Winter nutrition that keeps your trout growing

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.

Available in both EFICO Enviro 920 Advance Winter and EFICO Alpha 790 Winter.
