Recruitment processes in the larval phase: the influence of varying transport on cod and sprat larval survival
The major aim of the present study was to investigate the influence of varying transport regimes on larval survival and subsequent recruitment of two major Baltic fish species, cod and sprat. A three-dimensional eddy resolving baroclinic model of the Baltic Sea in combination with a Lagrangian particle tracking technique has been used to model larval drift. New results on larval ecology and transport related survival rates were coupled to the transport model to develop an Individual-based Model of larval survival. A first set-up and utilization of this hydrodynamic/ trophodynamic IBM for cod larvae resulted in new insights in the cod recruitment process.
