Impacts of Bottom Trawling and Litter on the Seabed in Norwegian Waters [PDF]
Frontiers in Marine Science, 2018 Bottom trawling and seabed littering are two serious threats to seabed integrity. We present an overview of the distribution of seabed litter and bottom trawling in Norwegian waters (the Norwegian Sea and the southern Barents Sea). Vessel Monitoring System (VMS) records and trawl marks (TM) on the seabed were used as indicators of pressure and impact ...

The value of bottom trawling in Europe
Ocean & Coastal ManagementAbstract Commercial bottom trawl and dredge fisheries are active across much of Europe, and their geographic footprint is extensive. More than half of seabed area is trawled every year in some parts of Europe. But these fisheries remain contentious; significant ecological and economic damages have been well documented. Yet, they remain a source

The 'W' prawn-trawl with emphasised drag-force transfer to its centre line to reduce overall system drag. [PDF]
PLoS ONE, 2015 For prawn trawling systems, drag reduction is a high priority as the trawling process is energy intensive. Large benefits have occurred through the use of multiple-net rigs and thin twine in the netting.
