| dc.description.abstract | The gastric content of Notothenia coriiceps neglecta NYBELIN and Notothenia rossii marmorata FISHER collected in two localities around the South Shetlands Islands, Antarctica is studied. To quantify those contents the numerical and frequency methods are used. Sorensen's index of faunistic affinites is applied in order to establish feeding differences among both species and to find out numerically, food competition at localities of capture. Trophic diversity using Margalef's formula (1957) are calculated. The results obtained suggest a relationship between competition for food and trophic diversity. The Chile bay could be characterized by a high competition and low trophic diversity while in Fildes bay a low competition for food and a high trophic diversity has been detected. | es_ES |
