Takes pictures of objects in the water sample
measures the dimension, volume and number of objects
Tracks the volume of the sample
Automatically classifies objects into groups
Computes abundance, volume and size of each object and group per unit volume
Exports data into EXCEL spreadsheet

Relatively high initial cost
Decreased resolution below 10 µm
Preserved phytoplankton samples have high number of detritus objects
Species identification can be limited
Field use must be in controlled environment
Requires dedicated staff time

Phytoplankton • Best for live phytoplankton collection • Good separation into taxa • Expertise needed to develop libraries and check
identification • Fast and easy sample processing
Microcystis • Best way to analyze colony biomass • Little expertise needed • Fast and easy sample processing
Zooplankton • Good separation into taxa • Little expertise needed • Fast and easy sample processing

FlowCAM is fast, easy and cost effective way to quantify phytoplankton, Microcystis and zooplankton into genera or taxa, but requires dedicated staff
