More Atlantic salmon with less feed

The grower feed Premium is based on metabolic activators that improve the salmon’s utilisation of digestible energy.

The result is faster growth, higher yields and more marketable salmon.

The grower feed Premium is based on metabolic activators that stimulate a fish’s metabolism and improves the ability to utilise digestible energy. The result is faster growth, higher yields and more marketable salmon with higher levels of long-chain omega-3 fatty acids (EPA and DHA) in the fillet.

The beneficial effects of Premium have been documented in multiple Atlantic salmon feeding trials in global markets, but also locally in Tasmania. Generally, for every additional megajoule of digestible energy the specific growth rate can be improved by 3% and the feed conversion ratio reduced by 0.04. However, Premium has the potential to multiply these benefits. Meaning that production time can be shortened and less feed used.  

What are metabolic activators?

Our scientists at the Skretting Aquaculture Research Centre (ARC) had a breakthrough discovery. They found micro-ingredients that have an ability to increase the fish’s utilisation of digestible energy. These metabolic activators are natural substances present in specific raw materials. When combined correctly, these substances positively impact the fish’s physiology, for example more fat can be stored in the edible parts of the fish rather than being lost in the gutted parts of the fish following harvest and processing.

Increased levels of Omega 3

The worldwide supply of marine omega-3 fatty acids are limited and effective resource utilisation is therefore increasingly important. More fat is stored in the edible parts of the fish fed Premium, therefore the content of the healthy marine omega-3 fatty acids, EPA and DHA in the salmon fillet can be increased by 3 to 6 %.

Environmental benefits

As fish fed Premium require less feed to grow more(lower feed conversion ratio), it also has a positive contribution to reducing the amount of nutrient output being released into the surrounding waterways.

Strengthening farmed salmon efficiency

Farmed fish are highly efficient in utilising feed and retaining protein and energy. It is known that Atlantic salmon have better feed efficiencies compared with other domestic land animal protein sources such as chicken, pig and lamb. Premium has further strengthened the salmon’s position as the most efficient farmed animal.
