The 88 page report - "The OSPAR Comprehensive Procedure for the Norwegian West Coast - Eutrophication Status" (authored by Jarle Molvaer, Wenche Eikrem, Jan Magnusson, Are Pedersen and Torulv Tjomsland: http://www.sft.no/publikasjoner/2289/ta2289.pdf ) includes:

"In this assessment four features stand out:
1. A high increase in the nutrient load over the last 15-20 years. As this to a large extent is caused by increased discharges from the aquaculture industry, it also implies changes in two other features:

. A shift in the distribution, from point sources associated with cities or rivers: often combined - to far more diffuse loads from aquaculture farms...." (p5)

"The Hardangerfjord:

Nutrient load: The average anthropogenic nutrient load has increased by 70-80% during the last 10 years due to an increased production in aquaculture farms" (p45)
