Impacts of bottom trawling

Bottom trawling is a human activity involving the extraction of live resources from the seafloor. The impact of this activity on fish and crustacean populations, as well as on the benthic community, is a widely-known and researched fact that is receiving growing interest from the media. However, trawl fishing also has a direct effect on the sediments covering the sea bottom. In this lecture, the speaker will explain the consequences of the daily contact of trawl doors and nets on marine sediments, and how – in a matter of four decades, ever since the industrialisation of fishing – the underwater relief of our seas has undergone significant changes.
