The sea urchin Paracentrotus lividus is an important exploited resource on the Mediterranean coast and has been the subject of much research. In the Bay of Biscay, the situation is different, as some studies have been conducted on the Spanish Basque coast but few on the French part of that coast. However, the Basque coast offers favourable conditions for the development of this species, and its exploitation could be a source of potential diversification for fishermen, especially in the context of difficulties with some other resources. At the request of the managers of this coastal resource, a study was undertaken on sea urchins to improve knowledge of this stock, particularly about its biological characteristics. In this work, assessment consisted of...

First record of Parapristipoma octolineatum (Haemulidae) on the French Atlantic coast.
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: 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.

The rocky Basque coast presents an interest both in terms of biogeography and its patrimonial situation, alongside its habitats, fauna and flora. The aim of the BIGORNO project (Intertidal Biodiversity of the south of the Bay of Biscay and Observation for New research and Monitoring for decision support), financed by the Agency of Marine Protected Areas (AAMP) and the Departmental Council (CD 64), is to respond to significant deficiencies on biocenosis in the southern marine subregion “Bay of Biscay”. Investigations carried out in the WFD, since 2008, constitute an important basis of work for integration of fauna. Field studies undertaken since 2015 consisting of a sampling design suited to the substrates heterogeneity and the presence of microhabitats...

Cystoseira baccata, a biological quality element for the implementation of the Water Framework and Marine Strategy EU Directives, is a dominant species in the subtidal rocky bottoms of the Basque coast. As part of this issue and given the need to better understand the functional character of benthic rocky ecosystems and use them as a reference to anthropogenic changes, two samplings campaigns were conducted in 2014 and 2017. Several population parameters (i.e. frond density, frond length frond-length/total frond-length ratio and taxonomic richness of epibionts) of C. baccata were studied from three sites monitored within the Water Directive Framework in relation to bathymetry during the two campaigns. The results showed a significant influence of...

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...

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: Institutional Archive of Ifreme (ArchiMer)
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...

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.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: De Casamajor, Marie-noelle; Prouzet, Patrick; Lazure, Pascal.
Biological data on glass eels (Anguilla anguilla) were collected during two successive sampling periods from November to March (1996-1997 and 1997-1998) on the Adour estuary. As for other estuaries, decrease in length (mean of 73.5 to 67.4 mm) and weight (mean of 3.5 to 2.6 dg) of glass eels were observed. Weight and length characteristics were used to identify groups of glass eels. These groups were well distinguished during the first sampling period but some overlaps appeared in the second one. Fluctuations of static allometry and similarity coefficients showed successive glass eels arrivals in the lower part of the estuary during the two seasons. We used fluctuations of the index of similarity in the second period to describe arrivals of glass-eels...

Autores: De Casamajor, Marie-noelle; Duval, Magali; Plus, Martin; Lissardy, Muriel.
Under the WFD monitoring the “subtidal macroalgae” parameter is calculated for the second time on the Basque coast water body from the protocol used in Britain and adapted to local environmental context. In 2011, three stations were sampled instead of 5 in 2008. The result is the same to the one obtained in 2008 with a quality index "medium" for the whole of the water body. The main criterion penalizing the calculation of the index is "opportunistic species" for each station. There is variability between sites according to the criteria between the two campaigns reflecting the interest of monitoring every three years on the three sites.

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...

In compliance with the Water Framework Directive (WFD), the good ecological status assessment for Channel-Atlantic coastal water bodies is currently carried out in the intertidal and subtidal zones using a biological indicator based on macroalgae on the rocky coasts. The second step of this Directive (2016-2021) deals with the workings of the marine ecosystem. Therefore, macrofauna has also to be taken into account in the both zones. Current works about the WFD indicator of pressure-impact interactions show deficiencies on how the biological indicators respond to each pressure regarding magnitude and type. Therefore, the implementation of a monitoring program on the southern rocky coast is essential to understand and assess the proper ecological condition...

Rocky intertidal habitats are particularly vulnerable to anthropogenic pressures especially in areas with high urban concentrations such as southeastern Bay of Biscay. This research aims to establish an assessment of the potential impact of sewage discharges on intertidal rocky benthic assemblages on macroalgae and on macrofauna as required by the European Directives (Water Framework Directive -WFD and Marine Strategy Framework Directive -MSFD). The assemblages were sampled at five locations according to a control-impact design. A moderate detectable effect of discharges was highlighted on the assemblage structure by means of multivariate analyses but this was less evident using other biological and ecological metrics. Results would also suggest that...

Autores: De Casamajor, Marie-noelle; Popovsky, Josiane; Lissardy, Muriel.
In 2013, under the WFD monitoring the "subtidal macroalgae" parameter is calculated on 3 stations of the “Basque coast” water body. The classification for this parameter is "good", and scores obtained are higher than the previous years. This observation is mainly based on the fact that deeper bathymetric levels were sampled and allowed to better characterize belts and associated communities. The effects of bad spring weather conditions on algae growth are not visible at the time of sampling. After these first three sampling campains improvements and additions to the protocol are proposed to provide information for European directives.

Quantification of a rock platform bioerosion by the sea urchin Paracentrotus lividus (Lamarck, 1816) the Basque Coast case (Bay of Biscay)
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Regard, V.; De Casamajor, Marie-noelle; Maillet, G.; Prémaillon, M.; Caill-milly, Nathalie.
The French Basque Coast is an actively eroding rocky coast. In the study area it is made of flysch with a circa 40 degrees-dip; it is exposed to an average significant wave height of 1.8 m and peak  period of 9.6 s. It is mesotidal (spring tide of ~4m). The current rocky shore platform is carved into the flysch layering. We focus on sea urchin Paracentrotus lividus contribution to rock shore erosion. Indeed, this sea urchin has a burrowing behaviour. An ecological study has been conducted for stock assessment, from shore to 10 m-deep. It indicates that sea urchins are burying their own shelter and are not reusing former ones. Below the depth of 10 m, sea urchins densities are very low and burial behavior is considered insignificant. Estimates of sea urchin...

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....

Suivi stationnel de l’herbier à Zostera noltei de la masse d’eau FRFT8 Bidassoa. 2016 - Bassin Hydrographique Adour-Garonne -
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Sanchez, Florence; Lissardy, Muriel; De Casamajor, Marie-noelle.
The assessment of the angiosperm quality element (Zostera noltei) considers the monitoring of 3 metrics: the taxinomic composition, the spatial bed extent and the abundance (percentage cover). In 2016, for the FRFT8 Bidassoa water body, the ecological status for the angiosperm element was “good”, as in 2015. This result is due to a better percentage of seagrass cover but the spatial extent decreased (-33 % compared to 2015). This spatial decline could lead to a worse classification in next years

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.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
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.

Under the WFD monitoring, the intertidal macroalga parameter of the water body FRFC11 « coast Basque », two stations were sampled in 2015 from the appropriate protocol for this water body. The average of the two stations takes the water body in « Good ». Both stations get very similar results but are not classified in the same category: « Good » . The abundance of opportunistic species is the worst notation. The comparison with results for subtidal macroalgae is consistent. Also, for intertidal macroalgae on Spanich Basque waterbodies results are very similar.

Along biometric characteristics, glass eel otoliths were collected during three migration seasons, in the Adour estuary, during the new moon of January. Microstructure reading and measurements of various growth zones bring information on glass eel larval life during their oceanic migration and the transition phase in estuary. The results show significant inter-annual variations of glass eels otolithometric characteristics from the point of view of their typology as of the various growth zones measured during transoceanic migration. The differences observed between the years on the typology level could be related to very fluctuating environmental conditions during recruitment. The differences in measurements carried out on the registered otolith zones would...

An index CCO (cover, characteristic species, opportunistic species) has been developed for the implementation of the European Water Framework Directory (WFD) in coastal waters, using intertidal macroalgal communities as bio-indicator (Biological Quality Element). CCO is based on the calculation of three metrics corresponding to the global cover of macroalgal communities (metric 1), the number of characteristic species per topographic level/seaweed community (metric 2) and the cover of opportunistic species (metric 3). The final rating is obtained by pooling the scores of the three metrics. Results are given for 32 sites in 29 water bodies, grouped into four biogeographic regions along the Channel–Atlantic coasts of France. Over the six-year study, most of...

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,...

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.

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...

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...

Autores: 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...

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.

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).

This paper investigates whether morphological variability of test and Aristotle’s lantern can be detected in sea urchins exposed to domestic pollution and whether this variability can be also related to tidal level and hydrodynamic features. The study was conducted on four sites along the French Basque coast. Each site is characterized by its geological layers’ orientation, regardless of its proximity to sewage outlets. Analyses on high-resolution pictures of jaws were performed and three parameters were retained: length, height and demipyramid dry mass. Five shape descriptors were consequently defined regarding the test and the jaws. Individuals with heavy test density associated with highly developed demipyramid regarding test diameter and height were...

Suivi DCE du paramètre « macroalgues subtidales » dans la masse d’eau « côte basque »
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: De Casamajor, Marie-noelle; Lissardy, Muriel.
Since 2008, the parameter “macroalgae subtidales” is calculated on 3 stations of the water mass FRFC11 Basque coast. In the second cycle of WDF monitoring, complementary metrics are calculated as for the entire Channel / Atlantic facade. These metrics were measured for the second time in 2017 and aim to optimize the information collected to assess the ecological status of water bodies but also to characterize the functionality of the ecosystem. The calculation of the Ecological Quality Ratio (EQR) makes it possible to classify this water mass in “Good” as the previous campaigns with a tendency to improve the rating during the whole period.

Autores: Debenay, Jean-pierre; Geslin, Emmanuelle; Guillou, Jean-jacques; De Casamajor, Marie-noelle.
This work is based on about 2,000 samples. It provides a synthetic description of the distribution patterns of fûraminiferal assemblages in paralie environments and shows on two examples the effect of anthropogenic impacts. It shows that despite the great diversity of eeological parameters, foraminiferal assemblages are naturally distributeà along a fev/ major gradients. Anomalies in these distribution patterns or morphological abnormalities of the tests indicate anthropogenic or natural stresses. An increase in the number of individuals, specifie richness and test size indicate organic pollution while chemicai pollution as an inverse effect. ln Port-Joinville harbour, Cribroelphidium excavatum and Haynesina gennanica characterize the areas submited to the...

Prospection et échantillonnage des émissaires en mer au large de la côte basque. Rapport de campagne - Micropolit année 1
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: De Casamajor, Marie-noelle; Huguenin, Laura; Lissardy, Muriel.
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.

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".
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: 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...

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: De Casamajor, Marie-noelle; Lalanne, Yann.
During recent decades, works on rocky shore biodiversity have been multiplied in the southern part of the Bay of Biscay and more precisely on intertidal and subtidal area were communities present a great interest. Necessity of conservation of coastal habitats and their communities and a growing pressure on coastal environments explain awareness of services provided by these ecosystems. Those communities are very sensitive to water quality change. Moreover, since the beginning of the XXI century various European directives require a good ecological status of coastal waters and conservation of their communities : Water Framework Directive (WFD), Marine Strategy Framework Directive (MSFD) and conservation of habitats with Directive Habitat Fauna and Flora...

Rocky shore benthic communities as indicators of global change in the context of European directives
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: De Casamajor, Marie-noelle; Lalanne, Yann; Huguenin, Laura; Oger-jeanneret, Helene.
The implementation of European Directives in the last decade (WFD, MSFD, DHFF) shows a growing interest in assessing the environmental status of coastal areas in maintaining the ecosystems functionality and biodiversity conservation. In this context, investigations on benthic communities were launched to increase knowledge on taxonomic composition and their spatial distribution. On the Basque coast, rocky shores present remarkable habitats and biogeographic specificities, both in intertidal and subtidal areas. These productive environments, covered with shallow seaweed beds, have a high functionality such as nursery and a protective function for many species during their life cycle. At the scale of marine sub-area of the Bay of Biscay, data available...

Autores: Sanchez, Florence; Lissardy, Muriel; De Casamajor, Marie-noelle.
The new protocol established by Auby et al. (2012) was applied in 2014 to the seagrass monitoring in the Water body FRFT8 – Bidassoa - Type T03. Based on 3 metrics ("taxonomy", "extension" and "abundance"), the quality index of this water body for the angiosperm indicator, was "good". The displacement of the seagrass bed led us to adapt the sampling grid in 2014

Suivi stationnel de l’herbier à Zostera noltei de la masse d’eau FRFT08 Bidassoa - 2018 - Bassin Hydrographique Adour-Garonne
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
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 2018, the angiosperm quality element for FRFT8 Bidassoa was “good” such as 2016 and 2017. This result is due to an increase of the spatial extent of seagrass bed compared to 2016. However, the spatial extent of seagrass continuously change, depending on climatic conditions of the year.
