Letter: Why insects may not make good food for farmed fish

Published 4 December 2024

From Dustin Crummett, The Insect Institute

On the idea that insects hold the answer to the dilemma of how best to feed farmed fish, peer-reviewed research I recently coauthored, along with industry statements, casts doubt on the ability of insects to compete economically with fishmeal made from wild-caught fish (Letters, 16 November).

If insects don’t compete with fishmeal, obviously they won’t solve the serious environmental challenges posed. Even if they did, they score worse than the status quo on some environmental metrics, such as greenhouse gas emissions.
