The fishery for Lemon sole is generally unmanaged in EU waters and there is no minimum landing size. The exceptions for this are in areas IV and IIa where there is a mixed precautionary total allowable catch (TAC), and in Cornwall where a Minimum Landing Size of 25cm is enforced by local Cornish IFCA byelaw. Choose seine caught fish where possible, as this is currently the most sustainable capture method for the species.
Lemon sole is a widely distributed flatfish which is found in shelf waters of the North Atlantic, from the White Sea and Iceland southward to the Bay of Biscay. Lemon sole appears to prefer sandy and gravelly substrates, living deeper and at higher salinity and lower temperature than plaice or sole. Sexual maturity occurs in males at 3-4 years and at 4-6 years in females. Lemon sole may live for about 17 years and can attain lengths of over 60cm. They spawn in spring and summer, April to August.
There is no formal or analytical assessment of lemon sole in EU waters. The main cause of this is lack of data; specifically data on age, effort, catch per unit effort (CPUE) etc. is required. However, survey information available for the North Sea subarea IV and Divisions IIIa and VIId indicates stable biomass at a high level. Landing data however show a declining long-term trend. ICES advice for 2016 and 2017 is that catches should be no more than 5,655 tonnes. Provided discard rates do not change (30% of the total catch) this implies landings of no more than 3959 tonnes.
Lemon sole is mainly a bycatch species and as such the fishery is currently largely unmanaged. The only management of the fishery is under a combined total allowable catch (TAC) with witch. Scientists are concerned this prevents effective control of single species exploitation rates and could potentially leading to overfishing of either species.
Lemon sole are generally taken as bycatch in mixed fisheries by beam trawlers (32%) and otter trawlers (59%), seine 4% and gillnet 4%. There is no minimum landing size set for lemon sole in EU waters. The size at maturity for the species ranges between 20-30cm, with all fish above 27cm in the North Sea being mature. In the Cornwall Sea Fisheries District, a Minimum Landing Size of 25cm is enforced, which is likely to represent a vast majority of mature fish. Trawling is associated with benthic impact, bycatch and discards.
