Description & Characteristics
The Cornish Sole (Lepidorhombus whiffiagonis) is a species of flatfish in the Scophthalmidae family, found mainly in the eastern Atlantic Ocean. It is considered an important commercial food fish, particularly in Europe.
The Cornish Sole has a broad, oval-shaped body and can reach sizes up to 72 cm (28 inches) long. Its upper surface is greyish-brown with small dark spots, while its underside is white or yellowish. Its eyes are on the left side of its head, giving it camouflage when lying on the seafloor.
The Cornish Sole has two fins running along its body. The first run along its spine contains 80-90 soft rays, while the second fin runs along its belly and contains approximately 50 soft rays. It also has two wide pectoral fins that help it move around on the seafloor.
Its most distinguishing feature is its three pairs of barbels near its mouth, which the fish use to detect food sources in murky waters.
Habitat And Distribution
The Cornish Sole is an ocean-dwelling species with a wide distribution worldwide. It is found in the Northern Atlantic and Pacific Oceans and other parts of the world, such as the coasts of South America and Africa.
Its habitat consists of mudflats, sandy areas, and shallow waters near coastal regions. This flatfish has adapted to live in both saltwater and brackish estuaries.
As its name would suggest, this fish lives mainly on the bottom of the ocean floor, preferring to stay close to rocks so it can hide from predators. Its camouflage colouration helps it blend in with its surroundings and remain unseen by potential predators.
While it typically stays within a few meters of the seafloor, it may venture into shallower water if needed for protection or food. The depth at which it is most commonly found ranges from 10-50 meters deep in warm subtropical waters.
Cornish Sole’s Diet
Its diet consists primarily of small crustaceans and molluscs, which it finds by scouring the ocean floor with its protrusible mouth. It has a highly specialised hunting technique: it moves along the seabed with its eyes pointing upward and then rapidly sucks up prey when it detects them.
To capture such prey, Cornish sole has adapted to possess an array of features such as their wide head and sizeable protrusible mouth with bony plates at the posterior end to help them locate food on the seabed. They also have a pair of sensory organs called barbells located near their mouths, aiding them in detecting prey even in total darkness. Additionally, their flattened shape allows for swift movement over sand or mud without much effort.
The abundance of these features makes Cornish sole highly efficient hunters in their environment, allowing them to effectively capture their desired prey and complete their intricate cycle of life. From this perspective, these fish, indeed, are masters of adaptation who have learned how to thrive within their habitat through evolution and natural selection.
Life Cycle Of Cornish Sole
The Cornish Sole is one of the most iconic fish in the North Atlantic Ocean. This flatfish lives up to 15 years and averages 30-50 cm in length.
The life cycle of this species consists of several distinct stages – spawning, larval development, juvenile growth, and maturity.
Spawning occurs in late spring or early summer when the female Cornish Sole lays its eggs in sheltered coastal areas from depths of 10–20 m. After two weeks, the eggs hatch into larvae, which undergo metamorphosis into juvenile fish.
Juvenile Cornish Soles inhabit shallow waters close to shore during their early life stages and feed on small crustaceans like shrimps and crabs. As they grow older, they move further out to sea, eventually reaching maturity at around two years old. Once mature, they feed mainly on larger crustaceans like lobsters, cuttlefish and squid.
After reaching maturity, Cornish Soles will typically remain in the same area for most of their adult lives. They spawn at the exact location yearly, making them highly vulnerable to overfishing in certain areas, as their population can quickly be depleted if not managed responsibly. This has resulted in some stocks being declared endangered due to unsustainable fishing practices; however, efforts are being made to protect these stocks by implementing catch limits and other management measures such as closed seasons and gear restrictions.
Cornish Sole Fisheries
In some parts of its range, such as off the South West coast of England, it is still targeted in high numbers by commercial fleets in Cornwall. In other areas, such as off the coast of North America and Japan, it is mainly landed as bycatch.
In recent years there has been an increasing trend toward sustainable fishing practices for Cornish sole. This includes reducing bycatch through improved gear selectivity and using more selective harvesting methods such as hand lining or jigging.
In addition, there have been improvements made to fish stock assessment models to understand population dynamics better and ensure that sustainable harvest levels are maintained.
Furthermore, many countries have adopted catch limits or area-based management measures for this species to ensure its long-term conservation and viability.
Sustainability
The sustainability of Cornish sole is an important consideration when it comes to the long-term viability of the species. A healthy and sustainable fishery ensures that the species can continue to be harvested, providing an important food source for local communities. With this in mind, several measures have been taken to ensure the sustainability of Cornish sole fisheries by The Cornish Fish Producers Organisation and other environmental organisations.
First, catch limits have been set for commercial and recreational fisheries to limit overfishing and allow populations time to recover from harvesting. Additionally, regulations have been established to control fishing gear used in Cornish sole fisheries, such as trawls and nets.
These restrictions are designed to reduce bycatch and unnecessary environmental damage caused by fishing practices. Furthermore, the introduction of closed areas has allowed some parts of the population to remain undisturbed, allowing them to reproduce and replenish stocks in other regions.
Overall, these measures have resulted in a more sustainable fishery that has significantly reduced the overexploitation of Cornish sole populations.

Processing Cornish Soles
Whole fish for sale
Despite the Cornish sole’s excellence, it is frequently compared to the Dover sole. Whole fish are sold with no head or guts, making them ready for cooking.
Fish prepared in-house has been cleaned, gutted, and scaled, ready for baking, grilling, or pan-frying. When fish is cooked properly, it stays incredibly juicy.
Sold as fillets
There are many fish cuts, but the filet is the most common. Fillets are created by taking off the bone and then pin-boning them. Cut fish fillets into more significant portions that can later be processed.
The flesh of the Mergim sole is soft, and the skin is thin, allowing it to be fried quickly until crispy. Large megrim fillets are standard.
How To Prepare Cornish Soles
Preparing Cornish sole is a culinary adventure akin to an artist mixing paint on a canvas. It is a delightful process that can yield delicious results with the right ingredients and attention to detail.
