Megrim, Whiff
Cornish sole is a flatfish with a distinctive diamond-shaped body, pale brown upper side, and white underside. Unlike most flatfish, both eyes are positioned on the left side of the head. It has a delicate, flaky texture and a mild, sweet flavour that makes it a prized choice among chefs.
Cornish sole is a demersal species found along sandy and muddy seabeds in deep offshore waters. It is abundant in the western English Channel and Celtic Sea. The fish is mainly landed by Cornish vessels fishing out of ports such as Newlyn and Looe, often as part of mixed trawl fisheries.
Sustainability Rating
Status: Stocks of Cornish sole are currently in a healthy state and not subject to overfishing.
Best Choice: Fish caught using demersal trawl nets by Cornish boats operating in areas where bycatch is reduced, and trawl gear is modified to lessen environmental impact.
Avoid: Fish caught in mixed fisheries with high levels of discards or in areas where stock assessments are poor or absent.
Culinary Uses
Cornish sole is a versatile fish, best served whole or as fillets. Its delicate flavour and fine texture make it suitable for pan-frying, grilling, or baking. Pairs well with buttery, lemon-based sauces or light Mediterranean accompaniments. A popular alternative to more familiar flatfish like Dover sole or lemon sole.
Best Fishing Practices
Demersal trawling with selective gear is the primary method used by Cornish vessels. The use of larger mesh sizes and escape panels helps reduce bycatch and improve sustainability. Landings are monitored under quota and regulated through the EU and UK fisheries management frameworks.
Seasonality
Available throughout the year, with peak landings and quality typically from spring to early autumn.
