CONTRIBUTION OF POLYCHAETES (ANNELIDA: POLYCHAETA) IN THE DIET OF THREE NOTOTHENIOIDS SPECIES (PERCIFORMES: NOTOTHENIOIDEI) FROM THE MAGELLAN REGION

The importance of polychaeta in the diet of three notothenioids of western Patagonia we determined. By summarizing information published, regarding Patagonotothen tessellata, P. cornucola and Harpagifer bispinis. An analysis of the percentage frequency of occurrence and numerical was performed, cons...

An analysis of the percentage frequency of occurrence and numerical was performed, considering also the selectivity of prey by size. Nereid polychaeta were the only prey item present in all samples taken, showing high values in percentage frequency of occurrence in the Capitán Aracena Island (72.2%) and 46.2% in Puerto Williams referring P. tessellata and H. bispinis respectively. While for P. cornucola, Nereidae exhibited a frequency of occurrence in Puerto Riquelme of 5.9% and 13.6% in Puerto Williams.
