Gentoo penguin Pygoscelis papua diet as an indicator of planktonic availability in the Kerguelen Islands
Abstract: Since penguins rely on the main planktonic resources of the Southern Ocean, knowledge ... of their diet may be used for monitoring these resources. During winter and spring of 1987 and 1989 ... , we investigated the composition of the diet of gentoo penguins, Pygoscelis papua, in relation to ... changes in the availability of two prey species, Euphausia vallentini and Themisto gaudichaudii, sampled ...

Distribution of krill (Euphausia superba Dana) catches in the South Shetlands and South Orkneys
Abstract: Zones of 20 km width are defined around selected colonies of penguins distributed ... around the coasts of the South Shetland and South Orkney Islands. Krill catches in these zones are shown ... , probably as a result of more variable hydrographic conditions. About 50% of the catch in Subarea 48.1 from ... December to March was taken within 40 km of the coast, and 90% within 80 km in all years 1988-1990. In 1987 ...

Integrated environment–prey–predator interactions off South Georgia: implications for management of fisheries
Abstract: The oceanography of the South Georgia region is principally that of the Southern Ocean ... rather than the South Atlantic. A combination of factors, including advection, local bathymetry and high ... local productivity, leads to relatively large concentrations of krill (Euphausia superba) in the region ... and this is a food source for large populations of penguins and seals that breed at South Georgia.
