One thousand and eighty rohu fingerlings with an average size of 8.5 ± 0.5 g were randomly distributed in 6 distinct experimental groups in triplicates, where the first three groups were exposed to high stocking density (HSD; 20 nos/ 75 L water) with restricted feeding (RF), viz. THR0 (HSD, RF, 0% nutraceutical), THR1 (HSD, RF, 0.1% nutraceutical) and THR5 (HSD, RF, 0.5% nutraceutical), and second three groups were exposed to normal stocking density (NSD; 10 nos /75 L water) with satiation feeding (SF) and designated as TNS0 (NSD, SF, 0% nutraceutical), TNS1 (NSD, SF, 0.1% nutraceutical) and TNS5 (NSD, SF, 0.5% nutraceutical). The weight gain (WG) %, specific growth rate (SGR), protein efficiency ratio (PER) and IGF-1 expression were significantly lower, whereas feed conversion ratio (FCR), serum superoxide dismutase (SOD) and catalase activities were significantly higher in fish exposed to HSD with RF at monthly sampling. Feeding of 0.1% dietary nutraceutical resulted in a significantly higher WG%, SGR, PER and IGF-1 expression and lower FCR, SOD and catalase activ-ities at the end of the third and fourth month of feeding in HSD with RF groups. The present study concluded that 3-month feeding of 0.1% nutraceutical could improve growth and reduce stress in fish.
