Considering the priorities stated initially by SCRS, the Steering Committee set as the main objective of the GBYP the improvement of our knowledge and understanding of the Atlantic bluefin tuna (Thunnus thynnus) stocks and populations. Aiming at the achievement of this general objective, the following specific objectives were set:

a) Improve basic data collection through data mining developing methods to elaborate these data and to estimate sizes of fish caged, development of fisheries-independent information surveys and implementing a large scale scientific tagging programme.

b) Improve understanding of key biological and ecological processes through electronic tagging experiments to determine habitat and migration routes, broad scale biological sampling of live fish and dead fish landed (e.g. gonads, liver, otoliths, spines, etc.), histological analyses to determine bluefin tuna reproductive state, biological and genetics analyses to investigate mixing and population structure; and ecological processes, including predator-prey relationships;

c) Improve assessment models and provision of scientific advice on stock status through improved modelling of key biological processes (including growth and stock-recruitment), further developing stock assessment models including mixing among areas, and developing and use of biologically realistic operating models for more rigorous management option testing.

The GBYP Steering Committee has the role to guide and refine the Programme. It is regularly informed and consulted by the Coordinator for all relevant issues and for the Calls for Tenders to be issued. The Steering Committee meets not less than once a year, to verify the activities done, refine the Programme, propose follow-up of the Programme and adopt the budget.

Coordination team

The GBYP coordination team is nowadays composed by the Program Coordinator, an Assistant Coordinator and a Database Specialist. Such team carry out the day to day tasks related to the implementation of the project, including the elaboration of the Calls for different types of contracts, the reports on the different GBYP meetings and the Annual and Executive Reports. The open calls can be downloaded from ICCAT home page (Latest news).

Along the different phases of the Programme, the Steering Committee has set the following activities:

  • Data mining, data recovery and data elaboration.
  • Aerial surveys.
  • Biological and genetic sampling and analyses.
  • Conventional and electronic tagging.
  • Modelling approaches.

Annual Budget

The GBYP is funded by CPCs and other entities, as Chinese Taipei and ICCAT Secretariat. Among CPCs, EU provides 80% of total budget. The evolution of the total budget along the Programme, by type of activity, has been as follows:

Data and Publication policy

The publication policy concerning the results obtained by the various researches carried out within this programme must follow the rules included in the contract between the ICCAT and the funders and those rules are mandatory for all the participants to the GBYP. The acceptance of a contract provided by the GBYP will automatically imply the acceptance of the “Publication policy and Editorial rules” here detailed.

  • 1 Ownership of the results of the Programme (GBYP), including industrial and intellectual property rights, and of the reports and other documents relating to it shall be vested by ICCAT.
  • 2 The result of each action carried out within the Programme (GBYP) and all the scientific results obtained by these actions shall be presented to the ICCAT-SCRS at the first opportunity.
  • 3 The scientific results of actions carried out within the Programme (GBYP), after the presentation to the ICCAT/SCRS, can be published, entirely or partly, on the ICCAT Collective Volume of Scientific Papers as well as in other scientific journals. The Authors who wish to publish these results in other scientific journals shall previously require a permit to ICCAT. ICCAT, following the spirit of this scientific programme, encourages the Authors engaged in research action within the Programme (GBYP) to disseminate their results, particularly in peer-reviewed international scientific journals.
  • 4Each report or article concerning the results obtained within the actions of the Programme (GBYP) must include the following sentence: “This work has been carried out under the ICCAT Atlantic-Wide Research Programme for Bluefin Tuna (GBYP), which is funded by the European Union, several ICCAT CPCs, the ICCAT Secretariat, and other entities (see https://www.iccat.int/gbyp/en/overview.asp). The content of this paper does not necessarily reflect ICCAT’s point of view or that of any of the other sponsors, who carry no responsibility.
