Abstract: The determination of the zooplankton biomass is the most essential part of the research on marine ecology. There are a wide variety of biomass measurements. According to the principles of these methods, four types can be classified: body-sized counting estimation, volumetric, gravimetric, biochemical analysis. Furthermore, the advantages and disadvantages of various methods were also discussed.
