CRUSTACEA, AND ESPECIALLY SHRIMPS ARE FARMED IN PONDS, WHICH CAN BECOME CONTAMINATED WITH PATHOGENIC BACTERIA, AND IN WHICH PREDATORY FISH CAN CONSUME A SIGNIFICANT PROPORTION OF THE SHRIMPS IF NOT CONTROLLED. THE PONDS DESIRABLY SHOULD CONTAIN A CONTROLLED LEVEL OF PHYTOPLANKTON. SUCH PONDS CAN BE TREATED WITH DILUTE PERACID SUCH AS PERACETIC ACID AT A CONCENTRATION THAT IS SIGNIFICANTLY BELOW THE CONCENTRATION WHICH IS LETHAL TO THE SHRIMPS IN ORDER TO CONTROL PHYTOPLANKTON AND/OR PATHOGENIC BACTERIA AND TO KILL THE FISH. THE PERACID IS PREFERABLY SELECTED IN THE RANGE OF FROM ABOUT 0.5 TO ABOUT 5 MG/L PERACETIC ACID. |
