LSG is focused on that we shall operate a sustainable activity, this also involves the feed<br />
raw materials we use. LSG has a comprehensive criteria specification that must be met<br />
by our feed suppliers in regard to the origin and sustainability of the raw materials. LSG<br />
is Global Gap certified; which also makes demands of contributing factors such as feed.<br />
The marine raw materials we use shall only originate from regulated fisheries and we<br />
shall not use fishmeal or oil produced in competition with direct human consumption.<br />
Fish in – Fish out<br />
There is intense focus among NGO’s and a number of our customers on “fish in - fish<br />
out” (FIFO), i.e. how much wild fish does it take to produce a kilo of <strong>salmon</strong>. There are<br />
many ways to do the sums and many figures are batted about. The result is dependent<br />
among other things on the fat content of the wild fish which meal and oil are produced<br />
from (can vary from 3-12%), how much marine protein and oil are in the feed, how<br />
high a feed factor we have (kg feed used per kg growth) etc.<br />
The industry is, in cooperation with the World Wildlife Fund (WWF), on the way to<br />
reaching agreement on how FIFO should be calculated (SalmonAquaculture Dialogue). A<br />
typical Lerøy <strong>salmon</strong> will in accordance with this method have a FIFO for marine protein<br />
equal to ca. 0.5, or for every kg of marine protein we give the <strong>salmon</strong> we get 2 kg in<br />
return – accordingly a net producer of marine protein. FIFO for marine oil is ca. 2, or for<br />
every kg of fish oil we give the <strong>salmon</strong> we get 0.5 kg in return. This is<br />
mainly due to the considerable difference in the fat level between the<br />
wild fish we produce oil from and the <strong>salmon</strong>. We can achieve a lower<br />
level through increased use of vegetable oils but then the level of<br />
EPA/DHA in the fish would be reduced.<br />
