Large salmon farming companies across Europe are introducing feed made from poultry by-products, such as bones and organs, for their fish. This change is a response to the escalating cost of traditional fishmeal, which has doubled in price over the last two years. Poultry-based feed, by contrast, costs approximately half as much per tonne.
Disagreement on consumer awareness
While some reports indicate consumers may not be aware of the change because feed ingredients are not listed on product labels, others suggest that supermarkets were previously reluctant to sell salmon raised this way due to fears of consumer backlash. The Daily Mail notes that market research suggests people are not aware of the ingredients in animal feed.

How each side covered it
Our own reading of the reporting listed below, written from the outlets’ articles rather than quoted from them. The reasoning is set out on our methodology page.
Left
3 rated outlets
- Reports from the left-rated outlets focused on the shift to poultry by-products for salmon feed. Channel 4 News highlighted that some of Europe's biggest fish farmers are now using these materials. IFLScience noted consumer apprehension, stating people are 'fishy' about feeding chicken to salmon. Spiegel reported that feeding farmed fish animal protein was forbidden until 2013 and that the taboo appears to have fallen, suggesting manufacturers had previously avoided it due to consumer fears.

- The centre-rated report from the Daily Mail detailed the introduction of poultry bone and organ feed at offshore farms by Leroy Seafood Group, a supplier to Tesco. It also stated that Mowi, a supplier to Sainsbury's and Asda, plans to use poultry feed in Scotland and Norway. The report explained that traditional fishmeal prices have doubled while chicken-based feed is half the price. It also noted that feeding salmon animal protein was illegal until 2013, with restrictions later relaxed due to new evidence showing no risk of BSE transmission. The article included expert opinion stating the feed is safe and high-quality, and mentioned that salmon farmers in Chile and Canada have used these methods for years. A key concern raised was the lack of transparency, as feed ingredients are not required to be listed on product labels.
Right
3 rated outlets
- Right-rated reports from Svenska Dagbladet and Kronen Zeitung highlighted that chicken is now on the salmon menu and that salmon being bred is getting more chicken to eat. These reports noted that this practice was previously seen as unnatural by consumers and that Norwegian salmon producers are now choosing to break an unwritten law. Vz.ru stated that the largest European salmon producers have begun using chicken meat as feed due to a sharp increase in fish flour prices, with poultry-based feed costing more than half the price per ton of fishmeal. The reports mentioned that the price of fish flour has nearly doubled over the past two years.
Questions about this coverage
- How did the left and right cover Salmon farms switch to chicken feed amid rising costs?
- Of the 7 outlets on this story carrying a published leaning rating, 43% are rated left, 14% are rated centre, 43% are rated right. Those percentages are shares of the rated outlets, not of every outlet that ran it, which was 20. The sections above set out what each side emphasised, in its own terms.
- Is Salmon farms switch to chicken feed amid rising costs left or right?
- Too few of the outlets on this story carry a published leaning rating to say. 7 of them do, and this site does not characterise a field under 12: at that size one newsroom filing moves the share by ten points. The percentages above are the count as it stands.
- Is the coverage of Salmon farms switch to chicken feed amid rising costs biased?
- Salmon farms switch to chicken feed amid rising costs is one event reported by 20 outlets, and this page does not rate the story as biased or unbiased. What it publishes is the spread: which outlets ran it, where named rating organisations place each of them on the spectrum, and what each side chose to lead with. A leaning rating describes an outlet's record over time, not this article, and the two should not be run together.
- Which outlets covered Salmon farms switch to chicken feed amid rising costs?
- 20 that we know of, every one of them listed further up this page with a link to its own report and to what we hold on the publisher. Nothing here is a summary of somebody else's summary: the outlets are named so the original reporting can be read.
- Why are salmon farms switching to chicken feed?
- Salmon farms are switching to chicken feed because the price of traditional fishmeal has doubled over the past two years. Poultry-based feed costs about half as much per tonne, offering significant cost savings for producers.
- Is it safe to eat salmon fed on chicken by-products?
- Yes, experts state it is safe to feed salmon on chicken by-products. These products are high-quality proteins similar to fish meal and do not carry risks such as bovine spongiform encephalopathy (BSE) prions.
- When did feeding salmon animal protein become legal?
- Feeding farmed salmon with animal protein was illegal until 2013. After that date, restrictions were relaxed, allowing producers to use ingredients like poultry by-products.
- Will consumers know if their salmon is fed chicken?
- It is unclear if consumers will know. Manufacturers are not required to list the ingredients used in animal feed on product labels, meaning consumers may not be aware of the change from fishmeal to chicken-based feed.
