Land-based farmed salmon producer AquaBounty on Tuesday announced a slight loss in its third-quarter earnings as the company moves closer to scaling production of it genetically engineered AquAdvantage salmon (AAS).

"In the second quarter we successfully started harvesting conventional salmon with the intention of refining the processes, operating procedures and partner relationships required for the first harvest of AAS," said Sylvia Wulf, CEO of AquaBounty.

"The foundational work with these first conventional harvests was crucial as it has allowed us to implement the necessary logistical and operational processes for a successful and de-risked first harvest of AAS, including refinements of quality and productivity operational parameters."
