Invasive fish species are causing problems for fishing areas in the eastern Mediterranean, especially around Cyprus. Since the 2010s, fish such as lionfish and silver-cheeked toadfish have entered the Mediterranean Sea from the Red Sea. Scientists explain that warmer sea temperatures and the expansion of the Suez Canal have made this movement easier. Marine experts report that native fish populations are decreasing as a result. Fishing surveys show fewer traditional fish near Larnaca, a coastal city once known for strong fishing activity. This change has reduced catches and created financial problems for professional fishermen.

Authorities are working to control the spread of these invasive fish. European programs pay fishermen to catch toxic silver-cheeked toadfish, which cannot be eaten and damage fishing nets. Another effort involves trained divers removing lionfish from reefs and protected waters. Studies show that repeated removal can help protect native fish species. A recent plan also promotes lionfish as a safe food after proper preparation. Officials say this approach may reduce environmental harm and support local fishing communities.
