• Abstract:

  In the state of Morelos there are more than 164 temporary and permanent aquatic systems, as available water resources for carrying out different activities. For this reason, this work aims to identify the zooplankton species of the water resource, as food for extensive aquaculture activities. Zooplankton samples were taken in lentic aquatic systems from February 2000 to December 2010. 130 bodies of water were georeferenced, classified as permanent (76) and temporary (54), located between 891 to 2860 masl. The largest number of aquatic systems was located in the municipalities of Tetecala (17) and Tepalcingo (15). The recorded species corresponded to 144 rotifers, 35 to cladocerans and 13 to copepods. The most diverse and frequent rotifers were species in the genera Brachionus, Lecane, Keratella, Trichocerca, and Cephalodella. The dominant cladocerans were Diaphanosoma cf. brachyurum and Moina cf. microra. Regarding the copepods, Leptodiaptomus cuauhtemoci and Hesperodiaptomus morelensis, endemic species and from cyclopoids to Thermocyclops tenuis and T. inversus, Eucyclops agilis.
