Abstract
The present models all assume a single southern Benguela sardine population. Is there sufficient evidence to consider as plausible an alternative that there could be two populations, with one distributed more towards the east and of a size that is not trivially small compared to the “conventional” population fished off the west coast? For a two-population scenario, would the May recruit survey be regarded as indexing recruitment for the “west” population only; further, need the model attempt to incorporate spatial distribution shifts over time for the two populations
