Tambaqui (Colossoma macropomum) is an omnivorous fish, native to the
Amazon drain basin and present high commercial value. Rusticity and high
productive are characteristics that make the species interesting for culture.
However, in commercial fish culture, the feeding costs can represent 50 to 70%
of the total production costs and the protein is the most expensive nutrient of
the diet. Fish meal has been used traditionally as protein source in fish feeds,
but the high cost of this product has motivated the study of altemative protein
sources. The objective of this work was to evaluate the effects of partia1
replacement of fish meal protein (FP) by the leucena leaf meal protein (FFL) in
diets for juvenile tambaqui (Colossoma macropomum). A total of 240 juvenile
were distributed in 12 plastic boxes (350 L) in a completely randomized design
with four treatments (O%, 7%, 14%, 21% replacement of the fish meal protein
by the leucena leaf protein) and three replicates. Fish body protein
concentration, feed conversion ratio, weight gain and water physicochemical
parameters were analyzed. No significant difference (p>0,05) was found for all
parameters among treatments, indicating that it is possible to replace 21% of
FP by the FFL in rations for juvenile tambaqui. |
