In Research in early July 2026 researchers reported repeated sightings of the invasive lionfish in Montenegro’s Bay of Kotor and highlighted documented the presence rapid expansion of the toxic silver‑cheeked pufferfish (Lagocephalus sceleratus) in the Aegean Sea. Authorities in Greece, Turkey and Cyprus introduced bounties and EU‑funded removal programs to curb the fish, which threatens fisheries, damages nets and can cause severe poisoning. Two weeks later, monitoring showed from the pufferfish had established dense populations throughout Red Sea into the Eastern Mediterranean, with dense populations now recorded from Crete and the Cyclades to Turkey’s and Cyprus’ coasts, with additional reports from Spain, Italy and Israel. Health agencies issued warnings after sting incidents, and scientists linked the rapid expansion to climate change and the Suez Canal opening, underscoring the need for heightened public awareness and coordinated control measures. On 26 July 2026 a fisherman near Heraklion, Crete, captured a 50‑centimetre specimen coasts of Lagocephalus sceleratus. The fish, a Red‑Sea native that entered the Mediterranean via the Suez Canal, carries lethal tetrodotoxin in its liver, ovaries and skin, Turkey, Cyprus, Italy, Spain, France and is prohibited for sale or consumption under Greece. EU law. Its powerful jaws can damage fishing gear and it poses additional ecological regulations ban its sale and economic risks consumption, yet the fish’s tetrodotoxin‑laden organs continue to local fisheries and marine ecosystems, prompting renewed concern among scientists threaten anglers, damage nets and the fishing community. outcompete native species. By 29 July 2026 late July, marine scientists warned that warming Mediterranean waters are waters—projected to rise 1.8‑3.5 °C and, according to newer estimates, up to 6 °C by 2100—are accelerating the pufferfish’s spread, now reaching the coasts of Greece, Italy, France, Spain invasion. The enclosed basin retains heat from fossil‑fuel‑driven warming, creating ideal conditions for several non‑native fish, including lionfish and Cyprus. Researchers rabbitfish, which entered via the Suez Canal. The UN FAO’s General Fisheries Commission for the Mediterranean noted that projected temperature rises of 1.8‑3.5 °C by 2100 could render invasive species have existed for decades but their spread intensified after the early 2000s, coinciding with rising sea permanently unsuitable for many native species. In temperatures. Local fisheries are feeling the eastern basin, impact: up to 93 % of eastern‑basin mollusk populations have disappeared, and invasive species traditional catches are declining sharply, especially in Cyprus, the closest nation to the canal entry point. Scientists such as Ernesto Azzuro of Italy’s National Research Council warn that without natural predators the pufferfish will continue to proliferate, jeopardising marine ecosystems and rabbit fish are outcompeting traditional catches, threatening the livelihoods of coastal fishing livelihoods. communities. The situation underscores the intertwined threats of climate change, invasive species and socioeconomic vulnerability across the Mediterranean region.
