In the Main Canal Network (MCN) of the Danube-Tisza-Danube Hydrosystem (HS DTD), the canals Kosancic-Mali Stapar and Vrbas-Bezdan are distinguished by their high production of aquatic and semi-aquatic vegetation. For that reason, grass carps stockings (C. iddela) were performed in selected locations. In 2006 and 2007, total vegetation cover in the Kosancic- Mali Stapar canal near the village of Ruski Krstur, which had been stocked with grass carps (experimental area) was 2-2.5 times lower than it was in the section that had not been stocked. Total vegetation cover was 10-30% in the former and 40-60% in the latter location. On a location near the village of Kruscic, where aquatic vegetation mowing was practiced instead of fish stocking, total vegetation cover ranged between 30 and 60%. In the Vrbas-Bezdan canal, total vegetation covers in the experimental areas near the villages of Sivac and Sebesfok were 10-30% and only 10-15%, respectively. Total cover in the control location (the Stapar bridge) was 40-60%. The reported values are for a good part the result of bioremediative effect of grass carp.
