Romanov E. V. auteur aut IRD Chassot Emmanuel auteur aut IRD text journalArticle eng text/pdf born digital access Using a genetic marker mitochondrial DNA control region, Nikolic et al. (Environ Biol Fish 99:171-178, 2016) recently reported the identification of two juveniles of tuna as skipjack (Katsuwonus pelamis) recovered from the mouth of dolphinfish in the vicinity of Reunion Island, western Indian Ocean. Based on the age estimates of the two specimens from opercular bones at about 16-20 days and the increased occurrence of skipjack in the catch of Japanese longliners during October-January, the authors indicate that their results suggest a specific seasonal spawning area of skipjack around Reunion Island. We challenge the validity of age estimates and the interpretation of the results published by Nikolic et al. (Environ Biol Fish 99:171-178, 2016). Current knowledge of skipjack tuna biology indicates that the paper of Nikolic et al. (Environ Biol Fish 99:171-178, 2016) contains misinterpretation of field observations that led the authors to misunderstandings on skipjack tuna ecology. specialized Ageing Age validation Growth Scombridae Katsuwonus pelamis OCEAN INDIEN OUEST REUNION 036 034 100 1 85-88 2017 0378-1909 https://www.documentation.ird.fr/hor/fdi:010068762 10.1007/s10641-016-0544-3 0378-1909 [F B010068762] https://www.documentation.ird.fr/hor/fdi:010068762 https://www.documentation.ird.fr/intranet/publi/2017/01/010068762.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2017-02-06 2023-07-11 fdi:010068762 fre
