註釋Estimates of phytoplankton biomass and rates of production can provide a manager with some insight into questions concerning trophic state, water quality, and aesthetics. Methods for estimation of phytoplankton biomass include a gravimetric approach, microscopic enumeration, and chlorophyll analysis, Strengths and weaknesses of these and other methods are presented. Productivity estimation techniques are discussed including oxygen measurement, carbon dioxide measurements, carbon 14 measurements, and the chlorophyll method. Again, strengths and weaknesses are presented. (Author).
