PROCESSING YELD AND PROXIMATE COMPOSITION OF Rhamdia voulezi FILLETS

Abstract The aim of this study was evaluate the effect of slaughter weight and sex on processing yield and on the proximate composition of Rhamdia voulezi. We calculated the percentage yield of the whole fish (carcass, clean trunk, abdominal muscle, fillet, edible parts, head, skin, gonads and visceral fat yield). There was no statistical difference in yields among weight classes (P>0.05). However, when assessing the income between sexes we observed significant difference (P0.05) among the classes, however, moisture, lipids and calories had significant difference (P
