Environmental Factors Changes and Its Association with the Catches Fluctuations of Atlantic Chub Mackerel (Scomber colias, Gmelin, 1789) in the South Alboran Sea (Western Mediterranean Sea)

Based on data from 37 years of catches and environmental satellites in addition to model observations from 1983 to 2020, this study assessed the potential impact of changing oceanographic conditions on the Atlantic chub mackerel (Scomber colias) population in the southern Alboran Sea. To determine t...

Sumario:Based on data from 37 years of catches and environmental satellites in addition to model observations from 1983 to 2020, this study assessed the potential impact of changing oceanographic conditions on the Atlantic chub mackerel (Scomber colias) population in the southern Alboran Sea. To determine the best potential predictors, as well as building the best models to explain the variation of this species's abundance, forward stepwise regression was applied to environmental predictors, viz. sea surface salinity (SSS), sea surface temperature (SST), surface chlorophyll a (Chl-a), U and V wind components, NAO index, and the velocity of Atlantic jets represented by sea level difference (SLD). Then, linear models (LMs) were built and ranked by their AICc values to choose the best predictive models.
