A method for increasing the yield of microalgae and the yield of the product produced by the microalgae is provided. The method includes: performing a change procedure on the CAM1 gene and/or calmodulin 1 encoded by the CAM1 gene in a microalgae, such that a change occurs in the nucleotide sequence of the CAM1 gene and/or the amino acid sequence of the protein encoded by the CAM1 gene in the microalgae to obtain an altered microalgae. The altered microalgae has an altered nucleotide sequence of CAM1 gene and/or an altered amino acid sequence of calmodulin 1. The altered microalgae have a higher growth rate and a higher product production rate and/or yield than an unaltered microalgae.
