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.

Advantages

  • 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.


Implementation

  • 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.

Experience

  • 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.
