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  - 1.	Black bullhead is among the most abundant and successful non-native fish species in European freshwaters. A number of studies have indicated that its physical removal could be a potential solution to minimize possible negative impacts that it may have on native fishes; however, so far there have been no field studies to confirm this.
2.	This study quantified population dynamics of both native and non-native fishes in a small slow-running lowland river within the Ponjavica Nature Park in Serbia before and after the black bullhead removal with fyke-nets, which proved to be an efficient tool for this purpose.
3.	The removal of black bullhead resulted in statistically significant changes in two native species abundance – an increase of rudd (Scardinius erythrophthalmus) (by 5.3 times), and a decline of bleak (Alburnus alburnus) (by 2.3 times).
4.	Significant increase was observed in three non-native fish species: the abundances of topmouth gudgeon (Pseudorasbora parva), pumpkinseed (Lepomis gibbosus), and Prussian carp (Carassius gibelio) increased 25.5, 4.9, and 4.2 times, respectively.
5.	There were also substantial changes in the diversity of the fish assemblage after the black bullhead removal, illustrated by changes in diversity indices: Shannon's index doubled, while the Simpson’s dominance index decreased threefold.
6.	The catch-per-unit-effort and the biomass-per-unit-effort values indicated the dominance of the black bullhead in the fish assemblage. YOY/adult ratio did not vary in relation to abundance, which confirmed that black bullhead might not compensate for fishing mortality with the increased recruitment.
7.	The results suggest that black bullhead plays a significant role in structuring the fish assemblage and that its removal may have both positive and negative effects on species abundance and diversity. These findings can contribute to the conservation of native fish species and improvement of future management programs.

AB  - In the sake of better understanding of the mechanisms that drive interactions between
invasive species and their ecosystems, results of selective removal of the black bullhead
(Ameiurus melas) in two different lentic systems were compared. Ponjavica Nature Park has
characteristical watercourse of the plains with very slow flow and the coastal remains of
wetlands. Markovačko reservoir was built for the needs of the irrigation system of the
nearby agricultural land. Both systems suffer dominance of the black bullhead,
characterized as a species of "globally high risk". Combining results of the mass removal,
the effects on the native fish populations have been empirically demonstrated and
quantified. Black bullhead selective removal in Ponjavica lasted from August - October
2018, April - September 2019, with 20,145 black bullhead individuals removed. It showed
decreased abundance of bleak (Alburnus alburnus) 2.3 times, while the abundances of
roach (Rutilus rutilus) and European perch (Perca fluviatilis) remained almost unchanged. A
significant increase in abundance was recorded in rudd (Scardinius erythrophthalmus) (5.3
times). The abundances of topmouth gudgeon (Pseudorasbora parva), pumpkinseed
(Lepomis gibbosus), and Prussian carp (Carassius gibelio) increased 25.5, 4.9, and 4.2 times,
respectively. The mass removal of black bullhead on Markovačko Lake lasted from August -
October 2020, April - September 2021, and 15,921 black bullhead specimens were
removed. When the post removal state from Markovačko lake was determined, two species
appeared in the sample for the first time: European perch and chub (Squalius cephalus). The
abundance of bleak increased 3 times, abundance of Prussian carp reduced 8 and black
bullhead 16 times. The abundance of roach decreased 11, rudd 10, pike-perch (Sander
lucioperca) 4 and freshwater bream (Abramis brama) 2 times. The abundances of
pumpkinseed increased 10, Monkey goby (Neogobius fluviatilis) 3 and topmouth gudgeon
2.5 times. The results showed that the fyke nets can be most effectively and selectively
applied to control the abundance of black bullhead, because simplicity and nonharmfulness
to other species. It is not possible to completely remove this species from the
ecosystem, but reduce the negative impact by suppression (removal programs) and
containment of existing state is crucial.

AB  - Individuals of common nase were sampled from three waterbodies (Kačer river, Zaovine, and Medjuvršje reservoirs) with different characteristics, types, and levels of anthropogenic pressure. The aims of this study were to determine the concentra-tions of 26 elements in gills, liver, and muscle using inductively coupled plasma optical emission spectrometry (ICP-OES); determine the concentrations of 17 organochlorine pesticides (OCPs) in muscle tissue using gas chromatography with mass spectrometric detection (GC–MS); compare these findings with fish condition (CF); and conduct human health risk and benefit assessments due to consumption of fish meat using target hazard quotient, target carcinogenic risk factor, Se:Hg molar ratio, Na:K and Ca:Mg ratios, and contribution of elements to human diet. Results indicated that in addition to the fact that the type of ecosystem (lentic vs. lotic) plays an important role in the fate and kinetics of pollutants, the degree of anthropogenic pressure is one of the most important factors of environmental pollution — Zaovine and Medjuvršje reservoirs (both lentic ecosystems) had the lowest and the highest levels of pollution, respectively. CF did not reflect the differences in accumula-tion of all analyzed elements in nase tissues. None of the 17 analyzed OCPs were detected due to the absence of recent use. Fish muscle was the least affected by metal pollution at all studied localities and could be safely used for consumption. We recorded several benefits for human health when using the nase meat in human diet.

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  - In the last decade, the consumption trend of honey has increased dramatically in the world. The reason is the growing emphasis on the consumption of honey due to its positive effects on health due to the antibacterial and antioxidant properties of honey. On the other hand, pesticides, especially insecticides and acaricides, are the main causes that can contaminate honey and compromise its quality. For that reason, the determination of these pollutants is necessary and important, since the use of pesticides is increasing every year due to the need to produce food, and many of them are in the environment for a long time after use. In this way, bees and honey can be classified as environmental indicators. Modern techniques, such as gas chromatography with mass detection, have the ability to detect a large number of pesticides simultaneously at the trace level. Extraction of pesticides from honey is a great analytical challenge due to the complexity of the matrix containing about 300 chemical compounds from different groups such as sugars (monosaccharides and oligosaccharides), organic acids, amino acids, enzymes, hormones, flavonoids, vitamins, essential oils and sterols. Different approaches based on novel sorbents for clean-up step in preparation procedure have been recently evaluated in order to obtain satisfactory method validation parameters. A quick purification method using dispersive solid phase extraction provides a way to obtain pure extracts with excellent recovery results. In recent years, a large number of scientific publications have developed a sensitive and accurate method for pesticide residue determination in honey samples. The focus of the research was on the validation of the method for the determination of organochlorine pesticides, amitraz and 2, 4 dimethylaniline in honey produced in Serbia. The aim was to validate the method in order to find the most reliable answer to the question about the safety of honey in the territory of the Republic of Serbia and the answer to the question about the presence of pesticide residues in honey. The results of the research are the results of the obtained analyzes on the presence of pesticides in different types of honey from Serbia. Further it gives an overview of the results of other authors, as about the latest results of the examined honey and the presence of contaminants in the surrounding countries.

AB  - Lepomis gibbosus (pumpkinseed) was first recorded as a non-native fish in Serbia in the
1930s in the Tisza River. The species currently inhabits almost the entire region of the Black
Sea basin in Serbia, but has no economic value. The current range of the pumpkinseed
covers more than 50% of the total Serbian area and is also naturalised in Serbian waters.
The pumpkinseed feeds on bottom fauna, small fish, fish roe and juvenile fish, which
together with competition for habitat and spawning sites can have a negative impact on
native species. The most common prey of younger specimens is zooplankton, while adult
specimens feed on larger organisms such as larvae and pupae of insects, molluscs or
crustaceans. The composition of the prey varies seasonally and depends on the
composition of the community. The main objective of the study was to analyse the
differences in the feeding habits of pumpkinseed in five reservoir.
Samples were collected from five reservoirs in central Serbia (<200 asl, Markovačko,
Topola, Vlaški Do, Jatagan, Kudreč) using standard electrofishing equipment. All sampled
reservoirs had mud substrate, except Jatagan Reservoir, which had gravel substrate. The
sampled fish were identified on site based on morphological characteristics using
identification keys. The sampled fish were measured using total body length and weight.
The total sample consisted of 354 pumpkinseed individuals whose body weight ranged
from 3.66–9.52 g and body length from 6.01–8.41 cm. The number of individuals with
intestinal content was 282, while the number of individuals with empty stomachs was 72.
The following macroinvertebrate taxa were identified during the examination of the gut
contents: aquatic insects (Chironomidae, Chironomidae-pupae, Diptera, Ceratopogonidae,
Trichoptera, Ephemeroptera, Odonata, Heteroptera, Coleoptera), Gammaridae, Mollusca,
Bivalvia, Gastropoda, Nematoda. Undetermined terrestrial insects were also recorded. Most
prey were found in the Kudreč Reservoir, and the greatest diversity was in the Topola
Reservoir. Jatagan Reservoir had the lowest number of prey items, which may be due to
the substrate type. The high number of aquatic insect taxa could be explained by the small
surface area of the reservoir and the presence of aquatic vegetation.

AB  - Otoliths are calcareous structures commonly used for fish age, size, and taxon determination. Information obtained from the analysis of otoliths can be of great importance for the management of fish populations, including invasive fish species. Pumpkinseed (Lepomis gibbosus) is one of the most successful invaders of Serbian freshwaters. It preys on aquatic invertebrates, fish eggs, and small fish. This species shows high plasticity of life history traits and can tolerate harsh environmental conditions, including hypoxia and high water temperatures. In October of 2020, a total of 28 pumpkinseed individuals from Topola reservoir (44.268229 N, 20.691564 E) were caught with electrofishing device Villager VGI2400 (230 V, 8.7 A, 2.0 kW). In order to determine relationships of otolith to fish size, a total length (TL) and body weight (BW) of each fish were measured as well as otolith area (OA), perimeter (OP), length (OL), and weight (OW). There were no significant differences between left and right otolith regarding OA, OP, OL, and OW (t-test, P>0.94). Significant and strong correlations were recorded for TL and OA (r2=0.936, P<0.0001), TL and OP (r2=0.958, P<0.0001), TL and OL (r2=0.945, P<0.0001), and TL and OW (r2=0.838, P<0.0001). Additionally, significant and strong correlations were recorded for BW and OA (r2=0.844, P<0.0001), BW and OP (r2=0.819, P<0.0001), BW and OL (r2=0.828, P<0.0001), and BW and OW (r2=0.795, P<0.0001). Results indicated that TL-OP relationship is the best predictor of pumpkinseed length, while BW-OW relationship is the weakest predictor of pumpkinseed weight. The common linear regression equations were determined: y = 0.9004x + 3.2643 for OA-TL, y = 0.9079x – 0.4816 for OP-TL, y = 2.4873x – 0.6667 for OL-TL, y = 523.2832x + 5.2364 for OW-TL, y = 3.2985x – 9.6439 for OA-BW, y = 3.2389x – 22.5237 for OP-BW, y = 8.9825x – 23.5786 for OL-BW, and y = 1966.5664x – 2.7114 for OW-BW. The obtained equations allow the calculation of pumpkinseed TL and BW based on the set of data on the morphological characteristics of the otoliths. Of the considered otolith parameters, otolith weight is the least suitable character for estimation of pumpkinseed size.

AB  - White bream is an important species in commercial and sport fishing that is caught in nets throughout the year. The analyzed samples of white bream (n = 377) came from commercial catches carried out between December 2014 and May 2015 at two locations in the Danube near Belgrade, Jojkića Dunavac (JD) – an armlet of the Danube, with slow water flow and Veliko ratno ostrvo (VRO) – the main channel of the Danube, with fast water flow. Total body length (TL, cm) and body weight (BW, g) of each fish were measured, and Fulton's condition factor (K = W/L3 x 100) was calculated.
Average TL of the fish samples from the JD and VRO were 23.1±1.7 and 23.8±2.4, respectively, and average BW were 164.4±42.2 and 201.0±73.0, respectively. In general, fish from VRO were in better condition (K=1.44±0.16) compared to sample from JD (K=1.31±0.11). Individuals in the sample from JD had a negative allometric growth (a = -1.79, b = 2.93, r² = 0.85), while those from VRO have a positive allometric growth (a = -2.22, b = 3.28, r² = 0.89). Based on the results of this study, positive allometric growth (b > 3) and fish condition indicated that individuals from VRO increased body mass more than body length. The source of food, its availability, and better habitat conditions at VRO could be the reason for the differences in the growth and condition of the fish from the investigated locations.

AB  - The stomach content of 277 Amur sleeper individuals has been analyzed to present its
feeding habits. Fish were sampled using electrofishing from July to November 2017 in
the Danube River drainage channel near Veliko Gradište (Serbia). Fish age was
estimated by otoliths examination. Ingested prey organisms were identified to the
lowest reliable taxonomic level. The biotic indices: vacuity index (VI), frequency of
occurrence (F), abundance (Cn), index of importance (PV), Shannon’s diversity index
(H’), and equitability index (Eh) were calculated. A total of 18 prey categories and 1144
individual prey were identified in the fish diet, dominantly aquatic macroinvertebrates.
There were no significant difference in diet composition between sampling months as

AB  - The European eel (Anguilla anguilla), a catadromous, critically endangered species,
was the subject of this study. The main goal was to determine the status of populations
of European eel in the waters of the Republic of Serbia. The research included both
fieldwork (27 sampling sites) and the literature data analysis for all three river basins
in Serbia: Aegean, Adriatic, and Black Sea. The methodology of data collection and
determination of European eel presence differed from basin to basin. The fish were
identified, measured, noted and immediately returned to the water. The waters that
belong to the Aegean basin in Serbia could not be considered anymore as a natural
habitat for the European eel, although it inhabits the middle and lower reaches of the
rivers that belong in Bulgaria, Greece and North Macedonia. The rivers of the Adriatic
basin were not available for sampling; therefore, just literature data were collected.
Insufficient literature data on the presence of European eels in waters of the Black Sea
basin in the last decade imposed using of inquiry survey with commercial fishermen
about occurrence of European eels in their catches. Total of 54 commercial fishermen
were surveyed at 31 locations on the Danube, Sava and Tisza. Results showed presence
of both silver and yellow stages. The survey showed that there is a linkage between
the time and manner of occurrence of the life stages. The collected data were
georeferenced and the area where European eels were recorded was defined. Based on
the hypothetical projection, according to statistical data, annual catch reached 1352 kg
in the Danube, Sava and Tisza. Recent data (2015 to 2019) are predominantly related
to the Danube, which can be correlated to the connection between the Black and North
Seas (Rhine-Main-Danube canal connection). This study shows that the appearance of
the juvenile migration stages of European eels is not unimportant and deserves more
research attention.

AB  - North American black bullhead (Ameiurus melas) is an ictalurid species that has become
widespread outside of its native range, causing undesirable ecological impacts. Numerous
studies have suggested that its physical removal could be a way to reduce any potential
detrimental effects of this species. This study measured the effects on population dynamics of
both native and non-native fish species following the removal of 20,145 black bullheads from
the Ponjavica Nature Park. The most significant changes between the zero-point state and the
post-removal state have been recorded among the populations of non-native fish species: the
abundances of topmouth gudgeon (Pseudorasbora parva), pumpkinseed (Lepomis gibbosus),
and Prussian carp (Carassius gibelio) increased 25.5, 4.9, and 4.2 times, respectively.
Previous research has shown that smaller black bullhead individuals enter into competitive
relationships with the topmouth gudgeon, while larger individuals use the topmouth gudgeon
as prey. By removing black bullhead individuals from the ecosystem, a part of the ecological
niche used by both species was freed. Also, the predatory pressure on topmouth gudgeon
decreased by removing larger black bullhead individuals. All these factors led to an increase
in the abundance of topmouth gudgeon. Black bullhead and pumpkinseed have overlapping
diets and are therefore considered competitors for food. Moreover, research on the black
bullhead's feeding ecology showed that this species feeds on the pumpkinseed. When a
greater number of black bullhead individuals were removed from the ecosystem, it led to an
increase in the abundance of pumpkinseed. The abundance of Prussian carp also increased
after the removal of the black bullhead. The Prussian carp and the black bullhead are quite
similar in terms of diet habits, habitat preferences, and reproductive characteristics. Since
these two species are in direct competition, the decline in the black bullhead population
contributed to an increase in the Prussian carp population. These results point to the fact that
management programs must include multiple species and methods, and one of them is the
removal of all undesirable, invasive non-native species. Further research should also focus on
possible diet shifts in allochthonous fishes after removing the black bullhead.

AB  - Узорци риба из реке Црни Тимок прикупљени су методом електрориболова у августу 2020. године. Процена диверзитета заједнице извршена је помоћу Shannon-овог индекса (H)1, а метода Pantle-Buck-а2 коришћена је за израчунавање укупаног индекса сапробности (S). Циљ овог истраживања било је утврђивање еколошког статуса и квалитета воде на основу квалитативног и квантитативног састава рибље заједнице. Забележено је присуство 13 врста – поточна мрена (Barbus balcanicus), клен (Squalius cephalus), скобаљ (Chondrostoma nasus), двопругаста уклија (Alburnoides bipunctatus), кркуша (Gobio obtusirostris), гаовица (Rhodeus amarus), пиор (Phoxinus phoxinus), пеш (Cottus gobio), поточна пастрмка (Salmo trutta), вијун (Cobitis elongatoides), балкански вијун (Sabanejewia balcanica), бркица (Barbatula barbatula) и паклара (Eudontomyzon spp.). Приближно трећину узорка чинила је двопругаста уклија (31,6%), док је пеш био следећа врста по абунданцији (17,7%). Релативна заступљеност поточне пастрмке, бркице и пакларе била је мања од 1%. Забележен је H од 2,05, па према квалитету воде река Црни Тимок спада у II-III класу. Са друге стране, вредност S износила је 1,37, што одговара олигосапробној води I класе бонитета (чиста или веома мало загађена вода). Потребно је истражити друге групе индикаторских организама (нпр. микроорганизми, макрозообентос) и испитати физичко-хемијске и биолошке карактеристике воде Црног Тимока како би се прецизније проценио његов еколошки статус.

Процена диверзитета заједнице извршена је помоћу Shannon-овог индекса (H)1, а метода Pantle-Buck-а2 коришћена је за израчунавање укупаног индекса сапробности (S). Циљ овог истраживања било је утврђивање еколошког статуса и квалитета воде на основу квалитативног и квантитативног састава рибље заједнице. Забележено је присуство 13 врста – поточна мрена (Barbus balcanicus), клен (Squalius cephalus), скобаљ (Chondrostoma nasus), двопругаста уклија (Alburnoides bipunctatus), кркуша (Gobio obtusirostris), гаовица (Rhodeus amarus), пиор (Phoxinus phoxinus), пеш (Cottus gobio), поточна пастрмка (Salmo trutta), вијун (Cobitis elongatoides), балкански вијун (Sabanejewia balcanica), бркица (Barbatula barbatula) и паклара (Eudontomyzon spp.). Приближно трећину узорка чинила је двопругаста уклија (31,6%), док је пеш био следећа врста по абунданцији (17,7%). Релативна заступљеност поточне пастрмке, бркице и пакларе била је мања од 1%. Забележен је H од 2,05, па према квалитету воде река Црни Тимок спада у II-III класу. Са друге стране, вредност S износила је 1,37, што одговара олигосапробној води I класе бонитета (чиста или веома мало загађена вода). Потребно је истражити друге групе индикаторских организама (нпр. микроорганизми, макрозообентос) и испитати физичко-хемијске и биолошке карактеристике воде Црног Тимока како би се прецизније проценио његов еколошки статус.",

AB  - Five reservoirs (Vlasina, Medjuvršje, Zaovine, Perućac, and Garaši) in Serbia were chosen as study sites, which differ by their position, purpose, stages of eutrophication, management policies, and levels of anthropogenic pressure. The objectives of this research were to: determine the concentrations of 26 elements in muscle, gills, and liver of the European chub by inductively-coupled plasma optical emission spectrometry (ICP-OES); determine the concentrations of 17 organochlorine pesticides in fish muscle by gas chromatography with mass spectrometric detection (GC-MS); compare these findings with condition factor (CF) and histopathological (HP) biomarkers; and assess the potential human health risks due to consumption of chub muscle tissue. The highest elemental accumulation was found in the gills. The European chub was not a good indicator of Pb pollution between reservoirs. Concentrations of Hg, As, and Cu were low and did not exceed the proscribed maximum
allowed concentrations (MACs). 4,4′-DDE was detected only in individuals from Vlasina, 4,4′-DDD from Perućac
and Zaovine, and heptachlor from Zaovine. Low to moderate levels of HP were observed for both gills and liver in all studied reservoirs. HP index for gills was significantly higher for Zaovine compared to Vlasina. Significantly lower HP index for liver and the total HP index value were observed for fish from Vlasina compared to Perućac. No significant human health risks due to the intake of examined pollutants in each reservoir were recorded; women were at higher risk compared to men. A reason for concern is a few muscle samples from Garaši, Vlasina, Perućac, and Medjuvršje in which Cd exceeded the MAC. A reservoir for water supply (Garaši) is generally considered the safest for fish consumption.

AB  - The objective of our study was to investigate ecological status of two water bodies in Serbia, Lake Kruščica, and River Ibar. The comet assay was selected as an in vivo and in situ test for measuring DNA damage in chub’s erythrocytes, as an bioindicator of genotoxic potential of water. We have also investigated physico-chemical parameters and microbiological indicators (coliforms, E.coli) as parameters for general pollution pressure and a basis for determination of ecological status of these water bodies. Lake Kruščica is a protected natural area of great importance with very low or none anthropogenic impact, used as a drinking water source. River Ibar is under intensive multisource pressure pollution consisted of: communal untreated waters, industrial, agricultural and mining activities. Specimens of chub analyzed in this study naturally inhabit these water bodies, which gave us an excellent opportunity to compare protected site with site where mixture of various xenobiotics from water have a direct and adverse impacts over period of time. According to physico-chemical parameters and microbiological indicators, Lake Kruščica falls into the first category of ecological status, while River Ibar showed poor to critical water quality. DNA damage in chub erythrocytes was significantly higher at River Ibar compared to Lake Kruscica, which indicates the notable difference in pollution pressure. Given its tolerance to anthropogenic perturbations, and its cosmopolite distributions, chub gives an advantage for extensive studies of genotoxicity dynamics of freshwater systems.

AB  - Анализа алометријског раста указује на то да ли рибе повећавају своју висину и/или ширину значајније него што повећавају дужину тела.1 Утврђивање дужинско-тежинског односа и Фултоновог фактора кондиције код плотице рађено је на три акумулације (Кокин брод, Радоиња и Увац). Узорци су прикупљени помоћу стајаћих мрежа (димензија 30 m × 2 m, промера окаца 28-100 mm), које су остављене у води да преноће. На основу измерених тоталне дужине тела (TL, cm) и масе тела (W, g), свакој јединки је израчуната и њена кондиција, по формули за Фултонов фактор кондиције: K = W/TL3 × 100.2 Највеће средње дужине и масе тела (± SD) забележенe су код јединки из акумулације Златар (34,6 ± 12,8 cm и 672 ± 639 g), праћене јединкама из Радоиње (30,9 ± 15,2 cm и 563 ± 525 g), док су плотице из Увац (20,8 ± 7,5 cm и 140 ± 191 g) биле ситније. Кондиција код плотице из свих акумулација је била уједначена, са вредностима К = 1,09 (Златар), К = 1,07 (Увац) и К = 1,07 (Радоиња). Позитиван алометријски раст забележен је код плотица из свих анализираних акумулација, са највећим вредности на Златару (a = –2,245; b = 3,19; r² = 0,99) и Радоињи (a = –2,234; b = 3,18; r² = 0,99), док су нешто ниже биле на Увцу (a = –2,049; b = 3,06; r² = 0,98). На основу резултата ових истраживања, позитиван алометријски раст (b > 3) и кондициони фактор показују да јединке из ове три акумулације више повећавају телесну масу него дужину тела.

AB  - Јединке клена из акумулација Перућац, Власина, Кокин Брод и Спајићи узорковане су током лета 2017. године стајаћим мрежама (димензија 30 m × 2 m, промера окаца 28-100 mm). Мреже су остављане у води током ноћи. Свакој јединки измерене су тотална дужина тела (TL, cm) и маса тела (W, g), а одређен је и Фултонов фактор кондиције (K = W/TL3 × 100). Највеће средње дужине и масе тела (± SD) забележенe су код јединки из Кокиног брода (40,6 ± 8,4 cm и 888 ± 587 g), затим из Власине (31,3 ± 4,8 cm и 367 ± 261 g) и Перућца (27,6 ± 2,5 cm и 233 ± 88 g), док су најмање вредности забележене за Спајиће (19,7 ± 7,5 cm и 112 ± 164 g). Просечне вредности К указале су на добру кондицију испитиваних риба и кретале су се од 1,17 за Кокин брод, преко 1,09 (Власина) и 1,07 (Перућац), до 0,92 за Спајиће. Јединке са свих локалитета показале су позитиван алометријски раст – Перућац (a = –2,290; b = 3,22; r² = 0,87), Власина (a = –2,165; b = 3,14; r² = 0,96), Кокин брод (a = –2,110; b = 3,11; r² = 0,99), Спајићи (a = –2,365, b = 3,25, r² = 0,99). Позитивна алометрија указује (b > 3) да јединке повећавају своју висину и/или ширину више него што повећавају дужину тела. Ово може бити резултат онтогенетских промена у облику тела или, чешће, повећања телесне масе, на шта указују и вредности фактора кондиције.
