Fish oil, chemical storage place for the world's seas

In Esbjerg, the biggest port on the Danish North Sea coast, a terribly bad smell emerges from the huge 999 fishmeal factories. The workers drop an enormous vacuum pump into the hold of a gigantic trawler. Billions of small fish (blue whiting) are then processed in a gigantic industrial process that smashes, grinds and boils them. This mixture is then separated into fish oil and fishmeal pellets. The fishmeal is for pigs, fowl and salmon farms. The oil is intended for food supplements, salmon farms, the margarine industry and for paint and varnish producers. So many small fish are caught that there is a surplus. Why? Salmon farms today are looking for vegetable sources of protein and omegas. Because blue whiting is too polluted. Solution for the 999 factories? Part of the fish oil is used as fuel for power stations.
