AZTI provides fishermen with oceanographic advanced information to determine high-probability fishing areas, based on technology developed in-house (OCEANTIC), for the coastal and offshore fleet, and for the fleet of frozen tuna vessels.

  • Search for favourable oceanographic conditions for the presence of pelagic fishery species.
  • Training courses in the use of the IT software which relates oceanographic maps and target fishery resources.
  • Weekly technical support in oceanography.
  • Service Assessment
  • Weekly maps with high-probability fishing areas during the service contract period.
  • Weekly monitoring via e-mail and regular visits to the base ports.
  • Statistical studies relating catches to oceanographic conditions.


  • Understand and predict the distribution of schools of the target species.
  • Reduced fuel consumption and days at sea.
  • Increased safety at sea, avoiding adverse ocean-meteorological areas.

Applicable sectors

Fishing companies (vessels and offices): freezer tuna seiners, longliners, coastal tuna vessels, pelagic trawlers (horse-mackerel, mackerel, sardine, anchovy, etc.).

Understanding and predicting the distribution of schools of the target species allows fuel consumption and days at sea to be reduced


  • Installation and handling of software and basic training in the relationship between oceanographic maps and target fishery resources (1 day).
  • Joint determination of the fishing area and season and the target species with the skipper/captain (1 day).
  • Statistical analysis of the data provided in order to understand the behaviour of the target species and its temporary space distribution in relation to oceanographic conditions (3 months).


  • 20 years’ experience offering oceanographic interpretation for fishing purposes (oceanographic map management software, statistical analysis of the relationship between catches and oceanographic conditions for different oceans).
  • Multi-disciplinary work team: biologists, oceanographers, etc.
  • Knowledge of the coastal and offshore fisheries sector.

Proven track record

Over a 15 years of map analysis and technical guidance to over 350 vessels in the Pacific, Indian and Atlantic Oceans.
