Efeito da utilização do subproduto de uva na alimentação de alevinos de piava (leporinus obtusidens)

Abstract

In this study we seek to use the grape residues that were discarded and not used in order to provide a destiny that could contribute economically to the fish feeding by increasing productivity and reducing costs. It was studied the effect of four levels of grape byproduct instead of corn (0%, 25%, 50%, 75%) on the animals zootechnical performance. The experiment was conducted at the Laboratory of Aquaculture and Fish Farming - LAPA at the Federal University of Pampa, campus Dom Pedrito. It was used 80 piava fingerlings, divided into 8 experimental units, with the average weight of 3.37 ± 0.47 g. The experimental design was the completely randomized with 4 treatments and 2 replications. The statistical package used was SAS (2011). It was observed during the experimental period there was a significant effect (P <0.05) on the performance of fingerlings chirped when fed grape byproducts, final weight and ADG where it was observed that up to 50% inclusion can be used for lossless fry. Factor for biomass and body condition, there was no significant difference between treatments with different inclusions byproduct of grape. It is also important to note that survival was 100% in all treatments.
