| Özet |
| In this study, ginseng root extract was manufactured and used as a food additive for 8 to 9-month old male rainbow trout (Oncorhynchus mykiss). The extracts were added to the food in two different ratios, 1 g/kg and 2 g/kg. The control group was given a commercial feed with no additive. The fish ate the provided feed for 120 days ad libitum. Sperm samples were taken from fish every 30 days. We observed that the gonadosomatic index (GSI) in the experimental groups was higher than in the control group. Motility duration of groups 1 and 2 was 10 seconds more than the control group. Sperm density averages (SDA) were 7.74±0.61x109, 8.62±0.53 x109 and 11.27±0.78x109, respectively. All sperm samples taken from each experimental group were used for fertilization. Fertilization ratios of control and experimental groups were 65±10%, 84.9±5% and 90±6%, respectively. The hatching ratio was also very high in the extract added groups compared to the control group. |
