The study focuses on the pristine rivers of the Biebrza National Park (BNP), an extensive area of wetlands, which holds significant biodiversity importance on a European scale. The aim of this work was to identify the taxonomic resources of the river network of this area and to compare the biodiversity of various aquatic organisms, and moreover, ev...
The Enemy Release Hypothesis (ERH) proposes that the success of bioinvasions is attributable to lower enemy pressure on invasive species compared to native ones, giving a competitive advantage for invaders. In line with the hypothesis, we previously observed in northern European bodies of fresh water that invasive bivalves were subject to lower par...
Enemy Release Hypothesis (ERH) proposes that the success of bioinvasions is contributed by lower enemy pressure on invasive species compared to native ones, giving a competitive advantage for invaders. In line with EHR, we earlier observed that the invasive bivalves had a lower parasite pressure than the sympatric native freshwater mussels in north...

The European perch (Perca fluviatilis L.) is a common freshwater fish which is widely distributed in Europe and Asia and has been successfully introduced to New Zealand and Australia. It is the intermediate and definitive host of many parasites, especially endoparasites, such as trematodes, cestodes and nematodes (Bikhovskaya-Pavlovskaya and Kulako...
An increasing threat to local, native freshwater mussels (Unionida)—an ecologically important but globally alarmingly declining group—is the invasion by exotic bivalves. The Enemy Release Hypothesis predicts that introduced species should benefit from enemy-mediated competition because they are less likely to be harmed by natural enemies, such as p...
The aim of the study was to determine selected characteristics of surimi-like material (SLM) made from the muscle tissues of Sinanodonta woodiana (Lea, 1834) freshwater mussels. The research material consisted of unwashed mussel muscle homogenate as the control sample—C, mussel muscle tissue twice washed with water (SLM-W) and sample washed with Na...
Securing adequate supply of high-quality water is of increasing global importance and relies in large part on ecosystem services provided by freshwater biota. Unionid mussels are important keystone species and habitat engineers that shape freshwater ecosystems through water filtration, nutrient cycling and provision of habitats; their rapid global...

Abstract: We summarise the current knowledge about the Polish population of the Chinese pond mussel. At least 53 locations of the Chinese pond mussel have been confirmed in Poland taking into consideration a literature survey and our own research data comprising new unreported sites. S. woodiana is mostly present in fish ponds (69.8%) but for the l...
The inferior pharyngeal bones are a characteristic feature of the Cyprinidae. Morphology of inferior pharyngeal bones is important in the diagnosis of carnivorous food, or determining the diet of fishes. Due to the lack of literature data, the aim of the study was to examine the morphology of the inferior pharyngeal bone in detail. 102 Blicca bjoer...
Bivalves of the family Unionidae live partly buried in the sediments, usually with the posterior part of their shell exposed to the water column to enable filtration. This exposed part of the shell can therefore serve as a substratum for zebra mussels (Dreissena polymorpha), which limit the host’s ability to feed, move, and breed. We analyzed image...
The research analyses the influence of the number of washings and different washing solutions, on the recovery of dry matter and protein in a preparation made from freshwater mussel Sinanodonta woodiana, (Lea, 1834). The study involved qualitative and quantitative characterisation of mussel protein preparation (MPP) obtained by electrophoretic sepa...
Freshwater mussels (Unionoida) are among the most imperiled animals on Earth. Invasive mussels pose a significant threat to native mussel species. Enemy Release Hypothesis (ERH) explains the success of invasive species by lack of enemies. ERH suggests that invasive species are ‘released’ from their natural enemies – such as parasites – when they le...
So far in Poland, the Asian clam Corbicula fluminea has been reported from the Oder (Odra) and Vistula River. Its new population has been discovered in the Warta-Gopło Canal in Konin (central Poland), where water temperature can reach 34°C, as the canal is a part of a power plant lake cooling system. The spatial distribution of C. fluminea was foun...
The Asiatic bivalve Sinanodonta woodiana (Lea, 1834), which is more and more widespread in all parts of Europe, in Poland has been mostly reported from lentic waters, especially fish ponds. In contrast to some other European countries, no data have been published on its presence in rivers of Poland. In 2015, monitoring was carried out in the lower...
Oxbow lakes are typical elements of meandering watercourses and are considered to be key components of floodplains of natural rivers. A permanent connection with the river promotes the use of these water bodies by ichthyofauna as spawning grounds, shelter for fry, feeding and wintering grounds. The aim of this study was to determine which rheophili...
The aim of the work was to determine the total cholesterol content in the meat of perch (Perca fluviatilis L.), Prussian carp (Carassius auratus gibelio), ruffe (Gymnocephalus cernua L.) and sander (Sander lucioperca L.) collected from Lake Gopło, Lake Góreckie and to compare the cholesterol content between females and males of ruffe caught in diff...
The aim of this study was to examine the thermal denaturation properties of proteins from fresh and frozen pond mussels Anodonta woodiana by differential scanning calorimetry (DSC). The A. woodiana (Lea, 1834) mussels were collected from the bottom of a lake located in West Poland. Three parts of the mussel: adductor muscle (AM), foot muscle (FO) a...
ABSTRACT
Biological invasions are commonly observed in both the natural habitats and those which are altered by human activities. An understanding
of the mechanisms involved in the successful introduction, establishment and invasion of exotic taxa is essential in predicting
of changes in biodiversity and community structure. Symbiont-mediated inter...

The discovery of a shell of the Chinese pond mussel in 1998 and further confirmation of this species indicate that a reservoir with natural thermal conditions is the oldest species location in Poland. Growth increments of an archival shell do not fall within the ranges obtained by this species in Konin lakes. They are, however, close to population...
The study of fish ponds have confirmed the presence of nine new locations of Anodonta woodiana in Poland, with strong and vital populations. These are examples of Chinese pond mussels accidentally introduced along with fish imports. Comparison of known localities shows that more mussels are in eastern Poland, from which the migration path of A. woo...
ABSTRACT: Sinanodonta woodiana (Lea 1834) is a new component of malacofauna and this condition enhances a new adaptation of predators preying on it. In 2010, during the autumn bird migration, an oystercatcher was observed feeding on this clam species alien to European fauna in the area of drained fish ponds (western Poland). The clams chosen by the...
Abstrakt: Najwyższymi formami ochrony przyrody w Polsce są parki naro-dowe i rezerwaty. Niezwykle istotnym elementem tych struktur są ekosy-stemy wodne. Jednym z negatywnych zjawisk, będących konsekwencją nie-prawidłowej ochrony wód i ekosystemów wodnych jest rozprzestrzenianie gatunków obcych w ichtiofaunie i wypieranie gatunków rodzimych. Aby móc...
