This research was carried out to determine the effects of adding 0, 30, 60 and 120 mg/kg ginseng to the diets (T1, T2, T3 and T4) on growth performance and head development of goldfish. The trial was randomly divided into four groups, 30 goldfish in each group for 90 days. As a result of the research, it was determined that the addition of ginseng (60 and 120 mg/kg) to the diets (T3 and T4) significantly increased the specific growth rate, total live weight gains, head and body height of the fish compared with the fish fed with the control diet (T1) (P < 0.05) (P < 0.01). However, there was no positive effect on live weight gain, head height, and body height in fish fed the T2 diet. All ginseng feeds positively affected head widths, feed consumption, and feed efficiency of fish. On the other hand, in this study, the body lengths of the fish were not significantly affected by ginseng application. Especially because of the risk caused by the use of ginseng, it seems that 60 mg/kg ginseng can be used as an appropriate dose in goldfish.
