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.

Provedor de dados: 5
Autores: Gallet, François; Ducommun-rigole, Laure; Caill-milly, Nathalie; Lesueur, Marie; Gueguen, Anthony; Lissardy, Muriel; Morandeau, Gilles; Le Grand, Christelle.
En 2007, le CIDPMEM 64-40 (alors CLPMEM de Bayonne), avait porté une étude sur le poids socio-économique de la filière pêche du quartier maritime de Bayonne. Elle avait permis de décrire le système halieutique local et de quantifier l’impact économique et social de l’activité de pêche sur le territoire par la quantification des flux monétaires entre acteurs et la quantification des emplois générés par l’activité de pêche. Même si les indicateurs définis lors cette précédente étude font toujours référence, le contexte de la filière a très sensiblement évolué en 10 ans et il est apparu indispensable non seulement de mettre à jour les différents indicateurs mais aussi de s'intéresser à des focus particuliers. Le CIDPMEM64-40 a donc à nouveau réuni un ensemble...

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...

Prospection et échantillonnage des émissaires en mer au large de la côte basque. Rapport de campagne - Micropolit année 1
Provedor de dados: 5
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.

Autores: Leaute, Jean-pierre; Caill-milly, Nathalie; Lissardy, Muriel.
This document present the whiting part of the study Striped red mullet (Mullus surmuletus), whiting (Merlangius merlangus) and pollack (Pollachius pollachius) are three species for which individualization of stocks is advanced by ICES in western Europe for areas including the Bay of Biscay and the areas bordering the Iberian peninsula. Since 2012, ICES has provided recommendations with regards to these stocks. These recommendations are given for two‐year periods and are based on an approach adopted by ICES in 2012 in the case of insufficient data for an analytical evaluation (Data Limited Stocks, DLS). For 2013 and 2014, ICES recommended reducing catches by 20% as a precautionary measure compared to 2009‐2011 for the three stocks. Considering that TACs are...

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...

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...

Tidal level influence on the spawning process of the sea urchin Paracentrotus lividus (Lamarck, 1816) on a rocky shore (Bay of Biscay).
Provedor de dados: 5
Autores: De Casamajor, Marie-noelle; Mahias, Jeremy; Castets, Virginie; Caill-milly, Nathalie; Bru, Noelle; Lissardy, Muriel.
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...

Suivi stationnel de l’herbier à Zostera noltei de la masse d’eau FRFT08 Bidassoa - 2018 - 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 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.

Suivi DCE du paramètre « macroalgues subtidales » dans la masse d’eau « côte basque »
Provedor de dados: 5
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.

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.

Autores: Caill-milly, Nathalie; Lissardy, Muriel; Bru, Noëlle.
The ROMELIGO project included a proposal of abundance indicators for whg-89a stock using professional fishing data. The methodolgy is based on the selection of a sample of representative vessels grouped in a cluster with the same technical characteristics, taking into account their LPUE for specifed period and area. The analysis was conducted on an historical dataset from 2010 to 2015. To be able to update it, a conditional decision tree was used to find rules to assign any new vessels to one of the predefined OTB clusters. Then, the trends of LPUE on the overall period were considered. In recent years, the north shows low levels, but the decrease is not significant over the whole period (Pearson test). For the south, no trend emerges. Professionals...

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.

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.

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...

Autores: Sanchez, Florence; Lissardy, Muriel; De Casamajor, Marie-noelle; Aubert, Fabien.
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 2019, the angiosperm quality element for FRFT8 Bidassoa was “very good”. This result is due to an increase of the abundance of seagrass bed compared to 2018.

In 2014, under the second cycle of WFD monitoring the "subtidal macroalgae" parameter is calculated on 3 stations of the “Basque coast” water body. Complementary metric have been obtained for the first time, as for all the Channel / Atlantic coast. Their aim is to optimize the information collected to assess the ecological status of water bodies. The calculation of the Ecological Quality Ratio (EQR) classify this water body as "Good" as in 2013 with a tendency to improve notation.

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

The ROMELIGO project included a proposal of abundance indicators for mur-west stock using professional fishing data. The methodolgy is based on the selection of samples of representative vessels grouped in clusters with the same technical characteristics, taking into account their LPUE for specifed period and area. The analysis was conducted on an historical dataset from 2005 to 2015. To be able to update it, conditional decision trees were used to find rules to assign any new vessels to one of the predefined OTB or GNS clusters. Then, the trends of LPUE on the overall period were considered. For OTB, the number of uses shows little variation during the period. In recent years, the LPUEs calculated for the Bay of Biscay show low levels compared to the...

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.

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).

Introduction : Intra-basin fishing is not grasped as well, partly because of a lack of distinction between pure professional fishing units and conchological units and on the other hand because of the large amount of ships. Poorly adapted codification of the equipment found in the basin is also contributing to this lack of information. Studies on the subject do exist, but the elements necessary to publish notices are not always gathered, this is leading to the proposal of a geographical systemic analysis on the basin. The steps that are being taken are complementing the development of the Geographical Information System already in place in the basin since 1993 through DEL at the Arcachon Ifremer as well as the PECOSUDE European study ¿ caractéristiques des...

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.

A methodology based on data filtering to identify reference fleets to account for the abundance of fish species: Application to the Striped red mullet (Mullus surmulletus) in the Bay of Biscay
Provedor de dados: 5

For data-limited stocks (DLS), professional fishing data can be used as a potential source of information, especially in the absence of appropriate scientific survey, to understand abundance evolution under realistic hypothesis on resource catchability. This work focuses on a data-filtering approach, the selected fishing effort must reflect vessel activity that is least dependent on their technical characteristics and as stable as possible over time. The variable of interest is landing by fishing sequence (landing for a given gear, gear mesh, day and ICES statistical rectangle) called LPUE. In order to account for the abundance of the species, it was necessary to consider the discards. The method thus proceeds in 4 steps: (i) focus on LPUE variability and...

Improvement of the fishery knowledge of striped red mullet of the Bay of Biscay
Provedor de dados: 5
Autores: Caill-milly, Nathalie; Lissardy, Muriel; Leaute, Jean-pierre.
Striped red mullet (Mullus surmuletus) belongs to the species for which individualization of stocks is advanced by ICES in western Europe for areas including the Bay of Biscay and the areas bordering the Iberian peninsula. Since 2012, ICES has provided recommendations with regards to this stock. These recommendations are given for two years and are based on an approach adopted by ICES in 2012 in the case of insufficient data for an analytical evaluation (Data Limited Stocks, DLS). For 2013 and 2014, ICES advice consisted in a 20% reduction in catches (average of the last 3 years:- 2009-2011) as a precautionary measure. Since that, no new advice has been formulated, the advice remains the same. Considering the impacts of such measurements on the French...

The striped red mullet (Mullus surmuletus) is a species for which ICES advances individualization of stocks in Western Europe. One of them concerns the Bay of Biscay, the waters bordering the Iberian Peninsula as well as the Celtic Sea, namely striped red mullet in Subareas and Divisions 6, 7a-c, e-k, 8, and 9a (Mur. 27.67a it-k89a). This stock is part of the Data Limited Stocks (DLS) and is currently classified in Category 5 (ICES, 2016); it is a stock for which only landings data are available. Such knowledge is insufficient to apply the ICES MSY approach and the advice rule on fishing possibilities is therefore based on the precautionary approach. For this stock, this approach is applied since 2012. For 2013 and 2014, ICES has recommended reducing...

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 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...

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 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

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.
