Abstract The maintenance of stocks estuarine species strongly depends on the ability to cope with environmental stress. In NW Spain, commercial clam beds, which are usually co-occupied by seagrass Zostera noltei, often exposed reduced salinity caused intense rainfalls. Our goals were evaluate effects low events both juvenile clams and Z. including their interactions. A mesocosm experiment was performed simulate three decreases (35–35, 25–10, 20–5), several indicators performance measured after 3 6 days exposure again a recovery period 4 days. No differences observed in non-native Ruditapes philippinarum, while oxygen consumption, clearance rate growth decreased significantly native R. decussatus Venerupis corrugata response noltei did not vary exposure, except sucrose content, decreased. Moreover, buffered from fluctuations short term, although interactions weak. species-specific sensitivity should be major concern future management plans for shellfish beds context climate change.

Bivalve populations are prone to change due sudden or gradual alteration in the natural environment and anthropogenic interference. Fisheries environmental managers therefore interested long-term trends disentangling human influences, assisting them conservation efforts management of bivalve stocks. Here, 64 monitoring reports covering a 50-year period from 1958 2009 cockles Cerastoderma edule (Linnaeus, 1758) South Wales, UK, were scrutinised for data on recruitment, growth mortality. Changes these population parameters related modernisation wastewater treatment 1997, weather climate variables (temperature, sun hours, air frost days, NAO) numbers estuary. Recruitment as well mortalities high during first last decade study, variation was significantly linked total number population. Cockle sizes all cohorts overall biomass declined late 1990s. Modernisation with downward trend, suggesting that changed nutrient regime estuary may have resulted reduced food provision cockles. The average size newly settled their mortality: smaller recruits higher study indicated link between 1997 diminishing cockle shortened life span. Survey methods profoundly after 2009, it is recommended develop conversion factors pre- post-2009 survey methods. This would allow an extension timeline deeper insight into impact recovery
