【 摘 要 】

- The influence of the substitution of soybean meal protein (SM) by canola meal protein (CM) inProchilodus lineatus fingerling diets was verified. One hundred and twenty specimens, averaging weight 1.88±0.82g and total length 5.40±0.99cm, was assigned to a completely randomized randomized design, with six treatments and four replicates, in a 50 L glass aquarium, with five fingerlings in each experimental unit. Isoprotein (26.00%), isocalcium (0.90%) and isophosphorus (0.70%) diets were formulated with increasing replacement levels of SM protein by CM protein (0.00, 20.00, 40.00, 60.00, 80.00, and 100.00%). Values correspond respectively to 0.00, 8.03, 16.10, 24.10, 32.15 and 43.12% of CM inclusion in diets for 30 days. Physical and chemical parameters of water were measured every seven days. Through an increase in CM inclusion in diets, a linear decrease in weight gain and protein efficiency rate was reported; a linear increase in food conversion has also been recorded. There was no influence of CM inclusion in diets on survival rate and feed costs/kg gained. Water temperature, pH and electrical conductivity remained within proper limits. Increase in levels of protein inclusion of CM in diets for Prochilodus lineatus fingerlings caused a decrease in their performance.
