The
Euglenophyceae algae consumption, in this period, is possibly a consequence of its abundance in lentic environments, as well as in many other aquatic ecosystems (Bicudo & Menezes, 2006).
Limnological conditions reported in Panati Pond such as nutrient availability, and high electric conductivity, and shallow lakes, and extensive bed of macrophyte promoting the development of species of the genus
Euglenophyceae (Wetzel, 2001; Reynolds et al., 2002).
Phytoplankton were represented by the classes Cyanophyceae (49.1%), Chlorophyceae (38.0%), Haptophyceae (6.3%), Bacillariophyceae (3.2%), Dinophyceae (2.3%), and
Euglenophyceae (1.1%), and no significant difference was observed among treatments (P > 0.05).

As classes
Euglenophyceae e Cyanophyceae estiveram bem representadas nas tres epocas de avaliacao (Figura 2D, 2E e 2F).
The other groups were Chrysophyceae (12 taxa), Dinophyceae (9 taxa), Cryptophyceae (7 taxa), and
Euglenophyceae (6 taxa).
