The most important reason for preferring chlorophyll-a in phytoplankton biomass determination is due to a main photosynthetic pigment in all photosynthetic organisms while other algal pigments (chlorophyll b and c carotenoids and phycobillins) have limited distribution and are therefore considered as secondary pigments (Akpan 1994).
