In Axis 2, TAPIOCA proposes developing capacity on the use of natural tags, in particular, otolith microchemistry and stable isotope analysis that provide great advances in the comprehension of the ecosystem functioning (Axis 2.1.). The second specific objective (Axis 2.2.) is to foster expertise and exchanges on biologger’s use/development and data handling using advanced statistical modelling.


Axis 2.1. Natural tags

Problematic and gaps:

Natural tags: conservative or semi-conservative biomarkers (e.g. otolith microchemistry and stable isotopes) to reconstruct organisms’ past-history.


Scientific and technical capacity building:

Use of natural tags to:

  1. assess fish movements and connectivity patterns;
  2. identify essential habitats (e.g. nursery);
  • describe marine food web structure;
  1. assess resource partitioning processes among fish;
  2. Identify heavy metals contamination sources and impacts


Axis 2.2. Artificial tags (biologging)

Problematic and gaps:

Artificial tags (e.g. GPS, cameras) allows continuous measurement of predators and fishers behaviour, animal state and environment.

Call for a quantitative support to take better profit of these data.


Scientific and technical capacity building:

Objective: developing expertise and exchanges on:

  1. logger’s use, casing, and deployment;
  2. data handling and advanced statistical modelling.
