Resumo: | The different growth stages of three marine unicellular algae used in aquaculture, Isochrysis galbana, Chaetoceros calcitrans forma pumilum and tetraselmis suecica have been studied for 50 days under controlled culture conditions using a particle meter. At the same time, the size spectrum of the cells has been determined using a C 1000 scanner. The exponential growth stage is 11 days in the first two species, and 13 in the last one. Chaetoceros calcitrans forma pumilum is the smallest with an average size of 3.5 µm. Its cellular volume is constant. The average size of Isochrysis galbana is 4.5 µm. An increase of the cellular volume is observed through its stationary stage. The modal size of Tetraselmis suecica is 8 µm.  Again, an increase in the cellular volume is observed during its stationary stage.
