The OPAGAC/AGAC fleet has always led efforts to improve the sustainability of its fishery. These initiatives, often come from fishermen who are always innovating and trying to improve the fishing capacity of our fleet and reduce the impact on the ecosystem. These projects are completed with the help of scientists from recognized institutions as the Spanish Institute of Oceanography and AZTI, and then are applied to the entire fleet. Our advances have solid scientific and technical bases and the commitment of our research fleet is absolute. These advances are proposed as measures to be applied by other tuna fleets within the RFMOs.
