It is an intrusive species. It is significantly expanding its territory in the Mediterranean Sea since the invasion began about ten years ago. The lionfish is invading the Mediterranean and nothing seems to stop it.
It is the Pterois species of lionfish. It consolidates its presence in the eastern Mediterranean. Observations are now being extended to colder waters previously thought to be unsuitable for the species. This is what research from Wageningen University says, published in the journal NeoBiota.
They are native to the Indo-Pacific region. The lionfish species Pterois miles and Pterois volitans are considered the most successful invasive fish in marine ecosystems. They drastically affect local fish communities and biodiversity in invaded areas.
Predator that adapts
They are generalist predators and impact ecosystems by extensively preying on local fish. Native prey species do not typically flee from this new predator. “It’s amazing how they can easily adapt to so many different environments,” says lead author Davide Bottacini.
As the largest enclosed sea in the world, the Mediterranean is a unique ecosystem. It is a basin with great biodiversity that is home to more than 11,000 animal species. Some of them are not found anywhere else in the world. Genetic studies revealed that the lionfish found in the Mediterranean originates from the Red Sea. It probably entered through the Suez Canal.
The researchers identified gaps in our understanding of lionfish interactions with Mediterranean ecosystems. They proposed future research directions to address these challenges. This information provides vital knowledge for biodiversity conservation. It will have practical implications for policymakers seeking to design robust and efficient mitigation plans.
Observed invader
Lionfish are invading the Mediterranean, but everyone can help counteract this advance. The study highlights the crucial role of citizen science initiatives in monitoring and reporting lionfish sightings. Provides valuable data that supports ongoing research efforts. Community participation is essential to design effective control measures.
