Invasive species population surging in the Mediterranean Sea

A new report from the Cyprus Academy of Sciences, Letters and Arts reveals a rapid increase in non-indigenous species within the Mediterranean Sea. Research involving scientists from 11 countries indicates that over 1,000 invasive species now inhabit these waters, representing a significant rise from the fewer than 800 recorded between 2012 and 2017 by the European Environment Agency. According to the findings, a new species enters the Mediterranean approximately every two weeks.

This ecological shift is primarily driven by rising sea temperatures and the expanded Suez Canal, which provides a gateway for tropical marine life from the Red Sea and beyond. These newcomers are actively displacing native species and fundamentally altering local food chains. Local efforts, such as those involving fishermen in Cyprus who use experimental traps to capture and control populations of invasive species like the lionfish, are currently being implemented to monitor and mitigate the spread of these organisms. The data underscores an ongoing transformation of Mediterranean marine ecosystems that necessitates further scientific intervention and coordinated management.
