Genotyping is a critical process in aquaculture, enabling the identification of genetic markers associated with growth, disease resistance, and environmental tolerance in aquatic species. Through genotyping, researchers can select parent fish with optimal genetic profiles, ensuring that desired traits are passed on to the next generation. The technology supports improved breeding programs by providing insights into hereditary diseases and potential responses to environmental stressors. High-throughput genotyping techniques, such as next-generation sequencing (NGS), make it possible to analyze large populations efficiently. By integrating genotyping into aquaculture, producers can enhance stock quality, leading to healthier, more resilient, and productive fish populations suited to diverse aquaculture conditions.
