Stock status

1 of 5
Very low risk

The megrim stock in the northern North Sea and west of Scotland waters has been scored as very low risk.  This is because fishing mortality is well below Fmsy and estimated biomass is well above Bmsy.  Trends indicate that fishing mortality has been and is still decreasing, whilst biomass has been on the increase since 2005.

Management

2 of 5
Low risk

The management of megrim in the northern North Sea and West of Scotland has been scored as low risk. This is because the stock is assessed annually using the MSY approach and enforcement is considered adequate in the fishery.

Bycatch

4 of 5
High risk

The bycatch risk for this fishery has been assessed as high risk. Demersal otter trawling is known to have a high rate of bycatch of non-target species.  Some of these species are also non-commercial or protected and there is little information available as to the extent of this side of discards.

Habitat

4 of 5
High risk

The seabed effects of the fishery are scored as high risk because demersal otter trawling has the potential to severely damage benthic habitats.  Demersal otter trawling is known to have an adverse impact on areas that have been trawled, however this may be somewhat negated by the clearly defined fishing grounds as much of the seafloor remains relatively undisturbed by intense fishing activity.
