Invasive fish species have become a serious issue for fishing communities in the eastern Mediterranean, with Cyprus among the most affected areas. Since the 2010s, lionfish and silver-cheeked toadfish have entered Mediterranean waters from the Red Sea. Marine scientists connect this movement to rising sea temperatures and the expansion of the Suez Canal, which has changed natural sea routes. Researchers warn that these conditions increase pressure on native fish species that support local fisheries. Surveys by fisheries departments show a sharp decline in traditional catch species near Larnaca, a coastal city once known for productive fishing grounds. This decline threatens the economic stability of professional fishermen and raises concerns about long-term food supply in the region.

Current responses focus on controlling invasive populations rather than removing them completely. European programs provide financial incentives for catching toxic silver-cheeked toadfish, which are destroyed to limit population growth. These measures aim to reduce damage to fishing nets and lower financial losses. Another method targets lionfish through organized removal by trained divers in reefs and protected areas. Research indicates that repeated removals can help native species recover. Authorities are also promoting lionfish as a food option after safe preparation. Fisheries experts state that wider acceptance of invasive species as seafood could reduce environmental damage while supporting coastal economies.
