Determination of dietary protein and energy level s and optimum lipid to carbohydrate ratio for Gattan (barbus xanthopterus) fingerlings

This study was done is three phase ,to required suitable level of protein and energy and optimum carbohydrate to lipid ratio (B.xanthopterus) fingerling . Phase one: Determine of dietary protein and energy l eve in tanks (300 liters) treatment with triplicate e in different level of protein (25 ,30 ,35 percentage) and three level of energy (250 ,300 ,350 kcal/gr) the result showed that the best (GSR and WG) belongs to diet with protein % 35 and 300 kcal/gr. this experiment showed with increased of protein , SGR and WG increased and the one special level of protein with increased of energy level ,first SGR and WG increased (the most of SGR belonged 300 kcal/gr) ,and SGR decreased. Phase 2 : Determine optimum lipid to carbohydrate ratio in tanks (300 liters) In this phase with suitable level of protein and energy( protein %35 and 300kcal/gr) determined 5 ratio of carbohydrate and lipid (0.8, 2.8, 4.86, 8.8 ) in this phase best diet determined with 4/8 ratio , and 6/8 , 2/8 ratios were after that carbohydrate and lipid ratio. Phase 3: Determine optimum lipid to carbohydrate ratio in pond: In this phase, the result of thirty phase were like second phase. we determined that the best SGR and WG and WG % belonged to 4/8 carbohydrate and lipid ratio and 6/8 2/8 ratio were after 4/8 carbohydrate and lipid rate.
