Fishmeal and fish oil have traditionally been the main ingredients in feed for farmed salmon. Today, less is used of these ingredients. To find out how much fish oil and fishmeal goes into the production of farmed fish, Fish In Fish Out (FIFO) is calculated, which is the ratio between the amount of wild fish in the feed and the amount of farmed fish produced.

Fishmeal and fish oil have an optimal nutritional composition for farmed fish, and they were previously both affordable and readily available ingredients. Today, fishmeal and fish oil produced from wild fish are limited resources, and global growth in seafood production requires less use of wild fish as a raw material in fish feed.
