Stock status

2 of 5
Low risk

Nephrops in Fladen Ground, FU7 has been scored a low risk. This is because the stock is at safe levels and is under exploited. 

Stock levels have been increasing since 2016 and are now well above MSYBtrigger, which is the level associated with sustainable harvesting. Harvest rates have been on a decreasing trend since 2009 and are currently well below levels associated with maximum sustainable yield. 

Management

2 of 5
Low risk

Nephrops in Fladen Ground, FU7 has been scored a low risk. The functional unit (stock) is assessed annually by ICES. Although the TAC is set for the North Sea as a whole, which could lead to uncontrolled increases in fishing effort on individual functional units, there are safeguards under the Multi Annual Plan for the management of North Sea fisheries to avoid overexploitation of these individual functional units.  

Surveillance is generally effective with adequate enforcement and compliance. 

Bycatch

5 of 5
Very high risk

The bycatch risk of this fishery are scored very high risk. This is because the bycatch and reported discard rates are high (>50%) in Nephrops trawls due to the small cod end mesh requirements of the target species.  However, measures to reduce bycatch and discards in these fisheries have been the subject of much research over the years, resulting in technical measures which improve selectivity, which in turn have been implemented as a statutory requirement.  Further measures, such as modified trawl designs, have been implemented on a non-statutory basis.   Furthermore, the cod recovery plan has been implemented in this area and this is expected to have had an influence on the discarding levels in North Sea demersal fisheries and the incoming EU landings obligation is also intended to reduce discarding.

Habitat

3 of 5
Moderate risk

The habitat risk of this fishery has been scored a moderate risk. This is because, with in the core area of this fishery there are vulnerable marine habitats identified and currently there is some spatial management to avoid trawling affecting these habitats.   However, there remains some uncertainties about the location of some sensitive seabed habitats so these remain at risk.
