Distribution Variables in Macroinvertebrates from Ashvi Reservoir, Sangamner, Maharashtra, India

Anant J. Dhembare

The present work records distribution variables as frequency accurance, relative density, relative frequency, relative abundance and important value among macroinvertebrates from Ashvi reservoir. These variables varied species to species. A total 17 species of macroinvertebrates belonging to Mollusca, Arthropoda and Annelida were noticed. They constituted dominant Mollusca [48.1%], followed by Arthropoda [39.7%] and Annelida [12.2%]. The class wise density followed as Gastropoda-27.5%, Bivalvea-21.4%, Insecta-22.6%, Malacostraca-15.9% and Polycheta-12.6%. The distribution variables and water parameters were discussed.
