As you probably have heard a million times – fish stocks are declining, but the demand for fish is increasing. But what you might not have heard is that every year, 30 million tons of fish are discarded.

Sterilising farmed fish offers the aquaculture industry a number of benefits. For farmers themselves, it can prevent fish from becoming sexually mature – desirable since maturation reduces flesh quality and makes fish more susceptible to diseases. Sterilisation can also restrict their environmental impact in preventing farmed genes, which are often suboptimal for a life in the wild, from being introduced into wild populations by escapees.
