Fish sampling is carried out at each station using a plot of 10 x 10 m2. The number of plots at each station is 9 plots with a total of 45 plots. The results showed that the diversity index (H') value of fish in the Lokop river was 2.39 in the moderate category and the distribution pattern of fish in the Lokop river has a uniform pattern and clusters.
