| On French coast, Manila clam is a bivalve subject of a large activity recreational and professional hand harvest. Two species are represented in France, European Manila clam Ruditapes decussatus (native) and Japanese Manila clam Ruditapes philippinarum (introduced). Predominance of this last species (more than 90 % of number and biomass), earn them the status of invasive species. Contrary to Arcachon bay, Pont l’Abbé River or Morbihan bay, an estimation campaign of Manila clams stock on Marennes-Oléron bay had never been carried out. The objective of this study: estimate, in number and biomass, the Manila clams stock of two areas. The first affect recreational hand harvest, on Saint-Trojan shore (0.8 km²) whereas the second scopes professional hand... |

| La vénériculture a connu un essor important dans les années 1980, grâce à la mise en place de techniques de reproduction et de grossissement pour la palourde croisée japonaise. Cependant, la maladie de l'anneau brun, qui a été la cause de fortes mortalités, ainsi que la concurrence intemationale provoquant une chute des cours de la palourde, ont été à l'origine du coup d'arrêt de la vénériculture dès la fin des années 80. A l 'heure actuelle, la vénériculture reste une activité marginale. Néanmoins, le long des côtes françaises, et notamment au niveau du bassin de Marennes-Oléron, des populations de palourdes se sont développées à l'état naturel. Cela entraîne une activité de pêche professionnelle et touristique relativement importante. Dans le but de... |

| Aim To investigate some of the environmental variables underpinning the past and present distribution of an ecosystem engineer near its poleward range edge. Location >500 locations spanning >7,400 km around Ireland. Methods We collated past and present distribution records on a known climate change indicator, the reef‐forming worm Sabellaria alveolata (Linnaeus, 1767) in a biogeographic boundary region over 182 years (1836–2018). This included repeat sampling of 60 locations in the cooler 1950s and again in the warmer 2000s and 2010s. Using species distribution modelling, we identified some of the environmental drivers that likely underpin S. alveolata distribution towards the leading edge of its biogeographical range in Ireland. Results Through... |
