Such platforms help formulate adaptive breeding strategies by tracking global breeding progress in real time. With the expansion of the industrial scale, a sound data collaboration system will become the cornerstone for maintaining the sustainability of genetic gain (Ruan, 2016; Yanez et al., 2020). 8 Concluding Remarks Systematic analysis confirmed that the growth traits such as body size and muscle production of Nile tilapia have moderate to high genetic improvement potential, and significant genetic gain can be achieved through targeted breeding strategies. Typical examples show that six consecutive generations of selection and breeding have cumulatively increased the increment and growth rate of muscle tissue by the order of 1.87 standard deviations, and the single-generation genetic gain has been stably maintained within the range of 10%~15%. This improvement process was achieved on the premise of maintaining a stable survival rate, confirming the biological feasibility of the genetic improvement strategy. Modern technologies such as molecular marker-assisted breeding and genomic prediction systems are driving industrial upgrading by enhancing the efficiency of genetic assessment. Compared with traditional family analysis methods, genomic selection technology has increased the accuracy of breeding value prediction by 37%, while the precise localization of growth-related gene clusters provides molecular targets for trait improvement. The breakthroughs in the research and development of gene function analysis technology and SNP high-throughput screening platform have laid a technical foundation for building excellent strains with high growth performance and low feed consumption. Maximizing genetic potential requires the establishment of an international collaborative mechanism and an open data platform. International genetic improvement programs (such as the GIFT project) have verified the feasibility of cross-border integration of genetic resources and joint breeding models. Building a multi-dimensional database integrating genotypes, phenotypes and environmental factors can accelerate the transformation of technological achievements, achieve cross-regional genetic data linkage analysis, and promote the development of low-carbon tilapia farming models.
