In the initial phase from 1991 to 1995, nine sampling points were established in the northern part of Taihu Lake, covering an approximate area of 1000 km². From 1995 to 2004, the monitoring effort expanded to encompass the entire Taihu Lake while maintaining monthly monitoring at the original sites. The number of monitoring points increased to 14 during this period, allowing for more representative monitoring of Taihu Lake. Starting in 2005, the monitoring sites were further expanded to 32, ensuring coverage of the main ecological types within the larger area of 2338 km². The original sampling depth was 50 cm underwater. However, from 2006 onwards, a mixed sample from the upper, middle, and lower layers was collected. Stations 0, 1, 3, 4, 5, 6, 7, 8, 10, 13, 14, 16, 17, and 32 of the Taihu Lake Station conduct monthly monitoring, with sampling taking place in the middle of each month. The remaining stations conduct quarterly monitoring, with sampling occurring in February, May, August, and November in the middle of the month. Samples of phytoplankton were inspected under Zeiss Axiovert 135 microscopes with biomass calculated from biovolume as (1mm3 biovolume = 1mg/L biomass), unit mg/LCitation(s)
