Genetics expertise could transform fish production

The potential of fish and shellfish production to feed a growing global population could be significantly enhanced through advances in genetics and biotechnology. Most aquaculture species can produce many offspring, and large populations with improved genetics can be bred quickly for improved production performance. 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.

In the future, technologies such as genome editing could be used to introduce desirable traits, such as disease resistance, into farmed species, and surrogate breeding could be employed to support production of preferred species.
