Journal letter: Better profit from tuna than salmon

A publication dealing with commercial salmon fisheries, Salmon Business, based in Norway, published a story in January 2022 indicating that a better profit can be made by raising yellowtail tuna rather than salmon in land-based recirculating aquaculture systems (RAS) originally designed for salmon.

The tuna grows to a much larger weight than salmon and is a fish used in sushi, bringing double the profit generated from raising salmon. Apparently, the existing land-based recirculating aquafarm tanks also can accommodate raising tuna (salmonbusiness.com/norways-first-land-based-salmon-facility-is-considering-ditching-salmon/).

Makes me wonder if there is more to Eric Heim’s decision to leave Nordic Aquafarms at this point in time.

Food for thought.
