Tides Turn for Seafood More Fish are Farm-Raised than Caught in the Wild
For the first time in history, on June 7th, 2024, the United Nations reported that we now farm more seafood than we catch from the wild. At the same time, overfishing of wild fish stocks continues to increase even as the number of sustainably fished stocks declines.
This milestone was in many ways an expected one, given the world’s insatiable appetite for seafood. Consumption of seafood has grown at twice the annual rate of the global population since 1961.
Meeting this growing global demand for seafood was almost certainly going to necessitate an increase in aquaculture. As Dave Martin, program director for Sustainable Fisheries Partnerships, an international organization that works to reduce the environmental impact of seafood supply chains explains, “ Fishery production levels fluctuate from year to year, but it’s not like there are new fisheries out there waiting to be discovered, so any growth in consumption of seafood is going to come from aquaculture.”
Bryton Shang, CEO of San Francisco-based aquaculture tech startup Aquabyte, points out that, “The report highlights a huge potential for aquaculture to bring economic and food security to countries around the world.”
“There has absolutely been more action from regulators, nonprofits and businesses, and more conversations around the industry itself, that are evolving with new types of partnership developing,” Shang said.
As an example, the Walmart Foundation and Chilean salmon farmer Blumar Seafoods have partnered with The Nature Conservancy to experiment with co-farming seaweed as a way to improve fish-farm water quality. This uptick in crucial innovations and regulations has “accelerated the production of sustainably and ethically grown seafood,” Shang said.
While many problems have been linked to in-demand, intensively farmed species such as salmon and shrimp that rely on fish-based diets, farmed shellfish can, in contrast, actually improve the surrounding ecosystem, according to research published in Marine Policy. Farming herbivorous fish using indigenous Hawaiian techniques has also been reported to improve water quality and increase native fish populations.
“Producing food has impacts,” states Manuel Barange, director of the FAO (Food and Agriculture Organization of the United Nations Fisheries and Aquaculture Division). “Aquaculture allows us to control and analyze what impacts we are prepared to accept and which ones we do not.”
In May 2024, the FAO agreed to a set of sustainable aquaculture guidelines to help states navigate these trade-offs.
