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  - 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.

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  - 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.

abstract = "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.",

AB  - Allochthonous and invasive species are among the main factors leading to biodiversity loss which
further threatens the ecosystem functioning, stability and resilience. A modern way of life and climate changes accelerated and increased the spread of invasive species. Although many ecosystems are facing this problem, the most endangered ones are slow-flowing/stagnant shallow waters. The black bullhead (Ameiurus melas) is recognized as one of the most successful non-native fish species in European freshwaters. Regarding its mitigation, selective mass removal is considered as an effective method to reduce the abundance of the local population. This biomanipulative measure undoubtedly affects other ecosystem components, so monitoring of organisms from different trophic levels is crucial for assessing the impact and success of the whole process.
The aim of this study was to detect and examine the changes in phytoplankton structure and
abundance, as a response to the mass removal of the black bullhead.
Selective removal took place in the lowland Ponjavica River in the same-named Nature Park in
Serbia with the domination of black bullhead and urgent need for biodiversity recovery. The removal project was conducted from June to October 2018 and April to October 2019. The removal process was conducted at three localities along the protected part of the Ponjavica River. Along with fish removal, phytoplankton samples for qualitative and quantitative analyses were collected by plankton net and Van Dorn bottle, respectively. The taxonomic literature was used for qualitative analysis, while the Utermöhl method was conducted for the assessment of phytoplankton abundance.
More than 200 algal taxa were detected in Ponjavica phytoplankton. Phytoplankton abundance at
each of the localities showed similar dynamics ranged from minimal 156914 cell/ml in June, to maximal 1038946 cell/ml in August 2018. Cyanobacteria were the dominant group with more than 98% in total cell number from August to October. Three invasive and potentially toxic cyanobacteria (Raphidiopsis raciborskii, Sphaerospermopsis aphanizomenoides, Raphidiopsis mediterranea) were registered with 61% in total cell number in August, 59% in September and 38% in October 2018. Phytoplankton abundance decreased (by almost half) in the second year of the project, together with the share of invasive and potentially toxic cyanobacteria in the total cell number and particularly a number of individuals. 
The black bullhead and Raphidiopsis raciborskii are considered as the most successful invasive
species among fish and cyanobacteria, respectively, and both are detected in the Ponjavica River. Our results showed that mass removal of black bullhead caused a decrease in phytoplankton abundance and also portion of present invasive cyanobacteria without newly occurred ones, while in the case of ichthyofauna other species increased the population abundance due to free niche.
Great efforts are being made to find adequate solutions for invasive species removal but a unique and successful method has not been found so far. The selective mass removal is the best method to decrease the black bullhead abundance and the results of this research indicated that the process could have a positive effect on decreasing the abundance of invasive species at the base of the trophic chain.

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.

AB  - Теренска истраживања спроведена су у октобру 2021. године на реци Ибар (код села Павлица) у циљу утврђивања еколошког статуса и квалитета воде на основу квалитативног и квантитативног састава заједнице риба. Узорковање ихтиофауне извршено је методом електрориболова (низводно од бране) и стајаћим мрежама (у акумулацији узводно од бране). Укупан индекс сапробности (S) израчунат је према методи Pantle-Buck,1 а Shannon-ов индекс (H)2 коришћен је за процену диверзитета заједнице. Уловљено је 658 риба у оквиру 13 различитих врста – клен (Squalius cephalus), скобаљ (Chondrostoma nasus), кркуша (Gobio obtusirostris), поточна мрена (Barbus balcanicus), речна мрена (B. barbus), двопругаста уклија (Alburnoides bipunctatus), уклија (Alburnus alburnus), гаовица (Rhodeus amarus), носара (Vimba vimba), гргеч (Perca fluviatilis), бодорка (Rutilus rutilus), бабушка (Carassius gibelio) и сом (Silurus glanis). Уклија и кркуша чиниле су скоро 50% узорка. Вредност S износила је 2,02, тако да вода испитиване реке припада β мезосапробној води II класе бонитета, тј. умерено загађеној води. Иста вредност забележена је и за H (H = 2,02), па према квалитету воде река Ибар спада у II-III класу. Како река Ибар узводно од места узорковања прима отпадне воде из Рашке, овај резултат је очекиван и у складу је са резултатима претходних истраживања квалитета воде.

Уловљено је 658 риба у оквиру 13 различитих врста – клен (Squalius cephalus), скобаљ (Chondrostoma nasus), кркуша (Gobio obtusirostris), поточна мрена (Barbus balcanicus), речна мрена (B. barbus), двопругаста уклија (Alburnoides bipunctatus), уклија (Alburnus alburnus), гаовица (Rhodeus amarus), носара (Vimba vimba), гргеч (Perca fluviatilis), бодорка (Rutilus rutilus), бабушка (Carassius gibelio) и сом (Silurus glanis). Уклија и кркуша чиниле су скоро 50% узорка. Вредност S износила је 2,02, тако да вода испитиване реке припада β мезосапробној води II класе бонитета, тј. умерено загађеној води. Иста вредност забележена је и за H (H = 2,02), па према квалитету воде река Ибар спада у II-III класу. Како река Ибар узводно од места узорковања прима отпадне воде из Рашке, овај резултат је очекиван и у складу је са резултатима претходних истраживања квалитета воде.",

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.

AB  - Samples of pikeperch (20 in total) were caught at Garaši reservoir during the summer of 2017. The objectives of this research was to analyse the concentrations of 17 organochlorine pesticides (aldrin, α-HCH, β-HCH, γ-HCH, δ-HCH, 4,4’-DDD, 4,4’-DDE, 4,4’-DDT, dieldrin, endosulfan I, endosulfan II, endosulfan sulfate, endrin, endrin aldehyde, heptachlor, heptachlor epoxide, and metoxychlor) in fish muscle by gas chromatography with mass spectrometric (GC-MS) detection. QuEChERS method was used for extraction and clean-up of pesticide residues from muscle tissue. Three phenyl phosphate (TPP) was used as an internal standard. Concentrations of 4,4’-DDD, 4,4’-DDE, 4,4’-DDT, heptachlor and heptachlor epoxide in fish muscle were compared with the maximum allowed concentrations (MAC) in fish meat set by the national legislation of Serbia. This reservoir is used as a drinking water source. Therefore, the hypothesis was that it was exposed to low organic pollution. The concentrations of all analyzed pesticides were below the detection limits. In conclusion, there is no health risk for consumption of pikeperch from Garaši reservoir.

abstract = "Samples of pikeperch (20 in total) were caught at Garaši reservoir during the summer of 2017. The objectives of this research was to analyse the concentrations of 17 organochlorine pesticides (aldrin, α-HCH, β-HCH, γ-HCH, δ-HCH, 4,4’-DDD, 4,4’-DDE, 4,4’-DDT, dieldrin, endosulfan I, endosulfan II, endosulfan sulfate, endrin, endrin aldehyde, heptachlor, heptachlor epoxide, and metoxychlor) in fish muscle by gas chromatography with mass spectrometric (GC-MS) detection. QuEChERS method was used for extraction and clean-up of pesticide residues from muscle tissue. Three phenyl phosphate (TPP) was used as an internal standard. Concentrations of 4,4’-DDD, 4,4’-DDE, 4,4’-DDT, heptachlor and heptachlor epoxide in fish muscle were compared with the maximum allowed concentrations (MAC) in fish meat set by the national legislation of Serbia. This reservoir is used as a drinking water source. Therefore, the hypothesis was that it was exposed to low organic pollution. The concentrations of all analyzed pesticides were below the detection limits. In conclusion, there is no health risk for consumption of pikeperch from Garaši reservoir.",

AB  - The black bullhead is an invasive species that forms dense populations and has a negative impact on the native ichthyofauna. Recent studies indicate that it is one of the most dominant invasive fish species in Serbian waters. Feeding habits based on stomach contents of individuals caught in Lake Sava were analyzed as a first step towards evaluating its possible negative impact on the native fish fauna of the lake. The following indices for diet analysis were applied: vacuity index, frequency of occurrence, numerical abundance and prominence value. Trophic niche breadth and seasonal trophic diversity were calculated using the Shannon's index. The diet spectrum comprised 16 different prey categories from five groups: Mollusca, Crustacea, Insecta, Teleostei and plants. Fish were the main prey in all seasons, followed by aquatic invertebrates. Plant material and terrestrial insects were used as food in relatively small quantities. Predation on fish eggs was also detected. Our research confirmed that this species is an opportunistic generalist. An ontogenetic diet shift was also detected. The lowest value of trophic diversity was found in age 1+ individuals (H=1.39), while the highest was found in age 3+ individuals (H=2.00). The widest niche breadth was recorded in spring 2011 (H=2.12).

AB  - In recent decades, the Amur sleeper (Perccottus glenii) is one of the most impressive east-to-west invaders of European inland waters, but there are insufficient data on its biology in the countries it has entered. Specimens of two sets of samples from November 2015 (n=25) and October 2016 (n=39) were caught in the Danube River channel near Veliko Gradiste (Serbia) by electrofishing. Thirty morphometric and eight meristic characteristics of the collected fish were measured with the aim of describing the general body shape in more detail using the "point-to-point" method. This is the first attempt to obtain morphometric and meristic characteristics of Amur sleeper caught in Serbia. The results revealed a relatively low variability in the morphometric and meristic characters of the studied population. When compared to other studies, there was a great variability of the studied characteristics between geographically distant European populations that inhabit different water body types. Female fish had more robust bodies compared to males of the same length, while males had longer pectoral, anal and dorsal fins. Additionally, 2+ individuals had more robust heads and jaws, as well as longer anterior parts of the body compared to 1+ individuals of the same size.

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  - During the last decades in the freshwater system in Serbia 27 allochthonous fish species appeared, and they can be divided into two groups. In the first group are representatives of fish fauna which are originally from Asia and they are intentionally introduced into open waters and aquaculture in Serbia, while the second group represent the migrants spreading their range from the Black Sea into freshwater systems. Some of these species already have established populations. Representatives of marine fauna that inhabit fresh-water systems in Serbia are: Syngnathus abaster, Neogobius fluviatilis, Babka gymnotra-chelus, Ponticola kessleri, Neogobius melanostomus, Proterorhinus (marmoratus) semi-lunaris, Gasterosteus aculeatus, Knipowitschia caucasica, Morone morone x Morone saxatilis. Gobiids extended their geographical distribution outside their native range and expanded their area of distribution in throughout whole Danube River Basin, while for the other specimens there are no literature data about established populations.

AB  - During the last decades in the freshwater system in Serbia 32 allochthonous fish species appeared, and they can be divided into five groups according to their region of origin: Asian, Ponto-Caspian, North American, South American, and Europe without Ponto-Caspian region. The Asian and Ponto-Caspian species are the most numerous. In the first group are representatives of fish fauna which are originally from Asia and they are intentionally introduced into open waters and aquaculture in Serbia, while the second group represents the migrants spreading their range from the Black Sea into freshwater systems. Some of these species already have established populations. Representatives of marine origin that inhabit freshwater systems in Serbia are: Syngnathus abaster, Neogobius fluviatilis, Neogobius melanostomus, Babka gymnotrachelus, Ponticola kessleri, Proterorhinus semilunaris, Knipowitschia caucasica, Benthophyllus stellatus, Gasterosteus aculeatus, Morone saxatilis x Morone chrysops. Gobiidae and Sygnathidae extended their geographical distribution outside their native range and expanded their area of distribution throughout whole Danube River Basin, while for the other specimens there are no literature data about established populations.
AB  - Tokom poslednjih dekada u rijekama i jezerima u Srbiji su se pojavile 32 alohtone vrste riba i prema regiji njihovog porijekla mogu se podijeliti u pet grupa: Azijske, Ponto-Kaspijske, Sjeverno Američke i Evropske bez Ponto-Kaspijskog regiona. Azijske i Ponto-Kaspijske su najbrojnije. U prvoj grupi su predstavnici riblje faune koji su porijeklom iz Azije i one su namjerno unesene u otvorene vode i akvakulturu Srbije, dok druga grupa predstavlja migrante iz Crnog mora koji šire svoj areal u sistemu rijeka i jezera. Neke od ovih vrsta su već uspostavile svoje populacije. Predstavnici morskog porijekla koji naseljavaju rijeke i jezera u Srbiji su: Syngnathus abaster, Neogobius fluviatilis, Neogobius melanostomus, Babka gymnotrachelus, Ponticola kessleri, Proterorhinus semilunaris, Knipowitschia caucasica, Benthophyllus stellatus, Gasterosteus aculeatus, Morone saxatilis x Morone chrysops. Gobiidae i Sygnathidae su proširile svoju geografsku distribuciju van nativnog areala i proširile distribuciju kroz cijeli bazen rijeke Dunav, dok za druge vrste nema literaturnih podataka o uspostavljenim populacijama.

AB  - The aim of this study was to describe biometric and feeding characteristics of highly in-vasive species Perccottus glenii in the investigated locality. A total of 85 fish were elec-trofished 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 fac-tor 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, uniden-tified and terrestrial insects were identified in the diet. Generally, the diet is entirely com-posed 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  - 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.
