| dc.description.abstract | The gravity model of explicit spatial movement for the two South African hake species is extended to take account of advice from a mini-task group as on the plausibility of some earlier estimates of movement proportions and to incorporate information from the a GeoPop model to hake survey information over the 1998-2012 period. Addition of the GeoPop data leads to increasing M. capensis but decreasing M. paradoxus estimates of abundance over recent years. There is little impact on nearly all estimates of movement parameters. | en_ZA |
