The invasion of blue crabs could pose a threat to the Italian economy, as they destroy oysters, mussels, fish, and even attack people. This is particularly affecting the seafood industry with 1,500 enterprises in the Veneto region suffering and local restaurants struggling to find seafood for their menus. The authorities have allocated 3 million euros to combat the problem, but fishermen who catch the crabs for sale are proving to be the most effective solution so far.
