Ocean fishing: Bottom trawling causes deep-sea biological desertification

Source: Science Daily

A study led by scientists from the Polytechnic University of Marche (Ancona, Italy) involving researchers from the Institute of Marine Sciences (ICM, CSIC) and the Autonomous University of Barcelona (UAB), has determined that fishing trawling causes intensive, long-term biological desertification of the sedimentary seabed ecosystems, diminishing their content in organic carbon and threatening their biodiversity.

 Trawling is the most commonly used extraction methods of sea living resources used around the world, but at the same time, it is also one of the main causes of degradation of the seabed. This fishing practice originated in the second half of the fourteenth century, and in the last thirty years has grown exponentially.
