ARTICLE 52 FEED & ADDITIVE MAGAZINE February 2025 As aquaculture expands to meet the growing global demand for fish protein, feed formulations have evolved to include alternative ingredients such as plant-based proteins, reducing reliance on fishmeal and fish oil. However, alternative ingredients often present challenges, including reduced palatability and digestibility, which can result in lower feed intake, inefficient nutrient absorption, and increased waste. While alternative feed ingredients are becoming more common, fish meal is still widely used in aquafeeds, particularly in high-performance formulations. Differences in the feeding habits of freshwater fish species play a significant role in addressing these challenges. Largemouth bass is a carnivorous fish species, with a natural preference for animal-based protein sources, which makes them more reliant on high-protein diets that closely mimic their natural feeding behaviour. This reliance on protein-rich feeds often necessitates the inclusion of fishmeal in their feed. In contrast, tilapia are omnivorous fish with a natural inclination toward plant-based materials in their diet, enabling them to more readily accept feed “Lyso-phospholipids, also known as lysolecithin, are produced through the hydrolysis of lecithin, which removes a fatty acid molecule from phospholipid structures. This modification increases their hydrophilicity, making LPLs highly effective emulsifiers. When incorporated into aquafeeds, LPLs disperse dietary fats, increasing the surface area available for lipase action and enhancing nutrient digestion.” LYSO-PHOSPHOLIPIDS ENHANCE GROWTH PERFORMANCE AND FEED EFFICIENCY IN FRESHWATER FISH Dr. Guillermo Bardera Global Technical & Scientific Support Manager Aquaculture Nutrition Adisseo Marleen Dehasque Global Product Manager Aqua Nutrition Adisseo Dr. Waldo G.
