Important threats. In the past, commercial killing was the main human activity affected the population, although a share of bottlenose dolphins in catches was usually less than common dolphins and harbour porpoises. Nowadays, the most important man-made threats are presented by habitat degradation, disturbance and incidental capture in fishing gear. Since the mid 1960s hundreds of animals were taken alive in the USSR and Romania for military, commercial and scientific needs. The Russian Federation and Ukraine are continuing that practice in their waters. Natural diseases also play certain role in the limitation of Black Sea bottlenose dolphins abundance.
