Highest month-wise prevalence (p=0.09878,p<0.05) reported May (30%), then by February October each (26.6%) while lowest August (13.3%). (p=0.9723, p<0.05) summer season (26.6%), winter (20%). Adults highly (p=< 0.0001) (63.7%) followed sub-adults (13.2%) no infection found juvenile specimens. Females had higher (p=0.0277, p>0.05) (28.8%) than males (16.6%). Fishes lower highest (p=0.0029, P>0.05) (31.7%) (16.5%) observed collected (9.87%). Present study address that intestine trout has a long term relationship call as natural cyprinids zoonotic risk human.
