Restoring Biodiversity In The Ocean

In today’s world, more than 80% of the population live close to the sea, yet less than 1% of global initiatives are currently seaboard-focused. Recent efforts of comprehensive mapping of our oceans reveal the scale of the problem. Exponential increase in population and coastal developmental impacts has had enormous pressure on our valuable sea resources. The worrying trend already shows a sharp decline in fisheries around the world. We need cleaner water, less pollution and start giving more thought to utilities, landscaping, and marine eco-systems. We need integrated solutions and efforts if we are to create the best possible future for our children.

Haejoo Group aims to direct a spotlight on this vital global issue and provide a sustainable solution by implementing marine farms using purpose-built artificial reef complex to conserve aquatic resources and restore marine habitat.



Making an effective man-made reef requires sound planning. Site location is critical in maximising the effect of the reefs whilst ensuring the location is accessible and safe to fish in the prevailing conditions. Reef modules must be designed for the target fish species, each having their suite of preferred shapes, voids, surfaces and profiles. Modules must also be designed for the wave, current and sediment conditions, including cyclonic events.

Modern modules are made of steel or reinforced concrete and are designed to last for at least 40 years. Getting all this right takes experience and expertise.
