New data on Martialia hyadesi feeding in the Scotia Sea during winter; with emphasis on seasonal and annual variability
AbstractThe diet of the seven star flying squid, Martialia hyadesi, from the South Georgia sector of the Scotia Sea was described from stomach contents collected in winter (June) 2001. Diet was dominated by the hyperiid amphipod, Themisto gaudichaudii, fish (nine species, mainly myctophids) and cephalopods (mainly cannibalism). The absence of krill, Euphausia superba, and the presence of larger myctophids in the diet are discussed in terms of seasonal and annual prey availability.
