Genetics and RAS: does the new frontier in global aquaculture require a fresh approach to selective breeding?

One of my first experiences of working in the aquaculture industry was on a tilapia farm in Cambridgeshire, thousands of miles from anywhere a tilapia would normally call home. Those were the early days of recirculating aquaculture systems (RAS) – it was the beginning of a new frontier that was technically and economically risky. Many tried and many failed.
