The use of oxygen in fish farming, whether in ponds or floating cages, offers multiple benefits essential for improving productivity and preventing mass mortalities. In both ponds and culture cages, a higher concentration of dissolved oxygen in the water is essential as it improves fish appetite, promotes feed conversion and reduces stress, which contributes to healthy growth and efficient production in aquaculture.

Rearing fish in oceanic waters presents challenges, such as the need to keep fish confined in cages and oceanographic phenomena that can affect the availability of dissolved oxygen. These phenomena can lead to inappetence and even death of fish in captivity. An efficient solution to these problems is the injection of pure oxygen directly into the rearing cages. By means of specially designed Keepex oxygenation diffusers, fish can be kept safe during these adverse phenomena.

The use of pure oxygen in fish farming, particularly in salmon farming, has become a successful practice in countries such as Chile, Norway and Canada. Some companies consider the installation of oxygenation systems as standard in all their facilities, regardless of the history of low oxygen at the production sites.
