Aquaculture for all

Coppens launches fresh trout fry feed

Trout Formulated feed +3 more

A new range of starter feeds for trout, which aims to “provide key nutrients while improving water quality” has been launched by Alltech Coppens this week.

The Top fry feed range has been launched following extensive research by the Alltech Coppens Aqua Centre (ACAC) where it was shown to have “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.”

The feed is designed with trout hatcheries, in particular those based on RAS, in mind

“We are excited about this feed and its ability to deliver optimum nutrition,” said Dr Philip Lyons, global aquaculture research manager at Alltech Coppens. “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.

“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,” added Dr Lyons. “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.”
