The percentage of total biomass of both Cylindrospermopsis species varied between 34 and 81. Biological variables played an important role in this lake. Fish-stock was formed by native herbivorous species Dorosoma petenense, Bramocharax caballeroi, Astyanax mexicanus, and an introduced Oreochromis niloticus. Feeding activity of fish removed large species of algae and cyanobacteria as well as detrital remnants and zooplankton from the water. Smaller, inedible cyanobacteria remained in the water and formed the stable dominant portion of the phytoplankton. The lake would belong to the functional group SN.
