Aquaculture production in Thailand is broadly divided into two categories: (1) inland freshwater aquaculture and (2) coastal or marine aquaculture [25]. All freshwater ultimately comes from precipitation of atmospheric water vapor, reaching inland lakes, rivers, and groundwater bodies directly, or after melting of snow or ice. Since 2004, freshwater aquaculture production has doubled; but, because the intensity of production has increased, the global pond area in 2016 was estimated to only be around 11 million ha. 18 January 2016, at 12:00am.
