Resumen:
The relationship between SST sateIlite data
and the distribution pattern of Argentine hake during
spawning season in the San Matías Gulf was analyzed.
Data of hake abundanee and temperature in the water
eolumn were obtained during a researeh survey with
bottom trawl net. SST data obtained from MODIS
sensor were validated with in silu observations and
eorrelated with hake abundanee indexes. Hake
abundanee showed positive eorrelation with SST and
higher hake densities were observed in areas with high
stratifieation in the water eolumn. The spatial pattern of
hake distribution during the reproduetive season
appears strongly related to a eyclonie gyre whieh would
produce favorable eonditions for the spawning proeess
and the development of hake early stages.in silu observations and
