Abstract The common cockle is a valuable bivalve species inhabiting the Atlantic European coasts. parasite Marteilia cochillia has devastated beds in southern Galician (NW Spain) rias since 2012. Previous data suggested that cockles from Ría de Arousa acquired some resilience to this through natural selection after consecutive annual marteiliosis outbreaks and candidate markers associated with were identified using population genomics transcriptomics approaches. Here, garden experiment was performed naïve stock (from Muros‐Noia) an affected Arousa) test hypothesis. Breeders both stocks used produce seed cohorts at hatchery, which pre‐grown raft (outdoor nursery stage) deployed two shellfish by (growing‐out stage). In beds, showed high prevalence fully depleted short period, while barely evidence of marteiliosis.

Heatwaves are expected to intensify and become more frequent throughout the 21st century, posing significant threats coastal ecosystems socio-economically important species. Shellfisheries based on intertidal shallow subtidal infaunal bivalves such as Ruditapes decussatus, philippinarum, Venerupis corrugata, Cerastoderma edule of socio-economic importance in Europe, particularly Galician Rías Baixas (NW Spain). This study evaluates how future atmospheric heatwaves may compromise thermal dynamics these four commercially Ría de Arousa. Global oceanic climate data from CMIP6 were downscaled using WRF Delft3D-FLOW models. The model was used characterize for period 2025-2099 under SSP2-4.5 SSP5-8.5 pathways, while calculated bottom water temperatures pathway during most intense heatwave. Thermal exposure evaluated a 1D sediment heat transport model. analysis revealed total 88 events projected with an increase frequency, duration, intensity over time, summer months. A temperature estuary's inner areas simulated heatwave, driven by extreme air calm winds. species V. corrugata C. experienced longest high temperatures, linked their shallower burrowing depths lower tolerance, R. decussatus philippinarum remained unaffected heatwave simulated. These findings highlight vulnerability certain bivalve intensifying heatwaves, which could lead greater socioeconomic consequences.
