abstract = "It has been reported that sea surface temperature (SST) anomalies,
flow intensity and mesoscale ocean processes, all affect sardine
production, both in eastern and western boundary current systems.
Here we tested the hypothesis whether extreme high and low
commercial landings of the Brazilian sardine fisheries in the
South Brazil Bight (SBB) are sensitive to different oceanic
conditions. An ocean model (ROMS) and an individual based model
(Ichthyop) were used to assess the relationship between oceanic
conditions during the spawning season and commercial landings of
the Brazilian sardine one year later. Model output was compared
with remote sensing and analysis data showing good consistency.
Simulations indicate that mortality of eggs and larvae by low
temperature prior to maximum and minimum landings are
significantly higher than mortality caused by offshore advection.
However, when periods of maximum and minimum sardine landings are
compared with respect to these causes of mortality no significant
differences were detected. Results indicate that mortality caused
by prevailing oceanic conditions at early life stages alone can
not be invoked to explain the observed extreme commercial landings
of the Brazilian sardine. Likely influencing factors include
starvation and predation interacting with the strategy of spawning
