Abstract

In the present study effect of various concentration of Nuvan ( 2,2 of dichlorovinyl dimethyl phosphate) exposure on 7 days 15, 30 and 60 for many behavioural and morphological parameter in the fresh water fish H.fossilis. the objective of the present study was to observe behavioural and morphological changes in freshwater fish H. fossilis. At Higher concentration of nuvan fish showed alterations in morphological and behavioural responses specially erractic and jerky swimming frequent surfacing and ingulping, mucus secrection and increase in opercular movement and copious secretion of mucus all over the body.
