Summary

Åland archipelago is an eutrophic area receiving nutrient inputs from numerous sources. Algae has increased in the area since the early 1990s. Hypoxia and anoxia occur frequently and have caused benthic mortality. Fish have decreased in abundance, biomass and diversity during the occurrence of algal mats.
