AB  - European rivers are obstructed by more than one million barriers that have resulted in excessive loss of river continuity. On the main course of the Danube River there are 83 longitudinal continuity interruptions, out of which 65 dams are used for hydropower (ICPDR 2022a). The Iron Gate Hydropower and Navigation System is one of the largest river engineering projects undertaken in Europe, with the dams mainly built to provide hydropower and flood protection, and to facilitate navigation along the Danube. These infrastructures represent introduced barriers to fish migration. Hence, ensuring passage opportunities for fish at the Iron Gate dams is considered to be of major importance for the conservation of migratory fish populations in the Danube River basin. Restoration of river continuity at these sites would reopen an additional 900 km for migration up to the Gabčikovo dam, providing suitable habitats and spawning grounds along the Danube and its tributaries. Knowledge about fish behavior and movements in the vicinity of these river infrastructures is required to build effective up- and downstream passage facilities to allow the migration of fish species. To gain insight in the approach routes and aggregation areas a refined approach to acoustic telemetry is employed to support migration facilitation.

AB  - River infrastructures, such as hydropower plants Iron Gate I (IG; rkm 943) and II (rkm 863) represent major obstructions to fish migration in the Danube River. Knowledge about fish behaviour and movements in the vicinity of major river structures is required to build effective fish passages to protect migratory fish species, with acoustic telemetry being an useful method for observing such behaviour. From autumn 2019 to the spring 2021, the movement of 185 fish (barbel Barbus barbus, nase Chondrostoma nasus, vimba bream Vimba vimba, asp Leuciscus aspius, Pontic shad Alosa immaculata, and carp Cyprinus carpio) were monitored in the Danube River upstream and downstream of the IG II dam using acoustic telemetry. The movements of tagged fish were recorded by a combination of automatic tracking of fish passing receivers deployed in the river and manual tracking by boat. Of the 101 fish released downstream of IG II, 48% moved upstream from their release site and were detected close to IG II. The remaining 84 tagged fish were released in the reservoir between IG I and II, with 49% of fish moving further upstream in the reservoir and 18% reaching IG I, while 48% of the tagged fish moved in a downstream direction and were recorded below IG II. No fish released downstream of IG II were detected in the reservoir between two dams, which indicates that the ship locks on either side of the river do not represent viable routes for upstream migration around IG II. There was also no clear pattern in which side of the river tagged fish preferred to move along. To conserve migratory fish species, dam management strategies that take into account the behaviour of fish around such structures is necessary. Acoustic telemetry can be used to inform and guide towards construction of the safe fish passage or adapt structures to improve the movement and fish migration.

AB  - In this study a battery of bioassays, both in vivo (metals and metalloids concentrations, erythrocyte morphometry, comet assay, micronucleus assay, and histopathological analyses) on vimba bream Vimba vimba (L., 1758) and white bream Blicca bjoerkna (L., 1758), and in vitro (treatment of HepG2 cells with native water samples) was applied to assess the harmful potential of untreated wastewater. Faecal indicator bacteria were quantified to assess the microbiological water quality. Vimba bream had significantly higher Fe concentrations in both liver and muscle, while white bream had higher Ca and Cu concentrations in liver. Vimba bream had a significantly higher level of DNA damage in both liver and blood cells, in comparison to white bream. Low levels of micronucleus and nuclear abnormalities were observed in both species. Erythrocytes morphometry did not show significant interspecific differences. Histopathological analyses revealed a similar response of the studied species, with a significantly higher presence of ceroid pigments in the liver of vimba bream. Treatment of HepG2 cells revealed the high genotoxic potential of water downstream of the discharge point. The results of this study clearly demonstrate the importance of effect-based monitoring, in order to enforce more efficient management of natural resources and implementation of wastewater treatment systems.

AB  - One of the most severe threats to the Danube River course through Serbia is the direct discharge of untreated wastewater. In biomonitoring studies, faecal indicator bacteria are used to reveal the presence of untreated communal wastewater, while biomarker response in indigenous biota serves as a useful indicator of their harmful potential. The objective of this study was to estimate the genotoxic potential of untreated communal wastewater at two sites on the Danube River, Višnjica (Belgrade) and Novi Banovci, by using in situ approach in white bream (Blicca bjoerkna L.). A comet assay was selected to measure DNA damage in erythrocytes, liver, and gill cells, while the micronucleus test was applied to measure chromosomal aberrations in erythrocytes.
Additionally, the accumulation of 22 elements in fish liver and muscle was analysed by ICP-OES meth- od. Simultaneous detection of total coliforms and E.coli in water was performed by enzyme-based Colilert-18 test (IDEXX). Comet assay revealed the highest level of DNA damage in gills at the site Novi Banovci, and in blood at the site Višnjica. The overall frequency of micronucleus at both sites was low. At both localities, the majority of analysed elements showed higher levels in the liver in comparison to muscle. Microbiological indicators confirmed the poor water quality, since at both sites water was categorised as critically to strongly polluted. The results of this study highlighted the importance of in situ biomonitoring approach and the need for more effective management of natural resources and implementation of wastewater treatment systems.

AB  - The present study was carried out to investigate the differences in some enzymatic components of liver in vimba bream (Vimba vimba) and common nase (Chondrostoma nasus). For this purpose, 33 healthy vimba bream and 20 common nase were collected from commercial catches on the Danube River, near Belgrade (1172-1173 rkm), in 2016. The blood samples were taken and after separation of serum, the values of Aspartate aminotransferase (AST) and Alanine aminotransferase (ALT) enzymes activities were measured. Based on obtained results, the values of AST and ALT enzymes activities were slightly lower in the common nase compared to vimba bream, which is a possible indicator of better health and physiological status, and greater resistance to environmental pollutants present in the habitat. This difference was, however, not statistically confirmed. Considering that the selected fish were captured by the same method, having a similar ecology, living in similar habitats and under similar ecotoxicological conditions, it is not surprising that the differences in the activity of the measured liver enzymes were minimal. Since common nase is important bioindicator species, similar results could indicate that vimba bream could be considered as replacement species for this types of research, if future studies indicate the decline or endangerment of common nase populations.

AB  - Pontic shad (Alosa immaculata) is an anadromous species that lives in the Black Sea and Sea of Azov
and migrates into the Danube, Don and other rivers to spawn. It is still economically important fish
species in the Danube River. As the North-Western part of the Black Sea is heavily polluted
investigation was performed to determine heavy metal and element accumulation in muscle tissue of
Pontic shad as well as to record the level of histopathological changes. Pontic shad specimens were
caught on 863 river kilometer of the Danube and the first investigation was performed during 2007
and repeated one decade later in the period 2017-2019.
Element analysis was performed by inductively-coupled plasma – optic emission spectroscopy (ICPOES).
In both sampling periods, only concentrations of arsenic (As), copper (Cu), iron (Fe),
magnesium (Mg), strontium (Sr), and zinc (Zn) were above detection limit. Higher concentrations of
As, Cu, and Zn were detected in 2007, while higher concentrations of Fe, Mg, and Sr were measured
in 2019. Differences in concentrations of these elements, between sampling periods, were
statistically significant.
The gills of sampled fish were assessed using histopathology as a marker of general fish health state,
using semi-quantitative scoring system. The histopathological results revealed different pattern of
histopathological alterations in the gills of fish sampled during two distinct time periods. According to
the method used, there were no difference in total gill histopathological index, but alterations were
specific for fish sampled at two time points. Hyperemia and hyperplasia of respiratory epithelium
dominated in fish sampled at the year 2007, while necrosis of branchial tissue prevailed in fish
sampled a decade later.

abstract = "Pontic shad (Alosa immaculata) is an anadromous species that lives in the Black Sea and Sea of Azov
and migrates into the Danube, Don and other rivers to spawn. It is still economically important fish
species in the Danube River. As the North-Western part of the Black Sea is heavily polluted
investigation was performed to determine heavy metal and element accumulation in muscle tissue of
Pontic shad as well as to record the level of histopathological changes. Pontic shad specimens were
caught on 863 river kilometer of the Danube and the first investigation was performed during 2007
and repeated one decade later in the period 2017-2019.
Element analysis was performed by inductively-coupled plasma – optic emission spectroscopy (ICPOES).
In both sampling periods, only concentrations of arsenic (As), copper (Cu), iron (Fe),
magnesium (Mg), strontium (Sr), and zinc (Zn) were above detection limit. Higher concentrations of

AB  - In this study, the movements and behaviour of Wels catfish (Silurus glanis, Linnaeus, 1758) were
monitored during the different seasons when the water level in the river changed significantly. Wels
catfish was caught on the Danube River, rkm 863, and tagged with an ultrasonic transmitter.
Deployed Vemco receivers recorded detections of spatial movement between years 2015 and 2017.
Our telemetry data found relatively short movements within a maximum range (~12km), but as a
territorial species most of the time it was recorded by the two receivers, close to the Iron Gate dam
and location where it was caught. Circadian rhythm showed that in the summer period, nocturnal
activity is evident while during winter Wels catfish stayed most of the time at the same depth under
the water surface. Wels catfish changed depths during the autumn and spring when more activity
was recorded. The last signal received was during the winter 2017, which was period with the low
temperatures and ice cover on the Danube River. This research shows the value and importance of
installing coded acoustic transmitters in fish and monitoring their movement using a series of
autonomous receivers deployed in the Danube River. Research by telemetry can be used to better
understand fish behaviour and movements and to help improve large river management measures.

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 nonnative
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.

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 dam’s construction without fish passes had a major impact, obstructing migratory fish populations from moving between different parts of the river systems and utilizing their key habitats. Fish species and fish populations are depending on long migrations are most seriously affected by river fragmentation. Building well-functioning fish passage systems for migratory fish species at Iron Gate I (rkm 943) and Iron Gate II (rkm 863), is crucial for strengthening and re-establishing Danube’s River migratory fish populations. Between March and May 2021, 112 fish specimens were captured downstream Iron Gate II dam. All the fish was previously tagged with 69 KHz ultrasonic transmitters and released upstream Iron Gate II dam reservoir (53 fish) and downstream Iron Gate II dam (59 fish). Some of the acoustic transmitters are equipped with depth sensors, which provide information of water depths used by fish. Fish movements were recorded by a network of 18 ultrasonic automatic Vemco VR2w receivers (10 downstream the Iron Gate II dam and Gogosu branch, 6 in the IG II lake and 2 receivers at the Iron Gate I dam) with a 15 month battery life, positioned in Danube River. Downloading and interpreting recorded data by these receivers will be an important starting point for "We Pass 2" project that will begin in fall of 2021, when will be realized high resolution recordings of 3D fish movements, for finding the best technical solution for their passing upstream or downstream of dams.

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 treatment plants, this kind of research 
points out the imperative for implementation of this facilities.

AB  - This study was conducted on the Danube River locality Visnjica, 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.

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  - 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  - Wels catfish (Silurus glanis, Linnaeus, 1758) is one of the most targeted species for recreational and commercial fishing in the Danube River, even though studies of behavior and movement patterns of Wels catfish in the Danube are rare. Wels catfish was caught downstream of Iron Gate II hydropower dam and tagged with an ultrasonic transmitter (Vemco Ltd, V16TP). Nine autonomous receivers (Vemco Ltd, VR 2W) recorded detections of spatial movement downstream of Iron Gate II dam between Serbia and Romania for almost two years, between the years 2015 and 2017. Our telemetry data found that Wels catfish exhibit relatively short movements within a maximum range (≈ 12 km), but as a territorial species most of the time it was recorded by the two receivers, close to the Iron Gate dam and location where it was caught. The longest displacement from the preferable place under Iron Gate II dam was migration to Romanian ship lock and turbines located in the right arm of the Danube River. Location under the river dam is already recognized as a place of aggregation of the fish and thus preference of predatory catfish is strongly connected with food availability. Our data revealed that dam and ship lock blocked further migration of this fish. The last signal received was during the winter 2017, which was a period with extremely low temperature and ice cover on the Danube River. Considering the fact that the ice displaced whole receiver deployment downstream the dam, we might conclude that the tagged catfish disappeared because of ice movement during the winter season. Results can be used for management ensuring habitat requirements and developing of restoration and conservation strategies.

AB  - The giant European catfish, Silurus glanis (total length = 200 cm; total weight approximate to 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  - 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  - 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, PeruEac, Zaovine, and Meduvrkie), drinking water supply (GarOi), 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 Meduvrkie, Hg in Perueac and GarOi, 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, Peru&c, and Zaovine, Cr in Zaovine and Meduvfgje, and Cu in Meduvitje. 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 (THOJ 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  - 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 (Meduvrgje, 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  - 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  - During the last decades in the freshwater system in Serbia 27 allochthonous fish species appeared, and they can be divided into two groups. In the first group are representatives of fish fauna which are originally from Asia and they are intentionally introduced into open waters and aquaculture in Serbia, while the second group represent the migrants spreading their range from the Black Sea into freshwater systems. Some of these species already have established populations. Representatives of marine fauna that inhabit fresh-water systems in Serbia are: Syngnathus abaster, Neogobius fluviatilis, Babka gymnotra-chelus, Ponticola kessleri, Neogobius melanostomus, Proterorhinus (marmoratus) semi-lunaris, Gasterosteus aculeatus, Knipowitschia caucasica, Morone morone x Morone saxatilis. Gobiids extended their geographical distribution outside their native range and expanded their area of distribution in throughout whole Danube River Basin, while for the other specimens there are no literature data about established populations.
