It is regularly reported that Common bottlenose dolphin Tursiops truncatus is attacking fish nets off Moroccan and Tunisian Mediterranean coasts causing severe damages to fishermen leading to social issues locally. To our knowledge similar cases of Common bottlenose dolphin depredation wasn't reported in other areas.
We wonder what sustainable measures could be implemented to mitigate depredation impacts? certainly other cetaceans species would have depredation impacts on fishing activities elsewhere.

Article A review of interactions between cetaceans and fisheries in the Azores
The depredation caused in the Mediterranean artisanal fisheries by the bottlenose dolphin Tursiops truncatus) is well described in the literature.

One possible mitigation method to this depredation is the use of acoustic pingers (with varying results).

In India, according to Sutaria and al. (2015), humpback dolphins of the genus Sousa, are known to cause damage and depredation of fish catch of certain fishing gears, making them unpopular, along many coastal sites.
