What ingredients are in Skretting’s fish and shrimp feeds?
Fish and shrimp have specific nutritional requirements like humans - protein, fat, carbohydrates, vitamins and minerals. The nutrients in our feeds come from a range of natural raw materials, depending on the species and the life stage. Typically, feeds can contain a mix of marine (fishmeal and fish oil) vegetable (for example wheat, soy, rapeseed, sunflower and faba) and by-products from human consumption of land animals. Increasingly, as ingredients become available we are looking to include more novel raw materials, such as insects, algae, proteins from single cell organisms such as yeast, and even waste.
Aquaculture feeds, most commonly provided in the form of dried pellets, contain all of the essential nutrients needed to keep fish and shrimp healthy and growing and support the needs over the different life stages.
Fishmeal and fish oil are two of the more commonly known marine ingredients sometimes used in aquaculture feeds. Fishmeal 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. Offcuts not suitable for human consumption, resulting from seafood processing are an increasingly large contributor to fishmeal and fish oil production. Skretting has policies in place for sustainable sourcing of raw materials.
One of the most innovative developments from Skretting over recent years is the development of fully flexible feeds, made possible through an innovative concept we call MicroBalance. Substituting ingredients is not as easy as you might expect - micronutrition must be fully understood an accounted for to ensure health and growth are not compromised. Many years of R&D at Skretting Aquaculture Research Centre (ARC) have ensured that we can now make feeds that are fully flexible when it comes to raw materials, satisfy the needs of the fish and shrimp, without negative effects on animal health and performance.
Skretting recognises that one of the most positive impacts it can have in the context of sustainability is to ensure that it manufactures its feeds from responsibly sourced raw materials. We therefore endeavour to improve the sustainability of our purchasing and feed formulas.
