| Different proteic sources were evaluated for curimba fingerlings (Prochilodus lineatus) to check performance and economical viability for fingerlings with an average weight of 10.47 ± 2.11g and a total initial length of 8.85 ± 0.64 cm, distributed in a completely randomized design with four treatments and four replications, in sixteen 1,000L ponds. Soybean meal + fish meal (SM + FM); soybean meal (SM); SM + canola meal (SM + CM) and SM + dry yeast (DY), with inclusion levels of FM, CM and DY of 19.60%, 32.00% and 39.20% respectively, corresponding to 50.55%, 48.19% and 61.30% of crude protein substitution by FM, CM and DY respectively, were used. There were no significant differences (P > 0.01) for survival and ration R$/gain kg... |
