Schematization of shell samples collection, preparation and structural characterization by SEM. (a) Schematic figure of decontaminated WOS and POS collected from adult living C. gigas oysters (Thau lagoon, France). (b,c) Characteristic SEM images of decontaminated WOS (cross-section and top view, scale bar = 30 and 20 μm, respectively). (d,e) Characteristic SEM images of decontaminated POS (cross-section and top view, scale bar = 50 and 12 μm, respectively). (f) Representative photograph of a decontaminated dorsal valve with a dark adductor muscle scar (AMS), obtained from adult C. gigas wasted shells. (g–i) Characteristic SEM images of decontaminated dark AMS (top views, scale bar = 1 and 6 μm).
