ABSTRACT

Water quality of aquatic ecosystem has been deteriorated due to industrial and domestic wastes. The aquatic ecosystem as a greater part of the natural environment is also faced with the threat of a shrinking genetic base and biodiversity due to discharge of effluents from industries. The persistence of toxic chemicals n aquatic environment becomes dangerous for the survival of fish and their food organisms. The quality of any water body is governed by its physico chemical factors. The monitoring of physico chemical characteristics of a water body is vital for both long and short evaluation of its quality. Microbiological analysis for fungi in water samples collected from fish ponds in Kumbakonam was carried out. The fungal genera isolated from the ponds were Aspergillus nigar, Aspergillus flavus, Aspergillus fumigate, Tinea urguium, Fusarium, Rhizopus species. The study revealed that the ponds were grossly contaminated with fungal organisms which poses a risk to human health thus of significant public health concern.

Keywords: Fish ponds, fungal isolates, Physico-chemical Properties.
