Small pelagic fish species as sardine and anchovy exhibit drastic decadal-scale shifts in abundance in respond to climate variability. Sharpe declines of these fishes have particularly serious commercial and ecological consequences in eastern boundary current ecosystems, where they sustain major world fisheries and represent the forage of a broad variety of predators including larger fish, marine birds and mammals. Understanding the mechanisms and the relations between the different components of the food web by which environmental forcing drive the observed fish variability remains a challenging problem. Attractive and emerging tools for digging into the problem of small pelagics variability are the so-called end-to-end ecosystem models, which combine a circulation model, a lower trophic model component, and an individual-based model for the fish in a single model framework. In this talk I will describe and show the first results of a 50-year end-to-end coupled model simulation for sardine (Sardina pilchardus) and anchovy (Engraulis encrasicolus) in the Canary Current ecosystem (Western Iberia plus NW Africa). I will discuss the ability of such model for capturing decadal cycles of historical landing records, the analytical methodology to unveil the simulated fish response to environmental forcing, as well as point to possible limitations and uncertainties of the approach.
