NEWS 20 FEED & ADDITIVE MAGAZINE March 2025 A newly released study conducted at the University of Las Palmas de Gran Canaria, in collaboration with Aker ǪRILL Company and the University of Stirling, highlighted the benefits of dietary krill meal inclusion for gilthead sea bream (Sparus aurata) juveniles. This study was funded by AǪUAEXCEL3.0, under the TNA program. The study demonstrates that krill meal can improve nutrient utilization, optimize feed efficiency, and boost resilience against oxidative stress, contributing to a more effective aquafeed. The study reveals that including krill meal in the diet significantly enhances fish health and stress tolerance, particularly during crowding challenges. This aligns with previous aquafeed trials with krill meal, reinforcing the ingredient’s potential to drive both sustainability and efficiency in the aquaculture industry. Gilthead sea bream is a highly valued species for aquaculture. However, crowded farming conditions often lead to oxidative stress, which affects fish health and growth. While traditional fish meal has been the cornerstone of aquafeeds, its fluctuating supply and cost are driving a greater need for more sustainable alternatives.

This new feeding system technology is gaining traction amongst salmon farmers for its potential to reduce energy consumption, microplastic pollution, and sea lice exposure. While these systems offer promising benefits, BioMar has identified specific factors contributing to nutritional loss in feed delivered through submerged systems. According to the statement, internal trials have shown that several factors can drive nutrient degradation. 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 extensive experience with the ORBIT product range and POWER grower diets, BioMar has made significant progress in understanding how raw materials and production processes impact feed performance in submerged environments. Early validation trials conducted on commercial systems have delivered promising results, giving BioMar a strong foundation for further development. “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.” Read more>> BioMar investigates ideal aquafeed for waterborne feeding
