  abstract = {{T}he annual movement of {S}outh {A}frican sardine {S}ardinops sagax up the east coast of {S}outh {A}frica, known as the 'sardine run', was investigated using data from aerial surveys for the period 1988-2005 and compared with remotely sensed sea surface temperature ({SST}) and chlorophyll a data. {S}ardine sighting rates were highest within the {W}aterfall {B}luff {B}ight off the {E}astern {C}ape {C}oast, where conditions appeared to be most favourable. {S}ardine and predator sightings decreased significantly northwards of {M}doni on the {K}wa{Z}ulu-{N}atal ({KZN}) coast, whereas the proportion of nearshore sightings increased. {T}he causal mechanism for this inshore concentration is suggested to be the influx of warm {A}gulhas {C}urrent water from the {D}urban {E}ddy that forces sardine shoreward. {C}ape gannet {M}orus capensis, common dolphin {D}elphinus capensis and sardine distributions were associated, and there was an association between {SST} and sardine and predator distributions. {T}here was a marked increase in bottlenose dolphin {T}ursiops aduncus sightings upon commencement of the sardine run, with these dolphins being considered to be a 'migratory' stock that enters {KZN} waters every winter.},
