ABSTRACT

 

Exposure to UV- B radiation has been found to have negative effects on aquatic and terrestrial organisms. This study was performed with the objective to measure the solar ultraviolet-B radiation and study its effect on fish larva. Adverse effect of different intensities of natural solar and artificial ultraviolet- B radiation on fish Barilius bendelisis and Nemacheilus botia in presence of retene and riboflavin was investigated. Solar ultraviolet-B, intensity shows seasonal and altitudinal variations. Ultraviolet-B radiation level was lowest in month of December - January and highest in the month July
