Effects of seasonal variability in across- and alongshore transport of anchoveta (Engraulis ringens) larvae on model-based pre-recruitment indices off central Chile

► A hydrodynamic model reproduces seasonal variability of SST and EKE off Chile. ► This coupled to an individual-based model simulates larval transport of anchoveta. ► Pre-recruitment variability to the known historical recruitment zone was reproduced. ► An undocumented pre-recruitment southern zone was found through this modeling study. ► The model configuration and the value of findings are discussed.
