Brackishwater Aquaculture in Acid Sulfate Soils of Sri Lanka
Abstract:
New and 4-year-old (maintained) ponds in acid sulfate soils of coastal swamps of Sri Lanka were compared. Production of shrimp (Penaeus indicus) and fish (Etroplus suratensis and Chanos chanos) was lower in the new ponds than in the old ponds by a factor of 10. The pH of the water averaged 4.2 in new ponds, 6.1 in old ponds. Acetate soluble sulfates were high: 4,510 and 3,142 mg•kg-1 in new and old ponds, respectively.
