The infographic synthesizes the findings of the scientific review by Abdullahi et al. (2026) published in the journal Biology, highlighting how genetic improvement can mitigate commercial feed costs, which account for 50% to 70% of operating budgets on aquaculture farms. The visual resource systematically breaks down key zootechnical metrics—including Feed Conversion Ratio (FCR) and Residual Feed Intake (RFI)—while outlining the foundations of cumulative genetic heritability across generations. Furthermore, the graphic contrasts tangible progress achieved through conventional selective breeding—such as a reduction of up to 20% in rainbow trout FCR after ten generations or a 15.7% gain in GIANT tilapia—with the predictive precision of genomic selection supported by low-cost DNA panels. Finally, it outlines early proof-of-concept trials in CRISPR gene editing for species such as red sea bream and channel catfish, highlighting the imperative for commercial validation and international regulatory harmonization.
