Abstract

The present study was conducted to investigate the effect of replacing fish meal with corn gluten in the diet and its effect on the growth performance and biochemical composition of common carp fingerlings. For this purpose, 180 common carp fingerlings with an average weight of 5.04±0.5 grams and the average total length of 8±3 mm in 12 tubs with a density of 15 in each tub and in four different treatments of 20, 40 and 60% corn gluten along with a control treatment with a diet formulated with the percentage of protein, fat and The same energy levels were tested over an eight-week period. At the end of the test period, based on the obtained results, there was no significant difference between the growth indices in the investigated treatments and the control sample (P>0.05). Also, the analysis parameters of baby fish carcasses showed that there is no statistically significant difference between the treatments in terms of carcass moisture percentage (P>0.05), but in terms of ash percentage, protein percentage and carcass fat percentage, there is a statistically significant difference between all treatments. was observed (P<0.05). Therefore, it can be said that the use of corn gluten at the levels used in this research was favorable for fingerling carp.
