Abstract
The motivation of this thesis was the relationship breakdown of proxy environmental variables to puerulus settlement of the
Western Rock Lobster, Panulirus cygnus, during the late 2000s. The subsequent recovery of pueruli numbers has shown a shift
in settlement patterns northward and later in the season. Larval dispersal modelling suggested that continental shelf processes
during the low settlement period were not conducive to transporting pueruli towards key latitudes along the coast, combined
with sustained low kinetic energy conditions and cooler waters in the South-East Indian Ocean. The relevance of spatial and
temporal scales of oceanographic conditions influencing pueruli is realised.
