Biomass and primary production of Cladophora glomerata (L.) Kutz. in the Neva Estuary

The dynamics of the biomass, primary production, and P/B ratio of floating and attached forms of green filamentous alga Cladophora glomerata (L.) Kutz. was studied for the shallow water littoral area of the Neva Estuary in 2003-2006. The biomass of the floating algae constituted up to 70% of the total biomass, and the primary production reached up to 90% of the total for the depths of 0-1 m from the middle of July to the end of August.
