Invasive lionfish likely to become permanent residents in the Mediterranean

An invasive species first identified in the Mediterranean Sea just eight years ago is likely to become a permanent feature of the region, a new study suggests.

First seen off the coast of Cyprus in 2012, lionfish (Pterois miles) are now thriving and well-established in the area and across southern Europe.

However, the increasing densities observed over time—combined with the species' generalist diet and consumption of ecologically and socio-economically important fish—may result in further disruption of an already stressed marine environment.

The scale of spread would suggest the lionfish cannot be eradicated, with scientists writing in the Journal of Fish Biology suggesting the development of a dedicated lionfish industry could help manage the situation and lessen some of the species' negative impacts.
