While this widely distributed, temperate-water species is usually characterized as a coastal bentho-pelagic species, it also occurs well off the continental shelf and behaves as an oceanic-pelagic species. Experience with stock assessment of the species off southern Australia has demonstrated that the application of spatially aggregated models can lead to highly uncertain results, despite the availability of catch data covering the 70-year history of the fishery, catch per unit effort data for part of th..
