Abstract

A study for investigating the values of plasma glucose, serum total protein and serum ions  (calcium, potassium, magnesium, sodium and chloride) was carried out in young Colossomoma macropomum Cuvier, 1818, Piaractus mesopotamicus Holmberg, 1887 and the hybrid tambacu (P. mesopotamicus x C. macropomum), kept in intensive system. Glucose concentrations were higher in tambacu than in P. mesopotamicus and C. macropomum. Total protein levels were higher in P. mesopotamicus than both C. macropomum and tambacu. C. macropomum presented higher concentrations of sodium and chloride, while P. mesopotamicus had higher concentrations of potassium and magnesium. However, levels of calcium were similar for the species studied. The hybrid tambacu showed the smallest levels of total protein, and intermediate levels of sodium, potassium, magnesium and chloride, compared to  both P. mesopotamicus and C. macropomum. Baseline values for healthy fish in aquaculture were established, and they may be used for further comparisons in studies with wild populations of P. mesopotamicus and C. macropomum.
