Original provider: Giuseppe Notarbartolo di Sciara, Tethys Research Institute Dataset credits: Tethys Research Institute Abstract: The giant devil ray <i>Mobula mobular</i>, the only Mediterranean mobulid, is subject to mortality caused by directed and accidental captures in fisheries throughout the region. Whilst the combination of human impacts, limited range and a low reproductive potential is not inconsistent with its endangered listing, there are insufficient data to enable a quantitative assessment of trends. Without this, it is difficult to assess and prioritise threats and develop effective conservation actions.

Within the "Support MSFD implementation in the Black Sea through establishing a regional monitoring system of cetaceans (D1) and noise monitoring (D11) for achieving GES", financed by European Commission - No. 110661/2018/794677/SUB/ENV.C2, a dedicated aerial survey for marine mammals using distance line transect methods was performed in 2019 in territorial and EEZs of the six Black Sea riparian countries.
