Fish-feed producer Skretting on Tuesday debuted its new transfer-feed concept, which allows fish to grow faster and larger.

The concept includes diets of Skretting’s Nutra Supreme and Spirit Supreme fish feeds. Both products involve strengthening fish with betain, nucleotides and beta-glucans. Also included are substances that help the fish cope with the transfer from freshwater to saltwater as well as lice protection, consisting of substances that make it difficult for lice to attach themselves to the fish.

According to Skretting, feeding salmon Nutra Supreme in the last five to six weeks before transferring the smolt to sea, and Spirit Supreme in the first five to six weeks once transferred, helps the fish reach full appetite faster.

“This will have an important compound interest effect on growth, which means that each fish is a little bit bigger by the time it is ready for harvesting. Calculations show that from 500,000 smolt you can expect over EUR 125,000 in improved sales revenues and at the same time lower production costs,” said Roar Sandvik, Skretting Norway product manager. “With the new transfer feeds RGI (relative growth index) goes from 0 to 100 in around 20 days. The days gained here have a positive impact on the bottom-line result.”
