Stable Isotope Analyses of Yellowfin and Blackfin Tuna Eye Lenses Reveal Life History Patterns
Fisheries Oceanography, EarlyView.ABSTRACT Spatial geography, ontogenetic movement, and trophic patterns of mobile species are key elements of species life history, and knowledge of them is critical for effective marine resource management. For yellowfin tuna (Thunnus albacares; YFT) and blackfin tuna (Thunnus atlanticus; BLFT), residency durations and ontogenetic movements in the Gulf

Fisheries Oceanography, EarlyView.ABSTRACT Oceanographic variability plays a critical role in shaping the migratory behavior of the Atlantic bluefin tuna (Thunnus thynnus). This study investigates the thermal preferences of individuals migrating through the Strait of Gibraltar and the Gulf of Cádiz during pre‐ and post‐spawning movements.

Reproduction of Atlantic bluefin tuna
Fish and Fisheries, 2020 AbstractThe reproductive success of fish populations depends on their reproductive potential and offspring survival to maturity. The reproductive potential affects recruitment and hence populations’ resilience and productivity. Extensive research carried out throughout the current century has improved our understanding of the reproductive biology of ...

Sexual maturity in western Atlantic bluefin tuna [PDF]
Scientific Reports, 2014 We introduce a novel endocrine approach for assessing the unresolved matter of the timing of sexual maturation in western Atlantic bluefin tuna (ABFT), a highly migratory population whose status remains uncertain. Ratios of follicle stimulating hormone to luteinizing hormone, a sexual maturity indicator, in all ABFT ≥ 134 cm curved fork length (CFL ...
