Molina Agarwal

Abstract :

 The Impact of fluoride on aquatic flora and fauna is increasing day by day, as in the case of fish their population is getting reduced gradually. Fish population and their production have been much affected in term of both quantity and quality. I(n aquatic habitats fish are the most sensititive organism and get affected even upon a mild change in the surroundings. Static bioassay were performed for evaluation of short term (96 hours) acute toxicity of fluoride to fresh water teleost Heteropneustes fossilis visible sign of poisoning were expressed as frequent jumping, erratic movement followed by convulsions. Rapid rate of operculum movement accompanied by occasional gulping of air also recorded. Sensitivity factor showed that Heteropneustes fossilis is very sensitive to fluoride.
