Sustainable seafood can come from both wild fish stock and commercial aquaculture. Considerations for whether a fish is considered sustainable include:
- Stock levels of this variety in the ocean.
- The impact of catching this variety on other marine species and the sea floor.
- The way in which this variety has been caught, including avoiding any bycatch.
- Sustainable wild varieties are usually from fast growing, highly productive species.
- Sustainable-farmed species are usually grown in small, closed farming systems that are sensitive to their coastal environment and or depend on wild stock for feed.
What can we do about it?
It's easy to choose sustainable seafood with the guides or app on the Australian Marine Conservation Society website. With either of these tools, you can check if the varieties you are considering buying are sustainable.
Sustainable canned tuna
Tuna is one of the most common fish consumed. With such a large selection of brands on the shelves, it can be a little tricky to figure out which is the most environmentally conscious option. To help you can:
- Choose tuna that has been caught using 'pole and line' or 'FAD-Free'.
- Avoid at-risk species, such as yellowfin tuna, by choosing skipjack or albacore.
- Choose tuna caught in Australia.
As creatures of habit, we tend to find a brand we like and stick to it without paying much attention to the labels. Check your favourite brand against the canned tuna guide on the Greenpeace website and avoid having to worry about the labels again.
