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 Gradište (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  - The aim of this study was to describe biometric and feeding characteristics of highly invasive species Perccottus glenii in the investigated locality. A total of 85 fish were electrofished 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 factor 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, unidentified and terrestrial insects were identified in the diet. Generally, the diet is entirely composed 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 paddlefish (Polyodon spathula) was first introduced to Europe in 1974, mainly due to its potential for rearing in natural polyculture ponds and large temperate reservoirs. The information on the history of paddlefish aquaculture efforts in Europe is scarce, as well as data on current paddlefish aquaculture status and trends. In addition, there is a lack of data on its presence and potential establishment in the wild, while its invasive potential and associated risks and impacts are largely unknown. In order to evaluate its current status in Europe, we conducted a survey among scientists, aquaculture producers and other stakeholders, and reviewed literature and data on the Internet. Based on the results obtained, we discuss the potential and the challenges in European paddlefish aquaculture development, and analyze paddlefish invasive potential and risks associated with its naturalization. Paddlefish aquaculture is well established only regionally in Europe, but offers relatively high potential for further development in pond farms. Nevertheless, future development will require careful planning, especially regarding market development and improved marketing strategies. While paddlefish likely represents a low-risk invader, improved control and reporting on trade and intentional and unintentional releases will be required. Given the lack of knowledge on potential impacts following its introduction, due caution seems highly advisable.

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.
