The Optimal Environmental Window Hypothesis in the ICES Area: The example of the Iberian Sardine

In upwelling areas, the relationship between upwelling intensity and pelagic fish recruitment success appears to be sometimes positively and sometimes negatively correlated. The Optimal Environmemal Window (OEW) hypothesis offers an interpretation for these apparently contradictory results. The OEW...
