Population trends. In the last three decades, only isolated specimens have been
caught in stake nets in the Romanian waters (Sulina, Constantsa and Agigea). No
catch for the last five years on the Turkish coast.
Threats. Eutrophication, turbidity in shallow water.
Conservation measures taken. None.
Conservation measures proposed. Reduce eutrophication and pollution by
improving the quality of riverine input. Mitigate pollution in the Bosphorus Strait and
Black Sea. Ban swordfish fisheries in certain periods in the Black Sea. Establish a
special recovery programme in the entire Black Sea.
