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

Published in Open Science Conference on Eastern Boundary Upwelling Systems: Past, Present and Future and Second International Conference on the Humboldt Current System, 2022

Overview

This conference contribution examines variability in the biomass of the north-central Peruvian anchovy stock from interannual to multi-decadal scales. The analysis is 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 anchovy dynamics within an eastern boundary upwelling system.
  • Implications for monitoring, assessment, and management under strong environmental variability.
