AB  - Lake Ludaš is a protected nature reserve in Serbia that has been the focus of scientific interest, due to
perpetual water quality deterioration that has led to consistent cyanobacterial blooms for almost five decades. To describe the possible effects of cyanotoxins on fish (Carrasius gibelio) inhabiting Lake Ludaš, several examinations were performed in November of 2018, including: assessment of water quality (physical and chemical parameters, as well as water microbiology), and assessment of several tissues of C. gibelio (micronucleus test, comet assay, and histopathological analyses). The water quality of Lake Ludaš has been categorized as class III, indicating moderate pollution. Physical and chemical parameters from November of 2018 seemed to be within acceptable levels. Examined fish tissues showed signs of DNA damage (highest in the blood, followed by the liver and gills), and histological alterations (in the liver
and gills). Although other xenobiotics can induce similar changes, cyanotoxins could be the most likely cause of the observed alterations in C. gibelio tissues. The present study demonstrates the need to monitor this important wetland of international significance, since the living organisms in Lake Ludaš are showing signs of environmental stress suggesting that the preservation and natural balance of this ecosystem could be in danger.

AB  - Cyanobacteria are present in many aquatic ecosystems in Serbia. Lake Ludoš, a wetland area of international significance and an important habitat for waterbirds, has become the subject of intense research interest because of practically continuous blooming of cyanobacteria. Analyses of water samples indicated a deterioration of ecological condition and water quality, and the presence of toxin-producing cyanobacteria (the most abundant Limnothrix redekei, Pseudanabaena limnetica, Planktothrix agardhii and Microcystis spp.). Furthermore, microcystins were detected in plants and animals from the lake: in macrophyte rhizomes (Phragmites communis, Typha latifolia and Nymphaea elegans), and in the muscle, intestines, kidneys, gonads and gills of fish (Carassius gibelio). Moreover, histopathological deleterious effects (liver, kidney, gills and intestines) and DNA damage (liver and gills) were observed in fish. A potential treatment for the reduction of cyanobacterial populations employing hydrogen peroxide was tested during this study. The treatment was not effective in laboratory tests although further in-lake trials are needed to make final conclusions about the applicability of the method. Based on our observations of the cyanobacterial populations and cyanotoxins in the water, as well as other aquatic organisms and, a survey of historical data on Lake Ludoš, it can be concluded that the lake is continuously in a poor ecological state. Conservation of the lake in order to protect the waterbirds (without urgent control of eutrophication) actually endangers them and the rest of the biota in this wetland habitat, and possibly other ecosystems. Thus, urgent measures for restoration are required, so that the preservation of this Ramsar site would be meaningful.
