Oysters make the world a better place

It’s true, they do! Oyster farming isn’t just good for our taste buds, it’s good for the environment and your health. It’s the trifecta of farming and feasting: a win-win all around.

There’s more to oyster farming than just great food

These amazing bivalves are environmental champions. Oysters are the clean-up crew of the sea. They also provide habitat for fish and other sea creatures and are packed with nutrients and omega-3 fatty acids.

Environmentally friendly farming

Aquaculture is recognised as a key solution to the demands of our growing population. Unlike most forms of agriculture, oysters do not need us to grow or catch food to sustain them. This reduces land use, transportation emissions, use of chemicals and fertilisers and the burden on other ecosystems. Unlike ruminant animals like cows and sheep, oysters don’t produce methane. Check out the infographic from Oceanfarmr.

And oyster farming is far from being a wild free-for-all. Oyster farmers act as guardians, making sure water quality is high and everything is sustainable. They keep a close eye on growth and follow the best practices to make sure we will all have tasty oysters for the future.

They filter out the bad stuff

Each lovely little oyster filters around 20 litres of water daily, enough for five humans. Putting it another way, according to the NSW Department of Primary Industries, “On average, a farmed Sydney Rock Oyster will filter an estimated 250,000 litres of estuarine river water in its lifetime, removing large quantities of suspended material, chiefly nutrients bound in phytoplankton”.

Oysters gobble up excess nitrogen, phosphorus, nutrients, sediment, and other pollutants from waterways, allowing sunlight to benefit entire ecosystems. They purify our waters and revitalise our precious ecosystems. Oysters we harvest carry this surplus nitrogen with them, removing it from the environment. The shells contain calcium carbonate, which can help remove carbon dioxide from the water.

So, in a nutshell (or an oyster shell), oyster farming isn’t just about good food.

Oyster farms bring environmental benefits to coastal seas, harbours and estuaries. The presence of oysters and other shellfish creates a firm bottom substrate, which is ideal for mussels, barnacles, anemones, and other creatures to grow in. Oyster beds are also used by a variety of fish to lay eggs and protect themselves from predators.

Oysters help boost the local fish population, keep the water clean, satisfy our taste buds, and are low in saturated fat and are excellent sources of omega-3 fatty acids, iron, zinc, and vitamin B12.

Popping oysters into your diet can be a tasty way to support environmental conservation and promote sustainable food choices. As the people at Oceanfarmr point out in their infographic, aquaculture supports the United Nation’s Sustainable Development Goals of eliminating poverty, hunger, water scarcity, biodiversity loss, and environmental degradation.
