As diners become more environmentally conscious, their food preferences—especially for seafood—are under closer scrutiny. Navigating sustainable seafood options can be complex, but making the right choices has a positive impact on the planet.

In Australia and New Zealand, some seafood varieties are generally recognised as more sustainable—especially when sourced from responsibly managed fisheries or certified farms.

🟩 New Zealand Hoki
Managed under a robust fisheries system and regularly assessed, Hoki with Marine Stewardship Council (MSC) certification ensures responsible sourcing.

🟩 Australian Wild-Caught King Prawns
Sustainably fished king prawns—especially those caught using bycatch reduction devices (BRDs)—can be an environmentally sound choice.

🟩 New Zealand Greenshell Mussels
Farmed using longlines or ropes, these mussels not only have a low impact on the environment but also improve water quality by filtering nutrients.

🟩 Australian Blue Grenadier (Hoki)
Known locally as Blue Grenadier, this deep-sea fish becomes a sustainable choice when caught using midwater trawls in well-managed fisheries.

🟩 Australian Farmed Atlantic Salmon
When sourced from farms using responsible aquaculture practices, such as sustainable feed and closed containment systems, farmed Atlantic salmon is a sound option.

🟩 Australian Sardines
Fast-growing and abundant, sardines are low in contaminants and considered highly sustainable.

🟩 Australian Farmed Barramundi
Responsibly farmed barramundi, especially from land-based systems or recirculating aquaculture systems (RAS), offer a low-impact option with strong environmental safeguards.

🟩 Australian Flathead
Species like Dusky or Sand Flathead, when caught using handlines or traps, are considered more sustainable due to the reduced impact on marine ecosystems.

🟩 Australian Blue Swimmer Crab
Caught using low-impact traps or pots, Blue Swimmer Crabs from well-managed populations are another good choice.

Sustainability can vary depending on location and the methods used by producers. To ensure ethical and environmentally responsible seafood, look for certifications such as:
