Community-Led Circular Blue Green Solutions for Low-Salinity Areas
MarinCircleBlue works with communities in the Hardanger region to link integrated multi-trophic aquaculture (IMTA) with circular blue-green value chains, turning harvested low-trophic biomass into agricultural biostimulants. Combining community co-design, an IMTA pilot, biostimulant trials and dissemination, the project will reduce fjord nutrient pressure and connect aquaculture with agriculture.
Hardangerfjord is a low-salinity system under nutrient pressure, with salmon farming as the dominant cause and a eutrophication risk if production grows. The sector is at a standstill after the County Governor rejected new applications. Farmers want documented effects from biostimulants, and local low-trophic knowledge is limited.
