AB  - Istraživanja su vršena tokom leta 2017. godine na tri akumulacije u Srbiji: Garaši, Perućac i Medjuvršje. Merenja temperature, koncentracije rastvorenog kiseonika, pH, totalno rastvorenih čestica, konduktiviteta i koncentracije hlorofila-a vršena su multiparametarskom sondom (YSI 6600 V2) od površine do 5 m dubine, sa intervalom od 1 m. Dobijeni rezultati pokazali su da se akumulacija Garaši izdvojila kao akumulacija sa najvišim sadržajem rastvorenog kiseonika i najvišom koncentracijom hlorofila a., i vodom koja je alkalna (pH>8).
AB  - This study was conducted during the summer of 2017 in three reservoirs in Serbia: Garaši,
Perućac, and Medjuvršje. Measurements of temperature, dissolved oxygen concentration, pH,
suspended particles, conductivity and concentration of chlorophyll-a were performed with a
multiparameter water quality probe (YSI 6600 V2) from water surface to 5 m depth, with an
interval of 1 m. The obtained results showed that Garaši reservoir stood out as the reservoir
with the highest dissolved oxygen contentration and the highest concentration of chlorophyll
a., and with alkaline water (pH> 8).

AB  - Since the early 1970s the spread of the Ponto-Caspian gobiids along the Serbian part of the Danube River
has been reported, mainly owing to the construction of dams and canals linking the larger rivers. The aim
of our study was to analyse the diet of the round goby Neogobius melanostomus based on the fish intestinal
contents and available food resources at selected sites in the Danube and Velika Morava rivers in Serbia.
The fish samples were collected during October 2018, at three localities: Zemun and Stari Slankamen in
the Danube River and Ljubičevski Most in the Velika Morava River. A total of 35 fish specimens were
collected and examined. The analysis of the intestinal contents showed that N. melanostomus fed mainly
on representatives of Gammaridae (Dikerogammarus sp.), insect larvae (Trichoptera, Chironomidae),
Gastropoda, Bivalvia (Dreissena sp., Corbicula sp.), and Oligochaeta. The diet of fish from the Velika
Morava River consisted mostly of Oligochaeta and Gammaridae, while the diet of fish from the Danube
River consisted of larvae of Trichoptera and mollusks.

AB  - The aim of this work was to compare the efficiency of two different methods for fish sampling and to assess the influence of the twilight period on the catch of gobiids along the Danube River in Serbia. The samplings were performed by electrofishing and beach seining in inshore parts of the Danube River with water depth up to 120 cm at four locations: Novi Sad, Belgrade, Tekija, and Prahovo, in October 2012 and September 2013. At each location, the samplings were performed at 17:30, 18:30, 19:30 and 20:30. Totally, 539 gobiids were caught. The highest number of specimens (218) was registered at Tekija, while lower numbers were registered at Belgrade (192) and Prahovo (117), and only 12 specimens were caught at Novi Sad. The catch of the round goby Neogobius melanostomus and monkey goby Neogobius fluviatilis was more efficient by beach seining than by electrofishing, whereas the catch of the tubenose goby Proterorhinus semilunaris was more efficient by electrofishing. Both methods had similar efficiency in catching the bighead goby Ponticola kessleri and racer goby Babka gymnotrachelus. The species diversity and number of the caught specimens were the highest at 18:30. All five species were recorded at Belgrade, Tekija and Prahovo, while only the monkey goby and racer goby were caught at Novi Sad. The methods used in this study showed good efficiency in catching gobiids, especially at dusk. Even though these methods are difficult to apply in certain habitats, they could be highly relevant in the regular monitoring of gobiids along the inshore parts of rivers.

The highest number of specimens (218) was registered at Tekija, while lower numbers were registered at Belgrade (192) and Prahovo (117), and only 12 specimens were caught at Novi Sad. The catch of the round goby Neogobius melanostomus and monkey goby Neogobius fluviatilis was more efficient by beach seining than by electrofishing, whereas the catch of the tubenose goby Proterorhinus semilunaris was more efficient by electrofishing. Both methods had similar efficiency in catching the bighead goby Ponticola kessleri and racer goby Babka gymnotrachelus. The species diversity and number of the caught specimens were the highest at 18:30. All five species were recorded at Belgrade, Tekija and Prahovo, while only the monkey goby and racer goby were caught at Novi Sad. The methods used in this study showed good efficiency in catching gobiids, especially at dusk. Even though these methods are difficult to apply in certain habitats, they could be highly relevant in the regular monitoring of gobiids along the inshore parts of rivers.",

AB  - In this study, 20 heavy metals and trace elements (Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Hg, Li, Mg, Mn, Mo, Ni, Pb, Si, Se, Sr and Zn) were analyzed in different tissues (muscle, liver, intestine, feather and bone) of the great cormorant (Phalacrocorax carbo) and in different tissues (muscle, liver, gills, kidney and gonad) of their main prey (common carp Cyprinus carpio and Prussian carp Carassius gibelio) during the nesting season. Cormorant and fish specimens were collected at the Ecka Fishing Farm (Serbia) and from the nearby river. Principal components analysis (PCA) showed that cormorant livers were differentiated from other four tissues by higher concentrations of Hg, Fe, Cu and Mo, feathers by higher concentrations of Al and Si, and bones by higher concentrations of Sr and Mg. Differentiation among the three age classes of cormorants was observed only with regard to elemental concentrations in their feathers: subadult cormorants were differentiated by higher Hg and Zn concentrations, while the adults were separated by higher concentrations of Fe. In comparison with their prey (common carp and Prussian carp) cormorants were differentiated by higher concentrations of Fe, Hg and Cu in the muscle. Toxic mercury concentrations above 4 mu g g(-1) dw were determined in the liver of juvenile cormorants, as well as in the liver and feathers of subadults. Hg concentrations were significantly correlated among all studied tissues. Cormorant had significantly higher concentrations of Fe and Hg in muscle and liver than two studied fish species.

AB  - Pontic shad (Alosa immaculata Bennet 1835) is an anadromous species that lives in the heavily polluted north-western part of the Black Sea and migrates into the Danube River to spawn To assess their heavy metal contamination levels, samples of Politic shad were collected at 863 river kilometre of the Danube River Muscle, liver and gill samples were prepared using microwave digestion. and the analysis of Al, As, Cd, Cu, B. Ba. Fe, Mg. Sr. Zn. Li, Co, Cr. Mn. Mo, Ni and Pb was performed with inductively-coupled plasma-optic emission spectroscopy (ICP-OES). Significant differences in concentrations of analyzed elements were observed among different tissues, as well as between the genders Al, Sr, Ba. Mg, and Li had the highest concentrations in gills, while Cd. Cu, Zn. Fe and B were highest in the liver While the muscle had the lowest concentrations of most of the analyzed elements, it had the highest concentration of As. This study has revealed that the concentrations of Cd and As in Politic shad muscle tissue were above the maximum acceptable concentrations for human consumption, thus precautions need to be taken in order to prevent future heavy metal contamination (C) 2010 Elsevier B V All rights reserved
