Adriatic Sea octopus release targets invasive blue crab
Scientists from the University of Bologna have launched the ‘Octo-Blu’ project to combat the rapid spread of the invasive blue crab in the Adriatic Sea. The project involves releasing approximately 160,000 young octopuses into the sea, as octopuses are natural predators of the crabs.
The blue crab, an invasive species from the North American Atlantic coast, has caused significant ecological and economic damage. In Italy, the impact on the fishing and shellfish industries is estimated at roughly 200 million euros, with specific regions like Emilia-Romagna reporting heavy losses in mussel and clam production.
The threat is expanding across the Adriatic; recent sightings in protected areas near the Lašva Archipelago in Croatia have raised alarms among ecological authorities. Experts link the surge in the crab population to warming sea temperatures and climate change. While the octopus release is a natural biological control method, some local experts remain cautious regarding the crabs' ability to adapt to different water conditions.
