The Mediterranean Sea is facing a growing threat from invasive alien species, which are outcompeting native fish populations and disrupting the delicate balance of marine ecosystems. In the southern Dodecanese islands and Crete, fishermen are catching fewer fish, with most of them being non-native species.
Experts warn that the increasing presence of invasive species, such as the silver-cheeked toadfish, poses a significant threat to marine biodiversity and fisheries. Despite this, the Greek state has failed to take action, unlike neighboring countries like Cyprus, which have implemented measures to combat the issue.
According to Stelios Katsanevakis, a professor of marine sciences at the University of the Aegean, there are over 1,000 alien species in the Mediterranean, with 650 of them having established viable populations. Of these, around 120 are considered invasive and pose a threat to marine biodiversity.
The problem is ongoing, with six to seven new species being added every year. Katsanevakis estimates that around 10% of these new species are likely to cause trouble. The lack of action from the Greek state is concerning, especially given the numerous scientific proposals and initiatives that have been put forward to address the issue.
