Are the animal by-products used in aquaculture feeds dangerous to human health?
No. The safety of animal by-products has been proven by numerous scientific studies. Utilising these raw materials that would otherwise go to waste also helps to dramatically reduce the amount of fish meal and fish oil used by the industry. This contributes to the sustainability of the food industry and the circular bioeconomy.
Various by-products from the slaughter and processing of animals destined for human consumption are used in aquaculture feeds. These raw materials are completely safe because they come from sources that have previously been subject to veterinary checks and have been determined to pose no danger to human health. These by-products are high in important protein, fat and minerals, and are therefore of precious nutritional value to carnivorous aquaculture species.
The use of these raw materials in aquaculture delivers considerable benefits from an environmental perspective as it allows us to use resources that would otherwise go to waste to produce more food.
Frequent questions on feed ingredients
What ingredients are in Skretting feed?
Aquaculture feeds contain essential nutrients that should be delivered in the right quantities to keep fish and shrimp growing well and healthily. These nutrients come from a variety of different sources. In addition to fish meal and fish oil, they often contain other vegetable-based meals and oils, fish trimmings and processed by-products from land animals.
Are the raw materials that Skretting uses in its feeds responsibly sourced?
Yes. At Skretting, we maintain that one of the most positive sustainability impacts that we can have is to ensure that we manufacture our feeds from responsibly sourced raw materials.
Are the animal by-products used in aquaculture feeds dangerous to human health?
No. The safety of animal by-products has been proven by numerous scientific studies. Utilising these raw materials that would otherwise go to waste also helps to dramatically reduce the amount of fish meal and fish oil used by the industry.
Do salmon and trout feeds contain colouring?
In the wild, the flesh of salmon and trout can be a red/pink colour, due to an antioxidant called astaxanthin. Astaxanthin is produced in natural waterways by algae, yeast and bacteria, all of which are in the food chain of salmonids. Astaxanthin is an essential nutrient for salmon. It is required to remain healthy and disease free.
Do feeds contain growth hormones or antibiotics?
No. Skretting feeds do not contain any growth-promoting hormones. In some markets, antibiotics are added to Skretting feed upon customer request and per veterinary prescription, in accordance with specific rules established by law.
Do feeds contain chemicals or preservatives dangerous to human health?
No. Aquaculture feeds are subject to strict checks to ensure that they do not pose any threat to human health. Any preservatives used must comply with laws and regulations governing their use.
What is ethoxyquin and is it safe?
Ethoxyquin is an antioxidant that protects and maintains the quality of the omega-3 fatty acids in fish meal, particularly during transport and storage.
What are fish meal and fish oil, and why are they used in aquaculture feeds?
Fish meal is a powder obtained after cooking, pressing, drying and milling fresh raw fish, while fish oil is a liquid pressed from the cooked fish. Both are produced from harvesting short-lived, fast-growing stocks of small, bony and oily fish for which there is little or no demand for human consumption.
How much wild fish is needed to feed farmed fish?
Skretting now has the knowledge and R&D to produce Atlantic salmon feeds requiring zero fish meal, and zero fish oil. We invest in R&D that provides full flexibility.
Does Skretting use novel ingredients in its feeds?
Yes. Skretting is in full support of the development of novel ingredients and we have been using some of these in our diets with the support of those customers.
