GUZMAN, Jonathan A  and  SIELFELD, Walter. DIET OF ORESTIAS AGASSII (CUVIER & VAIENCIENNES, 1846) (TELEOSTEI: CYPRINIDONTIDAE) OF "EL HUASCO" SALT LAKE, HIGH ANDES OF NORTHERN CHILE. Gayana (Concepc.) [online]. 2009, vol.73, n.1, pp.17-27. ISSN 0717-652X.  http://dx.doi.org/10.4067/S0717-65382009000100004.

The diet of Orestias agassii from fresh water springs associated to El Huasco Salt Lake were studied. Lhe stomachs analysis indicated depredation on Ostracoda, Cladocera, Amphipoda, Díptera, Copepoda, Mollusca, Coleóptera, Acari and macrofites. It is concluded that O. agassii is an active carnivore in freshwater communities of the South-American altiplano.
