Fishmeal

Fishmeal is a protein-rich powder rendered from whole forage fish (anchoveta, menhaden, sand eel) and from fish trimmings, used mainly in aquafeed and animal feed. Roughly a quarter of the global wild catch by volume goes to reduction into fishmeal and fish oil, so its demand links farmed seafood directly to the health of forage fisheries. Substitution with plant proteins, single-cell ingredients, and insect meal aims to break that link and lower the fish-in-fish-out ratio.
