Frequently asked questions

Skretting's purpose is 'Feeding the Future', but what does that mean? Globally, there is increasing competition for land, water and energy – all of which will increasingly affect food production. Safe, high quality protein is essential, and aquaculture has the potential to provide this for a world population that is growing at an unprecedented rate. 

We get a lot of questions about aquaculture - what it is and what it means - and here we are trying to answer some of these, largely from a fish and shrimp feed producer standpoint, but sometimes on behalf of the industry, to provide a clear understanding of aquaculture and of the measures we are taking to fulfil our purpose. We’re committed to achieving this with a strong focus on reducing our environmental footprint and increasing our positive social impact.

what the Global Seafood Alliance says about the importance of aquaculture

Feed management

  • Sea bream juvenile

    Is one feed sufficient for all aquaculture species?

    No. Fish and shrimp have different nutritional requirements depending on their species, life stage, health status and production conditions. Feeds are formulated for defined nutritional needs and intended uses rather than as one solution for every species or stage of production.

  • Feed bags

    How much feed is needed to grow a farmed fish?

    The amount of feed needed depends on the species, life stage, feed, health, farming conditions and feeding management. Feed conversion ratio, or FCR, describes the amount of feed used to produce one kilogram of weight gain. A lower FCR means that less feed is required.

Animal health and welfare

    Why do aquaculture species grow quickly?

    Growth rates vary by species, genetics, life stage, feed, health, water quality, temperature and farm management. Some farmed fish and shrimp species grow relatively quickly because their biology is suited to the production environment and because producers manage nutrition and farming conditions for the species being raised.

  • Fish meal

    Is a low fishmeal and fish-oil content harmful to fish and shrimp?

    A lower fishmeal and fish-oil content is not inherently harmful. Fishmeal and fish oil provide valuable nutrients, but feeds can use a range of suitable ingredients when the complete formulation meets the nutritional requirements of the species and life stage.

Health and safety

  • Tuna farm

    Why choose farmed fish and shrimp?

    Farmed and wild seafood both contribute to global food supply. The appropriate choice depends on the species, production or fishery, origin, season, product and the environmental and social factors considered.

  • Tilberedt torsk

    Are farmed fish and shrimp healthy to eat?

    Yes. Farmed fish and shrimp can be nutritious choices, providing protein, vitamins and minerals and, depending on the species, long-chain omega-3 fatty acids such as EPA and DHA. Nutritional composition varies by species, feed, farming conditions and product.

  • Shrimp in hands

    Is it safe to eat farmed fish and shrimp?

    Yes. Farmed fish and shrimp produced for human consumption must meet applicable food-safety and production requirements. Food safety is managed across the value chain, from feed and farming to processing, transport, retail and food preparation.

Sustainability

  • Shrimp farm

    Why is aquaculture important?

    According to WWF, 85% of the world’s marine stocks are either fully exploited or overfished. Our planet’s population is forecast to reach 10 billion people by 2050, and with this growth will come a much greater demand for food, including seafood.

  • Sea farm

    Is aquaculture sustainable?

    Aquaculture plays an important role in meeting the growing demand for seafood. When well managed, it can produce nutritious food efficiently and contribute to a diverse global food supply.

  • Sea

    How is aquaculture regulated?

    Aquaculture is regulated through requirements that can cover farm approval, animal health and welfare, environmental impacts, feed, food safety, traceability and the use of veterinary medicines. The applicable rules and level of oversight vary by country, species and production system.

  •  Feeding the Future logo

    How are we contributing to feeding a growing global population?

    Skretting delivers safe and sustainable feeds and services worldwide to fish and shrimp farmers to ensure the responsible production of healthy and delicious food. We are focused on reducing our environmental footprint and increasing our positive social impact. 

  • Skretting feeds

    Are our feeds sustainable?

    Skretting works to improve the environmental and social performance of its feeds through responsible sourcing requirements, feed formulation, quality and safety controls, and continued research and innovation. These efforts support relevant United Nations Sustainable Development Goals and the responsible development of aquaculture.

  • Circular woods

    Are circular economy principles applied to aquaculture feeds?

    Yes. Aquaculture feeds can use suitable by-products and side streams from seafood, agriculture and other food-production systems. Before use, these ingredients must meet nutritional, quality, safety, regulatory and availability requirements.

Feed ingredients

  • Salmon carpaccio

    Do salmon and trout feeds contain colouring?

    Yes. Feeds for salmon and trout may contain astaxanthin, a carotenoid that contributes to the characteristic red or pink colour of salmonid flesh. Astaxanthin occurs naturally in the aquatic food chain and also has biological functions in salmonids.

  • Raw materials in bag

    What ingredients are in our feed?

    Aquaculture feeds provide nutrients such as protein, fats, carbohydrates, vitamins and minerals. These nutrients can come from marine, vegetable, animal and other approved sources. The ingredients used vary by species, life stage, product, market, regulatory requirements and availability.

  • Soy farmer

    Are our raw materials responsibly sourced?

    We work to source raw materials responsibly by setting approval and sourcing requirements for ingredients and suppliers. Depending on the ingredient and supply chain, these requirements can cover nutrition, quality, safety, regulatory compliance, traceability, and environmental and social risks.

  • Fish farmer with feed pellet

    Are animal by-products dangerous to human health?

    Animal by-products are not inherently dangerous to human health when they are legally permitted for use in aquaculture feed and meet the applicable safety, quality and processing requirements.

  • Feed pellets in hands

    Do feeds contain chemicals or preservatives?

    Feeds may contain authorised additives, including preservatives, when they serve a defined purpose such as maintaining product quality or stability. These substances must comply with applicable feed legislation and the permitted conditions and maximum levels for their use.

  • An aerial view of green algae

    Do we use novel ingredients in our 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. We are proactively working towards fully understanding the complexities of all new ;alternatives from sustainability, nutritional, quality and safety, regulatory and financial perspectives. For us, flexibility is essential. 

  • Pelagic fish

    Does aquaculture use more wild fish than it produces?

    There is no single answer for all aquaculture. The relationship between wild-fish inputs and farmed-fish production varies by species, life stage, feed formulation, feed efficiency and the calculation method used.

  • Oil

    What are fishmeal and fishoil, 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. By-products or trimmings from seafood processing are an increasingly large contributor to fish meal and fish oil production.

  • Feed pellets

    What is Skretting Nigeria's Food Safety Policy?
