AbstractThe eastward current at the Strait of Gibraltar (the Atlantic Jet) fertilizes the southwestern Mediterranean and it is the responsible for the comparatively high fish landing of this region. However, we demonstrate in this communication that the high kinetic energy of this current negatively impacts the recruitment of anchovy owing to the advection and dispersion of larvae and post-larvae. The inhibitory effect of kinetic energy on anchovy landings is not a transient but a persistent state. Only an exceptional combination of events can release anchovy recruitment from this inhibition to create landing outbreaks. As such, the dynamics of anchovy in the Alborán Sea is more akin to a pest than to a standard fishery. We disentangle here what are these events and their high sensitivity to climatic fluctuations.
