Alltech Coppens launches new TOP fry feed for trout


Alltech Coppens new TOP fry feedprovides key nutrients to trout during its early life stages while improving water quality.



Alltech Coppenslaunched 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 optimised ratio between digestible protein and digestible energy (DP:DE). The result is better performance, higher protein utilisation and lower ammonia excretion, leading to improved feed efficiency and better water quality.


Dr Philip Lyons, Alltech Coppensglobal aquaculture research manager said not only are producers 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 utilisation by juvenile trout was markedly 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.


Dr Lyons addedthat the Alltech Coppens research and development team has put innovation and the farmer at the centre of trials, leading to the creation of the next generation of starter feeds for trout.


He said the TOP line of products rounds out a suite of high-quality feeds designed to optimise the health and performance of fish throughout the production cycle.
