# Farmed salmon and tilapia are much more sustainable than previously thought - 地中海亞洲海洋聯盟

> A Utrecht University master's student has proposed a new method, eFIFO, for calculating fish-in-fish-out ratios. The method counts by-products as free raw material and suggests farmed salmon and tilapia need only about 1 kg of wild fish input for 3 to 4 kg of farmed output. The result challenges earlier estimates of feed inefficiency.

## Why it matters

If accepted, more favourable FIFO figures could ease pressure on the fishmeal and fish oil supply used by aquaculture, though the effect is a matter of research framing rather than immediate price movement.
