Mahi mahi – one more invaluable resident of our seas. It is a particularly important species in our waters, as it preys on young silver-cheeked toadfish – one of the most problematic invasive species that are spreading at an alarming rate in the Greek seas.

It is therefore crucial to recognize that the overfishing of local species such as the Μahi mahi – which act as natural predators of alien species – has been a major factor contributing to the spread of invasive species in our marine ecosystems.

Mahi mahi (Coryphaena hippurus) is among the fastest pelagic fish, capable of reaching speeds of 50–60 km/h. It can grow to over 2 meters in length and weigh up to 40 kilos. Known for its rapid growth, it has a relatively short lifespan of just 4–5 years.

The silver-cheeked toadfish (Lagocephalus sceleratus) is one of the most destructive invasive species in the Mediterranean. Its rapid spread, the presence of the powerful neurotoxin tetrodotoxin in its body – which makes it dangerous to humans and unfit for consumption – along with its harmful effects on marine biodiversity and fisheries, make it a serious threat to ecosystems and local communities.
