At the coffee table in the breeding centre of our knowledge partner Blue Linked (Hazerswoude-dorp), Michaël Laterveer (left) tells us what happened recently. To his right, Marja Doedens of Stichting De Blauwe Polder on Texel is seated. The aim of this foundation is to set up a breeding ground, platform and test location for innovations in fish farming and other seafood. The Wadden Sea island of Texel is the flywheel for this. From there, the innovations should spread to other locations. On the right in the picture: Renate and Frans van de Veer, secretary and treasurer of the Oceans at Work Foundation.
In the hatchery, Michaël Laterveer explains circular fish farming using a demonstration model of the innovative breeding system (left). Without the use of traditional filter installations and energy-consuming pumps, the seawater is cleaned in a natural way. The waste products of the fish are decomposed and available for the rest of the food chain. Exactly as it works in nature.
The ecological approach requires the cultivation of all links in the food chain: microscopic algae, but also planktonic animals. Glass cylinders (centre) are already in place to house the plankton. Experiments show that they grow perfectly under these conditions.
Preview of the near future
And then, of course, we looked at the space where it all will happen (right). It is still hard to imagine that the bare climate room will soon house the growing systems. The white chalk marks on the floor show where the 10-metre containers are to be located. First we have to prepare the floor, lay a drainage channel and request tenders from the company that will be supplying the material. Every day we take a new step.
