The average size fish farms are in the midst of an explosive scale increase having not long ago considered 1,5 00 tons per year (TPY) very large. Now it is quite common to see plans of 10,000 tpy  fish  production and more per farm. When farms were small (~<300 tpy) , so was the volume of oxygen required to support fish growth. There was one dominant source of oxygen supply - liquid oxygen (LOX) - and an occasional oxygen PSA onsite generator.

With much larger  fish  farm sizes, the volume of oxygen demand has proportionately grown as well. No longer is  trucked-in  LOX alone the go-to source to achieve the best economics and reliability. Now there are a plethora of oxygen source technologies and suppliers to choose from  - LOX, PSA, VPSA, and cryogenic generators. No one source is a panacea for all farms. However, each source has its place in achieving the best cost and reliable oxygen supply. And each has its own technical and commercial advantages that also impact the design of the fish farm itself. When designing the farm, it is imperative to understand the oxygen source so that they are compatible with each other plus deliver the ideal economic farm business case.

This presentation intends to provide the fish farm owners and designers the technical, reliability, commercial and economic differences among each technology and how to navigate the custom selection process to determine the best fit for the specific farm application ,  thus ensuring sustainable aquaculture operation.
