General ecology of coastal fish from the South Shetland Island and west Antarctic Peninsula areas
There is a lower diversity of Antarctic fish species on the continental shelves (139 spp) compared with other cold-water seas (> 350 spp in the North Atlantic). However, although the diversity of the notothenioids is limited compared with the large size of the ecosystem, there is no other fish gr...

There is a lower diversity of Antarctic fish species on the continental shelves (139 spp) compared with other cold-water seas (> 350 spp in the North Atlantic). However, although the diversity of the notothenioids is limited compared with the large size of the ecosystem, there is no other fish group in the world with such a diversification and dominance in a continental shelf habitat (Eastman 1995). The role of fish as predators and prey in the Antarctic marine ecosystem is important for understanding energy flow from benthos and pelagic nekton, such as Antarctic krill, to predatory seals and penguins, and for understanding the potential for fisheries. This matter has been the object of several studies during the last three decades (reviewed in Kock 1992; Hureau 1994; Barrera-Oro 2002).
