Fish Farming

On site oxygen production for fish farming

Oxygen is a gas widely used in fish farming to increase productivity. Traditionally, liquid oxygen is supplied to these sites by trucks. This method of supply causes logistic constraints and risks for users.

NOVAIR has designed on-site oxygen production solutions adapted to the specific needs of aquaculture.

When sizing the right system for you, we take into account all relevant parameters that will affect the oxygen diffusion in your ponds, including :
