At Murray Cod Australia, we apply science-based innovation and sustainable farming practices to food production. It helps us make a positive impact on people’s plates — and the planet!
Our goal is to be at the forefront of sustainable farming globally for the aquaculture industry.
Here are the areas where we’re continually improving:
Feeding our fish
We’re working towards improving the sustainability of our feeds by reducing marine products and assessing novel ingredients, all while optimising fish growth and health. Our ultimate goal is to grow fish using the least amount of feed to produce the max amount of protein. We don’t use antibiotics in our grow-out systems and no hormones are used at any stage during Murray cod production.
In 2025, our key supplier recorded record low forage fish dependency ratios (FFDR), reflecting industry-wide progress towards circular feed solutions using byproducts from sustainable fisheries.
Managing our organic waste
There are a number of ways Aquna manages organic waste. Water usage and quality is monitored closely. Research and development of by-products is a priority that aligns with our whole-fish philosophy to minimise waste. We work with local companies to ensure no organic waste from our processing facility is sent to landfill.
Efficient water usage
The way we have designed water infrastructure on our farms is one of our most celebrated sustainability achievements. We use water to fill our ponds and occasionally to top up or exchange freshwater to maintain a quality growing environment for our fish. Our farms are designed so we can reuse the nutrient-rich water from this exchange on crops and pastures.
Traceability
Our fish is traceable from grow-out through to processing and distribution, allowing us to improve and verify our sustainability practices.
Whole fish philosophy
Aligned with our whole fish philosophy, we are focusing on waste minimisation research and development initiatives with biotechnology companies to help us maximise the yield from one single fish. In 2023, we launched our world first Aquna Gold Murray Cod caviar.
Conservation through Restocking programs
At Aquna, we borrow brood fish from the wild to breed fish for government restocking programs, local councils and recreational fishing groups. Since commencement of this initiative, we have bred and released millions of fingerlings with zero impact on wild populations.
Animal welfare
Our free-range pond system, where fish swim freely outside of cages, has improved fish health, growth rates, and operational efficiencies. These low-touch, recirculating aquaculture systems use natural wetlands to maintain water quality. Encouraging trial results have led to expansion at other Murray Cod Australia sites.
CERTIFICATIONS
Murray Cod Australia has been granted Halal certification by the Australian Halal Authority and Advisers.
This certification is a key milestone, unlocking access to the growing Halal consumer market — not only in Australia, but in the Middle East and across Southeast Asia. It reinforces our commitment to quality and to expanding the reach of our premium fish worldwide.
The Good Fish Guide, an app and website, is a sustainability initiative by the Australian Marine Conservation Society. The guide is an independent reference that lists species of Australian seafood and gives them a red, amber or green light, depending on sustainability. It helps chefs and consumers make informed decisions on the seafood they eat and serve.
Farmed Murray cod is listed as green in the guide.
