GIS Innovative Solutions

Fish Health

The GIS system delivers super saturated levels of dissolved oxygen while maintaining total gas pressure allowing for increased exposure times. The result of this is higher efficacy of treatment, healthier fish and reduced number of treatments.


The GIS innovative transportation system provides sustained dissolved oxygen levels while stripping CO2 thereby improving water chemistry. Our system will allow for more efficient fish transfers.


The GIS innovative solution delivers more effective maintenance of dissolved oxygen thus improving fish health, stocking density and provides fish with 100%+ DO saturated water independent of water temperature.
