“…Recent warming has brought dramatic changes to the region including an increase in ice melting recorded in ice core data (Abram et al, 2013), the disappearance of ice shelves (Vaughan and Doake, 1996;Rott et al, 1996;Hodgson et. al., 2011), changes in ocean circulation (Jourdain et al, 2017), the retreat of tidewater glaciers (Cook et al, 2005) and sea ice (Cavalieri and Parkinson, 2008;Jourdain et al, 2017), and changes in regional ecology and ecosystems (Moline et al, 2008;Montes-Hugo et al, 2009;Mintenbeck and Torres, 2017;Amesbury et al, 2017). The retreat of glaciers due to both warming and the breakup of ice shelves reflects an increase in the regional rate of mass loss (Rignot et al, 2008).…”

“…Because of the influence of sea ice on silverfish biology (Vacchi et al . 2012b), future changes in sea-ice dynamics in Ross Sea may impact spawning success and abundance of silverfish (La Mesa & Eastman 2012, Mintenbeck & Torres 2017). As silverfish are a keystone species, these changes may affect the entire Ross Sea ecosystem (Smith et al .…”

Acoustic deployments reveal Antarctic silverfish under ice in the Ross Sea

et al. 2018

Antarctic silverfish (Pleuragramma antarctica Boulenger) are a keystone species in the Ross Sea. Silverfish eggs and larvae are abundant during spring amongst the sub-surface platelet ice in Terra Nova Bay. It is not known whether the eggs are spawned elsewhere and accumulate under the ice or whether there is mass migration of silverfish to coastal spawning sites in winter. To test the latter hypothesis, an upward-looking 67 kHz echo sounder was moored in Terra Nova Bay to observe potential silverfish migration. The echo sounder was deployed at 380 m in a seabed depth of 550 m and ran for 210 days from 15 May until 11 December 2015. Acoustic reflections consistent with silverfish were observed at depths of 230–380 m during 9–22 September. This timing is consistent with the presence of eggs typically observed in October. Adult silverfish were also detected with an echo sounder and camera deployed through the ice in McMurdo Sound on 10 November 2015. Juvenile silverfish, but not adults, were observed through the ice in Terra Nova Bay during 11–16 November 2017. This paper provides a proof of concept, showing that innovative use of acoustics may help fill important observation gaps in the life history of silverfish.

“…The phytoplankton community shifts during warmer years with low sea ice 12,49 , potentially altering copepod abundance and composition 50 . In addition to the physiological cost of warmer waters on larval Antarctic Silver sh, climate change could cause their hatching period to become out of sync with peak abundances of their prey 11,19,51 .…”

“…Between 1979 and 2018, annual sea ice duration along the WAP decreased by about 2 months 12 . Therefore, recent declines in sea ice and thus spawning habitat has been implicated in diminished Antarctic Silver sh abundance in the WAP region 11,[13][14][15][16][17][18][19] . However, abundance data of su cient temporal and spatial scale for Antarctic Silver sh was previously unavailable to test this hypothesis.…”

Climate drives long-term change in Antarctic Silverfish along the western Antarctic Peninsula

Over the last half of the 20th century, the western Antarctic Peninsula has been one of the most rapidly warming regions on Earth, leading to substantial reductions in regional sea ice coverage. These changes are modulated by atmospheric forcing, including the Amundsen Sea Low (ASL) pressure system. We utilized a novel 25-year (1993–2017) time series to model the effects of environmental variability on larvae of a keystone species, the Antarctic Silverfish (Pleuragramma antarctica). Antarctic Silverfish use sea ice as spawning habitat and are important prey for penguins and other predators. We show that warmer sea surface temperature and decreased sea ice negatively impact larval abundance. Modulating both sea surface temperature and sea ice is ASL variability, where a strong ASL is associated with reduced larvae. These findings support a narrow sea ice and temperature tolerance for adult and larval fish. Further regional warming predicted to occur during the 21st century could displace fish populations, altering this pelagic ecosystem.
