An analysis of the concentrailons of potassiurn, sodium. calcium. magnesiurn. tron, proteíns and fat, was made in the muscular tissue of the líned catftsh PseUliop laiystomajasciatLtm from the middle Orlnoco in Venezuela, as a contribution to the knowledge of the ecofisiology of the species and of its importance from the nutritious point of view. The salts were analyzed by Espectrofotometria of Atomic Absorption with fIame of air-acetylene and correction of deuterium bottom, using a tearn Perkin Elmer 3100 coupled with al1 automueslreador Perkin-Elmer ACE-51. The percentages of proteins and fat were determined by the method ofWeede (Omcial Methods of Analysis,AOAC).An average 26,03 jo 5,08 pg/ g was determined in to be from concentration. 387,05 jo 33,38pg/gin the concentration of calcium, 951,00 jo 236.04 pg/g In the concentration of magnesium, 1386,73 jo 47.39 pg/g in the concentration of sodium. and 11626.41 jo 365,23 pg/ g in the concentration of potassium. The average ín the concentration ofproteíns was of 18.1 jo 0,12% and that of fat 0.85 jo 0.03%

Concentration of K, Na, Ca, Mg, Fe, proteins and fatty in the lined catfish Pseudoplatystoma fasciatum of tbe middle Orinoco in Venezuela
