Multi-scale variability in the biomass dynamics of the north-central stock of the Peruvian anchoveta (1953-2022) within the Humboldt Current System

Historical conference contribution on anchoveta biomass variability across multiple temporal scales.

Open Science Conference on Eastern Boundary Upwelling Systems: Past, Present and Future and Second International Conference on the Humboldt Current System

Overview

This conference contribution examined variability in the biomass of the north-central Peruvian anchoveta stock from interannual to multi-decadal scales. The analysis was intended to distinguish short-term fluctuations from longer-term structural changes within the Humboldt Current System.

Main contribution

  • characterization of biomass variability across multiple temporal scales;
  • separation of short-term fluctuations from persistent changes in stock magnitude;
  • interpretation of long-term anchoveta dynamics within an eastern boundary upwelling system;
  • implications for monitoring, assessment, and management under strong environmental variability.
