Enrichment Low Protein Diets With Omega-3 (PUFA) and it's Effects on Growth Indices, Apparent Digestible Coefficient and Some Physiological Characteristics of Young Common Carp Cyprinus carpoi L.

Abstract

This study was carried out in the laboratories of fish and animal resource center for 90 days in 12 glass aquarium (40cm×30cm×70cm/70 L) to study the possibility of shoring or enrichment low protein diets with omega-3 (PUFA) and its effects on growth indices and some physiological characters of common carp Cyprinus carpoi L., formulated four different treatments with contain of protein 14.71-14.95 and energy between 1464.18-1467.70 K cal. Add fish oil as source of omega-3 at levels 0 T1, 1.5% T2, 2% T3 and 2.5% T4. A 96 fish were used an average weight of 16.19g ±0.45. The fishes distributed on four treatmentshree replicateeight observation for each replicate. The statistical results showed that T3 (2% fish oil) was the best treatment and significant distinction (P<0.05) on treatments T1 and T2 for all parameters which were weigh gain (WG),relative growth rate (RGR), food conversion rate (FCR) andapparent digestible coefficient (ADC), and there were no significant different between T3 and T4 (2.5% fish oil). The statistical results showed that when add fish oil there were improvement in red and white blood cell (RBC and WBC), Packed Cell Volume (PCV) and Hemoglobin Concentration (Hb).
