The Infrastructure Is Ready. Is the Animal?

The FAO’s State of World Fisheries and Aquaculture report (SOFIA 2026) came out this month, and the headline is genuinely historic: global aquaculture production crossed 100 million tonnes for the first time, reaching 103 million tonnes in 2024, worth $371 billion. Aquaculture now accounts for more than half of all aquatic animal production and feeds over three billion people.

The number that matters more to us got less attention. Wild fisheries have stayed flat, between 86 and 94 million tonnes, since the late 1980s. Every additional tonne of seafood the world has eaten since then has come from aquaculture. The industry has absorbed the entire growth in global seafood supply for more than three decades.

More production means more animals in more intensive systems: higher stocking densities, more frequent handling, more transfers per cycle. The SOFIA report is direct about this, climate change and environmental pressure are already affecting performance, and under high-emissions scenarios, exploitable fish biomass could decline more than 10 percent by 2050 in several regions. Infrastructure is scaling. The biological load on each animal is scaling with it. Animal resilience isn’t scaling with either one.

We think that gap gets addressed at the gut, not just at the cage or the water system. Cortisol rises, the gut barrier loosens, feeding stops, microbial communities shift, and none of that resolves the moment a stressor passes. Recovery takes time, and during that window, growth slows, feed efficiency drops, and mortality risk rises. At 100 million tonnes of production, that cumulative cost adds up fast.

This is the case for functional nutrition doing a job that standard feed formulations were never designed for. Protein, energy, vitamins, and minerals keep an animal alive and growing under normal conditions. Supporting barrier function, mucosal immunity, and microbial stability during a predictable stress window, like a transfer or a vaccination, is a different job entirely. It’s the one JUV is built for.
