Hatchery

 

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

Algae

In our hatchery we operate 4 photobioreactors. These reactors are lighted by high quality and sustainable LED systems. The spectrum emitted by the LED lights is designed for optimal growth of our algae. We cultivate Rhodomonas balitca. This algae is one of the highest nutritional algae in the world and very suitable for live feed production.

Copepods

The algae are distributed to our Acartia tonsa copepods. Each tank holds up to 5 million copepods. The adult copepods produces eggs, which we collect, rinse disinfect and store for a short period. The eggs are hatched and feed to the young turbot larvae. This is an excellent (natural) starter feed with high nutritional value.

Live feed

The first 4 weeks our fish larvae eat live feed which mainly consists of zooplankton. We offer our fish larvae three live feeds; copepod nauplii (Acartia tonsa), rotifers (Brachionus plicatilis) and artemia nauplii (Artemia salina). This combination of feed ensures optimal nutrition for the young fish.

Broodstock

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.

Larvae

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.

Raceways

 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.
