Abstract

Fish breeding and genetic improvement play crucial roles in enhancing aquaculture productivity, sustainability, and profitability. Biotechnological advancements have revolutionized these processes, offering innovative tools and techniques to accelerate genetic progress and address challenges in fish farming. This paper provides an overview of recent biotechnological advances in fish breeding and genetic improvement, including selective breeding, molecular genetics, genome editing, and reproductive biotechnologies. The application of these technologies in improving growth performance, disease resistance, and other economically important traits in farmed fish species is discussed, along with considerations for ethical, regulatory, and environmental implications.
