Sustainability is at the core of every choice we make.

At the Kingfish Company we focus on high quality production

with the lowest environmental impact. This environmental

focus is realised by using only 100% green energy and

installed custom made heat exchangers.

But also in our responsible use of natural Oosterschelde water in the basins where we further purify the water on arrival and filter it again before it is returned back to the sea. Our commitment to animal welfare goes hand in hand with our sustainability commitment, and we are proud to provide the best possible living conditions for our fish resulting in a high quality and healthy product for our consumers.

To grow a high quality product, our fish must thrive in the most optimal conditions.

It starts with fresh North Sea water flowing through a pristine nature reserve marine estuary. Then we make it even better: our advanced system purifies, enriches and adapts the water to the Yellowtail's optimal conditions.

Working closely with some of the world's leading

equipment suppliers and engineering companies, we have access to proprietary first hand expertise regarding the requirements and demands of the Yellowtail in land-based recirculation systems. This has resulted in Kingfish Zeeland’s production facility, which has been designed to achieve levels of control, safety, reliability and sustainability not currently available in alternative production systems.

Fresh marine water is drawn at high replacement rates, purified, oxygenated and meticulously monitored and controlled to create optimal temperature, light and water conditions for the Yellowtail, resulting in healthy, strong and apparently happy fish.

Substantial efforts and costs have been incurred in order to assure that our operation is safe and healthy for our customers, stress-free and humane to our fish, and careful to protect the nature that surround us. Our sustainability measures include:

• No Antibiotics, No Vaccines: keeping our water pristine has its benefits happy healthy fish in optimal conditions can do without antibiotics or vaccines.

• Aquaponics: Our outflow water is rich in nutriants before it is biologically purified in our internal water treatment systems, in order to keep discharge as low as possible. With that in mind, we intend to maximize the use of our outflow as fertilizer for Salicornia crops and Algae production.

• Fresh Water Conservation: Operating on sea water, we do not waste a precious and rare resource.

• Bio Security: waste water treatment with incorporated solids removal, ensures a safe discharge of our outflow water. As an additional safety measure, the discharge of our hatchery and quarantaine units is sterilized by powerful UV and Ozone treatment, ensuring no biological impact from the farm to its natural surroundings.
