Unilateral eyestalk in S. hydrodroma has resulted in increased feed intake (0.72±0.04/ 0.62±0.84 and 0.39±0.07/ 0.29±0.1), daily growth rate (0.41±0.39/ 0.16±0.1 and 0.14±0.34/ 0.05±0.08), heart index (.37±0.66/ 3.14±0.1 and 3.04±0.35/ 2.95±0.43), testicular index (1.34±0.73/1.09±0.07) and ovarian index (0.33±0.1/0.15±0.03) in male and female ablated against their control and equated with the gonadal biochemical indices with higher protein (37.26±1.17/19.32±1.17 and 36.2±0.97/32.22±0.84), carbohydrate (322.19±1.23/92.89±0.93 and 159.19±1.00/91.09±1.12) and lipid (33.17±1.05/29.22±0.88 and 36.11±0.93/32.09±0.91) levels on UEA. A negative correlation with somatic biochemical indices with decreased levels of proteins (95.95±1.36/141.22±1.2 and 114.28±0.9/138.25±1.09), carbohydrates (4.67±0.77/5.58±1.17 and 3.56±0.8/4.43±1.2) and lipids (84.25±1.08/87.5±1.1 and 89.51±1.16/91.52±1.21) demonstrates the mobilization of such nutrients from somatic tissues to gonads for its growth and development with UEA.
