Resumen:
The relationship between SST data
obtained from MODIS sensor and the seasonal (spring) distribution pattern of
Argentine hake in the San Matías Gulf basin is analyzed. Hake abundance indexes
(CPUE) and temperature in the water column were obtained during a research
survey with bottom trawl net. Satellite SST data were validated with in situ
(CTD) observations and correlated with hake abundance indexes. Hake abundance
showed positive correlation with SST and higher densities of fishes were
observed in areas with high water stratification. The distribution pattern of
hake in San Matías Gulf during spring months appears related to the existence
of a cyclonic gyre and a frontal system which, in combination, would produce
favorable conditions to the spawning process of Argentine hake
