abstract = "An Individual Based Model (IBM), coupled with a hydrodynamic model
(ROMS), was used to investigate the spawning strategies and larval
survival of the Brazilian Sardine in the South Brazil Bight (SBB).
ROMS solutions were compared with satellite and field data to
assess their representation of the physical environment. Two
spawning experiments were performed for the summer along six
years, coincident with ichthyoplankton survey cruises. In the
first one, eggs were released in spawning habitats inferred from a
spatial model. The second experiment simulated a random spawning
to test the null hypothesis that there are no preferred spawning
sites. Releasing eggs in the predefined spawning habitats
increases larval survival, suggesting that the central-southern
part of the SBB is more suitable for larvae development because of
its thermodynamic characteristics. The Brazilian sardine is also
capable of exploring suitable areas for spawning, according to the
interannual variability of the SBB. The influence of water
temperature, the presence of Cape Frio upwelling, and surface
circulation on the spawning process was tested. The Cape Frio
upwelling plays an important role in the modulation of Brazilian
sardine spawning zones over SBB because of its lower than average
water temperature. This has a direct influence on larval survival
and on the interannual variability of the Brazilian sardine
spawning process. The hydrodynamic condition is crucial in
determining the central-southern part of SBB as the most suitable
place for spawning because it enhances simulated coastal retention
of larvae. © 2014 Elsevier Ltd.",
