Management

Low risk

Nephrops in Division VIIf,g (Celtic Sea, FU22; The Smalls), has been scored a low risk. The stock is assessed annually by ICES. The Total Allowable Catch (TAC) is set for ICES Subarea 7 as a whole, which could lead to increases in fishing effort on individual functional units. However, there are safeguards under the Multi Annual Plan for the management of Western Waters fisheries to avoid overexploitation of individual functional units.

Surveillance is generally effective with adequate enforcement and compliance. 

Bycatch

4 of 5
High risk

The bycatch risk of this fishery has been scored high risk. This is because the overall bycatch and discard rates are high in Nephrops trawls due to the small cod end mesh requirements of the target species and due to relatively high discard rates of Nephrops themselves. There is also a moderate risk to Protected, Endangered and Threatened (PET) species; these are likely to be impacted by the fishery but have high survival rates.  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 statutory requirements.
