Pond fish culture in Czechoslovakia has nearly 900 years of tradition. The first fish ponds date back to the 10th and the 11th centuries in Bohemia and Moravia. The greatest development was in the 16th century when complex fish farms were built in Bohemia and Moravia and water surface area was estimated to be more than 120,000 ha (296,400 acres). During the 18th and 19th centuries, cultivation became more intensive, resulting in a reduction of water area by 50% with converted ponds being used for pastures and crops. After this time, pond area gradually declined so that by 1933 there were only about 42,000 ha (103,820 acres) in Bohemia and 5915 ha (14,610 acres) in Moravia. Following this period came the first state fish farms.
