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  - 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 Kruscica reservoir (intended for water supply) and Meduvrsje 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 Meduvrsje 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 Kruscica 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 Meduvrsje 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 Kruscica 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  - Fishery in the Danube River basin has been characterised over the past century by increasing fishing levels, illegal fishing practices and poor regulations. However, there is a remarkable lack of available information on the actual status of fish stocks, as well as on the trends and sustainability of fisheries, which poses a problem for the development of adequate policy and management measures. In this study, we assessed the trends in the commercial fishery in the Middle Danube in Serbia during 1969-1989 and 2006-2010 by evaluating the temporal changes in life history-related indicators that might point out unsustainable fishing pressures. Moreover, we present the approach of using the catch-weighted mean egg-per-recruit (EPR) index as a proxy for the overall resilience of fish stocks to fishing. Results indicated a marked shift towards smaller fish that mature earlier and have a shorter lifespan. Landings also shifted towards species at lower trophic levels, with a mean trophic level decline at a rate of approximately 0.16 per decade. Results indicated likely presence of the fishing through the food web' phenomenon. At the same time, catch-weighted community mean of the 20% EPR threshold ratio (EPR20%) increased by 4.2%, indicating the increase of the overall resilience to fishing of the exploited species. Obtained results indicated the importance of using such metrics for the assessments of trends in fishery. The approach and results presented here could be of interest for the scientific community and stakeholders involved in fishery management.

AB  - The concentrations of As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se and Zn in the muscle, gills, liver and intestine of the wels catfish (Silurus glanis) from the Danube River were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The aim of the study was to determine whether in complex muscle/skin, gill filament/gill arch, proximal/distal liver and proximal/median/distal intestine samples, particular components differ in concentrations of the analyzed elements. Results indicated that there were no differences in the accumulation of different elements between the proximal and distal liver segments and between the proximal and median intestine sections. Conversely, elemental accumulation patterns in muscle and skin differed significantly. Significant differences were also observed between the gill arch and filaments, as well as between the distal and the two upper intestine sections. Findings indicated the importance of detailed reporting of tissue sampling, i. e. whether the skin was included in the muscle sample, as well as if the gill arch and filaments were analyzed together. Due to a potential bias that can be produced by different muscle/skin or gill arch/filament ratios included in the sample, we strongly recommend that they should not be analyzed together. Results of the present study might be of interest to the scientific community and stakeholders involved in aquatic ecosystem monitoring programs.

AB  - Studies of metal accumulation in fish are mainly focused on the muscle tissue, while the metal accumulation patterns in other tissues have been largely neglected. Muscle is not always a good indicator of the whole fish body contamination. Elemental accumulation in many fish tissues and organs and their potential use in monitoring programs have not received proper attention. In the present study, As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn concentrations were assessed by inductively coupled plasma mass spectrometry (ICP-MS) in the following 14 tissues of the wels catfish (Silurus glanis) from the Danube River: muscle, gills, spleen, liver, kidneys, intestine, gizzard, heart, brain, gallbladder, swim bladder, vertebra, operculum, and gonads. A high level of differential elemental accumulation among the studied tissues was observed. The maximum overall metal accumulation was observed in the vertebra, followed by the kidneys and liver, with the metal pollution index (MPI) values of 0.26, 0.25, and 0.24, respectively. The minimum values were observed in the gallbladder, muscle, brain, and swim bladder, with MPI values of 0.03, 0.06, 0.07, and 0.09, respectively. Average metal concentrations in the fish muscle were below the maximum allowed concentrations for human consumption. The mean As, Cd, Pb, Cu, Fe, and Zn concentrations in the muscle were 0.028, 0.001, 0.001, 0.192, 3.966, and 3.969 mu g/g wet weight, respectively. We believe that the presented findings could be of interest for the scientific community and freshwater ecosystem managers. There is a need for further research that would assess less studied tissues in different fish species.
