Abstract

A method of improving conditions for breeding aquatic life in a breeding farm comprising the steps of injecting an ozonated gas into a stream of water to achieve a level of ozonation; adding a reducing chemical species to the stream of water in order to substantially remove a possible content of oxidizing by-products and/or ozone resulting from the step of injecting the ozonated gas; and feeding the stream of water to a breeding basin wherein the reducing chemical species is added to the stream of water in situ and continuously between the step of injecting the ozonated gas and the step of feeding the stream of water into the breeding basin.
