EFFECT OF PHYSICO-CHEMICAL CHARACTERISTICS ON CYANOBACTERIAL DIVERSITY IN THREE FISH CULTURE PONDS OF MEERUT REGION

Abstract

Cyanobacteria provide an extraordinarily wide-ranging contribution to human affairs in everyday life. Both the beneficial and detrimental features of Cyanobacteria are of considerable significance as they are important primary producers and their general nutritive values is high. The occurrence of a particular genus and species of Cyanobacteria around the world is apparently affected by regional differences in water chemistry and climatic conditions. The ponds, taken into consideration for the present study are located in District Meerut. All of these ponds are very important for commercial point of view. Interference of local people, as they bath, wash their clothes and utilise the water for agriculture and other purposes, leads to fluctuations of physico-chemical characteristics which affect the growth and diversity of Cyanobacteria.
