More Info


Known from off Tasmania and Victoria; elsewhere the species occurs in New Zealand. The Seamount Rudderfish is mostly known from deep offshore plateaus and seamounts. Juveniles less than 10 cm SL occur in epipelagic waters at 30–50 m depth; larger individuals up to 56 cm SL are mesopelagic at 525–1438 m. 


As Tubbia sp in Daley et al 1997 - SE Fishery Quota Species ID Guide.


Named in honour of New Zealand ichthyologist, Andrew Stewart, whose efforts in building a substantial collection of stromateoid fishes from the region has contributed so significantly to our understanding of the life histories and composition of this poorly known group of fishes in the Southern Hemisphere. (Last et al. 2013)
