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 />
