 abstract={A 6-day in situ water exposure in open 40-l polyethylene bags did not show physico-chemical deformations of the lake habitat. Phytoplankton production in bags was almost 50% lower in comparison with open lake water. Phytoplankton biomass and contribution of algal groups examined approximated in both environments. Six-hour (100 ml bottles, 40-l bags) and 6-day (40 l bags) enrichment experiments (in P, N or P and N together) were conducted. The 14C assimilation by phytoplankton in variously enriched water depended on the duration of exposure in situ and the kind of enrichment.},
