Environmental variability and fishing effects on the Pacific sardine fisheries in the Gulf of California.

The magenta policy is the reactive policy (fishers increasing total effort when catch is low, decreasing to the minimum encountered in the data if the annual yield is negative). Our work highlights a new framework that embraces the complex processes that drive fisheries population dynamics yet produces simple and robust advice to ensure long-term sustainable fisheries. Our work thusoffersaninsightintoanewframeworkforfisheriesmanagement based on embracing the complex processes that drive population dynamics yet producing relatively simple and robust policies.
