Very low risk
Very high risk
The status of plaice in Subarea 4 (North Sea) and Subdivision 20 (Skagerrak) has been scored a very low risk. The spawning stock has been at levels consistent with safe and optimal long term yields since 2011 and has been exploited at a rate consistent with maximum sustainable yield since 2009.
This is because spawning stock biomass is above the MSYBtrigger level (the level above which high optimal term yields are expected) and fishing mortality has been close to the FMSY reference point since 2009, which should result in optimal long term yields.
The management of this stock has been scored a moderate risk.
The stock is assessed annually by ICES, and control measures appear to have contributed to a healthy increase in stock size over the past decade. However, there is some uncertainty as to the effect of the implementation of the Landings Obligation will have on control and accounting for catches because there is a risk of continued undocumented discarding.
The bycatch risk of this fishery has been scored a high risk. This is because bycatch of vulnerable species in the demersal seine net fishery is potentially relatively high (15-39% of catch weight) compared to other fisheries. Demersal seine nets are an active form of fishing gear that have the potential to take relatively high quantities of bycatch of vulnerable species in certain circumstances.
The habitat risk of this fishery has been scored a low risk. This is because demersal seine nets have limited interaction with seabed habitat compared to other fishing activities. Demersal seine nets anchored to the seabed have the potential to cause surface abrasion of biogenic features under certain circumstances. Some spatial management in place to restrict the footprint of this gear on the seabed.
