The stock level for eastern Channel sole is now estimated to be too low although fishing pressure is at a sustainable level. To increase the sustainability of the fish you eat from this area, choose sole from the Hastings Fleet trammel net fishery which is certified as an environmentally responsible fishery by the Marine Stewardship Council. Avoid eating immature sole (less than 30cm) and fresh (not previously frozen) fish caught during the breeding season (April-June).
Sole is a right-eyed flatfish (eyes on the right hand side of the body) and belongs to the family of flatfishes known as Soleidae. It spawns in spring and early summer in shallow coastal water, from April to June in the southern North Sea, from May-June off the coast of Ireland and southern England, and as early as February in the Mediterranean. Common sole become sexually mature at 3-5 years, when 25-35cm long, the males being somewhat smaller than the females. It can attain lengths of 60-70cm and weigh 3kg.The maximum reported age is 26 years. Sole is a nocturnal predator and therefore more susceptible to capture by fisheries at night than in daylight.

The spawning-stock biomass (SSB) has been fluctuating without trend since the 1980s, but has decreased and is now around Blim. Fishing mortality (F) has been decreasing since 2014 and is below FMSY in 2017. Recruitment has been fluctuating without trend, and there has been no strong recruitment since 2011.
ICES assesses that fishing pressure on the stock is below FMSY, Fpa, and Flim; and spawning-stock size is below MSY Btrigger and between Bpa and Blim.
ICES advises that when the MSY approach is applied, catches in 2019 should be no more than 2571 tonnes, a third lower than advised for catches in 2018..

There is a directed fishery for sole during parts of the year by inshore trawlers and netters on the English and French coasts. Trammel nets are a wall of net divided into three layers. An inner fine-meshed net is sandwiched between two outer, larger meshed nets. The net is anchored at the base and floated by the headline, allowing it to hang vertically. The inner net is looser than the outer ones, ensuring that the fish become entangled within it. This is a method with little or no impact on the seabed but it can be associated with bycatch. Fish caught in trammel nets are often very good quality as they are not damaged by the capture process. Look for fisheries with large mesh net that select for sole at or above 30cm, the size at which they mature. Minimum landing size for sole in EU waters is 24cm. For trammel nets the minimum mesh size is 100 mm.
