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 and between 20-30 cm. Lemon sole may live for about 17 years and can attain lengths of over 60 cm. They spawn in spring and summer, April to August.
