CORRELATION BETWEEN PHYSICOCHEMICAL PARAMETERS OF WATER AND FRESHWATER ALGAE

Abstract

Algal interactions with physicochemical parameters of some manmade freshwater ponds have been studied. Algal species and their correlation with physicochemical parameters in some manmade ponds were correlated. Algae and water samples were collected, preserved and analyzed using standard methods. Closterium sp. and Rhizoclonium hookeri Kuetz. were positively associated with the concentration of Fe, however they were negatively correlated (sensitive) to alkalinity, total dissolved solids and electrical conductivity. Stichococcus bacillaris , Naegeli, Staurastrum rotula Nordst. and Sphaeroplea sp. had significant positive correlation with biochemical oxygen demand (BOD), Mn, and Mo levels in the water. Pseudouvella americana (snow) Wille. and Scenedesmus quadricauda (Turp.) de Breb. showed a close positive correlation with alkalinity but were sensitive to Fe, BOD, Mn and Mo. The species reported here showed closed correlation with physicochemical factors in these freshwater ponds in Karauli.
