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  - 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  - Northern Pike is the top piscivore and phytophilic species strongly dependent on backwaters and vegetated river areas for spawning and recruitment. The aim of the present
study was to examine dependence between metal concentrations (As, Cr, Cd, Co, Cu, Fe,
Sr, Pb, Zn, Hg) and examined fish tissues, as well as of fish age. In June 2013, 26 samples
of pike have been collected using electrofishing (HONDA 1,2кW, 6 А). Collection was
performed in irrigation Channel Vizelj, runs through the suburban section of Belgrade.
The content of heavy metals was determined in samples of fish tissues of different ages
using inductively coupled plasma mass spectrometry (ICP-MS). Age analysis indicated
that fish belonged to age classes from 0+ to 2+. Metals As, Cd, Co and Pb were not detected in analyzed fish tissues, and Cu was not detected in muscle tissue of 2+ and 1+
specimens. The majority of the analyzed elements were found in minimal concentrations
in the muscle, except 0+ specimens with high Fe concentrations. Gills of all analyzed age
classes were loaded with very high concentrations of Fe and Sr. In gills of 1+ and 2+ fish
were also detected high Zn concentrations while in 0+ fish were detected Fe. The highest
concentrations of Cu were detected in liver of all fish age classes. The youngest age class
(0+) was differentiated by higher concentrations of Cr, Cu, Fe, Sr and Zn in muscle tissue,
while the oldest age class was mainly differentiated by higher concentrations for Zn and
Hg in gills.

AB  - The aim of this study was to describe biometric and feeding characteristics of highly invasive species Perccottus glenii in the investigated locality. A total of 85 fish were electrofished in the drainage channel located at the vicinity of Veliko Gradište (northeastern
Serbia) and preserved in the alcohol solution. In the laboratory, fish were measured (TL,
± 0.01 mm; W, ± 0.01 g), otholits and digestive tracts were removed for age determination
and dietary analysis (stereomicroscope). Biometric analysis included length-frequency
distribution using 10 mm class intervals; determination of average length and weight for
each age group; lenght-weigth relationship; Fulton’s condition factor. Ingested organisms
were identified to the lowest reliable taxonomic level (mainly order) and counted. The
respective ranges of TL and W of examined fish were 35-140.7 mm and 0.5-40 g. Length
class 70.1-80.0 mm clearly dominated (24%). Four age groups were determined (0+-3+),
and their descriptive statistics is presented. The value of allometric coefficient for the
length-weight relationship (b= 3.068) indicated isometric growth. Fulton’s condition factor did not differ between age groups. Empty digestive tract was found in 2 specimens. A
total of 12 prey categories representing Ephemeroptera, Trichoptera, Odonata, Hemiptera,
Chironomidae, Coleoptera, Gastropoda, Hirudinea, Oligochaeta, Gammaraidae, unidentified and terrestrial insects were identified in the diet. Generally, the diet is entirely composed of aquatic invertebrates, as only one terrestrial insect was found. Obtained results
did not show clear difference in diet composition between age groups. However, analysis
have shown that the most diverse diet characterize 2+ age. By frequency, the insect larvae
were categories with highest participation regardless of age.

were identified to the lowest reliable taxonomic level (mainly order) and counted. The
respective ranges of TL and W of examined fish were 35-140.7 mm and 0.5-40 g. Length
class 70.1-80.0 mm clearly dominated (24%). Four age groups were determined (0+-3+),
and their descriptive statistics is presented. The value of allometric coefficient for the
length-weight relationship (b= 3.068) indicated isometric growth. Fulton’s condition factor did not differ between age groups. Empty digestive tract was found in 2 specimens. A
total of 12 prey categories representing Ephemeroptera, Trichoptera, Odonata, Hemiptera,
Chironomidae, Coleoptera, Gastropoda, Hirudinea, Oligochaeta, Gammaraidae, unidentified and terrestrial insects were identified in the diet. Generally, the diet is entirely composed of aquatic invertebrates, as only one terrestrial insect was found. Obtained results
did not show clear difference in diet composition between age groups. However, analysis
have shown that the most diverse diet characterize 2+ age. By frequency, the insect larvae
were categories with highest participation regardless of age.",

AB  - In the Serbian part of the Danube River, of the 25 fish species recorded, five species from
the Gobiidae family have a participation with 10-20%. Since the early seventies, the
spreading of the gobiids along the Danube River has been reported, mainly owing to the
construction of dams and channels linking larger rivers. The round goby Neogobius
melanostomus is a fairly small bottom-dwelling fish, living in brackish and freshwater
environments. It is typically found near sandy, stony bottoms. This fish mostly stays in one
place with noticeably restricted movement. A patchy distribution and long distances
between native regions of occurrence and newly settled areas is characteristic for the
current world distribution of the species. Most probably, transport has occurred in ballast
waters. The aim of our study was to analyse the intestinal content of round goby in the
Serbian part of the Danube River Basin.
The fish samples were collected during October 2018 at three localities in the
Danube River (Zemun and Stari Slankamen) and Velika Morava River (Ljubičevo). A total of
35 individuals of round goby were collected and examined. Fish were caught with
electrofishing ((HONDA 1,2кW, 6 А) and transported to the laboratory, where the analysis
of their intestines for food items was conducted. The intestines were examined under an
Olympus binocular microscope and an Olympus stereomicroscope. Identification was
carried out to the species level, using the appropriate identification keys.
At the locality Ljubičevo, eight from 18 sampled specimens were without intestine
content. At the localities Zemun and Stari Slankamen, one specimen of ten and seven,
respectively, was without food items. The analysis showed that the intestinal content of
the round gobies consisted of representatives of the family Gammaridae (Dikerogammarus
sp.), insect larvae (Trichoptera), Gastropoda, Bivalvia (family Unionidae) and Oligochaeta.
The diet of fish samples from Ljubičevo consisted mostly of gammarids and oligochaets,
while this of fish from Zemun and Stari Slankamen from caddisfly larvae and molluscs.
Round gobies are voracious feeders, eating mussels and other molluscs, with up to 60% of
their diet made up of mussels in some places. They also eat aquatic insect larvae and the
young and eggs of other fish.

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.

AB  - Akvatični ekosistemi su danas ugroženi na globalnom nivou, stoga je u cilju održivog upravljanja vodenim resursima neophodno uspostaviti kontinuirani monitoring njihovog kvaliteta. Položaj riba na vrhu lanca ishrane i upotreba u ishrani ljudi čini ih važnim za procenu kontaminacije akvatičnih ekosistema toksičnim supstancama. U okviru ove disertacije vršena je procena distribucije različitih polutanata na tri lokacije na Dunavu: Batajnica, Veliko ratno ostrvo i Grocka, u periodu od novembra 2012. godine do marta 2014. godine. Na osnovu analize relativne zastupljenosti (abundancije) i masenog udela prisutnih vrsta riba u ukupnom ulovu, kao i bioloških i ekoloških karakteristika samih vrsta, na ispitivanim lokalitetima najpre jeodređenokoje vrste bi mogle biti optimalne indikatorske vrste, tako da su u daljim istraživanjima korišćeni štuka, deverika, krupatica,somi smuđ.

Potencijalna korelacija između koncentracije metala i elemenata u tragovima u mišiću sa koncentracijama u krljuštima i analnom peraju ispitana je na jedinkama štuke, deverike, krupatice, soma i smuđa, u cilju razvoja neinvazivnih metoda monitoringa kvaliteta ribljeg mesa. Takođe, ispitano je i prisustvo akumulacije organohlornih zagađivača (polihlorovanih bifenila i pesticida) kod jedinki deverike i smuđa primenom gasne hromatografije sa detektorom elektronskog zahvata(GC-ECD). Histopatološke promene praćene su na škrgama i jetri deverike i smuđa, kako bi se utvrdio potencijal korišćenja histoloških analiza u razvoju metoda monitoringa populacija riba. Rezultati su ukazali na visok nivo diferencijalne akumulacije elemenata među analiziranim tkivima u somu. Najviši sveukupni nivo akumulacije uočen je u kičmenom pršljenu, bubrezima i jetri, dok su minimalne vrednosti uočene u žučnoj kesi, mišiću, mozgu i ribljem mehuru. Akumulacija elemenata u mišiću i koži,kao i u škržnim filamentima i luku, značajno se razlikovala za većinu elemenata, dok između dva ispitivana dela jetre, proksimalnog i distalnog, nije bilo razlika u koncentracijama analiziranih elemenata. U proksimalnom i medijalnom segmentu creva uočen je isti akumulacioni nivo, dok su u oba segmenta zabeležene značajno više koncentracije Co i Zn i niže koncentracije Mn u odnosu na distalni segment. Nije uočena značajna korelacija koncentracija elemenata između mišića i krljušti kod ispitivanih vrsta, pa se može zaključiti da metoda korišćenja krljušti za procenu kontaminacije mišića datim elementimanije zadovoljavajuća, mada se može koristiti kao metoda ranog upozorenja na kontaminaciju tkiva.

Histopatološkom analizom utvrđene su više prosečne vrednosti nivoa histopatoloških promena u škrgama deverike, što je i očekivano imajući u vidu da su škrge riba u stalnom kontaktu sa supstancama koje se nalaze u vodi koja ih okružuje, pa predstavljaju relevantne indikatore izloženosti riba zagađivačima u vodi.

AB  - Aquatic ecosystems are today globally endangered;thus, in order to ensure sustainable water resources management, it is necessary to establish continuous monitoring of their quality. Considering that fish are situated at the top of the food chain and used for human nutrition, it makes them important for the assessment of contamination of aquatic ecosystems with toxic substances. In scope of this dissertation,the estimation of the distribution of different pollutants was carried out at three localities on the Danube: Batajnica, Veliko Ratno Ostrvo, and Grocka, in the period from November 2012 to March 2014. Based on the analysis of abundance and mass fraction of individual species in the total catch, as well as their biological and ecological characteristics, the optimal indicator species for this study were determined, and accordingly the following species were used northern pike, freshwater bream, white bream, wels catfish, and pike-perch. The distribution of 11 elements wasassessed in the wels catfish tissue samples by inductively coupled plasma mass spectrometry(ICP-MS), as well as their concentrations in different segments of muscles, gills, liver, and intestine, in order to determine the potential for the use of these tissues in monitoring fish populations. The potential relationship of metal and trace element concentrations in the muscle and their concentrations in scales and anal fins was assessed in northern pike, freshwater bream, white bream, wels catfish and pike-perch in order to develop non-invasive methods for monitoring the quality of fish meat. Using the gas chromatography with electron capture detector(GC-ECD), concentrations of organochlorine pollutants (polychlorinated biphenyls and pesticides) in freshwater bream and pike-perch were determined. Histopathological changes were assessed in gills and liver of freshwater bream and pike-perch in order to determine the potential for using histological analyses in the development of methods for monitoring fish populations. The results indicated a high level of differential accumulation of elements among the analyzed tissues in wels catfish. The highest overall accumulation level was observed in vertebra, kidneys, and liver, while minimal values were observed in gallbladder, muscle, brain, and swim bladder. The accumulation of elements in the muscle and skin, as well as in the gill filaments and gill arch, differed significantly among most elements, while between the two examined parts of the liver, proximal and distal, there were no differences in concentrations of the analyzed elements. The same accumulation level was observed in the proximal and medial segments of the intestine, while both segments had significantly higher concentrations of Co and Zn and lower Mn concentration in comparison with the distal segment. There were no significant correlations between muscle and scales in element concentrations in all investigated species, which indicates that the method of using scales is inadequate for assessing muscle contamination with these elements, but that it can be used as an early warning method for assessing overall tissue contamination. Concentrations of organochlorine contaminants were below the prescribed maximum allowed levels. While the accumulation of organochlorine compounds is affected by both the position of the fish in the food chain and the lipid content, no differences in concentrations of polychlorinated biphenyls and pesticides between the freshwater bream and pike-perch were observed in this study. Histopathological analysis revealed higher average histological scores in the gills of freshwater bream, which was expected, given that the gills are in constant contact with the substances found in the surrounding water, which makes them good indicators of fish exposure to pollutants in water. The total histopathological index of the liver did not differ significantly between species.

The accumulation of elements in the muscle and skin, as well as in the gill filaments and gill arch, differed significantly among most elements, while between the two examined parts of the liver, proximal and distal, there were no differences in concentrations of the analyzed elements. The same accumulation level was observed in the proximal and medial segments of the intestine, while both segments had significantly higher concentrations of Co and Zn and lower Mn concentration in comparison with the distal segment. There were no significant correlations between muscle and scales in element concentrations in all investigated species, which indicates that the method of using scales is inadequate for assessing muscle contamination with these elements, but that it can be used as an early warning method for assessing overall tissue contamination. Concentrations of organochlorine contaminants were below the prescribed maximum allowed levels. While the accumulation of organochlorine compounds is affected by both the position of the fish in the food chain and the lipid content, no differences in concentrations of polychlorinated biphenyls and pesticides between the freshwater bream and pike-perch were observed in this study. Histopathological analysis revealed higher average histological scores in the gills of freshwater bream, which was expected, given that the gills are in constant contact with the substances found in the surrounding water, which makes them good indicators of fish exposure to pollutants in water. The total histopathological index of the liver did not differ significantly between species.",

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  - Veliki kormoran se u potpunosti hrani ribom. Dnevna količina hrane koju veliki kormoran pojede kreće se između 425-700 grama, odnosno u proseku od 15 do 17 % svoje telesne težine. Opsežnija istraživanja ishrane velikih kormorana u Srbiji nisu vršena. Jedini podaci o ishrani kormorana i drugih ihtiofagnih vrsta ptica kod nas odnose se na štete koje one nanose proizvodnji ribe na ribnjacima. Podaci o ishrani kormorana van ribnjaka odnose se na ishranu tokom sezone gnežđenja u koloniji u Kopačkom ritu i zimsku ishranu na akumulaciji Gruža. Analiza ishrane velikog kormorana i značaj šarana u njegovoj ishrani rađena je na području Specijalnog rezervata prirode „Carska bara”. U periodu od 2007 do 2010 godine prikupljane su gvalice za analizu ishrane velikog kormorana. Gvalice su prikupljane u dve sezone: sezona gnežđenja (mart-jun) i jesenje-zimskom periodu (oktobar-februar). Prikupljane su na mestima gde se ptice odmaraju iu samom mestu gnežđenja. Analiza gvalica je najčešće korišćen metod analize ishrane kod kormorana. U periodu oktobar–februar, 2007 – 2010. godine prikupljeno je 507 gvalica iz kojih su identifikovani ostaci 2433 jedinke od 16 različitih vrsta riba, od kojih je 9 vrsta bilo iz familije Cyprinidae, zatim tri vrste iz familije Percidae i po jedna vrsta iz familija Gadidae, Esocidae, Ictaluridae i Gobiidae. Ostaci šarana identifikovani  su u 184 gvalice (36,29%). Šaran je u ovom period bio zastupljen sa 18,10%, u pogledu brojnosti. Po masenom udelu u plenu najznačajnija je vrsta, sa učešćem od 36,24%. 
Tokom sezona gnežđenja od 2007. do 2010. godine prikupljeno je 80 gvalica. U plenu, identifikovanom iz gvalica, po brojnosti su dominirale dve vrste, babuška i šaran, a registrovano je prisustvo 11 vrsta riba iz 5 familija (6 Ciprinidae, 1 Ictaluridae, 1 Esocidae, 1 Percidae,1 Gobiidae). Ostaci šarana su registrovani u 44 (55%) gvalica. Šaranske vrste riba su još značajnije zastupljene u ishrani kormorana tokom sezone gnežđenja nego u jesenjem i zimskom periodu. Tako, one čine 85% ukupnog broja ulovljenih jedinki, a udeo u  biomasi plena je oko 90%. Rezultati istraživanja ishrane velikih kormorana na području Carske bare u skladu su sa mnogim studijama sprovedenim širom Evrope.

Analiza ishrane velikog kormorana i značaj šarana u njegovoj ishrani rađena je na području Specijalnog rezervata prirode „Carska bara”. U periodu od 2007 do 2010 godine prikupljane su gvalice za analizu ishrane velikog kormorana. Gvalice su prikupljane u dve sezone: sezona gnežđenja (mart-jun) i jesenje-zimskom periodu (oktobar-februar). Prikupljane su na mestima gde se ptice odmaraju iu samom mestu gnežđenja. Analiza gvalica je najčešće korišćen metod analize ishrane kod kormorana. U periodu oktobar–februar, 2007 – 2010. godine prikupljeno je 507 gvalica iz kojih su identifikovani ostaci 2433 jedinke od 16 različitih vrsta riba, od kojih je 9 vrsta bilo iz familije Cyprinidae, zatim tri vrste iz familije Percidae i po jedna vrsta iz familija Gadidae, Esocidae, Ictaluridae i Gobiidae. Ostaci šarana identifikovani  su u 184 gvalice (36,29%). Šaran je u ovom period bio zastupljen sa 18,10%, u pogledu brojnosti. Po masenom udelu u plenu najznačajnija je vrsta, sa učešćem od 36,24%. 
Tokom sezona gnežđenja od 2007. do 2010. godine prikupljeno je 80 gvalica. U plenu, identifikovanom iz gvalica, po brojnosti su dominirale dve vrste, babuška i šaran, a registrovano je prisustvo 11 vrsta riba iz 5 familija (6 Ciprinidae, 1 Ictaluridae, 1 Esocidae, 1 Percidae,1 Gobiidae). Ostaci šarana su registrovani u 44 (55%) gvalica. Šaranske vrste riba su još značajnije zastupljene u ishrani kormorana tokom sezone gnežđenja nego u jesenjem i zimskom periodu. Tako, one čine 85% ukupnog broja ulovljenih jedinki, a udeo u  biomasi plena je oko 90%. Rezultati istraživanja ishrane velikih kormorana na području Carske bare u skladu su sa mnogim studijama sprovedenim širom Evrope.",

AB  - Veliki kormoran (Phalacrocorax carbo Linnaeus, 1758) je najšire rasprostranjena vrsta roda Phalacrocorax i naseljava sve kontinente izuzev Južne Amerike i Antarktika. Ova vrsta je u ekspanziji u celoj Evropi. Njegov broj rapidno raste od 80-ih godina prošlog veka. Sada je brojniji i rasprostranjeniji u Evropi nego u bilo kom trenutku u poslednjih 150 godina. Populacije su se vratile na neka područja posle dugog odsustva, a pojavile su se i u oblastima u kojima ih u prošlosti nije ni bilo. U Srbiji su prisutni na svim većim rečnim tokovima, kao i veštačkim akumulacijama i ribnjacima. Parazitska fauna velikog kormorana u Srbiji do sada nije izučavana tako da rezultati ovog istraživanja predstavljaju prve podatke o crevnim parazitima ove vrste kod nas.
Tokom 2010 i 2015 godine prikupljeno je 29 jedinki i izvršen je parazitološki pregled crevnog trakta. Osam jedinki je poticalo sa lokaliteta Marin Sprud, koji se nalazi nekoliko kilometra nizvodno od ušća Drave u Dunav a 21 ptica je poticala sa ribnjaka Ečka u centralnom Banatu. Crevni paraziti su morfometrijski determinisani po ključu za determinaciju Anderson (1992).
Contracaecum rudolphii je ustanovljen kod 14 ptica (kod svih sa Dunava i 6 iz Ečke) a Syncuaria squamata je nađena kod 4 kormorana sa Dunava i 11 iz Ečke. Poliparazitizam je nađen kod 10 kormorana. Nađene vrste Nematoda su najčešće sretane kod kormorana iz centralne i severne Evrope (Kanarek, 2011, Moravec i Scholz, 2016). Ovo su prvi nalazi ovih parazita u Srbiji.

AB  - U srpskom delu Dunava, od zabeleženih 25 alohtonih vrsta riba, pet vrsta iz familije Gobiidae nastanjuju 10-20% teritorije Srbije (Lenhardt et al., 2011). Od ranih sedamdesetih, zabeleženo je širenje glavoča duž Dunava, uglavnom zahvaljujući izgradnji brana i kanala koji povezuju veće reke (Brandner 2014). U skorije vreme, primećeno je značajno širenje ponto-kaspijskih glavoča u vodama Srbije  (glavoč peskar) (Đikanović et al., 2013). 
Tokom ekspedicije Treće zajedničko istraživanje Dunava (Joint Danube Research-JDS3) sprovedene 2013. godine uzorkovano je 18 jedinki glavoča na sedam lokaliteta, duž sektora Dunava 1.481 – 60 rkm. Lokaliteti su: Bajac (1.481 km), Stari Slankamen (1.216 km), Pančevo nizvodno (1.151 km), Stara Palanka-Ram (1.077 km), Golubac-Koronin (1.040 km), Tekija (954 km), Valkov-Kilija, delta Dunava (60 km).
Pregledom crevnog trakta, primenom standardnih metoda, identifikovano je 30 jedinki endoparazita iz klasa Nematoda (Raphidascaris acus-11, Cammalanus truncatus-2) i Trematoda (Nicolla skrjabini-17). Nađeno je i 20 cista metilja (Trematoda). Od 18 sakupljenih i pregledanih jedinki glavoča, samo jedna nije bila zaražena.
U površinskim vodama Srbije, kao ni u srpskom delu Dunava, do sada nisu vršena istraživanja crevnih parazita glavoča, tako da prikazani rezultati imaju značaja sa aspekta diverziteta endoparazita u Srbiji, i sa aspekta posledica bioloških invazija na nativnu ihtiofaunu.

AB  - The Velika Morava River is the greatest national Serbian river and the significant tributary of the Danube River. The major problems in the Velika Morava River Basin (VMRB) represent untreated industrial and municipal wastewaters. In this study, the level of genotoxic potential at the sites along the VMRB was evaluated by parallel in vitro and in situ approach. Within in vitro testing, genotoxicity of native water samples collected from the sites in VMRB was evaluated by SOS/umuC test on Salmonella typhimurium TA1535/pSK1002 and by the comet assay on HepG2 cells. DNA damage in situ was assessed in bleak (Alburnus alburnus) erythrocytes by the comet (alkaline and Fpg-modified comet) and micronucleus assays. Additionally, the concentration of heavy metals in fish tissue was measured and this data, compiled with the data of the physico-chemical parameters measured in water, was used as a measure of the pollution pressure at the sites. Results showed that applied in vitro tests with native water samples are less sensitive in comparison with in situ tests and should be taken with precaution when making predictions on the status of the ecosystem. Within applied battery of in situ assays differential sensitivity of assays was observed where alkaline comet assay showed the highest potential in differentiation of the sites based on genotoxic potential. Integrated biomarker response showed that usage of the battery of bioassays provides better insight in a genotoxic effects in animals, and consequently, that the holistic approach is more suitable for this type of study.

AB  - We employed geometric morphometric techniques to investigate external (body) morphology of European grayling (Thymallus thymallus) populations from the wild and hatchery facilities. Wild graylings were representative of Balkan and Caspian phylogenetic clades, whereas hatchery-reared specimens originated from Balkan and Adriatic phylogenetic clades. Individuals of T. thymallus from the Adriatic phylogenetic clade were the largest, followed by those from the Balkan phylogenetic clade, while graylings from the Caspian phylogenetic clade were the smallest. Graylings from hatchery facilities were larger than graylings from the wild. Body shape variation in T. thymallus coincides with genetic differentiation of the analyzed populations, whereas it is less influenced by difference in environment they experience in wild and captive habitats. Although hatcheries can generate large numbers of individuals, some of which will have an extreme phenotype, the variance in body shape was similar in captive and wild populations. Allometric relations were different between specimens from the wild and from hatchery facilities, as well as among those belonging to different phylogenetic clades. Allometric analyses performed separately for the wild and hatchery-reared populations revealed significant effect of allometry and similar trends in size-related shape variation among populations from different phylogenetic clades. We found that phenetic relationships among the studied wild grayling populations inferred from non-allometric body shape variation better reflected their phylogenetic relationships than equivalent data from hatchery populations.

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.

AB  - In this review data on parasitofauna of allochthonous fish species in the Danube River Basin in Serbia is presented. Up to now, 33 ecto-and endoparasites of seven examined allochthonous invasive fish species have been reported. Some of the identified parasitic species are new for fish parasitofauna in the Serbian waters (Trichodina nobilis, Balantidium sp., Philometroides cyprini, Philometroides parasiluri, Eustrongylides sp., Ergasilus sieboldi, Lernaea cyprinacea, Sinergasilus polycolpus). In the open waters of Serbia (the Danube River Basin) a total of 26 non-indigenous fish species were recorded, of which 16 were the allochthonous invasive fishes. The major means of introductions and translocations were found to be the aquaculture, fish stocking and transportation. Habitat modification was found to be the factor that largely contributes to the capability of the water bodies to become a suitable recipient area. The large presence of alien fish species (27.66%) and its parasites creates a serious threat to the stability of freshwater ecosystems and the survival of the native ichthyofauna. The main environmental consequences of alien fish spreading are related to the alteration in fish community structure and function, as well as the introduction of the alien parasite species.

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.
