AB  - Environmental DNA (eDNA) metabarcoding is an effective method for studying fish communities but allows only an estimation of relative species abundance (density/biomass). Here, we combine metabarcoding with an estimation of the total abundance of eDNA amplified by our universal marker (teleo) using a quantitative (q)PCR approach to infer the absolute abundance of fish species. We carried out a 2850-km eDNA survey within the Danube catchment using a spatial integrative sampling protocol coupled with traditional electrofishing for fish biomass and density estimation. Total fish eDNA concentrations and total fish abundance were highly correlated. The correlation between eDNA concentrations per taxon and absolute specific abundance was of comparable strength when all sites were pooled and remained significant when the sites were considered separately. Furthermore, a nonlinear mixed model showed that species richness was underestimated when the amount of teleo-DNA extracted from a sample was below a threshold of 0.65 × 106 copies of eDNA. This result, combined with the decrease in teleo-DNA concentration by several orders of magnitude with river size, highlights the need to increase sampling effort in large rivers. Our results provide a comprehensive description of longitudinal changes in fish communities and underline our combined metabarcoding/qPCR approach for biomonitoring and bioassessment surveys when a rough estimate of absolute species abundance is sufficient.

AB  - Sturgeon populations are declining worldwide and are the target of extensive conservation efforts. Addressed in several pieces of legislation, sturgeons have received considerable attention as flagship or umbrella species. Despite the need for a better understanding of the distribution and population status, the use of traditional sampling methods failed in the past, thereby hampering reliable assessments, a prerequisite for conservation. Here, we describe the development and application of an environmental DNA (eDNA) metabarcoding approach for detecting rare sturgeons in large rivers. Exemplarily, we developed a reference database for five native Danube sturgeons ( Acipenser stellatus , Acipenser gueldenstaedtii , Acipenser ruthenus, Acipenser nudiventris, and Huso huso ) and two non-native species ( Acipenser baerii and Acipenser transmontanus ), assessed these ex situ, and used eDNA as a detection tool along the entire length of the Danube (Europe, ~ 2850 km) and major tributaries. In ex situ analyses, all assays yielded positive amplifications for the assessed sturgeon species. In the Danube, the presence of A. ruthenus was confirmed at 14 of 29 sites (48.3%), and in 2 of 18 tributary sites (11.1%), providing the first comprehensive large-scale biogeographical snapshot of this species. Relative number of reads assigned to A. ruthenus varied between 0 and 2.5%, with sites registering positive detections being clustered in 3 sections of the Danube. Our findings enabled us to confirm the advantages of eDNA monitoring over traditional sampling methods for comprehensive whole-river snapshot studies of sturgeons conducted on a large geographical scale, and therefore we consider it to be a promising approach for application in conservation measures, fisheries management, scientific studies, and adaptive management plans for sturgeons on a global scale.

AB  - The giant European catfish, Silurus glanis (total length = 200 cm; total weight ≈ 80 kg) was caught downstream of Iron Gate II hydropower dam (Danube River, 863 rkm) and tagged with an ultrasonic transmitter (V16TP; Vemco Ltd.) equipped with depth and temperature sensors. Changes in catfish diving behavior and temperature exposure were monitored over a period of roughly 2 years. Transmitter detections were recorded by nine autonomous receivers (VR2W, installed in 2015 between Serbia and Romania, as well as near Romanian shiplock and upstream Romanian turbines). The first signals were recorded on April 28, 2015 and the last on February 13, 2017. Altogether 59,355 and 59,175 detections of the catfish depth and water temperature were recorded, respectively. The greatest number of signals were recorded by the two receivers closest to the location where the catfish was caught, 72.3% and 27.1%, while only 0.6% of signals were recorded by other receivers. The mean catfish depth was 8.4 m, while minimum and maximum depths were 1.2 and 16.2 m. Results obtained showed that this catfish exhibited high site fidelity, while changes in depth at certain periods are possibly related to its search for prey and upstream migration during the spawning period. Hydropower dam and shiplock were obstacles on its migration upstream and telemetry studies could ensure habitat requirements and meet the development of restoration and conservation strategies for the fish resources in the future.

AB  - Vimba bream (Vimba vimba) individuals were collected from the Danube River near Belgrade, from May 2016 to May 2017. Samples of muscle and liver tissue were analyzed for concentrations of 25 elements (macro-, micro-, and toxic elements) using inductively coupled plasma optical emission spectrometry (ICP-OES). For both tissues, the highest concentrations of most elements were observed in late spring/early summer (months of May and June). Majority of statistically significant correlations between elements were positive in both tissues. Contributions of Ca, K, and Mg to human diet were in a similar range. The lowest contribution of all macroelements was observed for Na, while the contribution of Se was well above the recommended dietary allowance for this element. Levels of detected elements were well below MAC values prescribed by national and international regulations. The highest value of Hg liver/muscle index (>1) was observed in August, which could indicate a higher contamination of the sampling location in that month. Se:Hg molar ratio never drops below 1, which could indicate that Hg toxicity is prevented. THQ values showed little variation thought the year and were well below the threshold of 1, with the exception of THQ for Al in May (0.92). This element also strongly affects the hazard index.

AB  - This study was conducted on the Danube River locality Višnjica, exposed to the discharge of the largest wastewater collector in Serbia's capital, Belgrade. Concentrations of metals and metalloids (Al, Fe, Cr, As, Sr, Mn, Cd, Zn, Mo, Cu, Li, Ni, B, Co, Pb, and Ba) and histopathological alterations were investigated in different tissues of common bream during one representative month of each season in 2014. This is the first study in which these two biomarkers were assessed parallelly in common bream. The highest concentrations of examined elements were noticed in gills and the lowest in muscle. Statistically significant differences in element concentrations between different seasons were noticed only in gills for Al, Cu, and Fe. Concentrations of As and Pb in fish muscle were below the maximum acceptable concentrations (MAC). The histopathological index (HI) of the liver showed higher values in comparison to the HI of the gills. Histopathological index of the gills had a significantly higher score in November in comparison to August. The liver HI had the highest score in April, and the lowest in August, while the total histopathological index had the highest score in November, and the lowest in August, both without significant differences between the months. This study endorses gills and liver as reliable organs for studying accumulation and histopathology as biomarkers of environmental changes. A faster reaction of the gills was confirmed since seasonal variations of both biomarkers were observed in this organ. Common bream proved as a good indicator of the state of organisms in polluted environments.

Histopathological index of the gills had a significantly higher score in November in comparison to August. The liver HI had the highest score in April, and the lowest in August, while the total histopathological index had the highest score in November, and the lowest in August, both without significant differences between the months. This study endorses gills and liver as reliable organs for studying accumulation and histopathology as biomarkers of environmental changes. A faster reaction of the gills was confirmed since seasonal variations of both biomarkers were observed in this organ. Common bream proved as a good indicator of the state of organisms in polluted environments.",

AB  - Vimba bream individuals (n = 157), obtained from commercial catches in 2016 and 2017 near Belgrade. were analysed to obtain information on growth and condition of this species. The total body length of sampled fish ranged from 248 to 440 mm, while the body weight ranged from 139 to 889 g. Five age classes (from 4+ to 8+) were present in the sample, with predominance of individuals aged 6+. Back-calculated annual length growth was the highest in the first year of life. The total body length defined according to the parameters of the von Bertalanffy growth curve could be calculated at any given time t using 75.07 x (1-e(-0.06x(t+1.73))), and the length-weight relationship - using LogW = 0.010 + 3.02 x logTL. The asymptotic standard body length was SL infinity = 63.86 cm and the phi-prime growth performance index was phi'= 2.53. The highest mean values of Fulton's condition factor were observed in spring of 2016, followed by spring of 2017, and in individuals aged 7+. The seasonal and age-related differences in condition were statistically significant. The lack of data, the degree of endangerment in some European countries, the status of important species for the river continuity restoration and commercial exploitation of this species, emphasise the need for future research.

AB  - Parasitic species of freshwater fishes represent a large group of organisms including either adults or larval stages. Macroparasites - Nematode (round worms) infect many different species of aquacultured and wild fish. Adult forms are typically found in fish digestive tract.
The present work covers the investigation of nematode parasites of fish from the Belgrade section of the Danube River. During ichthyoparasitological study have been collected and examined 22 freshwater fish species from families Cyprinidae (14), Esocidae (1), Percidae (4), Centrarchidae (1), Gadidae (1) and Siluridae (1). A total of 802 fish specimens have been examined and 54.86% were infected. In intestine of 12 infected fish species have been found 9 species of Nematode parasites - Hysterothylacium bidentatum (Linstow, 1899), Contracaecum siniperca (Dogiel & Achmerov, 1946), Contracaecum sp.  juvenile (Railliet & Henry, 1912), Cammalanus  lacustris (Zoega, 1776), Cammalanus truncatus (Rudolphi, 1814), Camallanus sp. juvenile  (Railliet & Henry, 1915), Philometra rischta (Skrjabin, 1923), Rhabdochona denudata  (Dujardin, 1845) and  Rhabdochona hellichi (Šrámek, 1901). During investigation, species Philometra rischta has been marked off (“heat parasite”), infesting a four fish species (Blicca bjoerkna, Leuciscus idus, Perca fluviatilis, Sander lucioperca) with prevalence of infestation 1-17. Fish species with great number of nematode parasite in intestine was Lota lota (four), while other were infected with one or two parasites.

AB  - Water quality in the Danube River Basin is largely influenced by the inputs of pollutants - particularly
excessive nutrients, organic material, and hazardous substances, which affects the whole ecosystem
at various levels. The major goal of this study was to evaluate the level of genotoxic potential at the
site at Danube River, Novi Banovci, which is under significant anthropogenic pressure of untreated
municipal and industrial waste waters.
DNA damage in situ was assessed in 5 specimens of white bream (Blicca bjoerkna) erythrocytes, liver
and gills cells with comet assay and in erythrocytes with micronucleus test. Additionally, genotoxicity
of native water samples collected from the site and upstream and downstream of the site was
evaluated by the comet assay on HepG2 cells. Microscopic images of comets were scored using Comet
IV Computer Software (Perceptive Instruments, UK) and tail intensity was chosen as parameters to
assess the DNA damage.
Comet assay on white bream showed that gills were the most affected tissue, while liver showed the
smallest values. Micronuclei frequency was low in general, with mean of 1 micronuclei in 5000 scored
erythrocytes, with no significant correlation to the values of comet assay in erythrocytes. Comet assay
on HepG2 cells showed significant difference between values of negative control samples and samples
of water from effluent site and downstream of wastewater discharge. There was no significant
difference between negative control and upstream samples of water.
Our results showed that great impact of municipal and industrial wastewaters on the river ecosystem.
The application of in vitro and in situ tests gives a better insight into genotoxic effects. More
importantly, because Serbia still doesn’t have waste water treatme nt plants, this kind of research
points out the imperative for implementation of this facilities.

AB  - Fish erythrocytes released from erythropoietic sites are immature. During circulation, they increase their own surface, while the cell body and nuclei begin to become more elliptical and less spherical during maturation. The relative abundance of different developmental stages represents an erythron profile which could be a more sensitive indicator of contamination than classic hematological indices. In this study, we analyzed blood smears of the common nase (Chondrostoma nasus) and vimba bream (Vimba vimba) with the main goal to identify the determinants of the developmental stage of erythrocytes. Based on parameters developmental stages, erythrocytes are categorized into immature, intermediate or mature. In this investigation we have used four classification methods: the Two Step Cluster analysis, the K-Means Cluster analysis, and Neural Networks–Multilayer Perceptron and an Ordinal Regression model. Our findings clearly justify that Multilayers Perceptron and OLR models are appropriate to classify the developmental stage of fish erythrocytes in both species.

AB  - This chapter examines the relationship between knowledge and Environmental Citizenship. Knowledge has been attributed to have an essential role in influencing pro-environmental behaviour and as such in the development of Environmental Citizenship. We argue that the ‘right’ kind of environmental knowledge is a necessary precondition for pro-environmental behaviour and thus for Environmental Citizenship. In this chapter, we focus on knowledge, but we also emphasise that efforts on fostering knowledge alone in education for Environmental Citizenship, without links to real life, competencies and values, are insufficient for the sake of a sustainable world. We explore which knowledge is needed in order to cultivate the coherent and adequate skills, values, attitudes and competences that we think an Environmental Citizen should have. We identify three different types of knowledge: (i) environmental systems knowledge, (ii) action-related knowledge and (iii) effectiveness knowledge. Finally, we suggest a process of co-production of new knowledge between experts and key citizens as central to the idea of a participatory approach towards developing Environmental Citizenship.

AB  - The Danube River basin represents a hotspot for the European freshwater diversity. The Danube in Serbia is characterized by a significant level of fish diversity, as well as by economically important fish resources. However, the Danube fish fauna is facing a number of adverse anthropogenic impacts, such as unsustainable fishery, habitat loss and fragmentation, water pollution and non-native species invasions. In this chapter, the major adverse impacts on the Danube fish communities in Serbia are presented, and the critical management measures are discussed, such as those related to supportive stocking and other conservation efforts. In order to ensure adequate protection and sustainable management of fish resources in the Danube in Serbia, it will be critical to introduce effective monitoring system, to establish and enforce adequate management measures, and to intensify research efforts on critical issues related to fish management and conservation.

AB  - This study was conducted on individuals of European perch from six reservoirs in Serbia with different properties, used for different purposes, and situated at different altitudes. Samples of muscle, gills, and liver, as well as water samples, were used for analysis of elemental accumulation. Histopathological (HP) analysis of gills and liver, and Fulton's condition factor (CF) were used as biomarkers. Analysis of Ag, Al, As, B, Ba, Ca, Cd, Co, Cr, Cu, Fe, Hg, K, Li, Mg, Mn, Mo, Na, Ni, P, Pb, S, Se, Si, Sr, and Zn was conducted by inductively-coupled plasma optical emission spectrometry (ICP-OES), and accordingly, metal pollution index and bioaccumulation factor (BAF) were calculated. Elemental accumulation varied considerably both among tissues and reservoirs. Reservoirs located on large low-altitude rivers were the most heavily polluted with metals (Međuvršje, on the Zapadna Morava River, and Lake Sava, on the Sava River). Of three tissues analyzed, the gills were most affected by pollution. The levels of Hg in muscle decreased with an increase in reservoir altitude. Specimens sampled from the highest altitude reservoir were the least affected by HP alterations; however, HP differences between the reservoirs were not statistically significant, and the severity of HP changes was generally low. No significant correlations between the elemental accumulation or HP indices with CF were observed.

AB  - Concentrations of As, Cd, Cr, Cu, Hg, Pb, and Zn in sediment samples and muscle tissue of the European perch were analyzed using inductively-coupled plasma optical emission spectrometry (ICP-OES), with the aim to assess the potential ecological (RI) and human health risk, and the degree of contamination (Cd) of three types of reservoirs in Serbia, based on their purpose: electricity generation (Vlasina, Perućac, Zaovine, and Međuvršje), drinking water supply (Garaši), and recreation (Lake Sava). The concentrations of the studied elements were higher in sediments than in fish. However, the levels of Cd in fish caught in Vlasina, Zaovine, and Međuvršje, Hg in Perućac and Garaši, and Pb in Lake Sava exceeded the maximum allowed concentrations. The pollution load index (PLI) indicated that sediments in all six reservoirs were contaminated, but Cd was low; a moderate contamination with Cd was observed in Vlasina, Perućac, and Zaovine, Cr in Zaovine and Međuvršje, and Cu in Međuvršje. A low RI was recorded for all studied reservoirs. Cd was found to be the primary contamination and ecological risk factor. Total target hazard quotient (THQ) and target carcinogenic risk factor (TR) were higher for fishers operating in these reservoirs than for the general population. Higher values of PLI, Cd, RI, and TR were observed in electricity generation reservoirs. Results indicated that this type of reservoirs suffer from higher anthropogenic pressure and/or have a worse pollution management policy compared with other types of reservoirs included in this study, especially the drinking water supply reservoir.

AB  - Due to the increasing industrialization, metals are discharged into all spheres of the environment, in particular, in river courses, which leads to the need for constant monitoring. Metals do not degrade into harmless end products; they are very persistent and have high potential for accumulation in biota. Metals in the fish body are accumulated in different amounts in the tissue specific matter. In relation to the biotic conditions and fish metabolism, the load of food, or the stage of the reproductive cycle, the seasonal variation of metal levels can be expected. Because of that, the objective of our present study was to analyze 15 metals and metalloids in liver, gills, muscle, and gonads of European chub (Squalius cephalus) throughout the 4 seasons, autumn, winter, spring, and summer. The specimens were collected from two rivers, Pestan and Beljanica at the Kolubara basin, and their concentrations were determined with inductively coupled plasma optical emission spectrometry (ICP-OES). Specimens from both rivers have shown similarities in metal accumulation like the highest accumulation of majority of elements in gills, lowest accumulation of majority of elements in muscle (except for Hg), and higher accumulation of some elements in summer (Cu, Fe, Zn). In addition, Cu and Fe showed affinity for liver, while Ba, Cr, Sr, and Zn were specific for gills. Also, Al, B, Fe, Ni, and Pb did not show significant differences in concentrations among different seasons in all investigated tissues.

abstract = "Due to the increasing industrialization, metals are discharged into all spheres of the environment, in particular, in river courses, which leads to the need for constant monitoring. Metals do not degrade into harmless end products; they are very persistent and have high potential for accumulation in biota. Metals in the fish body are accumulated in different amounts in the tissue specific matter. In relation to the biotic conditions and fish metabolism, the load of food, or the stage of the reproductive cycle, the seasonal variation of metal levels can be expected. Because of that, the objective of our present study was to analyze 15 metals and metalloids in liver, gills, muscle, and gonads of European chub (Squalius cephalus) throughout the 4 seasons, autumn, winter, spring, and summer. The specimens were collected from two rivers, Pestan and Beljanica at the Kolubara basin, and their concentrations were determined with inductively coupled plasma optical emission spectrometry (ICP-OES). Specimens from both rivers have shown similarities in metal accumulation like the highest accumulation of majority of elements in gills, lowest accumulation of majority of elements in muscle (except for Hg), and higher accumulation of some elements in summer (Cu, Fe, Zn). In addition, Cu and Fe showed affinity for liver, while Ba, Cr, Sr, and Zn were specific for gills.

AB  - Accumulation of 17 elements in muscle and liver of common nase and vimba bream, caught between February and May 2016 in the Danube River (1173 river kilometer), were assessed by ICP-OES. The principal component analysis grouped muscle and liver samples based on element concentrations (muscle grouped by higher Ba and Sr values, and liver grouped by higher Al, B, Cd, Cr, Cu, Fe, Mn, and Zn values), but no grouping between the two species was observed. Concentrations of Ba, Cu, Fe, and Zn were significantly higher in muscle, and concentrations of Ba, Cd, Cu, and Mn in liver of common nase, while vimba bream had significantly higher concentrations of Cr and Fe in liver. Common nase has a higher affinity for bioaccumulation of Cu, Fe, and Zn in muscle, while vimba bream has a higher affinity for Al, Cd, and Cr in muscle.

AB  - The life‐history traits and population dynamics of the black bullhead Ameiurus melas (Rafinesque) were studied monthly from August 2009 to December 2012 in Lake Sava in Belgrade (Serbia). This period included a mass mortality event in May 2011 and subsequent population recovery during 2012. Available evidence suggests the mass mortality was caused by European catfish virus that only affected the black bullhead. Changes in key life‐history traits and the recovery potential (increase in catch‐per‐unit‐effort, doubling of young‐of‐the‐year to adult ratio, earlier maturation and increased fecundity) following the mass mortality event suggest population resilience typical of a recurring boom‐bust pattern and demonstrate the species’ capacity to recover rapidly and re‐establish following disturbance. Repeated systematic mass removals of both juveniles and adults (using fyke nets) will be required if future fishery management measures aimed at limiting the population size are to be effective.

AB  - The feeding habits and intestinal parasites of Pontic shad (Alosa immaculata Bennet, 1835) from the Danube river were investigated in 2016 and 2017. A total of 180 individuals were collected and examined. The ranges of total and mean length of examined migrants were: 20.3±30.6 to 30.5±36.3 cm for Prahovo locality, and 17.9±26.7 to 27.5±36.7 cm for the Danube Delta, respectively. Parasitic species were identified in 16 fish specimens (18.6%) from Prahovo and 94 fish specimens (100.0%) in the Danube Delta. Representatives of the phylum Nematoda, namely specimens from the Anisakidae family, Contracaecum sp., Contracaecum siniperca Dogiel & Achmerov, 1946 and Contracaecum bidentatum (Linstow, 1899) Skrjabin, 1917 were determined. Identified parasitic fauna shows low diversity, but the intensity and prevalence of infestation are relatively high. With regard to feeding habits, representatives of macrozoobenthos were identified in the intestinal contents, mostly the insect component (Diptera, Ephemeroptera, Plecoptera, Odonata and Planaria). Macrozoobenthos were more present in the intestinal content of Pontic shad captured in Prahovo than in the Danube delta. Also, the intestines of fish specimens from Prahovo contained other structures, such as algae, detritus, sand, and a few terrestrial insects.
Even though the Pontic shad represents a commercially important fish species in the lower section of the Danube, research on it in this area has been performed only sporadically.

AB  - The major objective of this study was to investigate the impact of wastewaters on the level of genotoxicity and the possible reflection of genotoxicity on the genetic variability in chub (Squalius cephalus) collected from the sites under different pollution pressures along the Sava River. To emphasize the impact of wastewaters, this study was carried out in a season with low water discharge. The level of genotoxic potential at the sites was studied by alkaline and Fpg-modified comet assay in fish blood, while RAPD technique was employed on the fish muscle tissue. The variations in the genotoxic potential were observed along the Sava River based on the level of DNA damage in blood of the specimens collected at the selected sites. Clustering of the impacted sites was also observed based on RAPD fingerprints. Comparison of the data obtained in RAPD and the data from the comet assay indicated the possible reflection of genotoxicity on the genetic variability in chub collected from the sites with different pollution pressure. This is a preliminary study which reports the differentiation of the population of chub along the Sava River based on RAPD analysis.

AB  - The major objective of this study was to investigate the impact of wastewaters on the level of genotoxicity and the possible reflection of genotoxicity on the genetic variability in chub (Squalius cephalus) collected from the sites under different pollution pressures along the Sava River. To emphasize the impact of wastewaters, this study was carried out in a season with low water discharge. The level of genotoxic potential at the sites was studied by alkaline and Fpg-modified comet assay in fish blood, while RAPD technique was employed on the fish muscle tissue. The variations in the genotoxic potential were observed along the Sava River based on the level of DNA damage in blood of the specimens collected at the selected sites. Clustering of the impacted sites was also observed based on RAPD fingerprints. Comparison of the data obtained in RAPD and the data from the comet assay indicated the possible reflection of genotoxicity on the genetic variability in chub collected from the sites with different pollution pressure. This is a preliminary study which reports the differentiation of the population of chub along the Sava River based on RAPD analysis.

AB  - The paddlefish (Polyodon spathula) was first introduced to Europe in 1974, mainly due to its potential for rearing in natural polyculture ponds and large temperate reservoirs. The information on the history of paddlefish aquaculture efforts in Europe is scarce, as well as data on current paddlefish aquaculture status and trends. In addition, there is a lack of data on its presence and potential establishment in the wild, while its invasive potential and associated risks and impacts are largely unknown. In order to evaluate its current status in Europe, we conducted a survey among scientists, aquaculture producers and other stakeholders, and reviewed literature and data on the Internet. Based on the results obtained, we discuss the potential and the challenges in European paddlefish aquaculture development, and analyze paddlefish invasive potential and risks associated with its naturalization. Paddlefish aquaculture is well established only regionally in Europe, but offers relatively high potential for further development in pond farms. Nevertheless, future development will require careful planning, especially regarding market development and improved marketing strategies. While paddlefish likely represents a low-risk invader, improved control and reporting on trade and intentional and unintentional releases will be required. Given the lack of knowledge on potential impacts following its introduction, due caution seems highly advisable.

AB  - Chub (Squalius cephalus) specimens were collected in Korenita River seven months after spillover from the waste water of antimony mine tailing pond and compared with chub living in Kruščica reservoir (intended for water supply) and Međuvršje reservoir (influenced by intense emission of industrial, urban and rural wastewater). Concentrations of 15 elements (Al, As, B, Ba, Cd, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Si, Sr, Zn) were determined in muscle, liver and gills of chub by inductively coupled plasma optical spectrometry (ICP-OES) and histopathological alterations in liver and gills were assessed. Chub specimens from Korenita River had higher concentrations of As, Ba and Pb in all three investigated tissues as well as higher total histopathological index values than chub from reservoirs. Specimens from Međuvršje reservoir were characterized by higher values for concentrations of Cu and Si in muscle tissue and higher values for regressive histopathological alterations in gills. Individuals of chub from Kruščica reservoir had the highest concentrations of Fe in liver, Hg in muscle and Sr and Zn in muscle while gills had the lowest value of total histopathological index. The results from the present study showed higher level of histopathological alterations as a result of mine tailing accident. As a result of mixed contamination on the Međuvršje site, histopathological index values of gills were in line with the index value from Korenita River. Increased values for Fe and Sr in chub tissue from Kruščica reservoir could be explained by geological structure of the site which is characterized by magmatic rock rich in Cu, Fe and Ni as well as dominant carbonate sediment complex of marine origin with increased level of Sr.
