Morphometric and reproductive-biological traits of grass carp (Ctenopharyngodon idella Valenciennes, 1844) aged 3-5 years (n=540; 270 females, 270 males) reared in 2023-2025 at three farms (one monoculture, two polyculture) were studied. No significant differences in body size were found among farms (p>0.05), whereas gonadosomatic index (GSI) differed significantly among all three farms (Welch ANOVA, F=838.15; p<0.001; Games-Howell post-hoc). Compliance with the GSI≥12% criterion showed an absolute association with farm (100%, 0% and 100%; χ²=226.0; p<0.001). Most importantly, females selected by the GSI criterion significantly outperformed a traditional unselected control group on every reproductive measure ‒ relative fecundity (141.4 vs 111.8 thousand eggs/kg; p=0.023), fertilization rate (86.6% vs 78.0%; p<0.001), hatching rate (80.5% vs 74.1%; p<0.001), and survival to active feeding (75.7% vs 65.0%; p<0.001). These findings experimentally validate the practical effectiveness of GSI-based selection as a scientifically grounded method for forming a high-productivity broodstock.
