Alaska explores onshore salmon farming to protect wild stocks

Alaska's fisheries landscape is poised for transformation as advancements in fish farming technology gain traction. During a recent meeting of the Alaska State Legislature's Fisheries Committee, legislators discussed the evolution of fish farming practices, particularly the shift from traditional offshore net pens to innovative onshore facilities.

Historically, concerns about the impact of farmed fish on wild salmon stocks led to a preemptive ban on commercial salmon farming in Alaska. However, with the emergence of new technologies that isolate farmed fish from wild populations, the conversation is shifting. Onshore farming methods, which have been successfully implemented in countries like Norway, are now being explored in the U.S. and could offer a sustainable solution to meet the growing global demand for seafood.

Key advancements highlighted include recirculating tanks that minimize water usage and enhance fish growth conditions, as well as digital twin technology that allows for real-time monitoring of farming operations. These innovations not only improve efficiency but also promote humane practices in aquaculture.

The committee also discussed the potential for aquaponics in Alaska, which combines fish farming with plant cultivation. A recent visit to an indoor Arctic char farm in Whitehorse showcased the viability of such systems, where the farm successfully produces sterile fish and sells them to markets in Canada.

As Alaska considers the future of its fisheries, these developments could pave the way for a new era of sustainable fish farming, balancing economic opportunities with environmental stewardship. The implications of these discussions are significant, as they may reshape the state's approach to aquaculture and its relationship with wild fish populations.
