Main Descriptors
Considered a single stock: Yes        Spatial Scale: Sub-Regional
 
 
Habitat and Biology
Depth zone: Shelf (50 m - 200 m).   Vertical distribution: Demersal/Benthic.  


Sole is a nocturnal predator and therefore more susceptible to capture by fisheries at night than in daylight.

Resource Structure
Considered a single stock: Yes
Exploitation
 

The fisheries


Sole is taken in a directed trawl fishery with bycatch of Nephrops, plaice and cod, the main season being in autumn–winter. In addition there is a directed gillnet fishery for sole, mainly in Skagerrak in spring and summer.
Catch distribution Total landings (2011) =551 t, where 92% are landings (43% trawl, 41% gillnets, and 8% unknown) and 8% discards.


Assessment
 
Overall Assessment Results
Figure 6.4.9.1 Sole in Division IIIa and Subdivisions 22–24. Summary of stock assessment (weights in ‘000 tonnes). 95% confidence limits indicated for recruitment, fishing mortality, and spawning-stock biomass. Top right: SSB and F over the years.
Assessment Model

Quality consideration


Sampling of landings is complicated by the small total landings which are dispersed spatially. This affects the quality of the input data. Historically, the assessment has overestimated SSB and underestimated fishing mortality.

Scientific basis

Assessment type Age-based analytical stochastic assessment (SAM).
Input data One survey index (Fisherman-DTU Aqua survey);
  three commercial cpue indices (official logbook trawlers, private logbook trawlers, and gillnetters).
Discards and bycatch Not included in the assessment.
Indicators None.
Other information Benchmark done in 2010 (WKFLAT 2010).


Biological State and Trend
Exploitation rate: Below trigger
Abundance level: At target
