The latest research from BioMar has shed light on the aquafeed challenges associated with waterborne feeding systems, the feed firm said.

This new feeding system technology is gaining traction among salmon farmers because of its potential to lower energy use, reduce microplastic pollution, and minimize sea lice exposure. While these systems offer promising benefits, BioMar said it has identified specific factors contributing to nutritional loss in feed delivered through submerged systems.

Internal trials have shown that several factors can drive nutrient degradation, BioMar said. These factors vary in intensity and underline the complexity of creating an aquafeed that performs consistently under the unique conditions of waterborne feeding.

Drawing from in-house experience of feed production, BioMar has made significant strides in understanding how raw materials and manufacturing processes influence feed performance in submerged systems. Early validation trials on new commercial setups have shown encouraging results, providing a solid foundation for further advancements, it said.

“Through our research, we have a better understanding of the complex dynamics of waterborne feeding,” said Ewan Cameron, product marketing manager of the grower category for BioMar. “These insights allow us to enhance our feed formulations and production techniques to reduce nutrient loss significantly.”
