Already today 49% of the world production of food comes from our oceans, this will need to increase over time due to the possibility to increase the food production on land is limited. At the same time have we used our oceans as a dumping station that reduces our potential to use our oceans and primarily our coastal regions around the world for food production, eutrophication cased by to much nitrogen and phosphorus being poured out from farming, wastewater, industry etc. 

In Norway they have understood the challenges and the risk that their 2nd biggest industry is facing, the fishing industry will see a reduced capacity to use fish farming if they do not remove the fish sludge from the fjords.

A network collaboration called ARAL in Norway has proven the potential to both collect the fish sludge but also extract the resources from it. Already today the methane can be extracted with a total potential of 2TW hour of energy if all fish sludge would be collected. But there is even more potential, the fish sludge contains also 9,000 tons of P that today is waste every year. This is more P than Sweden as nation imports as a food phosphate. 

Norway is the frontrunner in this, but the potential is huge all over the world, Norwegian salmon industry is only 2% of the world total fish farming. The situation is starting to be critical in Canada, Chile, Scotland, Lake Victoria etc.
