The present study is aimed to investigate the morphometric measurements and body weight of fish that live in the Brantas River, East Java. The sampling method of fish was by capturing fish using nets, then morphometric measurements including fish weight. Sampling was carried out in two locations, including upstream and downstream of Brantas River in 2016. Furthermore, sampling for each location was repeated twice with 100 m distance differ. All data analysis were performed using SPSS version 21. The results showed that there was no significant difference (P> 0.05) from morphometric measurements to body weight of fish, except Barbonymus gonionotus and Barbonymus balleroides in both locations. In addition, the fish that live upstream of the river have a higher morphometric measurements than those living downstream of the Brantas river.
