    Customer Challenge


    The Kingfish Zeeland fishery has a clear mission: become a leader in the sustainable production of premium marine seafood. Their proprietary recirculating aquaculture systems (RAS) use seawater and organic feed to deliver a healthy, antibiotic-free delicacy: the Dutch Yellowtail or Kingfish. It is the only land-grown Yellowtail, certified by the Aquaculture Stewardship Council & Best Aquaculture Practices.“During the on-growing stage, the fish need enough light to see theother fish and their food, and a long day to optimize their growth and feed conversion ratio,” says Kees Kloet, COO Kingfish Zeeland. “And the lighting system needs to withstand our harsh saltwater environment.”

    The LED lighting solution


    The Kingfish Company set-up has three LED lights above each tank and a proven light recipe for growing fish to promote steady growth via a controlled system. The fish can see each other and their food, dusk and dawn are simulated very well and the fish experience an endless summer via the software driven control system. The slow ramp up and deep dimming capabilities reduce stress and promotes optimal growth for this highly active fish.


    The team spent many years working with Wageningen University in the Netherlands, just to select the right fish species. Their eco-friendly facility uses no antibiotics or vaccines, green energy, heat exchangers and a sophisticated water treatment and recycling technology. With this concept, the company achieved 30%-40% higher production and the confidence to scale up their production.
