[FR] Les opérations de marquage de thon rouge de l’Atlantique ont été complexes lors de la pandémie. Dans le cadre des projets FishNchip et PROMPT, une importante activité de marquage a repris, ciblant les poissons de la Méditerranée et de l’Atlantique. Ces opérations ciblaient des poissons qui n’avaient pas été précédemment couverts et visaient à étudier de manière détaillée les hypothèses précédentes sur les transitions et migrations dépendant de la taille entre l’Atlantique et la Méditerranée. Ce document présente également d’autres résultats préliminaires visant à diversifier l’approche de marquage pour des déploiements à long terme lancés en 2023.
[ES] Las operaciones de marcado del atún rojo del Atlántico fueron complejas durante la pandemia. En el marco de los proyectos FishNchip y PROMPT se reanudó una importante actividad de marcado de peces del Mediterráneo y del Atlántico. Estas operaciones se centraron en peces previamente descubiertos y tenían por objeto investigar con más detalle las hipótesis previas sobre las migraciones y transiciones dependientes del tamaño entre el Atlántico y el Mediterráneo. También se presentan otros resultados preliminares destinados a diversificar el enfoque de marcado para despliegues a largo plazo, iniciados en 2023.
This work was carried out with funding obtained from France Filière Pêche (PROMPT project) and EMFF (FishNchip). We thank the French and Spanish administrations who helped get the appropriate paperwork completed for the tagging operations. We thank the crew of Onamission, SSFII, SSFIII, 3 frères II and Lucie Manon, as well as Daniel Lopuszanski and all the enthusiastic French and Spanish anglers that made these field operations a success. We also thank Balfegó and their crew, who were key in helping us to carry out the unique operation in Ametlla de Mar next to their facilities.
[EN] Atlantic bluefin tuna tagging operations were complex during the pandemic. Underthe FishNchip and PROMPT projects, substantial tagging activity was resumed, targeting fish from the Mediterranean and the Atlantic. These operations targeted previously uncovered fish and were aimed at investigating in further detail previous hypotheses on size-dependent migrations and transitions between the Atlantic and the Mediterranean. Other preliminary results aiming at diversifying the tagging approach for long-term deployments, initiated in 2023, are also presented herein.
