Alltech Coppens launched an improved range of innovative starter feeds for trout. Backed by extensive research at Alltech Coppens Aqua Centre (ACAC), TOP fry feed is shown to provide key nutrients while improving water quality.

Understanding the importance of early nutrition, Alltech Coppens advanced its range of starter feeds to support trout farmers in raising high-quality products for consumers. Research at ACAC shows that Alltech Coppens TOP fry feed has an optimized ratio between digestible protein and digestible energy (DP:DE). The result is better performance, higher protein utilization and lower ammonia excretion, leading to improved feed efficiency and better water quality.

“We are excited about this feed and its ability to deliver optimum nutrition,” said Philip Lyons, global aquaculture research manager, Alltech Coppens. “Not only producers are able to improve performance during a critical phase, but they can also do so with an eye toward sustainability.”

Trials conducted at ACAC have shown that by reducing the digestible protein to digestible energy ratio (DP:DE) in every size of the TOP line, the protein utilization by juvenile trout was improved. Further research shows that TOP allows the bacteria in biofilters to be more efficient, as they have to convert less ammonia per kilogram of feed. This is beneficial for RAS systems and any trout hatchery.

Two of the largest sizes of TOP feed are now available as micro-pellets that combine a slow sink rate paired with high water stability. This allows trout fry more time to eat while the water is kept cleaner.

“The Alltech Coppens research and development team has put innovation and the farmer at the center of trials, leading to the creation of the next generation of starter feeds for trout,” added Philip Lyons. “The TOP line of products rounds out a suite of high-quality feeds designed to optimize the health and performance of fish throughout the production cycle.”
