What inspired you to become involved in the seafood industry?

Dr. Paul Harrison was inspired to feed the world with delicious, sustainably produced fish through best-practice aquaculture technology. Holding a PhD in aquatic biology and having experience working across Australia and abroad, Paul and his mate decided to set up Mainstream Aquaculture in Wyndham, Victoria, Australia in 2001.

Please tell us a little about MainStream Aquaculture.

MainStream has five aquaculture sites in Australia – two in Wyndham Victoria and three in Far North Queensland. The company has also established a farm in Arizona to satisfy the growing demand for the species in the US. The Wyndham farms use state-of-the-art, low-footprint, low-water-use technology. “We located it here because it is so close to the vibrant Melbourne market,” Harrison says. “And because we can source pristine geothermal water from about 300 meters below the ground. This sustainable water source supports our farms from which we can harvest and supply to market in a matter of hours.” The Far North Queensland farms, located in Innisfail and Port Douglas, use salt water from the Coral Sea to grow the fish. These farms feature beautiful wetlands that clean the water used in farming and support an abundance of natural wildlife.

MainStream Aquaculture sells its products under the brand Infinity Blue Barramundi.

“Sustainability is one of our core principles; it drives decisions we make in growing the business and ensures that we can supply a great tasting, healthy fish while supporting the planet,” Dr. Harrison says. “Showcasing that we hold sustainability credentials is important to us as a company and producer as well as to the general market.”

Why do you love working in aquaculture?

Dr. Harrison and all the people working at MainStream Aquaculture believe in the positive impacts that aquaculture can have on oceans and wild fish stocks. MainStream Aquaculture’s mission is to feed the world with high-quality fish and supply it in an environmentally sustainable way.

The efficiencies and benefits of aquaculture on the natural environment have been evident in the past 20 years. In particular, the main advantage is that it takes a lot of pressure off wild fisheries. Aquaculture allows us to provide fish as food without stripping the oceans bare.

Dr. Harrison adds that “there is a lot we need to do to make the ocean better. Population growth has gone far enough along that we may never get back to what it was when there were fewer people around. But the ocean can still be a great and healthy environment”. “Our motto is that by eating Infinity Blue Barramundi, you are saving the oceans, one fish at a time!”
