摘要

The freshwater shrimp Macrobrachium jelskii is a very abundant resource in the zone of the Delta of the Orinoco, with ability to reproduce in culture lagoons and without useful at the present time. In the present investigation the content of protein, carbohydrates, lipids and fatty acids of this shrimp, was analyzed under culture conditions, with the purpose of quantifying and categorizate its bromatological composition, and thus defining its possible industrial advantage, like raw material for the concentrated food elaboration for animals. The protein analyses, carbohydrates and lipids, were made through espectrophotometric methods and the fatty acid profile was determined by gas chromatography connected to spectrometry of masses. The analyses determined that the concentrations of proteins, total carbohydrates and lipids, on the basis of dry mass, were increased during the development of the investigation, varying their contents from 34,742,39 to 57,705,75%; from 0,64 0,07 to 3,430,40% and 9,900,9 to 11,401,30%, respectively. The values of fatty acids obtained in M. jelskii , varied between 35,93 51,42% for the saturated; 21,00 25,49% for monounsaturated and 23,09 38,8% for poliunsaturated. Finally, it is important to emphasize that the culture of M. jelskii in fish cultured lagoons, maintained with food of low cost, allows to obtain biomass with high nutritional content, which could be used as ingredient for the concentrated food formulation for fish and crustaceans in aquaculture
