ABSTRACT
Cyanobacteria are the pioneer oxygenic, gram negative photosynthetic prokaryotes distributed inalmost all conceivable habitats. Cyanobacteria exhibit great diversity of forms and functions. Gunupur is apart of the southern belt of Orissa, rich in Cyanobactrial biodiversity in paddy ecologies. The study aimed tocharacterize the abundance and occurrence of Cyanobacteria in various paddy fields of Gunupur, identifythe isolates and determine diversity indices in relation to the genera wise distribution .Average populationcounts of various locations brought out the major diversity among the locations sampled. This study indicatethe maximum occurrence and abundance of Oscillatoriaceae and Nostocaeae in all sites of the Gunupurand Stigonemataceae shows less occurrence.
