Integrated fisheries resource assessment from a biological perspective

Predicting recruitment success to support fisheries management

We develop models that allow different biological-based management strategies to be assessed (population status).

  • Age determination.
  • Determination of reproductive parameters.
  • Study of annual and daily growth rates through macroscopic and microscopic otolith analysis.
  • Determination of mortality rates.
  • Transport and migration through tagging techniques and/or otolith micro-chemical analysis.
  • Trophic relationships using taxonomic and genetic techniques.
  • Comprehensive study of fishery population recruitment and dynamics and their regulatory factors.

We develop models that allow population status assessment using different biological management strategies.

Applicable sectors

  • Public Administrations.
  • Management Bodies.
  • Fishermen’s Associations.
  • Universities and/or technology centres specialised in the fisheries sector.


  • Comprehensive understanding of the biology of fishery populations.
  • Determination of the processes regulating their recruitment and population dynamics.
  • Feed and support for fisheries management models.
  • Feed of multi-specific and ecosystem-based management models.
  • Integration in the know-how of ecosystems and processes regulating their dynamics.

Thanks to the research carried out, closed fisheries have been opened, anticipating recruitment success, with the corresponding economic benefits for the sector.


  • Jointly with the client depending on the prior knowledge and the objectives pursued: Basic research, fishery species management, ecosystem management, etc.
  • We do not only seek to apply it to fisheries management but also to provide visibility to the scientific community through scientific publications.


  • 25 years’ experience in the comprehensive assessment of fish species and the factors controlling their dynamics.
  • Multidisciplinary team with experts in fish species assessment and management.
  • High level of expertise in different techniques: growth and mortality (otoliths), fecundity (histology), movement (biophysical models, tagging, otolith microchemistry), trophic relationships (stomach contents, genetics).
  • We have numerous European contacts in the fisheries biology sector, complementing our fields of activity.

Proven track record

  • Sustainable population management and sustainability of extractive fishing activities.
  • Opening of closed fisheries, anticipating recruitment success, with the corresponding economic benefits for the sector.
  • Over 100 scientific publications in ISI-indexed journals related to biology and fisheries management.
  • External guidance in third-country scientific projects.
  • Cooperation with foreign Public Administrations in the implementation of integrated assessment and fisheries management methods.
