The freshwater amphipod Gammarus balcanicus is one of the most widespread crustacean
species in Serbian streams. It usually inhabits highland mountainous streams and brooks (about 600-
1000 m a.s.l.), with clear and well-oxygenated waters. G. balcanicus shows intolerance to high level
of nitrite and phosphate concentration. Since trout farming can lead to increse of these compounds, we
have chosen this species as bioindicator on the level of oxidative stress biomarkers. Samples were
collected from two upstream localities (L1 and L2) and two downstream localities (L3 and L4).
Superoxide dismutase (SOD), catalase (CAT) and glutathione S transferase (GST) activities have been
measured. First downstream locality (L3) showed statistically significantly higher SOD and CAT
activities in relation to upstream localities (L1 and L2), whereas the GST activity was unchanged.
Increased antioxidative enzyme activity registered at the first downstream locality comes as direct
consequence of the increase in phosphates and nitrates in the localities down the trout farm, due to the
increased concentration of fish feces and the remains of fish food. This proves that antioxidative
defense enzymes as biomarkers and Gammarus balcanicus as model organism can be considered
excellent bioindicators of the river ecosystems’ pollution as the result of fish farming.
