The ecosystem-based approach promoted by the EU Marine Strategy Framework Directive and the Common Fisheries Policy highlights the importance of management based on scientific data and a comprehensive understanding of the marine environment.
To move towards sustainable exploitation, it was necessary to intensify sample and data collection during assessment surveys—particularly for key species such as Bay of Biscay anchovy—and to develop tools capable of simulating different fisheries management scenarios.
AZTI designed and evaluated harvest control rules adapted to anchovy dynamics, using mathematical models and simulation tools to analyse their performance.
At the same time, the methodology used in the JUVENA survey was consolidated to estimate a juvenile abundance index and to anticipate recruitment levels for the following year.
In addition, the stock assessment model was improved by integrating the best available biological and fisheries information, enabling accurate application of the harvest control rules.
Results were discussed with managers, scientists, and representatives of the fishing sector, whose contributions were incorporated into the final design of the plan.
Implementation of the Bay of Biscay anchovy management plan, in force since 2010 with successful outcomes.
Unanimous adoption and support by all stakeholders, making it a benchmark model for sustainable fisheries management.
Consolidation of scientific methodologies to estimate recruitment and juvenile abundance.
Development of models and simulation tools that strengthen the evaluation of management strategies.
Scientific publications led by AZTI, demonstrating the quality and relevance of the work.
