Study on phytoplankton biomass Ⅱ. Net-phytoplankton measurement biomass estimated from the cell volume in the Jiaozhou Bay

Based on phytoplankton cell measurement biomass from the cell volume,the net-phytoplankton measurement biomass in the Jiaozhou Bay is calculated,and the anniversary variety is compared with the cell counting result,the dominant species in the Jiaozhou Bay are analysed.It shows that,during the investigation,there are two cell concentration peaks (the main peak is in January 1996 and the vice peak is in September 1995),but the peak of the measurement from the cell volume appeared 0nly once (in August 1995); the dominant species analysis shows that the above-mentioned difference is from the difference of the phytoplankton community and phytoplankton cell volume during the investigation.The phytoplankton measuremem biomass estimated from the cell volume method is not only more precisely estimating the standing stock but also represents the energy flow at the phytoplankton community and population level.
