Chinese scientists have unveiled new research showing that gene-editing technology could transform commercial fish farming by accelerating the development of faster-growing, disease-resistant fish while also advancing pharmaceutical research.
The study, conducted by researchers from the Chinese Academy of Fishery Sciences, Xinjiang Agricultural University and Yazhoubay Agriculture and Aquaculture Development, examines how modern gene-editing techniques can replace traditional selective breeding methods, which often take years to produce improved fish varieties.
Published in the journal Animals, the review highlights the use of advanced molecular tools such as CRISPR, base editing and prime editing to make precise genetic modifications that improve traits including growth, disease resistance and tolerance to environmental stress.
According to the researchers, fish are particularly well suited for gene-editing research because they produce large numbers of offspring and have relatively short reproductive cycles. These characteristics enable scientists to rapidly test genetic changes across multiple generations, significantly reducing breeding timelines.
The review also traces the evolution of gene-editing technologies, from early systems such as zinc-finger nucleases and transcription activator-like effector nucleases (TALENs) to today’s RNA-guided CRISPR platforms, which offer greater precision and allow multiple genes to be edited simultaneously.
Beyond aquaculture, the scientists say gene-edited fish could play an important role in medical research. Because fish share many genes with mammals, they can be engineered to mimic human diseases, providing valuable models for drug discovery, disease research and the testing of new therapies.

The researchers identified four major applications of fish gene editing: understanding gene functions, improving commercial aquaculture breeding, enhancing ornamental fish traits and creating disease models for biomedical research.
Despite the technology’s promise, the team stressed the need for strict biosafety standards and regulatory oversight before genetically edited fish are introduced into commercial production or natural environments.
They concluded that balancing innovation with environmental protection will be essential to ensuring gene editing contributes to sustainable aquaculture, global food security and biodiversity conservation.

The researchers also predicted that genetically improved fish varieties could become increasingly common worldwide, providing consumers with more sustainable, high-quality sources of protein in the years ahead.
