When the research developed the AquAdvantage salmon, it dawned on everyone quite quickly that escape was going to be a major concern. That's why the company invested in the technologies of using only female sterile fish in a land-based facility, because the whole idea of land-based is that now you've isolated and contained your fish, so they're not going anywhere. In fact, AquaBounty has been asked to speak at conferences on biosecurity because we are an acknowledged leader in this area.
