AB  - Pikeperch of age classes 3+ and 4+ were collected from the Garaši reservoir (Serbia)
to analyze their bioindicator potential and compare their possible differences. Concentrations of
26 elements were determined in gills, muscles, and liver by inductively-coupled plasma optical
emission spectrometry (ICP-OES) and of 17 organochlorine pesticides (OCPs), and six polychlorinated
biphenyls (PCBs) in muscle by gas chromatography with mass spectrometric detection (GC-MS).
Histopathological changes in the liver and gills were analyzed as biomarkers of general fish health.
Only the concentrations of Cd, Na, and P in the muscles differed significantly. The OCPs and
PCBs concentrations were below the detection limits, so fish meat consumption does not pose a risk
concerning these substances. Hg and Cd exceeded the maximum allowed concentrations in some
4+ individuals, probably due to biomagnification. Gills were the most affected by metal exposure in
both age classes. Histopathological changes and indices were minor and did not differ significantly
between age classes, suggesting that pollution did not affect the morphology and structure of gills and
liver. There were no significant correlations between elemental accumulation and fish condition or
between histopathological scores. Therefore, both age classes can be used as bioindicators of pollution.

AB  - Invasive alien fish species represent one of the greatest threats to the
biodiversity and ecological status of freshwater ecosystems. Within their
management, their application as bioindicators of pollution in monitoring
programs should be considered. The aim of this study was to examine the
use of black bullhead Ameiurus melas (Rafinesque, 1820), invasive alien fish
in Serbia, as a bioindicator of water genotoxicity by alkaline comet assay.
Sampling was performed from June to September 2021 on Markovačko
Lake, which is exposed to diffuse pollution from the application of pesticides
on the surrounding agricultural land. Monitoring also included the
assessment of water quality by basic physical and chemical parameters, as
well as microbiological indicators of faecal pollution. Alkaline comet assay
was performed on fish erythrocytes, on ten specimens per month. The study
also included ten control fish from the recirculating aquaculture system
(RAS), which were transferred from Markovačko Lake for breeding, and
treatment of their erythrocytes with H2O2 as a positive control. Scoring of
comets was performed by CometScore 2.0 software. The lowest level of
DNA damage was recorded in the control group and the highest in the
positive control group. August was the month with the lowest level of DNA
damage, and September with the highest. Statistically significant
differences were found between all groups indicating a high sensitivity of
the alkaline comet assay to discriminate fine differences in the genotoxic
potential of water. Knowing that black bullhead is highly abundant in
stagnant waters and relatively easy to sample, this study draws additional
attention to its use as a bioindicator of genotoxicity.

The highest concentrations of Cu in liver as well as Ba, Ca, Fe, Mn, Na, P, and Sr in gills were detected in all fish species, while the lowest concentrations of Cu, Fe, Mn, Na, and Zn were detected in muscle. Pikeperch had significantly lower concentrations of Ba in all tissues compared to the other species, as well as Fe, P, and Sr in muscle, K, Mg, Mn, Sr, and Zn in gills, and Fe in gonads. European chub had significantly higher concentrations of Ca, Cu, and Zn in muscle, Cu in liver, and Cr and Cu in gonads compared to Cactus roach and pikeperch. Cd concentration in one individual of Cactus roach exceeded the maximum allowed concentration. The muscle was exposed to the lowest pressure of metal pollution in all species, and European chub accumulated more metals compared to the other species. There is no significant health risk due to consumption of investigated species. A major hazard index (HI) contributor in all species was Hg. According to the target carcinogenic risk factor (TR), target hazard quotient (THQ), and HI, men are under lower health risk compared to the women. The TR and THQ for As, Cr, Cu, Fe, Mn, Ni, and Zn as well as HI values were higher for European chub compared to the other species. On the other hand, THQ for Hg was highest for pikeperch.

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  - 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.

abstract = "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.

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  - 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  - Izgradnjom brana se prekida longitudinalni kontinuitet reke čime se značajno utiče na kvalitativan i kvantitativan sastav ihtiofaune u novonastalim akumulacijama, kao i na sektoru reke nizvodno od brane. Izrazito negativan efekat se ispoljava na populacijama migratornih vrsta riba, gde su posebno ugrožene anadromne vrste koje migriraju iz mora u reke radi mresta. Izgradnja brana, Đerdap I na 943 kilometru Dunava 1970. godine i Đerdap II na 863 kilometru Dunava 1984. godine, je negativno uticala na brojnost populacija vrsta riba iz porodica Acipenseridae (jesetri) i Clupeidae (haringi), koje migriraju iz Crnog mora u Dunav radi mresta. Nakon izgradnje brane Đerdap II u srpskom delu Dunava, mrest ovih vrsta je moguć samo na 17,4 kilometara toka nizvodno od brane do granice sa Bugarskom. Kao posledica pregrađivanja Dunava u komercijalnim izlovima ribara se umesto ekonomski veoma cenjenih jesetarskih vrsta, kao što su moruna (Huso huso), ruska jesetra (Acipenser gueldenstaedtii) i pastruga (Acipenser stellatus), javljaju ekonomski manje cenjene alohtone vrste riba kao što su tolstolobik beli (Hypophthalmichthys molitrix), tolstolobik sivi (Hypophthalmichthys nobilis), beli amur (Ctenopharyngodon idella) i babuška (Carassius gibelio). Iako potamodromna vrsta, koja migrira samo u okviru reka, kečiga (Acipenser ruthenus) takođe pokazuje smanjenje brojnosti populacija posle izgradnje brana, pri čemu su u ulovima zastupljene mlađe uzrasne klase u odnosu na period pre izgradnje brana. Uspor brzine toka Dunava u akumulacijama je omogućio širenje alohtonih vrsta riba. Od ranih sedamdesetih, zabeleženo je širenje predstavnika familije glavoča (Gobiidae ) duž Dunava, uglavnom zahvaljujući izgradnji brana i kanala. Danas su sve jesetarske vrste, osim kečige, označene na Crvenoj listi IUCN kao kritično ugrožene, dok su dve vrste haringi (Alosa immaculata i Alosa tanaica) zaštićene u Srbiji. U cilju zaštite biodiverziteta ihtiofaune na ovom području neophodno je započeti studije za izgradnju ribljih staza na pomenutim branama, što može voditi ka oporavku populacija jesetarskih i drugih migratornih vrsta u ovom delu Dunava, kao i obnavljanju njihovog komercijalnog izlova.

AB  - The relationship between the Lower Danube River level and Romanian annual catches of Pontic shad (Alosa immaculata, Bennett 1835) were analyzed. For analysis of long term data on the Danube River water level and Pontic shad catch, combinations of different methods were applied using statistical programs, SPSS 13.0 and MATLAB 6. Periodograms, containing cyclic patterns, were obtained using Fourier analysis. Significant oscillations were determined with Fisher-Whittle’s tests and residuals were calculated after subtracting these significant oscillations from the original signals. Autoregressive moving average (ARMA) models of residuals were finally applied. Results indicated that river water levels, and especially those in May, greatly explained the fluctuations of Pontic shad catch. Annual landings varied greatly and appeared to be cyclic. Varying river flow was considered to be one of the most important factors that cause fluctuations in the size of populations. Forecast indicates gradual increase of the catch in the next decade, followed by a decrease in other decades. Estimated as a vulnerable species of fish by the IUCN, development of the forecasting model of the future catch oscillations could be very helpful to regulate fishing efforts towards the sustainable use of stocks and species conservation.

AB  - Some recent data show that five gobiid species have spread outside their native range and
expanded their distribution area in Serbia along the rivers Danube, Tisza, Sava, and Velika
Morava. These are: monkey goby Neogobius fluviatilis, racer goby Neogobius
gymnotrachelus, bighead goby Neogobius kessleri, round goby Neogobius melanostomus,
and tubenose goby Proterorhinus semilunaris.
The aim of this study was to compare the efficiency of two different methods for
fish sampling, as well as to assess influence of the diel period on catch of gobiids in the
Serbian stretch of the Danube River. During October 2012 and September 2013, the
sampling was performed by electrofishing and beach seining in four riverside locations of
the Danube River, as follows: at Novi Sad (river km 1257), Belgrade (river km 1173), Tekija
(river km 956), and Prahovo (river km 862), with the water depth being of up to 120 cm. At
each location, the sampling was performed at 17:30, 18:30, 19:30 and 20:30.
A total of 551 gobies were caught. The highest number of specimens (238) was
registered at Tekija, followed by the sites at Belgrade (192) and Prahovo (109), and only 12
specimens caught at Novi Sad. The catch of the round goby and monkey goby was more
efficient by beach seining than by electrofishing, while the catch of the tubenose goby was
more efficient by electrofishing. Both methods had similar efficiency in terms of the catch
of the bighead goby and racer goby. The species diversity and the number of caught
specimens were the highest at 18:30. All five species were recorded at the sites of Belgrade,
Tekija and Prahovo, while only the monkey goby and racer goby were caught at Novi Sad.
The methods used in this study showed good efficiency in catch of gobiids, especially at
dusk. Despite the difficulty in using these methods in certain habitats, we assume that they
could be highly relevant in the regular monitoring of gobiids along the inshore parts of the
rivers.

At each location, the samplings were performed at 17:30, 18:30, 19:30 and 20:30. Totally, 539 gobiids were caught. The highest number of specimens (218) was registered at Tekija, while lower numbers were registered at Belgrade (192) and Prahovo (117), and only 12 specimens were caught at Novi Sad. The catch of the round goby Neogobius melanostomus and monkey goby Neogobius fluviatilis was more efficient by beach seining than by electrofishing, whereas the catch of the tubenose goby Proterorhinus semilunaris was more efficient by electrofishing. Both methods had similar efficiency in catching the bighead goby Ponticola kessleri and racer goby Babka gymnotrachelus.

AB  - The effects of physical factors on fish catch in the Serbian part of the Danube River were studied for period of six decades. The data on total catch for the Danube River from river kilometre 845 to river kilometre 1433 were collected from Statistical Office of the Republic of Serbia, while water level and water temperature data were collected from 16 water gauge stations along the investigated part of the Danube River for the period 1948–2009. Cross-correlation functions have been used to analyse the functional connection between Danube water level, water temperature and fish catch while ARMA model which combines cyclic (deterministic) and random (stochastic) components of the analysed sequences was used for the forecasts. The cross-correlation function showed negative correlation between water level and temperature as well as between water temperature and catch and positive correlation between water level and catch. The Danube water level and catch were coherent at the periods of 2.06, 4.13, 6.2, 10.33, 20.66 years, while the cross correlation function between these time series did not show phase lag. The results of reconstruction and forecast of water level, temperature, and catch of fish in the Danube River, obtained by summing the cyclic and stochastic components, was used for the forecast till 2029. In 2016, seven years after, the initial forecasts were made, validity of the model was checked by obtaining data for water temperature, water level and fish catch in the Danube River for the period 2010–2015. Model gave the best prediction for water temperature; average standard error was 1.6 times higher for predicted value than for model value while for fish catch and water level they were 1.96 and 4.97, respectively. Methods used in this work could be powerful tool for prediction of fish catch and serve as the basis for better fisheries management.

AB  - Pontic shad (Alosa immaculata Bennet 1835) is an anadromous species that lives in the heavily polluted north-western part of the Black Sea and migrates into the Danube River to spawn To assess their heavy metal contamination levels, samples of Politic shad were collected at 863 river kilometre of the Danube River Muscle, liver and gill samples were prepared using microwave digestion. and the analysis of Al, As, Cd, Cu, B. Ba. Fe, Mg. Sr. Zn. Li, Co, Cr. Mn. Mo, Ni and Pb was performed with inductively-coupled plasma-optic emission spectroscopy (ICP-OES). Significant differences in concentrations of analyzed elements were observed among different tissues, as well as between the genders Al, Sr, Ba. Mg, and Li had the highest concentrations in gills, while Cd. Cu, Zn. Fe and B were highest in the liver While the muscle had the lowest concentrations of most of the analyzed elements, it had the highest concentration of As.
