Abstract :
In this research, the effects of using powder and liquid of Sanyar prebiotic on the water nitrogen compounds and the physiological performance of Common carp in biofloc system were investigated. Common carp (10.09 ± 0.45 g) were stocked into 18 tanks (35 L) in six treatments for 60 days, including: Control treatment without additive with clean water (C), Control treatments without additive with Floc (FC), Floc treatments with 0.1 and 0.2 g (FP1 and FP2) powder prebiotic and Floc treatments with 1 and 2 ml (FL1 and FL2) liquid prebiotic per 100 g of basic diet. Water parameters are maintained at the standard level for this species. Total ammonia concentration (TAN) was statistically significant between experimental treatments. The growth of fish was obtained significantly higher and the feed conversion ratio was lower in FP1. The highest intestinal protease activity (8.42± 0.05) was obtained in FP1 treatment. The immunoglobulin and lysozyme serum in FP2 and FL1 were significantly higher than in the other treatments. The results of this study show that the use of 0.1 g of Sanyar prebiotic powder per 100 g of basic diet in the biofloc system could improve growth performance, and the immune status of C. carpio.
