Analyse des ressources et des caractéristiques individuelles du stock d'oursin Paracentrotus lividus (Lamarck, 1816) du territoire 64 ArchiMer
De Casamajor, Marie-noelle; Mahias, Jeremy; Bru, Noelle; Caill-milly, Nathalie.
A spatial sampling was carried out for stock assessment of sea urchin P. lividus throughout the Basque coast. A sampling, over the year, was conducted to study the reproductive cycle. This work took place over 2013 and 2014. Reproduction occurs once in spring, between May and August 2014. Among factors affecting the release of eggs, salinity, temperature and hydrodynamics show a significant inter-annual variability in the Basque coast. Thus, the period set in 2014, may fluctuate between years. For the stock, the results showed that 11.85 (+/-0.32) million individuals of harvestable biomass for 724 tones (+/- 137). Stock is spread over the entire surveyed area density and biomass decrease rapidly with depth, individuals are mainly located between 0 and 5 m....

Application d’un protocole de suivi habitat « récifs » au large de la côte basque. Application méthodologique Index-Cor ArchiMer
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.

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...

Atlas thématique de l'environnement marin du Pays basque et du sud des Landes ArchiMer
De Casamajor, Marie-noelle; Augris, Claude; Caill-milly, Nathalie.
On imagine souvent les fonds marins proches comme une vaste étendue monotone qui prolonge le littoral, espace de loisir, de découverte et de rêverie. Le recueil d’informations présenté ici sous la forme d’un atlas agrémenté de riches illustrations témoigne du contraire. Le domaine marin côtier du Pays basque et du sud des Landes a fait l’objet de nombreux travaux thématiques sur le milieu physique, le milieu vivant, les ressources halieutiques et les activités qui s’y pratiquent. Un important travail de synthèse a été réalisé par des équipes scientifiques qui, à des degrés divers, se sont investies pour mettre leurs résultats à la portée du plus grand nombre. Elles ont voulu transmettre leurs connaissances mais également leur passion pour cette façade...

BIGORNO. Biodiversité Intertidale sud Gascogne Observation et Recherche de Nouveaux Outils de surveillance et d'aide à la décision - Rapport fiinal ArchiMer
De Casamajor, Marie-noelle; Lalanne, Yann; Huguenin, Laura; Marticorena, Julien; Lissardy, Muriel; Bru, Noelle; D'Amico, Franck; Liquet, Benoît.
This report presents the results obtained during the BIGORNO project whose main objective is to overcome knowledge gaps on the biocenoses of the southern sub-region "Bay of Biscay" to propose a sampling protocol adapted to biogeographic and environmental specific conditions. A stratified random sampling design considering spatial heterogeneity has been implemented. Biodiversity was considered on 0.1 m²quadrats. These data have revealed the organization of benthic communities and the relevant taxa to be considered (species or assemblages of indicator species) in the context of establishing perennial monitoring of intertidal habitats. Proposals are made to implement the descriptors and indicators defined in the Marine Strategy Framework Directive (MSFD).

BIGORNO Project. Intertidal biodiversity in the south of Bay of Biscay new research tools in a context of implementation of the Marine Strategy Framework Directive (MSFD) ArchiMer
De Casamajor, Marie-noelle; Huguenin, Laura; Marticorena, Julien; Lalanne, Yann; Bru, Noelle; Liquet, Benoît; Lissardy, Muriel; D'Amico, Franck; Castege, Iker; Milon, Emilie.
Biodiversity conservation and response of benthic communities to pressures, related to global change and human activities, are a research priority. They also constitute a useful indicator to define the environmental status of the Marine Strategy Framework Directive as part of the European Water Framework Directive (WFD). The biogeographic features of the Aquitanian coast (in terms of rocky substrate communities) induce the interest to have a monitoring and research site. Indeed, it includes the habitat characteristics as well as fauna and flora (the Habitats Directive). The aim of the BIGORNO project is to implement new tools to assess the rocky biocenosis in the southern marine subregion of the Bay of Biscay by integrating fauna communities assessment...

Classement des masses d’eau du littoral Manche-Atlantique sur la base de l’indicateur DCE «Angiospermes» (2012-2016) ArchiMer
Auby, Isabelle; Oger-jeanneret, Helene; Trut, Gilles; Ganthy, Florian; Rigouin, Loic; De Casamajor, Marie-noelle; Sanchez, Florence; Lissardy, Muriel; Fortune, Mireille; Manach, Soazig; Bizzozero, Lucie; Rollet, Claire; Lejolivet, Aurore; Desroy, Nicolas; Foveau, Aurelie; Le Mao, Patrick; Sauriau, P.g.; Aubert, A.; Cajeri, P.; Curti, C.; Duvard, A.; Latry, L.; Lachaussee, N.; Pineau, P.; Plumejeaud-perreau, C.; Aubin, S.; Droual, G.; Fournier, J.; Garcia, A; Guillaudeau, J.; Hubert, C.; Humbert, S.; Janson, A.l.; Masse, C.; Panizza, A.c.; Grall, J.; Maguer, M.; Hily, C.; Hacquebart, P.; Joncourt, Y.; Baffreau, A.; Timsit, O..
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.

Does spatial distribution of fauna depend on algal belts on intertidal boulder fields of the French Basque coast ? ArchiMer
Marticorena, Julien; Huguenin, Laura; Lalanne, Yann; Bru, Noelle; Liquet, Benoît; De Casamajor, Marie-noelle.
To determine good ecological status and conservation of the Sub-Marine area of the Bay of Biscay, the implementation of a new rocky intertidal habitats monitoring is needed. A protocol has been adapted from the Brittany protocol for the water body FRFC11 "Basque coast" for the two indicators "intertidal macroalgae" and "subtidal macroalgae" under the Water Framework Directive to qualify the ecological. However no protocol has been validated for fauna in front of meridional characters of the benthic communities. Investigations carried out on macroalgae communities on intertidal area in WFD framework, since 2008, constitute an important working basis. This is the aim of the Bigorno project (Intertidal Biodiversity of the south of the Bay of Biscay and...

De Casamajor, Marie-noelle; Morandeau, Gilles.
This report summarise the ichthyological data collected by the laboratory on unusual catches of the Aquitain coast. They are intended to fishermen who transmit information and are also displayed in the fishing market to allow feedback to the profession. Species are classified according to their ecological affinity and their families in a second way. The unusual nature of the capture is also mentioned if it is a first catch of the specie, if it is observed occasionally or more regularly in the landings. A review is made after 15 years of collecting information and perspectives it would be interesting to develop are reported .

Étude prospective de l'exploitation des coquillages au large des côtes d'Aquitaine Volet : Ressources et première approche économique ArchiMer
Caill-milly, Nathalie; Duclercq, Benoit; Morandeau, Gilles; De Casamajor, Marie-noelle.
Introduction: With the objective of diversifying current fishing and at the request of professionals in Aquitaine, the Regional Commission of Maritime Fishing and Marine Breeding (CRPMEM) of Aquitaine has started a discussion about the possibilities of opening a shellfishery. In the context of this course of action, and because of the absence of information on the presence and size of the resource, the CRPMEM of Aquitaine asked IFREMER's Halieutic Resources Laboratory of Aquitaine (LRHA) for assistance in acquiring information on the subject. At the same time, a prospective analysis study of the exploitation of shellfish off the coast of Aquitaine—regulation and business section—was performed by the CRPMEM of Aquitaine (Coiffec, 2006). At that same time,...

First record of Parapristipoma octolineatum (Haemulidae) on the French Atlantic coast. ArchiMer
De Casamajor, Marie-noelle.
A specimen of African striped grunt Parapristipoma octolineatum was observed on the French part of the Bay of Biscay. This is the first and the most northern record of this species in the Northeastern Atlantic. Moreover, no specimen of this family was ever listed in this geographical area. Repeated observations of the same individual during the four consecutive past years in summer (2013-2016), suggest its adaptation to environmental conditions of this area.

Fluctuations des captures de civelles (Anguilla Anguilla L.) et analyse de la variation de leur capturabilité dans l'estuaire de l'Adour ArchiMer
De Casamajor, Marie-noelle; Bru, N.; Prouzet, Patrick.
Analysis of glass eels catches from 1927 to 1998 in the Adour estuary showed different periods of successive decrease. Fishing periods between 1985 to 1993 were studied iwn order to observe impact of hydroclimatic conditions on the level of catch per unit of effort. This study took place in January when glass eels accessibility by the fishery was generally the highest. With hand and trawl netting that filtered the upper part of the water column, only individuals located close to the surface were accessible. Consequently, factors acting on the migration of glass eels in the water column have a great importance on the fishing success. Among environmental conditions, moon phase and temperature influence were determinant factors on catch variability but a lack...

How determining a small set of indicator species useful in environmental monitoring? A case study of intertidal boulder fields macrofauna (Northern Basque coast) using the R package "indicspecies". ArchiMer
Lalanne, Yann; Huguenin, Laura; De Casamajor, Marie-noelle.
Ecological  indicators are useful to monitor environmental changes and assess ecological management and conservation. They provide information to understand the environment and its health status while also highlighting changes in the environment by giving early warning signals. Among them, the identification of indicator species add ecological meaning to studied sites and their use is an alternative to sampling the entire biodiversity. The northern Basque  coast (located in  the  South  of  the  Bay  of  Biscay marine sub-area  - France) is  dominated by remarkable rocky habitats as stable platforms and mobile boulder fields exposed to swells and freshwater incomes. Recently, the context of the Marine Strategy Framework Directive emphasized significant...
