Boal (written Boal according to the reintegrationist and isolationist writing norms and Bual according to the Occidental Asturian spelling) is a municipality, a civil parish and a town in the Autonomous Community of the Principality of Asturias (Spain). It borders north with El Franco and Coaña, south with Illano, west with Castropol and east with Villayón.
The main way of access to the municipality is the regional road AS-12, which connects Navia with Grandas de Salime. The whole municipality has a population of 1,776 inhabitants, whereas there are about 526 inhabitants in the capital town.
Etymologically, it is usually considered that "Boal" comes either from the Indo-european languages, *bod- (stream, ditch), or from the Latin, bove or *bovale (ox). Although some authors believe that "Boal" could be understood as the expression of an old anthroponym or person name, Bovali (iler) or Baudiliu (adducing the form Baudali), it is common to consider its original meaning either as "terreno frecuentado y apropiado para el pasto del ganado vacuno" ("land frequented and appropriate for the grazing of cattle") or as "corral de bueyes o dehesa boyal" ("corral for oxen or ox pasture"). In fact, Corominas mentions in Aragonese boalage, boalar, "dehesa boyal" ("ox pasture") as derivatives of boal, which would be at the same time a variant of boyal, "perteneciente al buey o al ganado vacuno" ("belonging to ox or to cattle") .
Boal is a name given to several varieties of grape cultivated in Portugal, notably in the production of medium-rich fortified wines from Madeira Island. On many wine labels of Madeira wine, the variety's name is anglicized as Bual. Madeira from Bual is typically less sweet than that from Malmsey, but more sweet than Sercial or Verdelho. The vines are also common in Portugal and Spain, where the fruit is used in the same way for fortified wines.
Most of the Boal grown on Madeira is more fully known as Boal Cachudo (a synonym for the Spanish variety Doña Blanca, though the two may be different grapes), which has been shown by DNA profiling to be identical to the Malvasia Fina grown in the Douro valley.
Buckingham Palace holds 25,000 bottles of wine, the oldest being a bottle of bual from 1815.
Wallago attu (Thai: ปลาเค้าขาว) is a species of catfish in the family Siluridae, or "sheatfishes". The fish is commonly known by its genus name, wallago or 'lanchi'. It is found in large rivers and lakes in much of the Indian Subcontinent and in parts of Southeast Asia. The species can reach 2.4 m (8 feet) total length. It ranges mainly across India, Nepal, Bangladesh and Sri Lanka, but is also found in Thailand, Cambodia, Vietnam and Malaysia, and is also reported from Afghanistan.
This catfish is one of the fish species that has been used as food in Southeast Asia since ancient times.
In Bengal and Assam, it is known as Boal and Borali. In Manipur it is commonly known by its local name "Sareng". In Indonesia and Malaysia, the wallago is known as "Ikan Tapah," and this name is the origin of the name of a Malaysian town, Tapah. In northern India it is known as buari. It is also known as Wallagonia attu, Boal Fish etc. Other names of the Sareng include the Mully Catfish, and Freshwater Shark due to its ferocity; and Helicopter Catfish.
