Mercury is a dangerous pollutant in the aquatic environment. It is persistence and
in low concentration, it can be accumulated in aquatic organism. In high
concentration, however, it may negatively affects the organisms. The aim of this
research is to understand the condition of the liver of Hemibagrus nemurus Blkr.
that were treated with mercury. There were 2 treatments applied, control (0 ppm)
and the LC50 of the H. nemurus, which was 0.49 ppm. Total fishes use in this
study was 20, 10 fishes for control and 10 fishes for treatment. After being treated
for 96 hours, behaviour, morphological, and histological structure of the liver
were studied. Results indicated that the treated fish shown abnormality in
behaviour, it was frantic in the first day, become weaken and die within 96 hours.
There was irritation in the skin. By the end of the experiment the liver of the
treated fish was pale. Histological study shown that there were tissue abnormality
such as cloudy swelling, blood congestion, haemorrhages, and necrosis. There
were also black spots in the liver tissue and it is predicted as mercury
accumulation. Based on data obtained it can be concluded that the mercury
negatively affect the liver of H. nemurus .
