This investigation was aimed to study the effect of different levels of apple cider vinegar (0 (control), 1% (T1) 2% (T2) and 4% (T3) in diet) on growth and digestive enzyme activities of Carassius auratus. The study was lasted for 105 days and was conducted in completely random designe in triplicte. T3 showed a significant increase in final weight, weight gain, daily growth and specific growth rate Compared to the control. The highest condition factor was observed in T2 which was significantly higher than control. Based on results significant increments in protease and lipase activities were observed in T2 compare to the control, while amylase activity showed significant decrease in apple cider vinegar receiving treatments. Considering the antibacterial properties, the presence of beneficial nutrients along with the adjustment of pH of the digestive tract can increase growth; therefore, it seems that the use of apple vinegar in diet can be useful in increasing the production of some aquatic animals.
