The toxic silver-cheeked pufferfish (Lagocephalus sceleratus) continues to expand across the Mediterranean, driven by rising sea temperatures and Lessepsian migration via the Suez Canal. Originally from the Red Sea, the species has established dense populations in the Aegean, particularly around Crete, Aegean and has spread to Turkey, Cyprus, Egypt, Lebanon, Israel, Syria, Libya, Tunisia, Malta, the Adriatic, Italy, and Gibraltar, with sightings moving toward French Croatia and Spanish waters. the Western Mediterranean. The invasion poses significant ecological and economic risks. The pufferfish is a voracious predator of commercial cephalopods, such as squid, cuttlefish, and octopus, threatening local fisheries. It also causes damage to fishing nets. nets and equipment. To combat the spread, Greek officials have introduced a bounty of €5.33 per kilogram for caught pufferfish, with similar incentive schemes in Turkey and EU-funded programs in Cyprus. Public health remains a critical concern due to tetrodotoxin, which is lethal if consumed and survives cooking. A review of incidents from 2004 to 2023 recorded at least 170 poisoning cases (27 fatal) and 28 bite injuries. In response to reports of the fish biting swimmers, floating barriers have been installed in Greece. Marine experts have recently warned of a broader increase in poisonous and invasive species along Turkish coasts over the last 20 years. Beyond the pufferfish, experts highlighted risks from lionfish, long-spined sea urchins, striped catfish, and boxfish. Regarding the pufferfish, specialists Experts emphasize that both the meat and skin are toxic, and contact with the skin can cause poisoning through open wounds. Additionally, while lionfish meat may be edible, their fins contain poisonous spines. Health authorities and biologists stress the need for caution, advising swimmers In response to avoid rocky zones and reports of the public fish biting swimmers, floating barriers have been installed in Greece. In an effort to avoid consuming unidentified address the biological impact, researchers at the National Technical University of Athens are investigating whether the fish species. can be repurposed for the circular bioeconomy. Studies are examining if components like the flesh, skin, and bones can provide valuable compounds such as collagen, omega-3 fatty acids, or tetrodotoxin for potential experimental cosmetic formulations.
