Toxic Pufferfish Invasion Threatens Crete's Fishing Industry

Thursday, 25 June 2026/Source: Google News/1 min read

Poisonous pufferfish, an invasive species originally from the Red Sea and Indian Ocean, have been spreading through Cretan waters in growing numbers, causing serious concern among local fishermen. The silver-cheeked toadfish (Lagocephalus sceleratus) is highly toxic and inedible, and its presence disrupts nets and reduces catches of commercial fish species. Fishermen across the island report increasing encounters, leading to financial losses and frustration within the fishing industry. For tourists, the practical implication is clear: do not handle pufferfish if you spot one on a beach or in shallow water, as their skin, organs, and flesh contain tetrodotoxin, a potentially lethal poison. Swimmers and snorkelers are not generally at risk from contact with water, but should avoid touching any unfamiliar fish. Local seafood markets and restaurants are not affected, as pufferfish are not sold or served in Crete.
