The Albufera, La Albufera or L'Albufera de València (, meaning "lagoon" in Valencian, from Arabic al-buhayra, "small sea"), is a freshwater lagoon and estuary on the Gulf of Valencia coast of the Valencian Community in eastern Spain. It is the main portion of the Parc Natural de l'Albufera de València ("Valencian Albufera Natural Park"), with a surface area of . The natural biodiversity of the nature reserve allows a great variety of flora and fauna to thrive and be observed year-round. Though once a saltwater lagoon, dilution due to irrigation and canals draining into the estuary and the sand bars increasing in size had converted it to freshwater by the seventeenth century. Geography The Valencian Albufera Nature Park and lagoon lies just south of Valencia, in the municipal areas of 13 towns and four (former towns) adjoined to the capital city, these in turn lying within four comarques or counties, namely, in Horta Sud: Albal, Alfafar, Beniparrell, Catarroja, Massanassa, Sedaví and Silla; in Ribera Baixa: Albalat de la Ribera, Cullera, Sollana, Sueca and El Mareny de Barraquetes; in Ribera Alta: Algemesí; and in the County of Valencia and greater metropolitan area of València, in the of Pinedo, El Palmar, El Saler and El Perellonet. Its proximity to the capital city of the Valencian Land and easy access facilitate nature experiences and birdwatching. Since 1990, the Valencian Albufera Nature Reserve has been included as a Ramsar Site in the list of wetlands of international importance for birds, established in the Ramsar Convention of 1971. Since 1991 the Parc Natural de l'Albufera de València has also been included in the Special Protection Areas (Zepa in Spanish). Fishing The most important human use of the lagoon has traditionally been and continues to be fishing. History From prehistoric times the rich fishing has attracted people specializing in this activity there. Fishing was legally recognised in year 1250, when regulations were laid down for the El Palmar Fishing Association (residents of the Valencia extramural parish of Russafa who settled permanently on the island of El Palmar to work more conveniently) and which would then be applied to the fisheries of Silla and Catarroja. Present day Until the lagoon's catchment area started to become industrialised, fishing generated substantial profits, as the clean waters of the lake provided a great diversity and abundance of fish ("gambeta", "petxinot", eels, bass, etc.). At present, catches of bass and eels
