The Nutrient Loop in Aquaculture
Starting our journey in Älvkarleby,
We follow the route the wild salmon would naturally take... if 41 dams didn't block the river waterway.
We see how SLU are involved in the cycle to keep young salmon in circulation and discover how the problem is compounded by what has happened in the lakes upstream. Where a combination of climate change and the dam has completely caused a “game changer” in the former river lake, by a dramatic loss in the beach zoon followed by loss of nutrients. Which in next step result in power of the natural food chain to support vital fish populations and production of large and healthy fish..
