A collection of juvenile squid were caught with the Isaacs-Kidd midwater trawl (IKMT) and the Juday plankton net at 86 stations in Prydz Bay (60°–67°30′S, 60°–80°E) to a depth of 500 m but mostly at 0–200 m. Five species were identified, Psychroteuthis glacialis, Alluroteuthis antarcticus, Brachioteuthis sp. and the cranchiids Galiteuthis glacialis and Mesonychoteuthis hamiltoni. P. glacialis and the cranchiids were the most abundant species. Young P. glacialis (5–17 mm ML) were taken at depths of 5–200 m but concentrated in the upper 100 m whilst the cranchiids (5–35 mm ML) occurred over a wider vertical range (50–500 m). The regular occurrence of paralarvae and juveniles suggests that all the species reproduce in the Antarctic. Juvenile Vertical distribution appears to differ between species with P. glacialis concentrated relatively near the surface, the cranchiids in the upper part of the Circumpolar Deep Water and A. antarcticus widely distributed to a depth of 900 m.
