Mainstream Aquaculture Group

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. Over two decades of innovation, MainStream Aquaculture has developed proprietary technology that has enabled its growth. MainStream has become one of the largest Barramundi producers and suppliers in the world and has developed a vision to become the world’s leading supplier of premium white fish. MainStream Aquaculture operates the world’s largest aquaculture system of its type in Melbourne, Australia, as well as multiple award-winning pond farms in Far North Queensland. MainStream’s production facilities are supported by an advanced selective breeding program conducted in the world’s largest Barramundi hatchery in Melbourne, Australia, along with its research centres in Townsville, Australia. This program underpins MainStream’s farm operations through the supply of high quality juvenile Barramundi that demonstrate rapid growth, low growth variance, high fillet yield and disease resistance. MainStream’s vertically integrated business supplies premium table fish into the Australian and USA markets and exports seed stock from its breeding program into 25 countries across 5 continents.
