Small pelagic fish (SPF) present relatively short life cycles, with fast growth, high mobility and plankton-base feeding. Therefore, they are highly sensitive to fluctuations in environmental conditions, including those related to Climate Change, and fishing. On the one hand, reproductive traits have been recently described for all these species in the Canary archipelago, which show a clear decreasing pattern of their sizes at first maturity during the last years (Jurado-Ruzafa et al., 2021). On the other hand, a regional increase in the sea water temperature has been observed in NW African waters during last decades (Vélez-Belchí et al., 2015). Foreseeing potential variations in the life history traits of SPF is critical for effective management measures in the current Global Warming scenario.
