Doryteuthis (Loligo) gahi is the second most important cephalopod species in the SW
Atlantic from a fisheries point of view. This species and hence, the fisheries profitability
and sustainability, are subject to large inter-annual variability in recruitment strength,
mainly due to interannual and seasonal variations of the Falkland/Malvinas Current. In
this working document we analyse the environmental, geographical, temporal and
physical factors affecting the distribution (abundance) of D. gahi in two areas where its
abundance is highest, using geographic information systems tools. We found a slight
positive correlation between CPUE and longitude, as well as between CPUE and depth
in the northern area, but no correlations could be found between SST and the other
explanatory variables. Regarding the southern area in summer-autumn, we found that
CPUE increases with longitude as we go to the east, and with latitude. We also found
positive correlations between SST and CPUE, as well as with depth. In winter spring
our study revealed a slight relationship between CPUE and location, and with depth
