Data from: Trophic mechanisms underlying bentho-demersal community recovery in the north-east Atlantic
1. Bottom trawling is considered one of the greatest and most widespread causes of anthropogenic change in shelf seas, with major and prolonged impacts in areas with a long history of exploitation by fisheries such as the North-Atlantic. Here, signs of recovery following the put into force of regula...
