Gene editing in aquaculture
The document is a brief of a specific aquaculture innovation. It contains information on the technique and approach used, scope and scale of application, accessibility and the outcome and benefits of the innovation.
Gene editing holds significant potential to enhance selective breeding. While selective breeding has been successful, it is limited by the heritability of the trait. Gene editing also prevents interbreeding with wild fish should they escape from a farm and offers the potential for improved growth rates. Current studies into gene-editing cover a wide range of aquatic species – including various salmonids, rohu, grass carp, common carp, channel catfish, Pacific cupped oyster, Nile tilapia and red seabream. However, the regulatory hurdles and the issues of cost and ethical concerns remain the constraints for upscaling.
