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  - 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  - Sterlet populations have experienced a decline during the 20th century throughout its range, mainly due to poorly regulated fisheries, pollution, habitat fragmentation and habitat loss. They still represent a species of significant economic importance in the Middle and Lower Danube, so the present study was designed to investigate genetic diversity of wild sterlet populations from the Middle and Lower Danube and Lower Tisza rivers, as a prerequisite for their effective conservation and management. By applying ten microsatellite loci, we determined that pair-wise FST values were particularly low (0.018-0.038), indicating the presence of a gene flow and a low level of sub-structuring among the assessed locations. This trend can be also observed in allele sharing distance based NJ tree. Genetic variance could be attributed almost entirely to individuals, with no detectable strong population structure. Our analysis revealed considerable variation in the detection of a genetic bottleneck. Point estimate methods revealed different effective population sizes, with the lowest value being 8.1. Our study indicated the need for a careful planning of sterlet stocking programmes.

AB  - Despite sterlet (Acipenser ruthenus L.) being a less important resource regarding caviar
production, their populations have experienced a decline during the 20th century
throughout its range, mainly due to poorly regulated fishery, pollution, habitat
fragmentation and habitat loss. Stocking programs are implemented throughout Danube
River basin, with Upper Danube populations being dependent on continuous stocking
efforts, while commercial exploitation of wild stocks in the Middle and Lower Danube
has to be compensated with stocking of larvae, fingerlings and juveniles. Selection of
proper specimens for stocking programs should be carefully conducted, since it can lead
to deleterious impact, such as reduction of effective population size, inbreeding and
outbreeding depression, and loss of locally adapted alleles. Therefore, natural
populations should be examined genetically both before and after release of hatcheryreared
juveniles. Our research on Middle and Lower Danube sterlet, suggests that
genetic variability should be attributed almost entirely to individual variability, with a
weak population structure and no clear evidence of a bottleneck and inbreeding within
populations. Also, specimens used for the supportive stocking in the Tisza River in
Hungary originated from the Danube River, so the information about gene flow between
these rivers should be carefully considered. Additionally, most of breeding programs are
focused on genetic diversity and do not acknowledge complexities of wild populations
fitness architecture. Although Middle and Lower Danube dams are recent, in regard to
sterlet population time, they create more lentic conditions that do not suit sterlet
rheophilous nature. Both our previous and current morphometric research suggests that
hatchery-reared sterlet specimens are not necessarily suited for stocking of certain
Danube River sections. Lower Danube section have a different water flow regime and
suspended sediment discharge than those in Middle Danube and in Lower Tisza River,
so the sterlet specimens are differently adapted to their environment, which is in
concordance with our findings. We suggest that both shape analysis and genetic analysis
should be applied in restocking programs.

AB  - Nase (Chodrostoma nasus L. 1758) specimens of four age classes (1+ to 4+) were caught in July 2013 in the Medjuvršje Reservoir. Concentrations of 14 metals and elements (Al, B, Ba, Cd, Co, Cr, Cu, Fe, Mn, Mo, Ni, Si, Sr, Zn) in the muscle, gills and liver were analyzed by inductively-coupled plasma optical spectrometry (ICP-OES). The highest concentrations of Al, Ba, Co, Cr, Mn, Si, Sr and Zn were detected in gills, while Cd, Cu, Fe and Mo reached the highest values in the liver. The majority of the analyzed elements were found in minimal concentrations in the muscle. Younger age classes (1+, 2+) were differentiated by higher concentrations of Mn, Sr and Zn in muscle tissue, while the older ones were mainly differentiated by higher concentrations for Ni and Cu. The youngest age class (1+) was distinguished by higher concentrations of Zn, while the oldest age class (4+) was distinguished by higher concentrations of Ba, Cu, Mo and Sr in gills. Results obtained were likely caused by differences in the physiology and feeding habits between younger (1-2+) and older (3-4+) age groups of nase.

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.

abstract = "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  - The aim of this paper was to use geometric morphometry as a helpful tool to clarify the overlap between meristic characters (such as the number of anal fin rays) of different fish identification keys employed for the two sister species, Ameiurus melas and Ameiurus nebulosus. Geometric morphometry included shape analysis of 15 landmarks on 432 specimens. The analyses showed significant differences among groups based on the sampling site, while there was no difference among groups based on the number of anal fin rays (used to distinguish species). This suggests that the use of meristic characters for the determination of these two sister species is rather questionable.

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
