The SYMPA map highlighting in grey the European countries and a North African country represented at the symposium. Coloured dots and lines indicate scientific projects targeting Ruditapes philippinarum (red), R. decussatus (blue), Venerupis corrugata (green), and Polititapes aureus (yellow), either at specific locations (dots) or along broader coastal areas (lines). The numbers above the dot or line refer to the thematic sessions in which the corresponding research was presented. When dots are positioned centrally within a country, they denote projects conducted at a national or fisheries level, without direct field sampling at specific coastal sites.
