A new report suggests that almost half of the world's wild-caught fish could be used to feed farmed aquaculture products by 2040.

The rapid expansion of the aquaculture industry, as outlined in a roadmap developed by the U.N. Food and Agriculture Organization (FAO), is expected to drive this shift. This trend could significantly alter marine ecosystems and fishing economies, leading to potential overfishing and depletion of wild fish stocks.

This means that more wild fish will be diverted from human consumption to feed farmed species like salmon and shrimp, potentially affecting food security in regions dependent on these resources.

The long-term vulnerability includes the risk of depleting key marine species, which could disrupt entire ecosystems and affect the livelihoods of communities relying on fishing.

What is the long-term climate outlook for this region?

This shift in fish usage highlights growing pressures on marine resources due to aquaculture expansion. It raises concerns about sustainability and food security, especially in coastal regions where fishing is a primary economic activity.

The outlook remains uncertain but leans towards increased ecological strain.
