Norwegian company Skretting said that the new transfer concept, which includes the new diets Nutra Supreme and Spirit Supreme, give seawater fish farms faster growing fish and more kilo fish to harvest. The company states that feeding salmon Nutra Supreme in the last five to six weeks before transferring the smolt to sea, and new Spirit Supreme in the first five to six weeks in the sea will help salmon reach full appetite much faster.
Roar Sandvik, Product Manager in Skretting Norway, explains that 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. He further said that as per calculations from 500,000 smolt one can expect over €125,000 in improved sales revenues and at the same time lower production costs.
Sandvik told that following transfer to sea, there is always a critical period before the fish reach full appetite. The length of this period has a significant impact on the end result. He added that the new transfer push 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.
According to the company Nutra Supreme and Spirit Supreme take transfer feeds one step further with a concept that involves strengthening the fish with betain, nucleotides and beta-glucans. Active substances which affect organs and processes so that the fish cope with the transfer from freshwater to saltwater even better are also included.
