Fish Herding: The Future of Open Ocean Mariculture
The Velella Mariculture Research Project represents a monumental leap in the realm of sustainable aquaculture, thanks to its pioneering use of unanchored drifter pens, or ‘Aquapods,’ in the open waters off Hawaii’s Big Island. This innovative approach doesn’t seem to have a name, so let’s call it “Fish Herding,” embodies the next frontier in ocean farming, merging cutting-edge technology with a farming method that leaves virtually no environmental footprint.
Aquapods harnesses the natural currents and eddies, allowing the drifter pens to roam freely in the nutrient-rich open waters. This method not only minimizes the ecological impact but also mimics the natural habitat of the fish, promoting healthier and more robust growth. The drifter pens are designed to be in harmony with the ocean, ensuring that there is no adverse interaction with the delicate coral reefs or the ocean floor.
The potential of Fish Herding with Aquapods to revolutionize sustainable aquaculture is immense. By moving further offshore into the open ocean, where water circulation and ecosystem resilience are stronger, this method offers a scalable and environmentally friendly solution to meet the world’s growing seafood demands.
