The Mediterranean is facing a dramatic transformation due to the invasion of non-indigenous species. A new species is estimated to enter the Mediterranean every two weeks, according to a recent survey. This has resulted in the displacement of native species, disruption of food chains, and a threat to fisheries.

Impact of Invasive Species

The lionfish, a venomous species, has no known predator in the Mediterranean and has a voracious appetite for native fish and crustaceans. Other invasive species, such as the rabbitfish and the Lagocephalus pufferfish, are also disrupting the ecosystem. The rabbitfish grazes heavily on algae, creating barren areas underwater, while the Lagocephalus pufferfish attacks other fish and is associated with reports of reduced octopus catches.

Scientists are looking for ways to adapt to the invasion of these species. One option is to get consumers used to eating new types of fish, such as the lionfish, which is safe to consume once the spines are removed. Markets are emerging in Lebanon and Turkey, while Atlantic blue crabs have found customers in Tunisia.

Efforts to Control Invasive Species

Greek and Cypriot authorities have offered fishermen bounties on pufferfish hauls. Scientists are also testing selective traps designed to attract lionfish and blue crabs while allowing other species to escape. Additionally, researchers are exploring possible uses for alien species in cosmetics, food supplements, leather products, and pain relief.
