| La Directive Cadre sur l’Eau 2000/60/CE établit un nouveau cadre pour une politique communautaire dans le domaine de l’eau. Elle fixe comme objectif général d’atteindre, à l’horizon 2015, un bon état écologique et chimique des masses d’eau souterraines et de surface, ces dernières incluant les eaux côtières (MEC) et les eaux de transition (MET). Dans ce cadre, un certain nombre d'éléments de qualité sont suivis, dont l'élément de qualité "Angiospermes" dans les masses d'eau où les herbiers de zostères sont présents. Ce rapport contient les résultats du suivi mis en oeuvre entre 2007 et 2013 et son classement écologique au sens de la DCE pour cet élément de qualité dans la masse d'eau « Lac d’Hossegor ». |

| 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. |

| 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 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... |
