The open water area of the reservoir was rich in phytoplankton and had hypertrophic characteristics, but inside the reed stand (80% of the surface area) phytoplankton biomass and production were substantially (30-50 times) lower. The algal removal efficiency of the lower Kis-Balaton reservoir was 96%. The reservoir had a considerably smaller effect on bacterioplankton removal than on the phytoplankton. The decrease of biomass and production of bacterioplankton in the through-flowing water was approximately 60%. Inside the reed stand the biomass and the production of planktonic bacteria exceeded that of the phytoplankton by several times, suggesting that the release of biodegradable dissolved organic (humic) substances from macrophytes stimulated the metabolism of bacterioplankton. The significant reduction of phytoplankton inside the dense reed stand was primarily the result of the shading effect of the reeds. In the open water area a shading experiment demonstrated that a 1-week residence period for planktonic algae in the reed-covered area was sufficient for their complete elimination. The decomposition of planktonic algae, reed material and the lack of primary production inside the reed stand created oxygen-deficient and phosphorus-rich conditions during the vegetative period. These results suggest that reed-covered water bodies can effectively retain suspended solids and planktonic algae, but because of decomposition processes they cannot retain biologically-available phosphorus.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Phytoplankton and bacterioplankton production in a reed-covered water body","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"shallow reservoir; Phragmites australis; shading effect; humicsubstances; phytoplankton; bacterioplankton; phosphorus retention","OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2003-10-01","SecASFANote":"Phyto- and bacterioplankton production in the reed-covered Lake Balaton (Hungary)","ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000185434700002","VABBcode":null,"OpenAcc":1,"DOI":"10.1016/s0304-3770(03)00090-1"},"refs":null,"anarec":{"AnaID":40529,"PubliDate":2003,"Pagination":"99-110","XtraPublOfAnaID":null,"ISBN":null,"Volume":"77","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42195,"SerRR":"Aquatic Botany.
