2015 Aquatic Sciences Meeting
Aquatic Sciences: Global And Regional Perspectives — North Meets South
22-27 February 2015
Commercially valuable tunas have preferred habitat ranges. The preferred habitats of tuna species are subject to spatial shifts due to climate change. In fact, some local studies in the north Atlantic suggest that the distribution ranges might be shifting towards higher latitudes. In this study we analyze whether this is a global pattern for commercially valuable tunas. We use two main sources of information: on one hand, we use pelagic longline catch per unit of effort data as a proxy for tuna abundance, and on the other hand, we use habitat models to predict the temporal evolution of the optimum habitat distribution. Results are summarized regionally as well as taxonomically.
