Our Business

Mainstream was founded in 2001 with a vision to build a “business for the future” by becoming the world’s leading provider of recirculating aquaculture seafood products.  Through over a decade of successful research and development, Mainstream Aquaculture has developed proprietary technology that is unique in enabling continuous (year round) high quality production of the popular table fish, Barramundi.  Mainstream Aquaculture operates the largest recirculating aquaculture system in mainland Australia, as well as an award-winning pond system in Far North Queensland, making them a top 5 domestic provider of Barramundi.

Mainstream’s facilities are supported by an advanced selective breeding program conducted in the world’s largest Barramundi hatchery in Melbourne, Australia, along with our research centre in Townsville, Australia.  This program underpins Mainstream’s production process through the supply of high quality juvenile Barramundi that demonstrate rapid growth, low growth variance, high fillet yield and disease resistance.

Mainstream distributes its food products into premium retail outlets and restaurants around Australia and exports juvenile Barramundi to 24 countries across 5 continents.
