AB  - A 45 day feed study aimed to evaluate the
effects of cornmeal and in natura mango at different
concentrations of carbohydrates and proteins on
performance, hematology, metabolism and digestive
enzymes of tambqui, <i>Colossoma macropomum</i>. In the
experiment, 144 juveniles were randomly distributed in a
factorial scheme where eight experimental diets (C30P30,
C36P28, C42P26, C48P24, M30P30, M36P28, M42P26
and M48P24) were tested for 45 days. Performance
parameters, hematological indices, metabolites and
digestive enzyme activity were evaluated. The best
performance was observed in the fish that received the
diet C42P26 with cornmeal as a carbohydrate source. The
results of glucose, triglycerides and total plasma protein
had a significant effect on levels, source and interaction
effect. The levels of triglycerides and cholesterol were
higher in the diets with fresh mango. The activity of the
enzyme glutamate dehydrogenase presented variations,
modulated from the carbohydrate and protein
concentrations of the diet. The digestive enzymes activity
adapted to the profile of the diets tested and were not
related to fish performance. It is concluded that
cornmeal diet (C42P26) is the best source of
carbohydrate, promoting better performanceand health of
<i>C. macropomum</i>.
