The marine microalgae culture system has evolved since the beginning of aquaculture, where large volumes were produced to attain an adequate biomass, extensive culture, intensive continuous cultures and finally the semi continuous systems that are presently used, using photo bioreactors, which optimize the use of light and nutrients to attain optimal microalgae production in much lower volumes and shorter times, reducing space and time required, as well as costs related to material and hand labor.
The objective of this experiment was to validate an automatic sperm count normally used in the veterinary industry (SCA), for its use in microalgae count. Results indicate that the SCA is valid for this use. Furthermore, SCA can be of great utility and accuracy, when configured for the analysis of quality parameters in the intensive microalgae culture.
