Summary:

Demersal trawl gear used to catch Greenland halibut (Reinhardtius hippoglossoides) in west Greenland. A towed vide sled recorded trawling impacts on seafloor fauna. Trawling effort was significantly linked with community composition, with a negative association between trawling effort and abundance of some taxa, including some vulnerable marine ecosystem (VME) indicator species, including a regionally rare species (Halipteris finmarchica).
