Fry Marine was constructed in 2015. The building is developed using the latest building techniques on energy and sustainability. Our facility is self-supported with solar energy. We build every production system according to the RAS principle. This means that water is continuously filtered and re-used.


Next to this our building is organized in such a manner that we can control the hygiene to a maximum. Below you will find the different steps of production in our hatchery.


Photobioreactor algae rhodomonas


In our hatchery we operate 4 photobioreactors. These reactors are lighted by high quality and sustainable LED systems. The spectrum is designed for optimal growth of our algae. We cultivate Tetraselmis suecia for green water technique in our larvae rearing system for turbot and rotifer production. Live algae in larvae production reduces bacterial load in the water. This means we do not have to use any anti-bacterial products in the system.

Live feed

The first 4 weeks our fish larvae eat live feed which mainly consists of zooplankton. We offer our fish larvae two live feeds; rotifers (Brachionus plicatilis) and artemia nauplii (Artemia salina).  By trials we selected the best enrichment for the live feed to ensure the most complete nutrition for our fish larvae.

In our facility we have three broodstocks of turbot (Psetta maxima) and three broodstocks of Dover sole (Solea solea). These fish are held under natural lighting and temperature regimes. We use special broodstock feed to ensure the best for our fish. Hereby spawning is induced in a natural non forced way. This natural approach induces good animal welfare and, directly related, high quality eggs.

We are specially proud of our larvae rearing system. In this system we are able to treat the water to result in a optimum for our fish larvae. So we can control light, temperature and oxygen levels. Further, this systems enables us to introduce pro-biotics to the fish larvae. All combined this results in high quality fish fry.

 A race way is a long stretched basin in which the water is continuously refreshed. The energy requirements for such system is minimal. This principle guarantees sufficient oxygen levels for the fish and waste is directly removed from the system. This reduces stress and improves welfare of the fish.
