Research on bacterial amendments applied to aquaculture ponds was conducted by Boyd in 1984 and Tucker & Lloyd in 1985. No differences were found between treated ponds and control ponds for inorganic nitrogen, total phosphorus, chemical oxygen demand, biochemical oxygen demand, chlorophyll a, abundance of bacteria and phytoplankton and percentages of blue-green algae. They concluded it is not necessary to add bacteria to ponds because the bacteria are already present.
