A partnership between science and industry for a monitoring of anchovy & sardine in the Bay of Biscay: When fishermen are actors of science ArchiMer
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...

A restricted fishing area as a tool for fisheries management: Example of the Capbreton canyon,southern Bay of Biscay ArchiMer
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...

Assessment of the impact of a wastewater treatment process including Advanced Oxidation Technique on environment using chemical and biological indicators ArchiMer
Caill-milly, Nathalie; De Casamajor, Marie-noelle; Pigot, Thierry; Paulin, Thomas; Bru, Noëlle; Sanchez, Florence; Marticorena, Julien; Lanceleur, Laurent; Gonzalez, Patrice; Daffe, Guillemine.
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...

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 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...

Direct assessment of small pelagic fish by the PELGAS15 acoustic survey ArchiMer
Duhamel, Erwan; Doray, Mathieu; Huret, Martin; Sanchez, Florence; Authier, Matthieu; Bergot, Patricia.
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...

Ecological Role of Submarine Canyons and Need for Canyon Conservation: A Review ArchiMer
Fernandez-arcaya, Ulla; Ramirez-llodra, Eva; Aguzzi, Jacopo; Allcock, A. Louise; Davies, Jaime S.; Dissanayake, Awantha; Harris, Peter; Howell, Kerry; Huvenne, Veerle A.i.; Macmillan-lawler, Miles; Martín, Jacobo; Menot, Lenaick; Nizinski, Martha; Puig, Pere; Rowden, Ashley A.; Sanchez, Florence; Van Den Beld, Inge.
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...

Guidelines for the definition of operational management units ArchiMer
Uriarte, Andres; Zarauz, Lucia; Aranda, Martin; Santurtun, Marina; Iriondo, Ane; Berthou, Patrick; Castro, Jose; Delayat, Stephanie; Falcon, Jesus; Garcia, Javier; Gaspar, Miguel; Gonzalez, J.f.; Jimenez, Sebastian; Lordan, Colm; Morandeau, Gilles; Sanchez, Florence; Santamaria, Maria Theresa; Villegas, Noemi.
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...

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.
