Blue crabs, originally from the western Atlantic Ocean, have invaded several areas of the Italian coast, particularly the northern delta of the Po River. Their rapid multiplication has been linked to climate change or the bottom water of ships, and efforts to control the invasive species through large-scale fishing have been unsuccessful. The blue crab poses a threat to the marine ecosystem and has caused approximately 100 million euros in damage, wiping out shellfish production in northern regions. The Italian government, representing the agricultural and fishing industries, is taking steps to coordinate the fight against the invasive species and reducing its presence in the Adriatic Sea to prevent mass spread.
