# UC Santa Cruz Scientists Create Fish Feed Without Fish

> UC Santa Cruz researchers developed a fish-free feed in which young rainbow trout grew as well as on a standard fishmeal and fish oil diet over 12 weeks. The study was published in October 2026 in Antioxidants. Fish farming is cited as using about 87% of world fishmeal and 74% of fish oil, and fishmeal output has fallen sharply.

## Why it matters

Fish-free feed could eventually reduce long-run demand for fishmeal and fish oil from trout and salmon farms. Current tight fishmeal supply keeps prices firm in the near term.
