Determination of nutritional requirements of kutum fish (Rutilus frissi kutum) fingerling

Three experiments carried out to determine optimize level of crude protein, lipid and gross energy requirements of Kutum fish (Rutilus frissi kutum) fingerling. A completly randomized design consisted of 4 treatments with triplicates which those was used with four experimental dietary crude protein levels (35, 40. 45 and 50% CP), Four crude lipid levels (8, 12, 16 and 20%) and four gross energy levels (4250, 4500, 4750 and 5000 k cal/kg of diet) being tested separately. Kutum fish fingerling averaging 1067 ± 98 mg,,2378 ± 185 mg, and 1067 ± 143 mg respectively and stocked with density of 20 fish at volum 80 liters. Fish fed with 3% of wet body weight at three times, 9 am, 12 am and 4 pm. The following performance parameters were evaluated final weight, weight gain, feed intake, feed conversion ratio, specific growth rate, protein effieciency ratio and condition factor. Fish fed diets 40% CP, 20% CL and 4500 K Cal/kg Gross energy could meet the nutritional requierments of kutum fish fingerling.
