The potential of fish and shellfish production to feed a growing global population could be significantly enhanced through advances in genetics and biotechnology, researchers have said.....MUCH MORE
Many species of fish and shellfish have been domesticated relatively recently compared with most livestock species, and so have diverse gene pools with major potential for selective breeding, according to the review paper in Nature Reviews Genetics.
The development of tools to gain insight into the genetics of these species, and apply such tools for breeding and management, provides opportunities to release that potential, researchers say.
Most aquaculture species can produce many offspring, and large populations with improved genetics can be bred quickly for improved production performance.
The benefits may include improved growth, resistance to disease or robustness in diverse farming environments.
Farmed fish is on course to overcome wild fish as the main source of seafood, and consequently genetic tools and expertise are in high demand to increase the efficiency and sustainability of aquaculture systems, which currently rely mostly on unselected stocks....
