Biological recipient monitoring at the Södra Cell Värö pulp mill – fish and bottom macro fauna

Last changed: 13 April 2022

The impact by the Södra Cell Värö pulp mill’s waste water discharge on the local fish community has been monitored since 1983.

  • Survey fishing with a bottom trawl in the recipient area and in a undisturbed reference area. Five transects in each area is trawled five times, under a period of three weeks in September.
  • The area next to the outlet tube  are filmed, to analyse the biot in order to investigate the sediment conditions and the surrounding animal life.
  • Upstream migration of young eels (Anguilla anguilla) in the river Viskan is documented annually by means of traps in the river mouth.

The results from the biological recipient monitoring are reported annually.
