Background information and definitions
Trawling is a method of fishing that involves pulling a fishing net (trawl) through the water behind one or more boats. Trawl doors are the boards or metal plates (otter boards) which attach to the sides of the net and keep the net open as it is pulled through the water. The trawl doors can be modified, for instance by using smaller otter boards, or securing netting at wing ends, to reduce sediment penetration. This may potentially limit impact on subtidal benthic invertebrates through reduced damage to the seabed (Balash et al. 2016).
