| Abstract | Seasonal occurrence of skin and gill parasites in fish ponds can substantially affect fish performance by reduced growth and increased mortality and hence the economic returns of aquaculture systems. To minimize loss of fish, preventive and curative water treatments are typically applied by adding sodium chloride and/or formalin into the ponds. This note from the field describes a simple alternative method to improve water quality in a Danish flow through fish farm. Instead of periodic formalin baths/flushes in all ponds, peracetic acid (PAA) was continuously added from a mixing tank to the common water inlet during daytime throughout the spring and summer season. The method was tested on a commercial organic flow through trout farm, and included verification of PAA residuals and distribution in the makeup water, within ponds and in the effluent from the fish farm. PAA was found to be evenly distributed to the ponds, achieved and maintained at concentrations around 0.10-0.15 mg PAA/1 corresponding to aimed values. PAA degraded within the fish ponds and negligible amounts of PAA were measured in the discharge. The economic and environmental feasibility of the applied low practical methods was demonstrated as white spot disease outbreak was absent throughout the season without using any formalin.
