Disappearing fish: grey seal depredation in a Baltic net fishery (supporting dataset) ...
Grey seals ( Halichoerus grypus ) in the Baltic Sea commonly attempt to steal fish captured in net fisheries. Seal depredation reduces economic yields for small-scale net fishers in a region already highly impacted by the collapse of important fish stocks. Visible damages in looted nets consist of i...

Grey seals ( Halichoerus grypus ) in the Baltic Sea commonly attempt to steal fish captured in net fisheries.
