Abstract
Summary.The iced storage characteristics of three Bolivian freshwater fish species from the Altiplano region were monitored using chemical, microbiological and sensorial methods. Fish studied were: pejerrey (Busilichthys bonariensis) captured in two locations, Lake Poopo and Lake Angostura; trout (Sulmo gairdneri) from Lake Titi‐caca and carp (Cyprinus carpio) from Lake Angostura. The proximate composition and physical nature of these fish are presented. The shelf lives of these species, as deter‐mined by both sensory and microbiological evaluations, were found to be: pejerrey from Lake Poopo: 20–21 days, pejerrey from Lake Angostura: 15‐19 days, carp from Lake Angostura 17–20 days and trout from Lake Titicaca: 15–18 days. The value of the various methods used to monitor quality changes are discussed.
