Winter nutrition that keeps your trout growing

Specialized BioMar feeds designed for performance, resilience, and efficiency in cold-water conditions

Winter brings real challenges for trout farmers. As temperatures drop, metabolism slows, appetite declines, and maintaining growth can feel like an uphill battle. BioMar’s winter feeds are developed to keep your fish progressing through the toughest months delivering reliable intake, efficient conversion, and strong resilience all winter long.

Our Winter edition feeds are formulated specifically for cold-water performance, helping secure feed intake, maintain fish condition, and support immune function when temperatures are at their lowest. With extra vitamins C and E and a winter-adapted nutritional profile, they help trout stay stable and ready for rapid growth when spring arrives.

    Wheat Gluten: A reliable protein and binder for fish feed

    Wheat gluten is a common ingredient in modern aquaculture diets, valued for a combination of nutritional and functional advantages. It isn’t a magic ingredient, but it consistently supports efficient feed production and healthy fish growth. One of its best-known traits is its strong binding ability earning it the occasional nickname “super glue.” This natural binding property allows many feed mills to reduce or even eliminate synthetic binders.

    Feathers with a future

    Every year, billions of chickens are processed for food - leaving behind mountains of feathers. While most see this as waste, aquaculture nutritionists see something else entirely: opportunity. These feathers, once destined for landfills, are now being transformed into a high-protein, sustainable ingredient known as feather meal.

    Vejen mod et bæredygtigt fiskeopdræt

    Their aquaculture journey began with curiosity sparked by an unused pond on his father’s land. With no prior experience in fish farming but a strong background in finance and business, Lauris Apsis saw an opportunity to create something meaningful. Recognizing sustainability as the key to long-term success, Lauris and his Finnish partner, Salmela-Yhtiot Oy founded Blue Circle (Zivs uz Ledus), a Latvian farm dedicated to producing premium Arctic char using cutting-edge recirculating aquaculture systems (RAS).

Disse udledninger, som nu spores under Science-Based Targets-initiativet (SBTi), stammer fra arealanvendelse og landbrugsaktiviteter snarere end fra energiforbrug.
