The timeline for scaled up usage of alternative salmon feeds based around insects, single cell proteins and algae remains unclear because of the relative cost of other ingredients, according to Ricardo Garcia, CEO of Chilean fishing company Camanchaca and main shareholder and chairman of salmon producer Salmones Camanchaca.

"It's a matter of price at the end of the day," Garcia said during IntraFish's Leadership Breakfast event at the Boston Seafood show, being held for the first time in three years because of the global COVID-19 pandemic.
