DOI : 10.4194/1303-2712-v15_1_04 Viewed : 1334 - Downloaded : 805 This study aimed to evaluate the nutritional qualities of selected commercial fish meals (FM) in diets of juvenile shi drum, Umbrina cirrosa L..The five FMs diets based on two Peruvian anchovy meals (one is a flame dried FM: Peru-1 and the other steam-dried FM: Peru-2), a Danish low-temperature FM (Danish LT), a domestic anchovy LT meal (Domestic LT) and an Alaskan white FM (WFM) as major protein source were formulated to contain 56% protein. The diets were fed to triplicated groups of fish with initial average weight 25.06±0.11 g for 7 weeks. Fish on Peru-2 diet performed better than those on WFM in terms of final weight and specific growth rate. These fish were also significantly better regarding nutrient utilization efficiency than those fed WFM and Peru-1 diets, but similar to those on Danish LT and Domestic LT. WFM diet fed fish had significantly less amount of body lipid than those fed Danish LT diet and retained lower lipid than the other groups of fish. The results indicate that different commercial sources of FMs do not have an equal nutritional value for juvenile shi drum, an important finding that should be considered in future studies.
