Research Applications

AQ1 technology has been used by farmers and researchers to investigate nutrition, genetic performance, feeding regimes, behaviour, palatability, environmental impact and health. The technology controls feed utilization with accuracy and repeatability to eliminate feeding related differences between treatments.

AQ1 technology has been used in trials in replicate tank, pond and cage systems at farms and aquaculture research institutes around the world.
