NORWAY-SALMON FARMING.

Results from a series of salmon feeding trials run by Skretting Aquaculture Research Centre (ARC) revealed a new low limit for fishmeal in salmon grower feeds. The trials, conducted on fish from 1 to 5 kg, showed excellent growth and a low feed conversion rate (FCR) on salmon given feed with 15% fishmeal and no land animal protein.

Dr Alex Obach, Managing Director of Skretting ARC, gives some details. "We used three feeds and the best results came from an experimental feed using only 15% fishmeal together with active ingredients we are currently investigating. The two other feeds were a more conventional feed with 25% fishmeal and a similar experimental feed using 15% fishmeal but without the active ingredients. The results totally change our previous belief that the lower limit for fishmeal was 25% unless land animal proteins were used. At present, that is not possible for salmon production in Europe."
