What is fish feed made of?

Publish date: January 10, 2009

The fish feed of today consists of several different ingredients. Earlier only marine raw materials where used in the production of fish feed. But a growing aquaculture industry has led to a trend where more and more of resources comes from vegetable raw materials. Now the Norwegian authorities also open for the use of animal ingredients and therefore we will probably see that the proportion of marine resources will be reduced further. The table below shows the composition of the "traditional" fish feed (Waagbø et al., 2001) compared to a feed from 2007 (Skretting, 2008). The use of marine ingredients has been reduced from 68 to 52 percent of the raw materials used in marine origin.

Bellona’s new working paper analyzes Russia’s big LNG ambitions the Arctic

In the midst of a global discussion on whether natural gas should be used as a transitional fuel and whether emissions from its extraction, production, transport and use are significantly less than those from other fossil fuels, Russia has developed ambitious plans to increase its own production of liquified natural gas (LNG) in the Arctic – a region with 75% of proven gas reserves in Russia – to raise its share in the international gas trade.
