Stock structure of tropical tuna in the Indian Ocean: an otolith microchemistry approach

Abstract

Entre las especies que desempeñan un papel importante en la economía azul, se encuentran las denominadas como túnidos tropicales; el listado, Katsuwonus pelamis, el rabil Thunnus albacares y el patudo Thunnus obesus. Estas especies son altamente migratorias y habitan las aguas tropicales y subtropicales de los tres océanos principales (Atlántico, Índico y Pacífico). Dentro de su área de distribución geográfica, el océano Índico es un caladero de vital importancia para las capturas de estas tres especies, sin embargo, es del que menos información se posee. Aunque en la actualidad cada una de las especies de túnidos tropicales se gestiona como un sólo stock en el Océano Índico, siguen existiendo dudas sobre la conectividad y dinámica espacial de las mismas. En este contexto, el objetivo principal de esta tesis es investigar la estructura de los stocks de túnidos tropicales en el Océano Índico, mediante el análisis microquímico de los otolitos (pares de piedras que se encuentran en el oído interno de los peces).
