How we farm fish sustainably
A Recirculating Aquaculture System (RAS)
Recirculating Aquaculture Systems (RAS), when compared to traditional open pond or ocean based aquaculture operations, are the preferred method of sustainable seafood production for the future.
RAS uses technology and advanced production methods to enable the growth of aquatic species in controlled, land based culture environments.
Culture species are grown in an optimum environment designed to minimise the stress on the culture species, reduce environmental variations associated with seasonal change, and protect from disease, parasites and predators. These all impact greatly on traditional open aquaculture systems.
Recirculating Aquaculture Systems (RAS) are highly sustainable
Compared to traditional aquaculture methods, aquaculture using RAS technology, coupled with the year-round controlled environment and small land foot print required for production, means RAS production can be located close to markets and the end user. These factors significantly reduce carbon kilometres associated with transporting food long distances, and brings a premium fresh product to the local market.
More efficient
- Capable of higher stocking density
- Achieve higher feed conversion ratios
- Maximises growth rates
- Lower fingerling mortality rates
- Temperature controlled environment regulates energy use
- No downtime between harvests (eg. fallow periods)
Bio-secure food production
- Production environment ensures regular production of premium quality seafood product providing a secure food source
- Not subject to variability in ocean water conditions
Environmentally friendly
- More efficient use of water through the use of recirculation techniques
- Restores the quality of water
- Lower environmental impact of nutrient outputs
- Sustainable land based seafood production reduces impact on ocean seafood stocks
What species are we farming?
A broad range of both freshwater and marine/saltwater seafood species can be farmed in RAS.
This includes barramundi, grouper, coral trout, Murray cod, kingfish (cobia), prawns and others.
