WG-FSA-2022 - 4.2 - Toothfish (Dissostichus spp.)

Resumen

We analyzed data provided by Secretariat on fish tagged and subsequent recaptures in Subareas 88.1 and 88.2 during the period 2009-2017.

In our opinion, it will be possible to improve the tagging data in the toothfish fishery by moving the dimensions of the vector spaces (sea currents and migrations) closer to each other.

We provided some proposals that could be to consider in tagging framework .
