Wisconsin land-based fish farmer and hydroponic vegetable grower has begun selling its first Atlantic salmon in Festival Foods stores in the northern US state.
The firm, Superior Fresh, has an annual output of around 72 tonnes of Atlantic salmon and steelhead trout combined, three-quarters of which is salmon, The Fish Farming Expert reported.
The company harvested 900kg HOG (head-on-gutted) Atlantic salmon during the last week of June. The salmon weigh around 4-4.5kg as HOG fish, and sell at a premium price.
The company’s president, Brandon Gottsacker, told Aquaculture North America that concept to harvest took approximately three and a half years.
“Facility design began in early 2015 and construction commenced in early 2016. There were a lot of lessons learned along the way. The largest lesson is truly understanding the relationship between the Fish House and the Greenhouse and optimising both simultaneously,” Gottsacker pointed out.
He added that there are no other facilities that are currently growing Atlantic salmon in the United States let alone in conjunction with a commercial greenhouse.
“We plan to harvest Atlantic salmon and steelhead every week of the year in order to make sure that the freshest product is available to the consumer,” the firm’s president stated.
Superior Fresh uses a recirculating aquaculture system (RAS) which re-uses 99.9 per cent of its water because leafy greens grown in a three-acre hydroponic greenhouse take up excess nutrients.
RAS expert Steve Summerfelt, a long-time advocate of on-land salmon farming, recently joined Superior Fresh to manage the company’s scientific research and technological, promoting efficiency and profitability at the company’s current and future facilities.
“Salmon production is ramping up as we now harvest weekly to offer local, fresh, healthy, and tasty fillets to Midwest seafood consumers. These fish are also considered “Best Choice” by the Monterey Bay Seafood Watch Program.
