BioMar outlines phased BioRetain rollout

BioMar is set to introduce BioRetain gradually across its product portfolio, adapting the concept to different species, markets and production systems as it seeks to address varying nutritional and commercial requirements in aquaculture.

The approach will allow the company to apply BioRetain according to the specific objectives of individual feed solutions, creating opportunities to support performance while offering greater flexibility in formulation.

“BioRetain represents an important step in how we develop feed solutions for the future,” said Carlos Diaz, chief executive of BioMar Group. “Greater formulation flexibility strengthens our ability to respond to changes in raw material availability while continuing to deliver the biological performance and feed efficiency our customers expect.”

The flexibility of the concept means its application will depend on the intended outcome of each feed. Where production priorities focus on maximising growth and yield, BioRetain can be incorporated into performance-focused formulations. In other situations, the emphasis may be on maintaining biological performance while improving cost efficiency.

BioMar plans to implement the concept progressively rather than introduce a single, uniform approach across its entire portfolio. Feed solutions will be adapted to reflect differences between species, market conditions and production requirements, allowing the company to target applications where the concept can deliver relevant benefits.

The phased rollout is also intended to accommodate developments in scientific understanding. BioMar said the concept would continue to evolve as research advances and knowledge of nutrient utilisation improves.

This ongoing development could influence how BioRetain is incorporated into future formulations, with applications refined according to emerging evidence and the needs of individual production systems.

For feed producers and aquaculture operators, the approach highlights the importance of balancing biological performance with formulation costs. Different farming systems and commercial objectives can require different nutritional strategies, making flexibility an important consideration when developing feed products.

“Growth is not simply about supplying more protein or more energy,” said Simon Wadsworth, global R&D director at BioMar.

“What matters is how fish and shrimp retain and utilise those nutrients, turning more of every kilo of feed into performance and value for the farmer.”
