The evolution of fisheries in Portugal: A methodological reappraisal with insights from economics (original) (raw)

Interpretation of fisheries data can be considerably affected by missing or naïve analyses of economic variables. We analyze the case of Portugal, showing how considering the effects of inflation reverses previous conclusions regarding the evolution of fish prices and revenues (fisheries performance). We further emphasize the importance of variables related to economic drivers, such as the prices of substitute goods for understanding the demand for fish, and of exchange rates as a determinant of fish imports. We call for a stronger contribution from economics and greater interdisciplinary scrutiny of a crosscutting scientific area such as fisheries research.
