Abstract

This study aims to determine the content of heavy metals and their effects on fish (Barbodessp) tissues in the Brantasriver. Sampling was performed three times, namely in March, June, and September 2016. The samples of fish in this research that the upstream (Reservoir Karangkates) and downstream of the Brantas river (Kali Surabaya and Kali Jagir). Fish tissues (liver, gonads, and gills) were collected, analyzed the heavy metal and tissues histopathology, stained with Haematoxylin-Eosin. The results showed that all the tissues of fish that live in the upstream and downstream of the Brantas River contain hightheavy metals (Pb and Cr). The highest levels of heavy metals found in succession in the tissues liver, gonads, and gills. Hight levels of heavy metals that damage the structure of cells and tissues of all tissues of the fish. The most damage found in tissues containing the highest levels of heavy metals. Hight of heavy metals in the cells and tissue caused damage and necrosis cells.
