Our understanding of the biology of Atlantic bluefin tuna (Thunnus thynnus) has in- creased profoundly in the last decade, and the progress is attributed to the development and application of a variety of novel tools. Here we provide a comprehensive examina- tion of available data on the life history and stock structure of T. thynnus by re-examining current databases and literature and highlighting findings from recent studies using ap- proaches such as archival tags and natural markers (e.g., genetics, otolith chemistry). The present review provides a detailed synthesis on the reproductive biology, feeding ecology, growth, mortality, migration, and stock structure of T. thynnus. In addition to characterizing key life history attributes and discussing stock-specific (east versus west)differences, the implication of trans-Atlantic movement and mixing are addressed. We also identify significant data needs that still exist and must be addressed to promote effective management and rapid recovery of T. thynnus populations.

Abstract
Our understanding of the biology of Atlantic bluefin tuna (Thunnus thynnus) has in- creased profoundly in the last decade, and the progress is attributed to the development and application of a variety of novel tools. Here we provide a comprehensive examina- tion of available data on the life history and stock structure of T. thynnus by re-examining current databases and literature and highlighting findings from recent studies using ap- proaches such as archival tags and natural markers (e.g., genetics, otolith chemistry). The present review provides a detailed synthesis on the reproductive biology, feeding ecology, growth, mortality, migration, and stock structure of T. thynnus. In addition to characterizing key life history attributes and discussing stock-specific (east versus west)differences, the implication of trans-Atlantic movement and mixing are addressed. We also identify significant data needs that still exist and must be addressed to promote effective management and rapid recovery of T. thynnus populations.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
