The article led by the PhD candidate Juliano Coletto applied stable isotope analysis to study skipjack tuna diet and migration in the southwestern Atlantic. “Our study generated relevant information for the management for this relevant fishery resource” explains Juliano. Besides quantifying diet composition, the results indicate a residence time in the southern feeding grounds for a few months, and also seasonal movement following the Subtropical Convergence Area dynamic in this region.
The paper had the international collaboration of Dr. Seth Newsome – University of New Mexico. “Dr Newsome’s collaboration in this study was essential to extract the most of the information from the data, and also for the student’s learning”, explains Dra. Silvina Botta, co-author of the study and Juliano’s co-supervisor.
The paper is a contribution from Projeto Bonito, which was coordinated by Dr. Lauro Madureira, and was supported by Consent Decree/Conduct Adjustment Agreement between Petrorio and the Brazilian Ministry for the Environment, implemented by the Brazilian Biodiversity Fund - FUNBIO.
