Loricariichthys anus (Viola) is currently the largest fish species of economic value of Mangueira Lagoon and, because of that, the aim of this work was to analyze its body yield and the chemical composition of its fillet. Forty animals caught in Mangueira Lagoon were divided into two groups of 20 animals each. The weight presented a variation of 128 to 190g in group A and of 234 to 293g in group B. Biometric evaluation was performed in Ichthyology Laboratory of UFPEL, where the animals were evaluated regarding length and weight, which were used for body yield calculation. Carcass yield, head yield, visceral yield, skin yield, clean trunk yield and fillet yield were evaluated. Chemical analysis was performed in dried fillet to obtain the values of protein, lipids, ash and moisture, and in natural matter to assess the fatty acid content. The weight of animals affects carcass yield. The viola fillet is lean, with high protein content and higher amount of unsaturated fatty acids compared to saturated.
