If aquaculture continues its rapid growth, up to 46% of wild-caught fish harvested globally could be used as feed for farmed fish and shrimp by 2040, according to a recent report from a UK NGO and University of British Columbia researchers. This projection underscores the evolving dynamics in global seafood supply and the push for sustainable practices.
- Aquaculture is set to expand up to 75% by 2040, impacting fish feed demand.
- Use of wild fish for feed currently stands at 13.3%; could rise to 46%.
- Sustainable farming choices strongly influence environmental impact.
What happened
A report published in early September highlights that if the aquaculture industry grows significantly as outlined by a U.N. roadmap, nearly half of the wild-caught fish harvested worldwide could be used to feed farmed fish and shrimp by 2040. This projection varies depending on the species farmed, with carnivorous fish and shrimp requiring more wild fish-based feed than others like shellfish or carp.
The report, created by the Changing Markets Foundation in collaboration with researchers from the University of British Columbia, coincided with the U.N. Committee on Fisheries meeting in Rome, where global fisheries policies are shaped. While aquaculture is responsible for half of all seafood today and continues to grow rapidly, representatives of small-scale fishers have voiced concerns over the industry's environmental and social impact.
Why it feels good
Aquaculture, being the fastest growing food sector globally, offers promising opportunities to help meet rising seafood demand and contribute to food security without further depleting wild fish populations. When farmed responsibly, aquaculture can provide a steady supply of nutritious protein to millions.
Importantly, the report clarifies that the environmental footprint depends heavily on the species chosen for farming. Species like shellfish and carp require little to no wild fish for feed, presenting a more sustainable growth model. This encourages thoughtful development aligned with sustainability guidelines, supporting both climate goals and global hunger reduction.
What to enjoy or watch next
Future trends in aquaculture species selection and feed innovation will be key to balancing industry growth with ecosystem health. Continued efforts to promote sustainable aquaculture practices and develop alternative feeds could reduce reliance on wild fish stocks, a critical factor for environmental stability.
Observers and consumers should watch for new policies from organizations like the FAO that aim to guide sustainable aquaculture growth. Advances in the farming of species requiring minimal fish-based feed, combined with better aquaculture management, could help the seafood sector thrive while lessening pressures on ocean resources.
