Advances in biotechnology and breeding innovations in China's marine aquaculture.

Biotechnology is the key driving force behind the sustainable development of aquaculture, as biological innovation would significantly improve the capabilities of aquatic breeding and achieve independent and controllable seeding sources to ensure food safety. In this article, we have analyzed the current status and existing problems of marine aquaculture in China. Based on these data, we have summarized the recent (especially the last 10 years) biotechnological innovation and breeding progress of marine aquaculture in China, including whole genome sequencing, sex-related marker screening, genomic selection, and genome editing, as well as progress of improved marine fish varieties in China. Finally, the perspectives in this field have been discussed, and three future countermeasures have been proposed.
