Killer pufferfish devastate Crete's fishing industry, prompting calls for subsidies

Invasive pufferfish, which entered the Mediterranean Sea via the Suez Canal, are causing significant devastation to Crete's fishing industry, leading to calls for urgent government intervention. These fish possess powerful jaws capable of destroying fishing nets and equipment, and their proliferation has led to a sharp decline in commercial fish populations.

Fishermen like Alexis Charalampakis and Giannis Giankakis report extensive damage to their gear, with nets becoming useless after only a few days of use. Lambis Atzarakis highlighted that the sea is now dominated by alien species such as lionfish and pufferfish, with a noticeable absence of desirable commercial fish.

Greek fishers are urging the government to implement an immediate subsidy scheme for catching and removing pufferfish. Marine biologist Nota Peristeraki from the Hellenic Centre for Marine Research (HCMR) stated that the species, identified as Lagocephalus sceleratus, has a substantial impact on coastal fishing, estimating average annual losses of around €8,500 per fishing vessel.

Pufferfish were first observed in Greece in 2005 and have since spread widely. Beyond their economic impact, these fish carry a deadly toxin, tetrodotoxin, concentrated in their organs. Marine biologist Thekla Anastasiou warned that ingesting this toxin can be fatal, causing respiratory paralysis and heart failure, and requires extreme caution in handling and consumption.

In parallel, researchers are exploring methods to neutralize the tetrodotoxin. Chemist Manolis Mandalakis indicated that studies are underway to safely remove the toxin, potentially enabling the fish's biomass to be utilized in lower-risk applications such as fertilizer and compost production. Scientists and fishermen agree that swift action is crucial to protect marine ecosystems and the livelihoods dependent on them.
