frank; Bru, Noelle; Sanchez, Florence; Lissardy, Muriel; Brown, Jennifer.
Bivalves are important components of benthic marine and freshwater ecosystems throughout the world. One of the most exploited bivalves used for human consumption is manila clam (Venerupis philippinarum). In Arcachon Bay (SW France), commercial fishers and scientists have developed a monitoring survey to estimate clam stocks to assist in implementing a sustainable management strategy. The survey design that is currently used is based on standard stratified random sampling (StRS). The survey has been undertaken every 2 years since 2006. Each survey costs approximately (sic) 50 000, with funding provided by similar to 20% of the commercial fishers. The survey is quite expensive, given that this resource is managed mostly at a regional level. In 2016 for...

Direct assessment of small pelagic fish by the PELGAS16 acoustic survey
Provedor de dados: 5
Autores: Duhamel, Erwan; Doray, Mathieu; Huret, Martin; Sanchez, Florence; Lespagnol, Patrick; Doremus, Ghislain; Lemerre, Charlotte.
The Pelgas16 acoustic survey has been carried out with very good weather conditions (regular low wind, medium temperatures) for the whole area, from the South of the bay of Biscay to the west of Brittany. The help of commercial vessels (two pairs of pelagic trawlers and a single one) during 18 days provided about 120 valid identification hauls instead of about 60 before 2007 when Thalassa was alone to identify echotraces. Their participation increased the precision of identification of echoes and some double hauls permitted to confirm that results provided by the two types of vessels (R/V and Fishing boats) were comparable and usable for biomass estimate purposes. These commercial vessels participated to the PELGAS survey in a very good spirit of...

L'exploitation des ressources par la pêche professionnelle et par la conchyliculture repose sur des ressources vivantes sauvages ou domestiquées qui sont présentes dans différents milieux aquatiques depuis les rivières jusqu'au large en mer. L'état de ces populations dépend non seulement des choix d'exploitation au regard des capacités de renouvellement des stocks mais aussi des caractéristiques environnementales qui impactent les différentes phases des cycles biologiques des espèces et jouent donc sur leur bon déroulement. Ces conditions du milieu sont tributaires pour partie des activités anthropiques (qualité et quantité d'eau disponible, obstacles au franchissement, autres perturbations) et peuvent être soumises aux effets du changement climatique.

Submarine canyons are major geomorphic features of continental margins around the world. Several recent multidisciplinary projects focused on the study of canyons have considerably increased our understanding of their ecological role, the goods, and services they provide to human populations, and the impacts that human activities have on their overall ecological condition. Pressures from human activities include fishing, dumping of land-based mine tailings, and oil and gas extraction. Moreover, hydrodynamic processes of canyons enhance the down-canyon transport of litter. The effects of climate change may modify the intensity of currents. This potential hydrographic change is predicted to impact the structure and functioning of canyon communities as well...

A partnership between science and industry for a monitoring of anchovy &amp; sardine in the Bay of Biscay: When fishermen are actors of science
Provedor de dados: 5
Autores: Masse, Jacques; Sanchez, Florence; Delaunay, Damien; Robert, J. M.; Petitgas, Pierre.
Anchovy and sardine are small pelagic species occupying similar geographic areas in the Bay of Biscay (North-East Atlantic). Their biomass is strongly dependent on recruitment, making the annual assessment of TAC (Total Allowable Catch) a risky strategy due to uncertainty in predicting the magnitude of recruitment. Monitoring these resources more often and throughout their life cycle could allow management strategies to be adjusted based on observations which indicate the level of recruitment. In order to achieve a more frequent monitoring, an innovative data collection strategy involving a partnership between fishermen and scientists, was developed in 2009 and 2010 called “pilot sentinel surveys”. This paper details the partnership, the information such a...

Why do fishermen discard? Distribution and quantification of the causes of discards in the Southern Bay of Biscay passive gear fisheries.
Provedor de dados: 5
Autores: Morandeau, Gilles; Macher, Claire; Sanchez, Florence; Bru, Noelle; Fauconnet, Laurence; Caill-milly, Nathalie.
In the context of the Common Fisheries Policy reform, the need for decreasing discards has been highlighted in discussions on the implementation of a discard ban. While most of the research has focused on the quantification of discards by species and métier, identification and quantification of the causes of discards have received little attention. This study presents the results of on-board surveys conducted in the Southern Bay of Biscay fleets of netters and longliners. A large variability of discards was observed. It is also shown that in these passive gear fisheries the main reasons for discarding put forward by fishermen are, firstly, market-related and, secondly, quality-related; discards related to the application of regulations are minor.

Autores: Sanchez, Florence; Lissardy, Muriel; De Casamajor, Marie-noelle; Aubert, Fabien.
In 2020, the Zostera noltei seagrass bed monitoring, located on the transitional water body FRFT08 Bidassoa (Txingudi Bay, Hendaye - Pyrénées Atlantiques), was carried out from a grid of 30 sample points ("stationary" monitoring) and from a mapping within the framework of the WFD. The "angiosperms" indicator established on this water body is based on 3 metrics (composition, extent and abundance). In 2020, the calculation of this indicator classifies the water body in "Very good condition". This result is explained both by a significant increase in the seagrass bed surface area, from 1.9 ha in 2018 to 4.5 ha in 2020 and by a good abundance.

Certaines masses d’eau s’avérant parfois déclassées par cet élément de qualité, le groupe de travail DCE « Eaux Littorales » a sollicité de la part des scientifiques une réflexion sur les raisons de ce mauvais classement et les éventuelles actions de restauration ou d'amélioration de connaissances relatives aux herbiers de ces zones. L’objectif de cette expertise, soutenue par l’Agence Française pour la Biodiversité, et réalisée en collaboration avec les acteurs concernés par l’indicateur « angiospermes » sur les façades Manche-Atlantique, est d’identifier les pressions potentiellement responsables de cette situation (Tableau 1) en prenant également en compte l’effet des différentes métriques de l’indicateur sur les résultats obtenus.

The initial focus of the PELGAS integrated survey was to assess the small pelagic fish biomass in the Bay of Biscay in springtime, for fisheries management purposes. Sampling has been extended to produce long-term time-series of spatially-explicit data and indices, describing the main pelagic ecosystem components: hydrology, phytoplankton, mesozooplankton, fish and megafauna. A collaborative analysis of these datasets has brought new insights on the Bay of Biscay pelagic ecosystem summarized here. New results on single ecosystem components include an analysis of water samples to groundtruth the results of an ocean color algorithm aiming at detecting phytoplanktonic coccolithophores. New insights on mesozooplankton spatio-temporal distribution and energy...

Provedor de dados: 5
Autores: Duhamel, Erwan; Doray, Mathieu; Huret, Martin; Sanchez, Florence; Lespagnol, Patrick; Doremus, Gislain; Le Bourdonnec, Pierre.
An acoustic survey (PELGAS) is carried out every year in the Bay of Biscay in spring onboard the French research vessel Thalassa. The objective of PELGAS survey is to study the abundance and distribution of pelagic fish in the Bay of Biscay. The main target species are anchovy and sardine but they are considered in a multi-specific context and within an ecosystemic approach as they are located in the centre of pelagic ecosystem. The Pelgas17 acoustic survey has been carried out with medium weather conditions (regular wind, low atmospheric temperatures) for the whole area, from the South of the bay of Biscay to the west of Brittany. The help of commercial vessels (two pairs of pelagic trawlers and a single one) during 18 days provided about 110 valid...

The Pelgas15 acoustic survey has been carried out with globally good weather conditions (regular low wind, medium temperatures) for the whole area, from the South of the bay of Biscay to the west of Brittany. The help of commercial vessels (two pairs of pelagic trawlers and a single one) during 18 days provided about 130 valid identification hauls instead of about 50 before 2007 when Thalassa was alone to identify echotraces. Their participation increased the precision of identification of echoes and some double hauls permitted to confirm that results provided by the two types of vessels (R/V and Fishing boats) were comparable and usable for biomass estimate purposes. These commercial vessels participated to the PELGAS survey in a very good spirit of...

Asari (= Manila) clam, Ruditapes philippinarum, is the second bivalve mollusc in terms of production in the world and, in many coastal areas, can beget important socio-economic issues. In Europe, this species was introduced after 1973. In Arcachon Bay, after a decade of aquaculture attempt, Asari clam rapidly constituted neo-naturalized population which is now fished. However, recent studies emphasized the decline of population and individual performances. In the framework of a national project (REPAMEP), some elements of fitness, stressors and responses in Arcachon bay were measured and compared to international data (41 publications, 9 countries). The condition index (CI=flesh weight/shell weight) was the lowest among all compared sites. Variation in...

Autores: De Casamajor, Marie-noelle; Lissardy, Muriel; Sanchez, Florence.
In 2018, the calculation of the DCE indicator "intertidal macroalgae" for FRFC11 water body "Basque coast" allowed to classify it as "Good" for this parameter in spring and “Medium” in autumn. This monitoring is the first data collection campaign in line with an evolution of the indicator and the MSFD needs: double sampling in spring and autumn, consideration of the fauna in quadrats and a taxonomic identification effort. These additional data are presented through the indicator Ics (Community Structure Indicator) but are not scored at this stage. The lack of canopy in the intertidal zone and the biogeography for this water body are two aspects that should be considered in the scales that will be applied to assess the conservation status of intertidal...

Suivis stationnel et surfacique de l’herbier à Zostera noltei de la masse d’eau FRFT8 Bidassoa – 2013 - Bassin Hydrographique Adour-Garonne -

The new protocol, established by Auby et al. (2012) to the seagrass monitoring under the Water Framework Directive, was used in Txingudi bay (Hendaye, France). Based on 3 metrics ("taxonomy", "extension" and "density"), the quality index of the water body for the angiosperm indicator, was "medium", while it was in "good condition" in 2012. These results are explained by a sharp drop in the density observed on the monitoring station. The cartography of the species distribution showed a decrease of the total area of seagrass, particularly in the southern part of the mudflat. However, further north, small intertidal seagrass spots appeared. Atypical weather conditions in 2013 (cold, heavy spring rain) with silting of this area, could explain this situation.

The objective of fisheries management is the sustainable exploitation of the fish resources over the extent of their spatial distribution. Along with the Common Fisheries Policy (CFP) objectives, the socio-economic viability of the fisheries exploiting the resource is also to be achieved. To reach these aims, managers need to define the management units they are going to work with. For the purpose of GEPETO project, we define a management unit (MU) as the set of fishing fleets exploiting a common pool of fish resources with strong spatial overlapping and sharing of habitats, which make them being typically fished together. In other words, a MU is the set of fishing fleets exploiting a common fish community over their spatial distribution. MUs have to be...

The Pélagiques Gascogne (PELGAS) integrated survey has been developed by a multidisciplinary team of Ifremer and La Rochelle University scientists since 2000, joined by commercial fishermen in 2007. Its initial focus was to assess the biomass and predict the recruitment success of anchovy in the Bay of Biscay in spring. Taking advantage of the space and versatility of R/V Thalassa II, sampling has been progressively extended to other ecosystem components. PELGAS therefore further developed the second objective of monitoring and studying the dynamic and diverse Biscay pelagic ecosystem in springtime. The PELGAS survey model has allowed for the establishment of a long-term time-series of spatially-explicit data of the Bay of Biscay pelagic ecosystem since...
