Ozone treatment in a closed‐recirculating water system significantly improved survival of freshwater prawn larvae. Post‐larval production in several rearing trials varied from 6–17.5 prawns per liter of water. This improvement over the mean of 4.1 larvae/liter achieved in the non‐ozonated controls might be due to the positive effects of ozone on the water quality. For instance, it can accelerate the conversion of nitrogenous wastes into the stable forms and it can serve as a prophylactic chemical with no retaining effect.
