In Mexico, the "charal" fish Chirostoma spp. is grouped in five species: Chirostoma grandocule, Chirostoma patzcuaro, Chirostoma humboltianum, Chirostoma attenuatum and Chirostomajordani which live in lakes in the country, and they are not consumed or their demand is low The objective of this research was to analyze the macronutrients of Chirostomajordani charal and inform population their nutritional value to increase human nutrition. Sampling was provided at Xochimilco channels in Xochimilco, D.F., summer and winter seasons at 2009. Fish (200 g) were maintained in channels water for proximal analysis according AOAC methods (1995). The results in dry bases were: protein 74.36%, lipids 1.24%, fiber 0.27%, minerals 4.9%, and soluble carbohydrates 19.23%. This fish grants protein, plastic material essential for human development: its lipid and carbohydrate contents, sources of energy, are low; however, the excess of disseminated proteins increase the energy sources. Fiber is found in a minimum amount. Dehydrated charales may be stored without refrigeration up to 3 months, maintaining their nutritional value. Consumption of the charal should be considered in the basic diet for its nutritional properties, to diminish malnutrition in the Mexico and other countries.展开更多
