AZTI has an offshore experimentation area to test different solutions for offshore marine aquaculture. This experimental area is located on the coastal strip between Ondarroa and Lekeitio on beds 50 m deep, within an area declared as of Interest for Marine Aquaculture by the Basque Government:

  • We test systems and technologies for offshore aquaculture in a coastal area that is highly exposed to waves, wind and currents.
  • We monitor the growth of different species of commercial interest.
  • We control the suitability for consumption of the products farmed, as well as their organoleptic quality.
  • We use remote systems to observe the performance of the facility, monitoring the functioning of the systems located in the area, as well as any intrusions, and we monitor environmental and oceanographic parameters of interest for testing (temperature, salinity, currents, wave height and frequency, etc.).


  • We have a site that is fully monitored and controlled, with the required administrative signaling and safety permits and where systems and technologies for offshore aquaculture can be tested.
  • AZTI has the material and human resources to carry out the tests.
