“…However, although some fi sh are known to ingest S. thompsoni, its high water content and the variation in biomass by orders of magnitude during the spring/ summer season due to its characteristic alternation of generations rends it a less desirable food item. The pelagic fi sh fauna in the Southern Ocean, a logical alternate source of food, is relatively scarce and only a minor component of the epiplankton of the Antarctic Ocean (Morales-Nin et al, 1995;Hoddell et al, 2000), except in the high latitude regions of the cold continental shelf (high Antarctic) such as the Ross Sea or the southern Weddell Sea, the habitat of the nototheniid Pleuragramma antarcticum. In deeper pelagic waters, (Ͼ500 m) the mesopelagic myctophid E. antarctica is the dominant fi sh (Barrera-Oro, 2002), and is available as prey to diving birds and seals when it migrates into the upper 0-300 m during the night (Robison, 2003;Loots et al, 2007).…”

“…The model analyzed in the discussion is highlighted in bold and shaded Rakovitza glacialis and Pleuragramma antarcticum, were collected during the present survey. The dominance of P. antarcticum larvae often observed in Antarctic shelf and slope waters could be confirmed for the Lazarev Sea (Kaufmann et al 1995, Hoddell et al 2000, Granata 2002). …”

“…Only a few fish surveys have been conducted in the less intensively investigated sectors of the Southern Ocean (Hoddell et al 2000, Granata 2002, Donnelly et al 2004). Our study forms the first published record on the distribution of postlarval fishes in the pelagic waters of the Lazarev Sea and contributes new data on the distribution of fish larvae, 23 yr after the data collection of the most recent published record (Efremenko 1991).…”

“…This pattern reflects the contrast between the shelfassociated species community dominated by notothenioids and the offshore community of mesopelagic fishes in the Southern Ocean (DeWitt 1970, Hoddell et al 2000, Granata 2002). The 6 notothenioid species encountered on the few shelf stations can be considered as a subsample of the coastal ichthyoplankton community of the Lazarev Sea (Efremenko 1991, White & Piatkowski 1993.…”

“…Larvae of Bathylagidae, Myctophidae and Paralepididae are common in oceanic nearsurface waters (Hoddell et al 2000, Fisher et al 2004). In high Antarctic shelf waters, the nototheniid Pleuragramma antarcticum (Antarctic silverfish) is the dominating pelagic species (White & Piatkowski 1993, Hoddell et al 2000. Spatial separation has been hypothesized between the different life stages of P. antarcticum; larvae feed on zooplankton in the surface layer of the shelf waters and move into deeper layers farther offshore when they become juveniles.…”

, respectively. A generalized additive model significantly related the density of postlarval E. antarctica to the abundance of Antarctic krill Euphausia superba, ocean depth and sea surface temperature. The diet of E. antarctica was dominated by copepods and euphausiid larvae. Mean energy density of E. antarctica in the upper 200 m was 2.8 kJ m -2 , which is equivalent to 36% of the energy stored in Antarctic krill stocks and probably would be considerably higher if a greater depth range were considered. This suggests that E. antarctica is a major energy transmitter in the food web of the Lazarev Sea, challenging the classical krill-dominated food web paradigm of the Southern Ocean.

Large submarine plateaus impede the eastward flow of the deep‐reaching Antarctic Circumpolar Current (ACC), and at the southern Kerguelen Plateau (SKP), the ACC flow is steered north through the Fawn Trough and south through the Princess Elizabeth Trough. During the Kerguelen Axis study, a regional‐scale ecosystem survey, oceanographic sampling showed the ACC water properties west of the SKP to be distinct from those over the SKP. Electrona antarctica, a dominant mesopelagic fish species, is associated with Circumpolar Deep Water transported by the ACC, and modified versions that occur over and downstream from the SKP including along the Antarctic continental slope. Here, otolith chemistry from samples of E. antarctica collected during the survey were used to test a biophysical hypothesis predicting structuring and movement between populations along zonal flow in the ACC. In chemistry deposited during early life in the otolith nuclei, the relationship between MgCa−1 and SrCa−1 showed complete separation between fish collected over the SKP and within the ACC proper, indicating population differentiation. Chemistry from the otolith edges, deposited during the period leading up to capture, showed significantly higher concentrations of MgCa−1 over the SKP, likely related to differences in feeding and reproduction. Fish with nucleus chemistry characteristic of the SKP were also found in samples caught further east, suggesting they were transported along the ACC downstream, and southward toward the Antarctic continent within the Australian–Antarctic Gyre.
