Feeds is major of current values in intensive fish and other aquatic animal culture (30-60% approximately). Therefore, aquaculture scientists have been attempted to find feed costs decreasing approaches. Earth worm (Eisenia fetida) is one of the most important commercial species. It can use in fish farming especially rainbow trout farms. Therefore, the study was conducted to investigate E.fetida effects on the growth and hematological indices in rainbow trout. For this purpose, juvenile fish with an average weight of 10 g were evaluated for 10 weeks. The experiment carried out with 4 treatments (each treatment includes 90 fish) . Fish were feeds by 0, 10, 20 and 30 percentages of feeds by earth worm. Results showed any differences between the groups.
