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.

Supplementing Technologies in Ocean Farming

In addition to the Blue Revolution some land based advanced farming methods can also be adopted on water surfaces like floating hydroponics, aquaponics, and aeroponics. These innovative systems will adapt to marine environments, offering new ways to grow food on water.

Hydroponics on Water

Hydroponics is leading the charge by enabling plants to grow without soil, directly in nutrient-rich water. This method uses floating platforms equipped with LED lights to support plant growth, offering a solution for producing food where land is limited.

Aquaponics: A Dual Approach

Aquaponics combines fish farming with hydroponics in a circular system where fish waste serves as a natural nutrient source for plants. In turn, the plants help clean the water for the fish. This method exemplifies efficiency by using space and resources wisely, reflecting the goals of the Blue Revolution.

Aeroponics: Misting for Growth

Aeroponics represents the forefront of technology, where plants receive nutrients through a fine mist, eliminating the need for soil or continuous water immersion. When applied to floating farms, this method ensures maximum water and nutrient use efficiency, showcasing advanced agricultural practices.

The Role of Vertical Farming

Vertical farming is also making strides by stacking crops vertically to save space and allow for year-round production. This approach reduces the need for pesticides, conserves water, and offers precise control over growing conditions, thanks to modern technology like climate control systems and LED lighting.
