Impact of Withania somnifera Supplementation on Growth, Reproduction and Hormonal Profile of Lepidocephalichthys thermalis in Captivity

Abstract: Background: Withania somnifera (Ashwagandha) is a widely known medicinal herb with numerous bioactive compounds that enhance growth, immunity and reproductive performance. This study evaluates the effects of W. somnifera ethanolic extract (WSEE) on growth, gonadal maturation, steroid hormone profiling in Lepidocephalichthys thermalis under controlled conditions. Methods: Fish were fed diets supplemented with WSEE at different concentrations (0, 100, 200 and 300 mg/kg) for 70 days. Growth performance, gonadosomatic index (GSI), serum steroid hormone levels and gonadal histology were assessed. Result: Results demonstrated significant improvements in growth parameters, with the highest weight gain (1.51±0.22 g) and specific growth rate (2.26±0.22) observed in the 300 mg/kg WSEE group. Additionally, FCR improved across treatments, with the lowest value recorded in the 300 mg/kg group (1.08±0.05), indicating enhanced feed utilization efficiency. Steroid hormone analysis revealed a dose-dependent increase in progesterone, estrogen and testosterone levels, with T2 (200 mg/kg) exhibiting the highest concentrations. Histological examination showed enhanced gonadal development, with increased vitellogenic follicles and reduced atretic structures in treated groups. These findings support the use of W. somnifera as a sustainable alternative to synthetic hormones in aquaculture reproduction management.
