A data-limited assessment is conducted by ICES based on habitat area, estimated burrow density and data from the fishery. LPUE and mean size are used as indicators. The assessment is expected to improve as data-limited methods are improved (ICES, 2012a). Landings and effort data are available from Nephrops-directed fleets, but a change to the French definition of effort has introduced some uncertainty. Other sources of uncertainty stem from a possible underestimation of LPUE and the incompleteness of the time series of discards (ICES, 2012a).

ICES previously advised for this fishery together with the remainder of the Celtic Sea fishery. Advice has been provided separately for Functional unit (FU) 20-21 for the first time in 2012. Based on the data-limited approach, landings are advised to be kept below 2,500 tons in 2013. This was determined based on average historical landings, known habitat area and assumed density of Nephrops, along with the known range of maximum sustainable yield (MSY) harvest rates for other Nephops units in the area. Management measures should be implemented at the FU level (ICES, 2012a).
No reference points are defined (ICES, 2012a).

andings per unit effort (LPUE) series have decreased in recent years, indicating a decrease in abundance, but no reference points are set and stock status is not known. Mean size in landings and discarding rates suggest no major changes in status however (ICES, 2012a).
Harvest rates have recently decreased and are estimated to be within MSY ranges but could be even lower than those estimated (ICES, 2012a).
The stock appeared to be in a stable state for a long period, based on indications from LPUE, mean size and discarding rates. Strong recruitment led to an increase in LPUE in 2008 and 2009, but a decrease has occurred since then (ICES, 2012a).
Landings were stable during the 2000s, with small increases reported in 2002-2003 and 2008-2009, coinciding with lower mean size in landings and potentially due to recruitment increases. Landings fell in 2010 and 2011, possibly due to decreased targeting of Nephrops (ICES, 2012a).
