  • Floating RAS design continued, interest from other farmers, cooperation with Fraunhofer IGD to develop precision farming processes within our system

Q4 2022

  1. Co-organized a world-class workshop on tuna reproduction. Jan and Paul from our team met with our partners from the IEO plus external tuna and fish reproduction experts from Israel, the Netherlands, Greece and Japan;
  2. Met with potential customers in Spain and Malta. Strong interest in the market for our product, juvenile Atlantic Bluefin Tuna.
  3. Entered into Letters of Interest with existing tuna grow-out facilities, producers of seabass and seabream, and with retail chains and seafood distributors.
  4. Cooperation agreement established with Skretting for the joint development of optimized tuna dry feed. This is a very important step towards a truly sustainable tuna aquaculture. Please see press release:

Q3 2022

Q2 2022

  • Site selection process finalized: We decided for the Port of Castellon in Spain
  • Start of permitting process
  • Our scientific tests at the IEO facility have been progressing well
