  abstract = {{A}long the coast of {N}orth-{W}est {A}frica, fish supply is important at both socio-economic and cultural levels. {R}eports by fishermen emphasise changes in the distribution of fish species important for food security. {N}orthward shifts in the distribution of sardinella and other species have been attributed to a warming trend and the redistribution of upwelling intensity and productivity. {A}s a result, the abundance of sardinella along the coast has increased in the subtropics and fallen in the intertropical region. {I}ndependent observational time series confirm a robust northward shift in {S}ardinella aurita since 1995, which we attribute to the intense warming of this region, where the greatest increase in sea surface temperature of all tropical regions is found. {T}he spatial shifts in biomass of several hundred kilometres observed during the last 20 years are of the same order of magnitude as those recorded for surface isotherms in the sub-regional pelagic habitat of sardinella. {S}uch changes are an important policy consideration for food security management in several {W}est {A}frican countries.},
