Study of periphyton from Kayadhu river system (Maharashtra) for aquaculture practice

Abstract: Periphyton is a mixture of organisms attached to underwater substrates. The present study was carried out on diversity of periphyton on Kayadhu river system of Kalamnuri dist. Hingoli of Maharashtra. For the study sample was collected from the irrigation canal of Kayadhu river system and preserved for analysis. From the results it was observed that the periphyton sample has different genera of class Chlorophyceae, different genera of class Bacillariophyceae and zooplanktons. The physicochemical parameters of river water were within the suitable range of aquaculture. The bacterial colony count was also done. The two types of bacteria were observed and the total count of bacteria was 165 ± 5 per ml of water. The study shows that this irrigation canal of river can be utilized for the periphyton based aquaculture
