High quality, sustainable fish fry: free-range fish

Blue Linked is committed to putting high quality, sustainably cultured marine fish fry on the market. We think that current methods of rearing fish larvae into fry in aquaculture are neither natural nor energy efficient. Furthermore, the food animals that are used are unnatural, and the filtering techniques consume high levels of energy. It is time for free-range fish: a sustainable and animal friendly product and an adequate response to the increasing need for animal protein world wide.

Succesful culture of turbot

In our Experimental fish fry hatchery we have the opportunity to raise a range of marine fish species from larvae to fish fry in an ecological and sustainable way. At the heart of the experimental setup is an ecological, sustainable approach, based on an innovative water purification system. The first turbot larvae (Scophthalmus maximus) have been raised succesfully into fish fry.

Innovative water purification system

Unique in our approach is that we keep water both clean and alive in a closed system. We hereby  allow the culture of vulnerable marine organisms such as fish fry. In addition, our technology considerably reduces energy consumption by making traditional water purification techniques, such as sand filters, redundant.

Free-range fish

Our water purification system operates as a self-regulating mini-ecosystem. The technology is copied from nature and therefore safeguards reliable operation. Based on the same three principles by which natural marine ecosystems maintain their equilibrium – living plankton, waste processing and active substrate – clean and living water is produced. All components of the natural food chain – algae, food animals and fish fry – can be kept in a mixed culture. In traditional aquaculture systems, they are cultured separately. We aim to use this innovative approach of water purification in a closed system for the culture of fish fry in a biological way. And we call this new phenomenon: free-range fish.
