The context<\/h2><\/div>

In the Mediterranean, hundreds of non-indigenous marine species<\/strong> are quietly settling beneath the surface. While most go unnoticed, others, such as the blue crab, are already reshaping<\/strong> our coastal ecosystems. Facing this biological challenge<\/strong>, the cross-border ALIEN-OCCICAT<\/strong> project was launched to build a shared monitoring<\/strong> network<\/strong> between Occitanie and Catalonia. Such an initiative cannot succeed without your help: divers, fishermen, beachgoers, sailors, and snorkellers, help us spot<\/strong> these new arrivals before they establish themselves permanently.<\/p>\n<\/div>

Explore our species fact sheets<\/strong><\/a> to learn how to identify them, and discover how you can contribute<\/strong><\/a> today to the detection and monitoring of Non-Indigenous Species.<\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div>
