Abstract
Quite possibly of the most
essential biological boundary in surveying water quality is zooplankton
variety. They are believed to be expected signs of water quality since they are
extremely sensitive to changes in the climate. This research aims to examine
the zooplankton species composition in Chitradurga district's Mallapura lake
over the course of a single year, from January 2023 to December 2023. These
zooplankton were calculated using diversity indices like the Simpson Index and
the Shannon-Weiner Index. In this study, 31 species of zooplankton, including
05 groups, were identified: Protozoa, Ostracoda, Copepoda, Rotifera, and
Cladocera. There are 10 species of Cladocera, 12 species of Rotifera, 4 species
of Protozoa, 2 species of Copepoda, and 3 species of Ostracoda. However,
Cladocera, Protozoa, Ostracoda, and Copepoda follow Rotifera. The most
zooplankton species were found in the genera Rotifera and Cladocera. The
Shannon-Weiner Index was between 2.22 and 2.60, while, the Simpson Index was
between 0.78 and 0.95. The lake Shannon-Weiner and Simpson records demonstrated
moderate water contamination and moderate zooplankton variety. This increases
the lake's productivity and helps in the planning of successful fisheries management.
Consequently, after proper treatment, the water from Mallapura village is safe
for drinking and household use. The ongoing investigation showed that the
Mallapura lake is has a place with mesotrophic class and it is likewise
shielded from the wellspring of contamination.
