Abstract
Grass carp is one of the valuable fishes in the poly culture system that, it mostly use from aquatic plants in pond. In order to investigate the impact of different vegetative nutrients and pellet on the growth indices of Ctenopharyngodon idella, an experiment (90 days) was conducted at the aquatic research center of Shahid Fazli Barabadi Fisheries Faculty in Gorgan University of Agricultural Sciences and Natural Resources. In this research, three types of vegetative nutrients: Alfalfa, Lemna sp and Azolla filiculoides have been used with the 20 percent body weight and two types of pellets food containing 25 and 35 percent of protein, with 5 percent of body weight whit three replicates per treatment for a total of fishes, and in each treatments had 15 small fishes with the average weight of 15.41± 0.51g have been applied. The experiment results after the research period indicated that the most rate of the growth performance is related to treatment fed alfalfa plant and it had significantly different to other treatments (P>0.05), followed by Lemna sp. and had significant difference from other treatments (P<0.05). The lowest growth performance observed in the pellets containing 25 percent protein that it had significantly different to other treatments (P>0.05). And also in growth parameters, A. filiculoides and formulated feed with 35% protein was not significantly different from each other (P<0.05) in growth performance. In blood factors, there was not observed any significantly different in mean corpuscular hemoglobin Corpuscular (MCHC) index (P<0.05) in treatments. Also the maximum of red blood corpuscular (RBC) was observed in Lemna sp., Azolla filiculoides, Alfalfa and pelleted diet with 35% protein, than they had not significantly different to each other (P<0.05).
