Schematic of two alternative spawning and recruitment scenarios that can both generate concordance in recruitment across the region. (a) Spawning occurs generally across the region and then recruitment is maintained in all shelf regions. (b) Spawning and successful survival during the first year occur mainly in central and southern areas of the Scotia Sea, and the year class is dispersed through interactions with the ocean and sea ice over the next 1–2 years. Intermediate scenarios between these extremes can also be envisaged.
