and corn. 7 experimental diets prepared. Amount of carbohydrate materials replacement in diets
were: 1) 100% bread wastes 2) 50% bread wastes 3) 100%
spaghetti wastes 4) 50% spaghetti wastes 5) 100% equal mix of bread wastes and spaghetti wastes
and 6) 50% equal mix of bread wastes and spaghetti wastes. Blank diet prepared as same as commercial common diet. 21 polyethylene net
cages (lxlxl m) used for fish holding in a cement pond (30x3x1.2 m) with 10 lis water flow. Each
cage stoked by 20 fish with initial average weight of 85:f:5 g. Farming period was 75 days and in this period water temperature, pH and
dissolved oxygen were 14.5:f:2°c, 7.5-8.8 and 6.8-8.5 mg/l, respectively. The best growth
performance belonged to diet 4, although results diets of 2, 4, 6, and blank
no different (p〈0.05). In term of economic value of used diets, diets 2 had the best result. Carcass
analysis in the end of experiment showed that carcass protein and
ash contents in all of treatment were same but lipid content in treatments of 1, 3, and 5 were
lower than other treatments (p〈0.05).
