| Abstract | ||
| Newly hatched larvae of Carassius auratus and Cyprinus carpio var. koi were stocked separately in 50-liters culture tanks with 250 individuals/ tank in triplicate. Specimens were divided into four groups and fed with pelletized feed, Thermocyclops decipiens, Moina micrura, and mixed diet (50% T. decipiens and 50% M. micrura) for 40 days. The final results of C. auratus (length 21.40 ± 0.15mm and weight 54.79 ± 1.37mg) and C. carpio var. koi (length 25.73 ± 0.66mm and weight 65.07 ± 1.40mg) growth parameters, specific growth rate, biomass and percentage weight gain were significantly higher in T. decipiens feeding regime. However, the survival rates of both fish larvae were high in mixed diet regime. The biochemical profiles of both larvae were significantly different (P<0.05) between the feeding regimes. Based on the results, live-feed organisms are more effective foods than pelletized feed for the early stages of both larvae. | ||
