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.

The fisheries


Sole is mainly caught in 80 mm beam-trawl fisheries with plaice or in mixed demersal fisheries using otter trawls and gill/trammel nets. There is also a directed fishery during parts of the year by inshore trawlers and netters on the English and French coasts
Catch distribution Total landings (2011) = 4133 t, (38% beam trawls, 44% trammel/gill nets, 16% otter trawls, and 2% other gears)

Assessment Model

Quality consideration


Under-reporting of catches and misreporting of sole into Division VIId from Division VIIe was thought to be significant but this is now less of an issue. However, the assessment has been corrected for this misreporting.
