TL;DR: G gonadal development in BFT correlates well with higher sea surface temperatures, which reflects a situation in which the eastern Mediterranean basin may function as a habitat for young BFT, until they gain a larger MB and are able to move to the Atlantic Ocean.

Further evidence of spawning of bluefin tuna (Thunnus thynnus L., 1758) and the tuna species (Auxis rochei Ris., 1810, Euthynnus alletteratus Raf., 1810) in the eastern Mediterranean Sea: preliminary results of TUNALEV larval survey in 2004
TL;DR: The concentration of bluefin tuna larvae was highest in the Bay of Mersin, and the collected larvae in this area were composed mainly of 5–9 mm size specimens.

TL;DR: In this article, the authors investigated the migratory movements of Atlantic bluefin tuna (Thunnus thynnus, L.) between the Western and Eastern Atlantic, the two-stock hypothesis remains untested and exchange rates are still unidentified.

TL;DR: A molecular approach employing mitochondrial and nuclear genes to identify larvae collected from three spawning areas in the Mediterranean Sea by different institutions working with a regional fisheries management organization reveals important differences in the accuracy of the taxonomic identifications carried out by different ichthyoplanktologists following morphology-based methods.
