Feed producer reports ‘remarkable’ trial results

Feed producer Aller Aqua and marine ingredients supplier TripleNine have reported “remarkable results” from a feeding trial of newly hatched rainbow trout.

The trial followed research to identify components of marine raw materials with function to benefit performance in terms of fish health and growth.

From first feeding after hatch, rainbow trout were fed different test diets containing functional marine ingredients until they reached fingerling size.

Dr Hanno Slawski: Trials confirm benefits of concentrating functional ingredients.

Excellent survival rates

The functional ingredients led to positive effects on fish growth performance and health and provided excellent survival rates in the test groups, said the companies, which are both Danish, in a press release.

This fulfilled the initial aim of maximising feed performance through targeted use of the functional properties of marine ingredients.

“We appreciate that TripleNine, a well-known producer of marine ingredients, specialises in value-adding products,” said Aller Aqua R&D director Dr Hanno Slawski.

“The ones we have tested are nutritionally valuable fish feed ingredients but using them as concentrated functional ingredients increases their impact. Our trials confirm this.”

Starter feeds

TirpleNine’s chief commercial officer, Kenneth Storbank, said: “We are very happy that the trials confirmed our intentions with 999Vital, which is the name for the product.

“We have a good collaboration with Aller Aqua, and it is a good way for us to get our products commercially tested and solidly documented.”

Aller Aqua said 999Vital will serve as set functional ingredients in its starter feeds, and continuous testing will further evaluate effects in grow-out and broodstock stages of fish lifecycles for possible later application.

The companies said the ingredients increased sustainability because concentrating the functional ingredients in marine raw materials ensured minimum waste and optimum effect from fewer raw materials.

This reduced the aquaculture value chain’s reliance on marine raw materials, and at the same time, less waste ensured a better water environment.
