| Abstract | The experiment was carried out in the Aquaculture Laboratory of State University of Maringa with the objective of evaluating the ideal ration levels for grass carp fingerlings. Eighty fingerlings were used, with initial medium weight of 0.73 ± 0.10 g and initial medium length of 4.4 ± 0.22 cm, divided in 16 net-cages distributed in four ponds (1,000 L), with five fish each. The design was completely randomized with four treatments and four replications (1, 3, 5 and 7% of the fish biomass). The evaluated parameters were final mean weight (FW), weight gain (WG), feed conversion (FC), final mean length (FL), uniformity (UNI) and survival (S). The (FC) and (WG) presented quadratic relation (P 0.05) between the treatments. Physical and chemical parameters remained within appropriate limits. It was possible to conclude that ration distribution in a proportion of 6.0% of the fish biomass for grass carp fingerlings is appropriate to a better development and survival in an average temperature of 26°C. |
