The current investigation was conducted for a period of 90 days to examine the effect of two different doses of Ashwagandha (2% and 3%) on somatic and gonadal development in Cirrhinus mrigala. A total of 270 fish with mean length-weight of 27.49±3.36 cm and 235.5±60.29 gm were stocked randomly into nine earthen trial ponds and distributed as 30 fish in each pond. Whole experiment was of 3 different treatments, T1 (Control), T2 (2% Ashwagandha added diet) and T3 (3% Ashwagandha added diet) and each treatment was designed with 3 replications. During the experiment values of water quality parameters such as pH, Temperature, Dissolve Oxygen and TDS were found within optimal range. Gonadosomatic Index (GSI) for both male and female in April found maximum in T3 and their values were found 2.04±0.1 and 6.73±0.12 respectively (P<0.05). Values of biological indices of male C. mrigala such as regression coefficient “b” (2.44), condition factor (1.08) and SGR (1.08) was found maximum in T2 while in female C. mrigala, regression coefficient "b" (2.1) and SGR (0.256±0.004)was found maximum in treatment T3. In conclusion, 3% Ashwagandha added diet could be a option for obtaining appropriate somatic and gonadal growth of female while in male 2% Ashwagandha supplemented diet could be appropriate for somatic growth and 3% for gonadal growth.
