Den fantastiske villaksen (2018)

The Salmon Story follows angler and environmentalist Kenneth Bruvik as he sets out on a mission to find out why the population of Atlantic salmon is decreasing so rapidly. Norway once had a large wild Atlantic salmon population comprising nearly one third of the world's total population. But during the last 30 years, salmon numbers have decreased from one million to 500,000. Meanwhile, Norway's aquaculture industry has become its second largest export industry. Currently, aquaculture production creates approximately 400 million farmed salmon in 6,000 open net pens. Norway's wild salmon population would fit into only three of these net pens. The Salmon Story explores the unsustainability of the aquaculture industry and its severe impacts on the environment. Wild salmon are facing several critical threats, one of the largest being the escape of farmed salmon. When escaped salmon spawn with wild salmon, their survival rate decreases. The growth of high-density salmon farms has also increased the occurrence of salmon lice infestations in both farmed and wild salmon populations. Sea lice are parasites which attach to a fish's skin, fins, and gills. By law, sea lice may kill up to 30% of regional wild stock before area farms are required to reduce their production.
