Composition and monthly variation in Zooplakton diversity at Laxmiwadi reservoir from Kolhapur District, Maharashtra (India)

Zoology

The present study was made to reveal the composition and monthly variation in zooplankton diversity at Laxmiwadi reservoir from Kolhapur district of Maharashtra, India. The study revealed that 16 species of zooplankton were noticed, belonging to 6 groups namely, rotifers, cladocers, copepodes protozoa and ostracods. Compositionwise copepode were noted dominant while based on monthly variation, rotifers and copepod,both occupy top place showing dominancy. All four groups have shown monthly variation during both the years and noted lower during monsoon season while higher during winter as well as summer season. Cladoceran group was an only exhibited its presence throughout the study period. Based on the present investigation it can be concluded that the water from the reservoir is tending towards pollution as polutant tolerant copepode and pollutant succeptible rotifer group were dominant.
