Sole is a fish belonging to several families. Generally speaking, they are members of the family Soleidae, but, outside Europe, the name sole is also applied to various other similar flatfish, especially other members of the sole suborder Soleoidei as well as members of the flounder family. In European cookery, there are several species which may be considered true soles, but the common or Dover sole Solea solea, often simply called the sole, is the most esteemed and most widely available.
Etymology of the wordEdit
The word sole in English, سول پیس in Urdu, French and Italian comes from its resemblance to a sandal, Latin solea. In other languages, it is named for the tongue, e.g. Greek: γλώσσα, German: Seezunge, Dutch: zeetong or tong, Hungarian: nyelvhal, Spanish: lenguado, Arabic: إلسان الثور Elsan Eth-thawr (for the common sole) literally meaning 'the tongue of ox' in Qosbawi accent.
A partial list of common names for species referred to as sole include:
- In the sole suborder Soleoidei:
- Several species of righteye flounder in the family Pleuronectidae, including the lemon sole, the Pacific Dover sole, and the petrale sole.
The true sole, Solea solea, is sufficiently distributed that it is not considered a threatened species; however, overfishing in Europe has produced severely diminished populations, with declining catches in many regions. For example, the western English Channel and Irish Sea sole fisheries face potential collapse according to data in the UK Biodiversity Action Plan.
Sole, along with the other major bottom-feeding fish in the North Sea such as cod, monkfish, and plaice, is listed by the ICES as "outside safe biological limits." Moreover, they are growing less quickly now and are rarely older than six years, although they can reach forty. World stocks of large predatory fish and large ground fish such as sole and flounder were estimated in 2003 to be only about 10% of pre-industrial levels. According to the World Wildlife Fund in 2006, "of the nine sole stocks, seven are overfished with the status of the remaining two unknown."
In 2010, Greenpeace International has added the common sole to its seafood red list. "The Greenpeace International seafood red list is a list of fish that are commonly sold in supermarkets around the world, and which have a very high risk of being sourced from unsustainable fisheries."
